 <p>There is a lot of software freely available for Unix-based
 systems, which is usually available in form of the source code. Before
 such software can be used, it needs to be configured to the local
 system, compiled and installed, and this is exactly what The NetBSD
 Packages Collection (pkgsrc) does. pkgsrc also has some basic commands
 to handle binary packages, so that not every user has to build the
 packages for himself, which is a time-costly task.</p>
 <p>pkgsrc currently contains several thousand packages,
       including:</p>

 <p>&#8230; just to name a few.</p>
 <p>pkgsrc has built-in support for handling varying dependencies,
       such as pthreads and X11, and extended features such as IPv6 support on
       a range of platforms.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="why-pkgsrc"></a>1.1.1. Why pkgsrc?</h3></div></div></div>
 <p>
 pkgsrc provides the following key features:
 </p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>Easy building of software from source as well as the creation
   and installation of binary packages. The source and latest
   patches are retrieved from a master or mirror download site, checksum
   verified, then built on your system. Support for binary-only
   distributions is available for both native platforms and NetBSD
   emulated platforms.</p></li>
 <li class="listitem"><p>All packages are installed in a consistent directory tree,
   including binaries, libraries, man pages and other
   documentation.</p></li>
 <li class="listitem"><p>Tracking of package dependencies automatically, including when
   performing updates, to ensure required packages are installed. The
   configuration files of various packages are handled automatically during
   updates, so local changes are preserved.</p></li>
 <li class="listitem"><p>Like NetBSD, pkgsrc is designed with portability in mind and
   consists of highly portable code. This allows the greatest speed of
   development when porting to a new platform. This portability also
   ensures that pkgsrc is <span class="emphasis"><em>consistent across all
   platforms</em></span>.</p></li>
 <li class="listitem"><p>The installation prefix, acceptable software licenses,
   international encryption requirements and build-time options for a
   large number of packages are all set in a simple, central
   configuration file.</p></li>
 <li class="listitem"><p>The entire source (not including the distribution files) is
   freely available under a BSD license, so you may extend and adapt
   pkgsrc to your needs. Support for local packages and patches is
   available right out of the box, so you can configure it specifically
   for your environment.</p></li>
 </ul></div>
 <p>The following principles are basic to pkgsrc:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><span class="quote">&#8220;<span class="quote">It should only work if it's right.</span>&#8221;</span>
 &mdash; That means, if a package contains bugs, it's better to find
 them and to complain about them rather than to just install the package
 and hope that it works. There are numerous checks in pkgsrc that try to
-find such bugs: Static analysis tools (<a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkglint/README.html" target="_top"><code class="filename">pkgtools/pkglint</code></a>), build-time checks (portability
+find such bugs: Static analysis tools (<a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkglint/README.html" target="_top"><code class="filename">pkgtools/pkglint</code></a>), build-time checks (portability
 of shell scripts), and post-installation checks (installed files,
 references to shared libraries, script interpreters).</p></li>
 <li class="listitem"><p><span class="quote">&#8220;<span class="quote">If it works, it should work everywhere</span>&#8221;</span>
 &mdash; Like NetBSD has been ported to many hardware architectures,
 pkgsrc has been ported to many operating systems. Care is taken that
 packages behave the same on all platforms.</p></li>
 </ul></div>

 <p>pkgsrc consists of both a source distribution and a binary
 distribution for these operating systems. After retrieving the required
 source or binaries, you can be up and running with pkgsrc in just
 minutes!</p>
 <p>pkgsrc was derived from FreeBSD's ports system, and
       initially developed for NetBSD only. Since then, pkgsrc has
       grown a lot, and now supports the following platforms:</p>

 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term">Package</span></dt>
 <dd><p>A set of files and building instructions
 	    that describe what's necessary
 	    to build a certain piece of software using
             pkgsrc. Packages are traditionally stored under
 	    <code class="filename">/usr/pkgsrc</code>,

 	    referred to as <code class="varname">PKGSRCDIR</code>.</p></dd>
 <dt><span class="term">The NetBSD package system</span></dt>
 <dd><p>This is the former name of <span class="quote">&#8220;<span class="quote">pkgsrc</span>&#8221;</span>.  It
 	  is part of the NetBSD operating system and can be bootstrapped
 	  to run on non-NetBSD operating systems as well.  It handles
 	  building (compiling), installing, and removing of
 	  packages.</p></dd>
 <dt><span class="term">Distfile</span></dt>
 <dd><p>This term describes the file or files that are
 	    provided by the author of the piece of software to
 	    distribute his work. All the changes necessary to build on
 	    NetBSD are reflected in the corresponding package. Usually
 	    the distfile is in the form of a compressed tar-archive,
 	    but other types are possible, too. Distfiles are usually
 	    stored below
 	    <code class="filename">/usr/pkgsrc/distfiles</code>.</p></dd>
 <dt><span class="term">Port</span></dt>
 <dd><p>This is the term used by FreeBSD and OpenBSD people
 	    for what we call a package.
 	    In NetBSD terminology, <span class="quote">&#8220;<span class="quote">port</span>&#8221;</span> refers to a different
 	    architecture.</p></dd>
 <dt><span class="term">Precompiled/binary package</span></dt>
 <dd>
 <p>A set of binaries built with pkgsrc from a distfile
 	    and stuffed together in a single <code class="filename">.tgz</code>
 	    file so it can be installed on machines of the same
 	    machine architecture without the need to
 	    recompile. Packages are usually generated in
 	    <code class="filename">/usr/pkgsrc/packages</code>; there is also
 	    an archive on <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/" target="_top">ftp.NetBSD.org</a>.</p>
 <p>Sometimes, this is referred to by the term <span class="quote">&#8220;<span class="quote">package</span>&#8221;</span> too,

 <p>Before you download and extract the files, you need to decide
 where you want to extract them. When using pkgsrc as root user, pkgsrc
 is usually installed in <code class="filename">/usr/pkgsrc</code>. You are though
 free to install the sources and binary packages wherever you want in
 your filesystem, provided that the pathname does not contain white-space
 or other characters that are interpreted specially by the shell and some
 other programs. A safe bet is to use only letters, digits, underscores
 and dashes.</p>

 <p>Before you download any pkgsrc files, you should decide
 	whether you want the <span class="emphasis"><em>current</em></span> branch or the
 	<span class="emphasis"><em>stable</em></span> branch. The latter is forked on a
 	quarterly basis from the current branch and only gets modified
 	for security updates. The names of the stable branches are built
 	from the year and the quarter, for example
-	<code class="literal">2017Q3</code>.</p>
+	<code class="literal">2018Q1</code>.</p>
 <p>The second step is to decide <span class="emphasis"><em>how</em></span> you
 	want to download pkgsrc. You can get it as a tar file or via CVS.
 	Both ways are described here.</p>
 <p>Note that tar archive contains CVS working copy.
 	Thus you can switch to using CVS at any later time.</p>

 	which are described in detail in <a class="xref" href="#ftp-layout" title="Appendix C. Directory layout of the pkgsrc FTP server">Appendix C, <i>Directory layout of the pkgsrc FTP server</i></a>.</p>
 <p>The tar archive for the current branch is in the directory

 <p>This will create the directory <code class="filename">pkgsrc/</code>
 	in your <code class="filename">/usr/</code> directory and all the package source
 	will be stored under <code class="filename">/usr/pkgsrc/</code>.</p>
 <p>To fetch the pkgsrc current branch, run:</p>

 <p>Refer to the <a class="ulink" href="http://www.NetBSD.org/mirrors/#anoncvs" target="_top">list of available mirrors</a> to choose a faster CVS mirror, if needed.</p>
 <p>If you get error messages from <code class="literal">rsh</code>, you need to set CVS_RSH variable. E.g.:</p>

 </pre>
 <p>Refer to documentation on your command shell how to set CVS_RSH=ssh permanently.
 	For Bourne shells, you can set it in your <code class="filename">.profile</code>
 	or better globally in <code class="filename">/etc/profile</code>:</p>
 <pre class="programlisting">
 # set CVS remote shell command

 <p>By default, CVS doesn't do things like most people would expect it to do.
 	But there is a way to convince CVS, by creating a file called <code class="filename">.cvsrc</code>
 	in your home directory and saving the following lines to it.
 	This file will save you lots of headache and some bug reports, so we strongly recommend it.
 	You can find an explanation of this file in the CVS documentation.</p>

 <p>The preferred way to keep pkgsrc up-to-date is via CVS
 	(which also works if you have first installed it via a tar
 	file). It saves bandwidth and hard disk activity, compared to
 	downloading the tar file again.</p>

 <div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Warning</h3>
 <p>When updating from a tar file, you first need to
 	completely remove the old pkgsrc directory. Otherwise those
 	files that have been removed from pkgsrc in the mean time will
 	not be removed on your local disk, resulting in inconsistencies.
 	When removing the old files, any changes that you have done to
 	the pkgsrc files will be lost after updating. Therefore updating
 	via CVS is strongly recommended.</p>
 </div>
 <p>Note that by default the distfiles and the binary packages
 	are saved in the pkgsrc tree, so don't forget to rescue them
 	before updating. You can also configure pkgsrc to store distfiles
         and packages in directories outside the pkgsrc tree by setting the
 	<code class="varname">DISTDIR</code> and <code class="varname">PACKAGES</code>
 	variables. See <a class="xref" href="#configuring" title="Chapter 5. Configuring pkgsrc">Chapter 5, <i>Configuring pkgsrc</i></a> for the details.</p>
 <p>To update pkgsrc from a tar file, download the tar file as
 	explained above. Then, make sure that you have not made any
 	changes to the files in the pkgsrc directory. Remove the pkgsrc
 	directory and extract the new tar file. Done.</p>

 <p>pkgsrc can be bootstrapped for use in two different modes:
     privileged and unprivileged one. In unprivileged mode in contrast
     to privileged one all programs are installed under one particular user
     and cannot utilise privileged operations (packages don't create
     special users and all special file permissions like setuid are ignored).
     </p>
 <p>Installing the bootstrap kit from source should be as simple as:</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>env CVS_RSH=ssh cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P pkgsrc</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>cd pkgsrc/bootstrap</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>./bootstrap</code></strong>
     </pre>
 <p>To bootstrap in unprivileged mode pass <span class="quote">&#8220;<span class="quote">--unprivileged</span>&#8221;</span> flag to <span class="command"><strong>bootstrap</strong></span></p>
 <p>By default, in privileged mode pkgsrc uses
     <code class="filename">/usr/pkg</code> for <span class="emphasis"><em>prefix</em></span>
     where programs will be installed in,
     and <code class="filename">/usr/pkg/pkgdb</code> for the package database
     directory where pkgsrc will do its internal bookkeeping,
     <code class="filename">/var</code> is used as <span class="emphasis"><em>varbase</em></span>,
     where packages install their persistent data.
     In unprivileged mode pkgsrc uses
     <code class="filename">~/pkg</code> for <span class="emphasis"><em>prefix</em></span>,
     <code class="filename">~/pkg/pkgdb</code> for the package database,
     and <code class="filename">~/pkg/var</code> for <span class="emphasis"><em>varbase</em></span>.
     </p>
 <p>You can change default layout using command-line arguments.
     Run <span class="quote">&#8220;<span class="quote">./bootstrap --help</span>&#8221;</span> to get details.
     </p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Note</h3>
 <p>The bootstrap installs a <span class="command"><strong>bmake</strong></span> tool.
       Use this <span class="command"><strong>bmake</strong></span> when building via pkgsrc.
       For examples in this guide, use <span class="command"><strong>bmake</strong></span>
       instead of <span class="quote">&#8220;<span class="quote">make</span>&#8221;</span>.</p>
 </div>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Note</h3>
 <p>It is possible to bootstrap multiple instances of pkgsrc

 </div>
 <p>Basically, there are two ways of using pkgsrc. The first
 is to only install the package tools and to use binary packages
 that someone else has prepared. This is the <span class="quote">&#8220;<span class="quote">pkg</span>&#8221;</span>
 in pkgsrc. The second way is to install the <span class="quote">&#8220;<span class="quote">src</span>&#8221;</span>
 of pkgsrc, too. Then you are able to build your own packages,
 and you can still use binary packages from someone else.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="using-pkg"></a>4.1. Using binary packages</h2></div></div></div>
 <p>On the <a class="ulink" href="ftp://ftp.NetBSD.org/" target="_top">ftp.NetBSD.org</a>
   server and its mirrors, there are collections of binary packages,
   ready to be installed. These binary packages have been built using the
   default settings for the directories, that is:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><code class="filename">/usr/pkg</code> for <code class="varname">LOCALBASE</code>, where most of the files are installed,</p></li>
 <li class="listitem"><p><code class="filename">/usr/pkg/etc</code> for configuration files,</p></li>
 <li class="listitem"><p><code class="filename">/var</code> for <code class="varname">VARBASE</code>, where those files are installed that may change after installation.</p></li>
 </ul></div>
 <p>If you cannot use these directories for whatever reasons (maybe
   because you're not root), you cannot use these binary packages, but
   have to build the packages yourself, which is explained in <a class="xref" href="#bootstrapping-pkgsrc" title="3.2. Bootstrapping pkgsrc">Section 3.2, &#8220;Bootstrapping pkgsrc&#8221;</a>.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="finding-binary-packages"></a>4.1.1. Finding binary packages</h3></div></div></div>
 <p>To install binary packages, you first need to know from where
     to get them. The first place where you should look is on the main
     pkgsrc FTP server in the directory <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/" target="_top"><code class="filename">/pub/pkgsrc/packages</code></a>.</p>
 <p>This directory contains binary packages for multiple
     platforms. First, select your operating system. (Ignore the
     directories with version numbers attached to it, they just exist for
     legacy reasons.) Then, select your hardware architecture, and in the
     third step, the OS version and the <span class="quote">&#8220;<span class="quote">version</span>&#8221;</span> of pkgsrc.</p>
 <p>In this directory, you often find a file called
     <code class="filename">bootstrap.tar.gz</code> which contains the package
     management tools. If the file is missing, it is likely that your
     operating system already provides those tools. Download the file and
     extract it in the <code class="filename">/</code> directory. It will create
     the directories <code class="filename">/usr/pkg</code> (containing the tools
     for managing binary packages and the database of installed packages).</p>
 </div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="installing-binary-packages"></a>4.1.2. Installing binary packages</h3></div></div></div>
 <p>In the directory from the last section, there is a
     subdirectory called <code class="filename">All/</code>, which contains all the
     binary packages that are available for the platform, excluding those
     that may not be distributed via FTP or CDROM (depending on which
     medium you are using).</p>
 <p>To install packages directly from an FTP or HTTP server, run
     the following commands in a Bourne-compatible shell (be sure to
     <span class="command"><strong>su</strong></span> to root first):</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>PATH="/usr/pkg/sbin:$PATH"</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>PKG_PATH="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/<em class="replaceable"><code>OPSYS</code></em>/<em class="replaceable"><code>ARCH</code></em>/<em class="replaceable"><code>VERSIONS</code></em>/All/"</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>export PATH PKG_PATH</code></strong>
 </pre>
 <p>Instead of URLs, you can also use local paths, for example if
     you are installing from a set of CDROMs, DVDs or an NFS-mounted
     repository. If you want to install packages from multiple sources,
     you can separate them by a semicolon in
     <code class="varname">PKG_PATH</code>.</p>
 <p>After these preparations, installing a package is very
     easy:</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>pkg_add libreoffice</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>pkg_add ap24-php71-*</code></strong>
 </pre>
 <p>Note that any prerequisite packages needed to run the
     package in question will be installed, too, assuming they are
     present where you install from.</p>
 <p>Adding packages might install vulnerable packages.
     Thus you should run <span class="command"><strong>pkg_admin audit</strong></span>
     regularly, especially after installing new packages, and verify
     that the vulnerabilities are acceptable for your configuration.</p>
 <p>After you've installed packages, be sure to have
     <code class="filename">/usr/pkg/bin</code> and <code class="filename">/usr/pkg/sbin</code> in your
     <code class="varname">PATH</code> so you can actually start the just
     installed program.</p>
 </div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="using.pkg_delete"></a>4.1.3. Deinstalling packages</h3></div></div></div>
 <p>To deinstall a package, it does not matter whether it was
     installed from source code or from a binary package. The
     <span class="command"><strong>pkg_delete</strong></span> command does not know it anyway.
     To delete a package, you can just run <span class="command"><strong>pkg_delete
     <em class="replaceable"><code>package-name</code></em></strong></span>. The package
     name can be given with or without version number. Wildcards can
     also be used to deinstall a set of packages, for example
     <code class="literal">*emacs*</code>. Be sure to include them in quotes,
     so that the shell does not expand them before
     <code class="literal">pkg_delete</code> sees them.</p>
 <p>The <code class="option">-r</code> option is very powerful: it
     removes all the packages that require the package in question
     and then removes the package itself. For example:
     </p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>pkg_delete -r jpeg</code></strong>
     </pre>
 <p>
     will remove jpeg and all the packages that used it; this allows
     upgrading the jpeg package.</p>

 <p>
       The NetBSD Security-Officer and Packages Groups maintain a list of
       known security vulnerabilities to packages which are (or have been)
       included in pkgsrc.  The list is available from the NetBSD
       FTP site at <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities</a>.
     </p>
 <p>
       Through <span class="command"><strong>pkg_admin fetch-pkg-vulnerabilities</strong></span>,
       this list can be downloaded
       automatically, and a security audit of all packages installed on a system
       can take place.
     </p>
 <p>
       There are two components to auditing.  The first
       step, <span class="command"><strong>pkg_admin fetch-pkg-vulnerabilities</strong></span>,
       is for downloading
       the list of vulnerabilities from the NetBSD FTP site.  The second
       step, <span class="command"><strong>pkg_admin audit</strong></span>, checks to see if any of your
       installed packages are vulnerable.  If a package is vulnerable, you
       will see output similar to the following:
     </p>
 <pre class="screen">Package samba-2.0.9 has a local-root-shell vulnerability, see
     http://www.samba.org/samba/whatsnew/macroexploit.html</pre>

       You may wish to have the
       <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities" target="_top">vulnerabilities</a>
       file downloaded daily so that
       it remains current.  This may be done by adding an appropriate entry
-      to the root users <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?crontab+5.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">crontab</span>(5)</span></a> entry.  For example the entry

 <p>After obtaining pkgsrc, the <code class="filename">pkgsrc</code>
   directory now contains a set of packages, organized into
   categories. You can browse the online index of packages, or run
   <span class="command"><strong>make readme</strong></span> from the <code class="filename">pkgsrc</code>
   directory to build local <code class="filename">README.html</code> files for

 <p>The default <span class="emphasis"><em>prefix</em></span> for installed packages
   is <code class="filename">/usr/pkg</code>. If you wish to change this, you
   should do so by setting <code class="varname">LOCALBASE</code> in

   different <code class="varname">LOCALBASE</code> definitions on the same

 <p>The rest of this chapter assumes that the package is already

 <p>To build packages from source, you need a working C
     compiler. On NetBSD, you need to install the
     <span class="quote">&#8220;<span class="quote">comp</span>&#8221;</span> and the <span class="quote">&#8220;<span class="quote">text</span>&#8221;</span> distribution
     sets. If you want to build X11-related packages, the
     <span class="quote">&#8220;<span class="quote">xbase</span>&#8221;</span> and <span class="quote">&#8220;<span class="quote">xcomp</span>&#8221;</span> distribution
     sets are required, too.</p>
 </div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="fetching-distfiles"></a>4.2.2. Fetching distfiles</h3></div></div></div>
 <p>The first step for building a package is downloading the
     distfiles (i.e. the unmodified source). If they have not yet been
     downloaded, pkgsrc will fetch them automatically.</p>
 <p>If you have all files that you need in the
     <code class="filename">distfiles</code> directory,
     you don't need to connect. If the distfiles are on CD-ROM, you can
     mount the CD-ROM on <code class="filename">/cdrom</code> and add:
     </p>
 <pre class="screen">DISTDIR=/cdrom/pkgsrc/distfiles</pre>
 <p>
     to your <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.</p>
 <p>By default a list of distribution sites will be randomly
     intermixed to prevent huge load on servers which holding popular
     packages (for example, SourceForge.net mirrors). Thus, every
     time when you need to fetch yet another distfile all the mirrors
     will be tried in new (random) order. You can turn this feature
     off by setting <code class="varname">MASTER_SORT_RANDOM=NO</code> (for
     <code class="varname">PKG_DEVELOPER</code>s it's already disabled).</p>
 <p>You can overwrite some of the major distribution sites to
     fit to sites that are close to your own.  By setting one or two
     variables you can modify the order in which the master sites are
     accessed.  <code class="varname">MASTER_SORT</code> contains a whitespace
     delimited list of domain suffixes.
     <code class="varname">MASTER_SORT_REGEX</code> is even more flexible, it
     contains a whitespace delimited list of regular expressions.  It
     has higher priority than <code class="varname">MASTER_SORT</code>.  Have a
     look at <code class="filename">pkgsrc/mk/defaults/mk.conf</code> to find
     some examples.  This may save some of your bandwidth and
     time.</p>
 <p>You can change these settings either in your shell's environment, or,
     if you want to keep the settings, by editing the
     <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> file,
     and adding the definitions there.</p>
 <p>
       If a package depends on many other packages (such as
-      <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/kde4/README.html" target="_top"><code class="filename">meta-pkgs/kde4</code></a>), the build process may
+      <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/kde4/README.html" target="_top"><code class="filename">meta-pkgs/kde4</code></a>), the build process may
       alternate between periods of
       downloading source, and compiling. To ensure you have all the source
       downloaded initially you can run the command:
       </p>
 <pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>make fetch-list | sh</code></strong></pre>
 <p>
       which will output and run a set of shell commands to fetch the
       necessary files into the <code class="filename">distfiles</code> directory.  You can
       also choose to download the files manually.

 <a name="how-to-build-and-install"></a>4.2.3. How to build and install</h3></div></div></div>
 <p>
       Once the software has downloaded, any patches will be applied, then it
       will be compiled for you. This may take some time depending on your
       computer, and how many other packages the software depends on and their
       compile time.
     </p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Note</h3>
 <p>If using bootstrap or pkgsrc on a non-NetBSD system,
     use the pkgsrc <span class="command"><strong>bmake</strong></span> command instead of
     <span class="quote">&#8220;<span class="quote">make</span>&#8221;</span> in the examples in this guide.</p>
 </div>
 <p>For example, type</p>
 <pre class="screen">
 <code class="prompt">%</code> <strong class="userinput"><code>cd misc/figlet</code></strong>
 <code class="prompt">%</code> <strong class="userinput"><code>make</code></strong>
     </pre>
 <p>at the shell prompt to build the various components of the
     package.</p>
 <p>The next stage is to actually install the newly compiled
     program onto your system. Do this by entering:
     </p>
 <pre class="screen">
 <code class="prompt">%</code> <strong class="userinput"><code>make install</code></strong>
     </pre>
 <p>
     while you are still in the directory for whatever package you
     are installing.</p>
 <p>Installing the package on your system may require you to
     be root.  However, pkgsrc has a
     <span class="emphasis"><em>just-in-time-su</em></span> feature, which allows you
     to only become root for the actual installation step.</p>
 <p>That's it, the software should now be installed and setup for use.
     You can now enter:
     </p>
 <pre class="screen">
 <code class="prompt">%</code> <strong class="userinput"><code>make clean</code></strong>
     </pre>
 <p>
     to remove the compiled files in the work directory, as you shouldn't need
     them any more. If other packages were also added to your system
     (dependencies) to allow your program to compile, you can tidy these up
     also with the command:</p>
 <pre class="screen">
 <code class="prompt">%</code> <strong class="userinput"><code>make clean-depends</code></strong>
     </pre>
 <p>Taking the figlet utility as an example, we can install it on our
     system by building as shown in <a class="xref" href="#logs" title="Appendix B. Build logs">Appendix B, <i>Build logs</i></a>.</p>
 <p>The program is installed under the default root of the
     packages tree - <code class="filename">/usr/pkg</code>. Should this not
     conform to your tastes, set the <code class="varname">LOCALBASE</code>
     variable in your environment, and it will use that value as the
     root of your packages tree. So, to use
     <code class="filename">/usr/local</code>, set
     <code class="varname">LOCALBASE=/usr/local</code> in your environment.
     Please note that you should use a directory which is dedicated to
     packages and not shared with other programs (i.e., do not try and
     use <code class="varname">LOCALBASE=/usr</code>).  Also, you should not try
     to add any of your own files or directories (such as
     <code class="filename">src/</code>, <code class="filename">obj/</code>, or
     <code class="filename">pkgsrc/</code>) below the
     <code class="varname">LOCALBASE</code> tree.  This is to prevent possible
     conflicts between programs and other files installed by the
     package system and whatever else may have been installed
     there.</p>
 <p>Some packages look in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to
     alter some configuration options at build time.  Have a look at
     <code class="filename">pkgsrc/mk/defaults/mk.conf</code> to get an overview
     of what will be set there by default.  Environment variables such
     as <code class="varname">LOCALBASE</code> can be set in
     <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to save having to remember to
     set them each time you want to use pkgsrc.</p>
 <p>Occasionally, people want to <span class="quote">&#8220;<span class="quote">look under the
     covers</span>&#8221;</span> to see what is going on when a package is building
     or being installed. This may be for debugging purposes, or out of
     simple curiosity. A number of utility values have been added to
     help with this.</p>

     server, you can use the "bin-install" target. This target will

 <p>A final word of warning: If you set up a system that has a
     non-standard setting for <code class="varname">LOCALBASE</code>, be sure to
     set that before any packages are installed, as you cannot use
     several directories for the same purpose. Doing so will result in
     pkgsrc not being able to properly detect your installed packages,
     and fail miserably. Note also that precompiled binary packages are
     usually built with the default <code class="varname">LOCALBASE</code> of
     <code class="filename">/usr/pkg</code>, and that you should
     <span class="emphasis"><em>not</em></span> install any if you use a non-standard

 <p>Some packages have build time options, usually to select
     between different dependencies, enable optional support for big
     dependencies or enable experimental features.</p>
 <p>To see which options, if any, a package supports, and which
     options are mutually exclusive, run <span class="command"><strong>make
     show-options</strong></span>, for example:</p>
 <pre class="programlisting">
     The following options are supported by this package:
         ssl      Enable SSL support.
     Exactly one of the following gecko options is required:
         firefox  Use firefox as gecko rendering engine.
         mozilla  Use mozilla as gecko rendering engine.
     At most one of the following database options may be selected:
         mysql    Enable support for MySQL database.
         pgsql    Enable support for PostgreSQL database.
     These options are enabled by default: firefox
     These options are currently enabled: mozilla ssl
 </pre>
 <p>The following variables can be defined in
     <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to select which options to
     enable for a package: <code class="varname">PKG_DEFAULT_OPTIONS</code>,
     which can be used to select or disable options for all packages
     that support them, and
     <code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code>,
     which can be used to select or disable options specifically for
     package <em class="replaceable"><code>pkgbase</code></em>.  Options listed in
     these variables are selected, options preceded by <span class="quote">&#8220;<span class="quote">-</span>&#8221;</span>
     are disabled. A few examples:</p>
 <pre class="screen">
 <code class="prompt">$</code> <span class="command"><strong>grep "PKG.*OPTION" <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a></strong></span>
 PKG_DEFAULT_OPTIONS=    -arts -dvdread -esound
 PKG_OPTIONS.kdebase=    debug -sasl
 PKG_OPTIONS.apache=     suexec </pre>
 <p>It is important to note that options that were specifically
     suggested by the package maintainer must be explicitly removed if
     you do not wish to include the option.  If you are unsure you can view
     the current state with <span class="command"><strong>make show-options</strong></span>.</p>
 <p>The following settings are consulted in the order given, and
     the last setting that selects or disables an option is
     used:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>the default options as suggested by the package
       maintainer</p></li>
 <li class="listitem"><p>the options implied by the settings of legacy
       variables (see below)</p></li>
 <li class="listitem"><p><code class="varname">PKG_DEFAULT_OPTIONS</code></p></li>
 <li class="listitem"><p><code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code></p></li>
 </ol></div>
 <p>For groups of mutually exclusive options, the last option
     selected is used, all others are automatically disabled.  If an
     option of the group is explicitly disabled, the previously
     selected option, if any, is used.  It is an error if no option
     from a required group of options is selected, and building the
     package will fail.</p>
 <p>Before the options framework was introduced, build options
     were selected by setting a variable (often named
     <code class="varname">USE_<em class="replaceable"><code>FOO</code></em></code>) in
     <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> for each option.  To ease
     transition to the options framework for the user, these legacy
     variables are converted to the appropriate options setting
     (<code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code>)
     automatically.  A warning is issued to prompt the user to update
     <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to use the options framework
     directly.  Support for the legacy variables will be removed
     eventually.</p>

 </div>
 <p>For a number of reasons you may want to build binary packages
 for a large selected set of packages in pkgsrc or even for all pkgsrc packages.
 For instance, when you have multiple machines that should run the same software,
 it is wasted time if they all build their packages themselves from source.
 Or you may want to build a list of packages you want and check them before
 deploying onto production system.
 There is a way of getting a set of binary packages:
 The bulk build system, or pbulk ("p" stands for "parallel").
 This chapter describes how to set it up.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="bulk.pre"></a>7.1. Preparations</h2></div></div></div>
 <p>First of all, you have to decide whether you build all packages
 or a limited set of them. Full bulk builds usually consume a lot more resources,
 both space and time, than builds for some practical sets of packages.
 There exists a number of particularly heavy packages that are not actually
 interesting to a wide audience.
 For a limited bulk builds you need to make a list of packages you want to build.
 Note that all their dependencies will be built, so you don't need to track them manually.
 </p>
 <p>During bulk builds various packages are installed and deinstalled
 in <code class="filename">/usr/pkg</code> (or whatever <code class="filename">LOCALBASE</code> is),
 so make sure that you don't need any package during the builds.
 Essentially, you should provide a fresh system, either a chroot environment
 or something even more restrictive, depending on what the operating system provides,
 or dedicate the whole physical machine.
 As a useful side effect this makes sure that bulk builds cannot
 break anything in your system. There have been numerous cases where
 certain packages tried to install files outside the
 <code class="filename">LOCALBASE</code> or wanted to edit some files in
 <code class="filename">/etc</code>.

 <li class="listitem"><p>First, build the pbulk infrastructure in a fresh pkgsrc location.</p></li>

 <div class="titlepage"><div><div><h3 class="title">
 <a name="bulk.pbulk.conf"></a>7.2.1. Configuration</h3></div></div></div>
 <p>To simplify configuration, we provide the helper script <code class="filename">mk/pbulk/pbulk.sh</code>.</p>
 <p>In order to use it, prepare a clear system (real one, chroot environment, jail, zone, virtual machine).
 Configure network access to fetch distribution files.
 Create a user with name "pbulk".</p>
 <p>Fetch and extract pkgsrc. Use a command like one of these:</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>(cd /usr &amp;&amp; ftp -o - http://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz | tar -zxf-)</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>(cd /usr &amp;&amp; fetch -o - http://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz | tar -zxf-)</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>(cd /usr &amp;&amp; cvs -Q -z3 -d anoncvs@anoncvs.NetBSD.org:/cvsroot get -P pkgsrc)</code></strong>
 </pre>
 <p>Or any other way that fits (e.g., curl, wget).</p>
 <p>Deploy and configure pbulk tools, e.g.:</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>sh pbulk.sh -n # use native make, no bootstrap kit needed (for use on NetBSD)</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>sh pbulk.sh -n -c mk.conf.frag # native, apply settings from given mk.conf fragment</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>sh pbulk.sh -nlc mk.conf.frag # native, apply settings, configure for limited build</code></strong>
 </pre>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Note</h3>
 <p><code class="filename">mk.conf.frag</code> is a fragment of
 <code class="filename">mk.conf</code> that contains settings you want to

 <pre class="programlisting">

 X11_TYPE=               modular # use pkgsrc X11

 </pre>
 </div>
 <p>If configured for limited list, replace the list in <code class="filename">/usr/pbulk/etc/pbulk.list</code>
 with your list of packages, one per line without empty lines or comments. E.g.:</p>
 <pre class="programlisting">
 www/firefox
 mail/thunderbird
 misc/libreoffice4
 </pre>
 <p>At this point you can also review configuration in <code class="filename">/usr/pbulk/etc</code>
 and make final amendments, if wanted.</p>
 <p>Start it:</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>/usr/pbulk/bin/bulkbuild</code></strong>
 </pre>
 <p>After it finishes, you'll have <code class="filename">/mnt</code> filled with distribution files, binary packages, and reports,

 <p>After your pkgsrc bulk-build has completed, you may wish to
     create a CD-ROM set of the resulting binary packages to assist

     a simple tool for creating the ISO 9660 images.
     <span class="command"><strong>cdpack</strong></span> arranges the packages on the CD-ROMs in a
     way that keeps all the dependencies for a given package on the same
     CD as that package.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="cdpack-example"></a>7.4.1. Example of cdpack</h3></div></div></div>
 <p>Complete documentation for cdpack is found in the cdpack(1)
       man page. The following short example assumes that the binary
       packages are left in
       <code class="filename">/usr/pkgsrc/packages/All</code> and that
       sufficient disk space exists in <code class="filename">/u2</code> to
       hold the ISO 9660 images.</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>mkdir /u2/images</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>pkg_add /usr/pkgsrc/packages/All/cdpack</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>cdpack /usr/pkgsrc/packages/All /u2/images</code></strong>
       </pre>
 <p>If you wish to include a common set of files
       (<code class="filename">COPYRIGHT</code>, <code class="filename">README</code>,
       etc.) on each CD in the collection, then you need to create a
       directory which contains these files. e.g.</p>
 <pre class="screen">
 <code class="prompt">#</code> <strong class="userinput"><code>mkdir /tmp/common</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>echo "This is a README" &gt; /tmp/common/README</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>echo "Another file" &gt; /tmp/common/COPYING</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>mkdir /tmp/common/bin</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>echo "#!/bin/sh" &gt; /tmp/common/bin/myscript</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>echo "echo Hello world" &gt;&gt; /tmp/common/bin/myscript</code></strong>
 <code class="prompt">#</code> <strong class="userinput"><code>chmod 755 /tmp/common/bin/myscript</code></strong>
       </pre>
 <p>Now create the images:</p>
 <pre class="screen"><code class="prompt">#</code> <strong class="userinput"><code>cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images</code></strong></pre>
 <p>Each image will contain <code class="filename">README</code>,
       <code class="filename">COPYING</code>, and <code class="filename">bin/myscript</code>
       in their root directories.</p>

 <p>The files that are installed by pkgsrc are organized in a way that
 is similar to what you find in the <code class="filename">/usr</code> directory
 of the base system. But some details are different. This is because
 pkgsrc initially came from FreeBSD and had adopted its file system
 hierarchy. Later it was largely influenced by NetBSD. But no matter
 which operating system you are using pkgsrc with, you can expect the
 same layout for pkgsrc.</p>
 <p>There are mainly four root directories for pkgsrc, which are all
 configurable in the <code class="filename">bootstrap/bootstrap</code> script.
 When pkgsrc has been installed as root, the default locations
 are:</p>
 <pre class="programlisting">
 LOCALBASE=              /usr/pkg
 PKG_SYSCONFBASE=        /usr/pkg/etc
 VARBASE=                /var
 PKG_DBDIR=              /usr/pkg/pkgdb
 </pre>
 <p>In unprivileged mode (when pkgsrc has been installed as any other
 user), the default locations are:</p>
 <pre class="programlisting">
 LOCALBASE=              ${HOME}/pkg
 PKG_SYSCONFBASE=        ${HOME}/pkg/etc
 VARBASE=                ${HOME}/pkg/var
 PKG_DBDIR=              ${HOME}/pkg/pkgdb
 </pre>
 <p>What these four directories are for, and what they look like is
 explained below.</p>

 <code class="varname">PKG_RESUME_TRANSFERS=YES</code> into
 <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.  If, during a fetch step, an incomplete

 <p>You can also
 use a different program than the platform default program by changing the

 using of ftp, fetch, wget or curl.  Alternatively, fetching can be disabled
 by using the value manual.  A value of custom disables the system defaults

 provide <code class="varname">FETCH_CMD</code>, <code class="varname">FETCH_BEFORE_ARGS</code>,

 <p>As the system administrator, you can choose where configuration files
 are installed.  The default settings make all these files go into
 <code class="filename">${PREFIX}/etc</code> or some of its subdirectories; this may
 be suboptimal depending on your expectations (e.g., a read-only,
 NFS-exported <code class="varname">PREFIX</code> with a need of per-machine

 <p>In order to change the defaults, you can modify the
 <code class="varname">PKG_SYSCONFBASE</code> variable (in

 directory; some common examples include <code class="filename">/etc</code> or
 <code class="filename">/etc/pkg</code>.</p>
 <p>Furthermore, you can change this value on a per-package basis by
 setting the <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> variable.
 <code class="varname">PKG_SYSCONFVAR</code>'s value usually matches the name of the
 package you would like to modify, that is, the contents of

 </div>
 <p>When you find a package that is not yet in pkgsrc, you
 most likely have a URL from where you can download the source
 code. Starting with this URL, creating a package involves only a
 few steps.</p>
 <div class="procedure"><ol class="procedure" type="1">
-<li class="step"><p>First, install the packages <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/url2pkg/README.html" target="_top"><code class="filename">pkgtools/url2pkg</code></a> and <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkglint/README.html" target="_top"><code class="filename">pkgtools/pkglint</code></a>.</p></li>
+<li class="step"><p>First, install the packages <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/url2pkg/README.html" target="_top"><code class="filename">pkgtools/url2pkg</code></a> and <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkglint/README.html" target="_top"><code class="filename">pkgtools/pkglint</code></a>.</p></li>
 <li class="step"><p>Then, choose one of the top-level directories as the
 category in which you want to place your package. You can also create a
 directory of your own (maybe called <code class="filename">local</code>). In that
 category directory, create another directory for your package and change
 into it.</p></li>
 <li class="step"><p>Run the program <span class="command"><strong>url2pkg</strong></span>, which will ask
 you for a URL. Enter the URL of the distribution file (in most cases a
 <code class="filename">.tar.gz</code> file) and watch how the basic ingredients
 of your package are created automatically. The distribution file is
 extracted automatically to fill in some details in the
 <code class="filename">Makefile</code> that would otherwise have to be done
 manually.</p></li>
 <li class="step">
 <p>Examine the extracted files to determine the dependencies of
 your package. Ideally, this is mentioned in some
 <code class="filename">README</code> file, but things may differ. For each of
 these dependencies, look where it exists in pkgsrc, and if there is a
 file called <code class="filename">buildlink3.mk</code> in that directory, add a
 line to your package <code class="filename">Makefile</code> which includes that
 file just before the last line. If the
 <code class="filename">buildlink3.mk</code> file does not exist, it must be
 created first. The <code class="filename">buildlink3.mk</code> file makes sure that the package's include files and libraries are provided.</p>
 <p>If you just need binaries from a package, add a
 <code class="varname">DEPENDS</code> line to the Makefile, which specifies the
 version of the dependency and where it can be found in pkgsrc. This line
 should be placed in the third paragraph. If the dependency is only
 needed for building the package, but not when using it, use
 <code class="varname">BUILD_DEPENDS</code> instead of <code class="varname">DEPENDS</code>.
 Your package may then look like this:</p>
 <pre class="programlisting">
 [...]
 BUILD_DEPENDS+= libxslt-[0-9]*:../../textproc/libxslt
 DEPENDS+=       screen-[0-9]*:../../misc/screen
 DEPENDS+=       screen&gt;=4.0:../../misc/screen
 [...]
 .include "../../<em class="replaceable"><code>category</code></em>/<em class="replaceable"><code>package</code></em>/buildlink3.mk"
 .include "../../devel/glib2/buildlink3.mk"
 .include "../../mk/bsd.pkg.mk"
 </pre>
 </li>
 <li class="step"><p>Run <span class="command"><strong>pkglint</strong></span> to see what things still need
 to be done to make your package a <span class="quote">&#8220;<span class="quote">good</span>&#8221;</span> one. If you don't
 know what pkglint's warnings want to tell you, try <span class="command"><strong>pkglint
 --explain</strong></span> or <span class="command"><strong>pkglint
 -e</strong></span>, which outputs additional
 explanations.</p></li>
 <li class="step"><p>In many cases the package is not yet ready to build. You can
 find instructions for the most common cases in the next section, <a class="xref" href="#creating.common" title="10.1. Common types of packages">Section 10.1, &#8220;Common types of packages&#8221;</a>. After you have followed the instructions
 over there, you can hopefully continue here.</p></li>
 <li class="step"><p>Run <span class="command"><strong>bmake clean</strong></span> to clean the working
 directory from the extracted files. Besides these files, a lot of cache

 <a name="creating.python-module"></a>10.1.2. Python modules and programs</h3></div></div></div>
 <p>Python modules and programs packages are easily created using a
 set of predefined variables.</p>
 <p>
 If some Python versions are not supported by the software, set the
 <code class="varname">PYTHON_VERSIONS_INCOMPATIBLE</code> variable to the Python versions
 that are not supported, e.g.
 </p>
 <pre class="programlisting">
 PYTHON_VERSIONS_INCOMPATIBLE=       27
 </pre>
 <p>
 If the packaged software is a Python module, include one of
 <code class="filename">../../lang/python/egg.mk</code>,
 <code class="filename">../../lang/python/distutils.mk</code>, or
 <code class="filename">../../lang/python/extension.mk</code>.</p>
 <p>Most Python packages use either <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> or
 easy-setup/setuptools (<span class="quote">&#8220;<span class="quote">eggs</span>&#8221;</span>).
 if the packaged software is using setuptools, you only need
 to include <span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/egg.mk</code></span>&#8221;</span>.
 Otherwise, if the software uses <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span>, include
 <span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/distutils.mk</code></span>&#8221;</span>.
 so pkgsrc will use this framework.
 <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> uses a script called <code class="filename">setup.py</code>,
 if the <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> driver is not called
 <code class="filename">setup.py</code>, set the <code class="varname">PYSETUP</code> variable
 to the name of the script.</p>
 <p>Either way, the package directory should be called
 <span class="quote">&#8220;<span class="quote">py-software</span>&#8221;</span> and <code class="varname">PKGNAME</code> should be set to
 <span class="quote">&#8220;<span class="quote">${PYPKGPREFIX}-${DISTNAME}</span>&#8221;</span>, e.g.
 </p>
 <pre class="programlisting">
 DISTNAME=   foopymodule-1.2.10
 PKGNAME=    ${PYPKGPREFIX}-${DISTNAME}
 </pre>
 <p>If it is an application, include
 <span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/application.mk</code></span>&#8221;</span>.
 In order to correctly set the path to the Python interpreter, use the
 <code class="varname">REPLACE_PYTHON</code> variable and set it to the list of files
 (paths relative to <code class="varname">WRKSRC</code>) that must be corrected.
 For example:
 </p>
 <pre class="programlisting">
 REPLACE_PYTHON=   *.py
 </pre>
 <p>Some Python modules have separate distributions for Python-2.x
 and Python-3.x support. In pkgsrc this is handled by the
 <code class="filename">versioned_dependencies.mk</code> file. Set
 <code class="varname">PYTHON_VERSIONED_DEPENDENCIES</code> to the list of
 packages that should be depended upon and include
 <span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/versioned_dependencies.mk</code></span>&#8221;</span>,
 then the pkgsrc infrastructure will depend on the appropriate package
 version. For example:
 </p>
 <pre class="programlisting">
 PYTHON_VERSIONED_DEPENDENCIES=dialog
 </pre>
 <p>
 Look inside <code class="filename">versioned_dependencies.mk</code> for a list
 of supported packages.</p>

 <p>Looking at the file <code class="filename">pkgsrc/doc/TODO</code>, I saw
 that the <span class="quote">&#8220;<span class="quote">nvu</span>&#8221;</span> package has not yet been imported into
 pkgsrc. As the description says it has to do with the web, the obvious
 choice for the category is <span class="quote">&#8220;<span class="quote">www</span>&#8221;</span>.</p>
 <pre class="programlisting">
 <code class="prompt">$</code> mkdir www/nvu
 <code class="prompt">$</code> cd www/nvu
 </pre>
 <p>The web site says that the sources are available as a tar file, so
 I fed that URL to the <span class="command"><strong>url2pkg</strong></span> program:</p>
 <pre class="programlisting">
 <code class="prompt">$</code> url2pkg http://cvs.nvu.com/download/nvu-1.0-sources.tar.bz2
 </pre>
 <p>My editor popped up, and I added a <code class="varname">PKGNAME</code> line
 below the <code class="varname">DISTNAME</code> line, as the package name should
 not have the word <span class="quote">&#8220;<span class="quote">sources</span>&#8221;</span> in it. I also filled in the
 <code class="varname">MAINTAINER</code>, <code class="varname">HOMEPAGE</code> and
 <code class="varname">COMMENT</code> fields. Then the package
 <code class="filename">Makefile</code> looked like that:</p>
 <pre class="programlisting">

 <p>On the first line of output above, an artificial space has been added between NetBSD and $,
 this is a workaround to prevent CVS expanding to the filename of the

 <p>Now that the package has been extracted, let's see what's inside
 it. The package has a <code class="filename">README.txt</code>, but that only
 says something about mozilla, so it's probably useless for seeing what
 dependencies this package has. But since there is a GNU configure script
 in the package, let's hope that it will complain about everything it
 needs.</p>
 <pre class="programlisting">
 <code class="prompt">$</code> bmake

 </pre>
 <p>That worked quite well. So I opened the package Makefile in my
 editor, and since it already has a <code class="varname">USE_TOOLS</code> line, I
 just appended <span class="quote">&#8220;<span class="quote">perl</span>&#8221;</span> to it. Since the dependencies of the
 package have changed now, and since a perl wrapper is automatically
 installed in the <span class="quote">&#8220;<span class="quote">tools</span>&#8221;</span> phase, I need to build the package
 from scratch.</p>
 <pre class="programlisting">

 </pre>
 <p>So I added <span class="quote">&#8220;<span class="quote">gmake</span>&#8221;</span> to the
 <code class="varname">USE_TOOLS</code> line and tried again (from scratch).</p>
 <pre class="programlisting">

 </pre>
 <p>Now to the other dependencies. The first question is: Where is the
 GTK package hidden in pkgsrc?</p>
 <pre class="programlisting">
 <code class="prompt">$</code> echo ../../*/gtk*
 [many packages ...]
 <code class="prompt">$</code> echo ../../*/gtk
 ../../x11/gtk
 <code class="prompt">$</code> echo ../../*/gtk2
 ../../x11/gtk2
 <code class="prompt">$</code> echo ../../*/gtk2/bui*
 ../../x11/gtk2/buildlink3.mk
 </pre>
 <p>The first try was definitely too broad. The second one had exactly
 one result, which is very good. But there is one pitfall with GNOME
 packages. Before GNOME 2 had been released, there were already many
 GNOME 1 packages in pkgsrc. To be able to continue to use these
 packages, the GNOME 2 packages were imported as separate packages, and
 their names usually have a <span class="quote">&#8220;<span class="quote">2</span>&#8221;</span> appended. So I checked
 whether this was the case here, and indeed it was.</p>
 <p>Since the GTK2 package has a <code class="filename">buildlink3.mk</code>
 file, adding the dependency is very easy. I just inserted an
 <code class="literal">.include</code> line before the last line of the package
 <code class="filename">Makefile</code>, so that it now looks like this:</p>
 <pre class="programlisting">
 [...]
 .include "../../x11/gtk2/buildlink3.mk"
 .include "../../mk/bsd.pkg.mk
 </pre>
 <p>After another <span class="command"><strong>bmake clean &amp;&amp; bmake</strong></span>, the answer
 was:</p>
 <pre class="programlisting">
 [...]
 checking for gtk-config... /home/roland/pkg/bin/gtk-config
 checking for GTK - version &gt;= 1.2.0... no
 *** Could not run GTK test program, checking why...
 *** The test program failed to compile or link. See the file config.log for the
 *** exact error that occured. This usually means GTK was incorrectly installed
 *** or that you have moved GTK since it was installed. In the latter case, you
 *** may want to edit the gtk-config script: /home/roland/pkg/bin/gtk-config
 configure: error: Test for GTK failed.
 [...]
 </pre>
 <p>In this particular case, the assumption that <span class="quote">&#8220;<span class="quote">every package
 prefers GNOME 2</span>&#8221;</span> had been wrong. The first of the lines above
 told me that this package really wanted to have the GNOME 1 version of
 GTK. If the package had looked for GTK2, it would have looked for
 <span class="command"><strong>pkg-config</strong></span> instead of <span class="command"><strong>gtk-config</strong></span>.
 So I changed the <code class="literal">x11/gtk2</code> to
 <code class="literal">x11/gtk</code> in the package <code class="filename">Makefile</code>,
 and tried again.</p>
 <pre class="programlisting">
 [...]

 In file included from xpidl.c:42:
 xpidl.h:132: error: parse error before "IDL_ns"
 [...]
 </pre>
 <p>The package still does not find all of its dependencies. Now the
 question is: Which package provides the
 <code class="filename">libIDL/IDL.h</code> header file?</p>
 <pre class="programlisting">
 <code class="prompt">$</code> echo ../../*/*idl*
 ../../devel/py-idle ../../wip/idled ../../x11/acidlaunch
 <code class="prompt">$</code> echo ../../*/*IDL*
 ../../net/libIDL
 </pre>
 <p>Let's take the one from the second try. So I included the
 <code class="filename">../../net/libIDL/buildlink3.mk</code> file and tried
 again. But the error didn't change. After digging through some of the
 code, I concluded that the build process of the package was broken and
 couldn't have ever worked, but since the Mozilla source tree is quite
 large, I didn't want to fix it. So I added the following to the package
 <code class="filename">Makefile</code> and tried again:</p>
 <pre class="programlisting">
 CPPFLAGS+=              -I${BUILDLINK_PREFIX.libIDL}/include/libIDL-2.0
 BUILDLINK_TRANSFORM+=   -l:IDL:IDL-2
 </pre>
 <p>The latter line is needed because the package expects the library
 <code class="filename">libIDL.so</code>, but only
 <code class="filename">libIDL-2.so</code> is available. So I told the compiler
 wrapper to rewrite that on the fly.</p>
 <p>The next problem was related to a recent change of the FreeType
-interface. I looked up in <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/seamonkey/README.html" target="_top"><code class="filename">www/seamonkey</code></a>
+interface. I looked up in <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/seamonkey/README.html" target="_top"><code class="filename">www/seamonkey</code></a>
 which patch files were relevant for this issue and copied them to the
 <code class="filename">patches</code> directory. Then I retried, fixed the
 patches so that they applied cleanly and retried again. This time,
 everything worked.</p>

 <p>In the first section there are the following variables, which

 <p>The name of the working directory created by pkgsrc is
       taken from the <code class="varname">WRKDIR_BASENAME</code>

       <code class="filename">work</code>. If you want to use the same

       you can change the variable according to your needs. Two
       other variables handle common cases of setting
       <code class="varname">WRKDIR_BASENAME</code> individually. If
       <code class="varname">OBJHOSTNAME</code> is defined in
       <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, the first component of
       the host's name is attached to the directory name. If
       <code class="varname">OBJMACHINE</code> is defined, the platform name
       is attached, which might look like

   a security hole. To provide maximum security, all distfiles are
   protected using three different message digest algorithms (SHA1,
   RMD160, SHA512), as well as the file size.</p>
 <p>The <code class="filename">distinfo</code> file also contains the

 <p>Some packages don't work out-of-the box on the various
   platforms that are supported by pkgsrc. These packages need
   to be patched to make them work. The patch files can be
   found in the <code class="filename">patches/</code> directory.</p>
 <p>In the <span class="emphasis"><em>patch</em></span> phase, these patches are
   applied to the files in <code class="varname">WRKSRC</code> directory after
   extracting them, in alphabetic order.</p>

 <a name="components.patch.structure"></a>11.3.1. Structure of a single patch file</h3></div></div></div>
 <p>The <code class="filename">patch-*</code> files should be in
   <span class="command"><strong>diff -bu</strong></span> format, and apply without a fuzz to avoid
   problems. (To force patches to apply with fuzz you can set
   <code class="varname">PATCH_FUZZ_FACTOR=-F2</code>). Furthermore, each patch
   should contain only changes for a single file, and no file should be
   patched by more than one patch file. This helps to keep future
   modifications simple.</p>
 <p>Each patch file is structured as follows: In the first line,
   there is the RCS Id of the patch itself. The second line should be
   empty for aesthetic reasons. After that, there should be a comment for
   each change that the patch does. There are a number of standard
   cases:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>Patches for commonly known vulnerabilities should
   mention the vulnerability ID (CAN, CVE).</p></li>
 <li class="listitem"><p>Patches that change source code should mention the
   platform and other environment (for example, the compiler) that the
   patch is needed for.</p></li>
 </ul></div>
 <p>The patch should be commented so that any
   developer who knows the code of the application can make some use of
   the patch. Special care should be taken for the upstream developers,
   since we generally want that they accept our patches, so we have less
   work in the future.</p>

 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="components.patches.caveats"></a>11.3.2. Creating patch files</h3></div></div></div>
 <p>One important thing to mention is to pay attention that no RCS
   IDs get stored in the patch files, as these will cause problems when
   later checked into the NetBSD CVS tree. Use the
-  <span class="command"><strong>pkgdiff</strong></span> command from the <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkgdiff/README.html" target="_top"><code class="filename">pkgtools/pkgdiff</code></a> package to avoid these
+  <span class="command"><strong>pkgdiff</strong></span> command from the <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkgdiff/README.html" target="_top"><code class="filename">pkgtools/pkgdiff</code></a> package to avoid these
   problems.</p>
 <p>For even more automation, we recommend using
   <span class="command"><strong>mkpatches</strong></span> from the same package to make a
   whole set of patches. You just have to backup files before you
   edit them to <code class="filename">filename.orig</code>, e.g. with
   <span class="command"><strong>cp -p filename filename.orig</strong></span> or, easier, by
   using <span class="command"><strong>pkgvi</strong></span> again from the same package. If
   you upgrade a package this way, you can easily compare the new
   set of patches with the previously existing one with
   <span class="command"><strong>patchdiff</strong></span>. The files in <code class="filename">patches</code>
   are replaced by new files, so carefully check if you want to take all
   the changes.</p>
 <p>When you have finished a package, remember to generate
   the checksums for the patch files by using the <span class="command"><strong>make
   makepatchsum</strong></span> command, see <a class="xref" href="#components.distinfo" title="11.2. distinfo">Section 11.2, &#8220;<code class="filename">distinfo</code>&#8221;</a>.</p>
 <p>When adding a patch that corrects a problem in the
   distfile (rather than e.g. enforcing pkgsrc's view of where
   man pages should go), send the patch as a bug report to the
   maintainer.  This benefits non-pkgsrc users of the package,
   and usually makes it possible to remove the patch in future
   version.</p>
 <p>The file names of the patch files are usually of the form
   <code class="filename">patch-<em class="replaceable"><code>path_to_file__with__underscores.c</code></em></code>.
   Many packages still use the previous convention
   <code class="filename">patch-<em class="replaceable"><code>[a-z][a-z]</code></em></code>,
   but new patches should be of the form containing the filename.

 <div class="titlepage"><div><div><h3 class="title">
 <a name="components.patches.sources"></a>11.3.3. Sources where the patch files come from</h3></div></div></div>
 <p>If you want to share patches between multiple packages
   in pkgsrc, e.g. because they use the same distfiles, set
   <code class="varname">PATCHDIR</code> to the path where the patch files
   can be found, e.g.:</p>
 <pre class="programlisting">
 PATCHDIR= ${.CURDIR}/../xemacs/patches
 </pre>
 <p>Patch files that are distributed by the author or other
     maintainers can be listed in
     <code class="varname">PATCHFILES</code>.</p>
 <p>If it is desired to store any patches that should not be
     committed into pkgsrc, they can be kept outside the pkgsrc
     tree in the <code class="filename">$LOCALPATCHES</code> directory. The
     directory tree there is expected to have the same
     <span class="quote">&#8220;<span class="quote">category/package</span>&#8221;</span> structure as pkgsrc, and
     patches are expected to be stored inside these dirs (also
     known as <code class="filename">$LOCALPATCHES/$PKGPATH</code>). For
     example, if you want to keep a private patch for
     <code class="filename">pkgsrc/graphics/png</code>, keep it in
     <code class="filename">$LOCALPATCHES/graphics/png/mypatch</code>. All
     files in the named directory are expected to be patch files,
     and <span class="emphasis"><em>they are applied after pkgsrc patches are
     applied</em></span>.</p>

 <a name="components.patches.guidelines"></a>11.3.4. Patching guidelines</h3></div></div></div>
 <p>When fixing a portability issue in the code do not use
       preprocessor magic to check for the current operating system nor
       platform.  Doing so hurts portability to other platforms because
       the OS-specific details are not abstracted appropriately.</p>
 <p>The general rule to follow is: instead of checking for the
       operating system the application is being built on, check for the
       specific <span class="emphasis"><em>features</em></span> you need.  For example,
       instead of assuming that kqueue is available under NetBSD and
       using the <code class="varname">__NetBSD__</code> macro to conditionalize
       kqueue support, add a check that detects kqueue itself &mdash;
       yes, this generally involves patching the
       <span class="command"><strong>configure</strong></span> script.  There is absolutely nothing
       that prevents some OSes from adopting interfaces from other OSes
       (e.g. Linux implementing kqueue), something that the above checks
       cannot take into account.</p>
 <p>Of course, checking for features generally involves more
       work on the developer's side, but the resulting changes are
       cleaner and there are chances they will work on many other
       platforms.  Not to mention that there are higher chances of being
       later integrated into the mainstream sources.  Remember:
       <span class="emphasis"><em>It doesn't work unless it is right!</em></span></p>

 <p>Always, always, <span class="strong"><strong>always</strong></span>
       feed back any <span class="emphasis"><em>portability fixes</em></span> or
       improvements you do to a package to the mainstream developers.
       This is the only way to get their attention on portability issues
       and to ensure that future versions can be built out-of-the box on
       NetBSD.  Furthermore, any user that gets newer distfiles will get
       the fixes straight from the packaged code.</p>
 <p>This generally involves cleaning up the patches
       (because sometimes the patches that are
       added to pkgsrc are quick hacks), filing bug reports in the
       appropriate trackers for the projects and working with the
       mainstream authors to accept your changes.  It is
       <span class="emphasis"><em>extremely important</em></span> that you do it so that
       the packages in pkgsrc are kept simple and thus further changes
       can be done without much hassle.</p>

 <p>Pkgsrc consists of many <code class="filename">Makefile</code> fragments,

   like pkgsrc requires some discipline to keep the code correct and
   understandable.</p>
 <p>The basic ingredients for <code class="filename">Makefile</code>
   programming are variables (which are actually macros) and shell
   commands. Among these shell commands may even be more complex ones
-  like <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?awk+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">awk</span>(1)</span></a> programs. To make sure that every shell command runs

   as intended it is necessary to quote all variables correctly when they
   are used.</p>
 <p>This chapter describes some patterns, that appear quite often in
   <code class="filename">Makefile</code>s, including the pitfalls that come along

     regenerated properly. Example:</p>
 <pre class="programlisting">
 wrong:
         @echo "line 1" &gt; ${.TARGET}
         @echo "line 2" &gt;&gt; ${.TARGET}

 <a name="makefile.variables"></a>12.2. <code class="filename">Makefile</code> variables</h2></div></div></div>
 <p><code class="filename">Makefile</code> variables contain strings that
     can be processed using the five operators ``='', ``+='', ``?='',
-    ``:='', and ``!='', which are described in the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> man

     page.</p>
 <p>When a variable's value is parsed from a
     <code class="filename">Makefile</code>, the hash character ``#'' and the
     backslash character ``\'' are handled specially. If a backslash is
     followed by a newline, any whitespace immediately in front of the
     backslash, the backslash, the newline, and any whitespace
     immediately behind the newline are replaced with a single space. A
     backslash character and an immediately following hash character are
     replaced with a single hash character. Otherwise, the backslash is
     passed as is. In a variable assignment, any hash character that is
     not preceded by a backslash starts a comment that continues upto the
     end of the logical line.</p>
 <p>The evaluation of variables either happens immediately or lazy.
     It happens immediately when the variable occurs
     on the right-hand side of the ``:='' or the ``!='' operator, in a
     <code class="varname">.if</code> condition or a <code class="varname">.for</code> loop.
     In the other cases, it is evaluated lazily.</p>
 <p>Some of the modifiers split the string into words and then
     operate on the words, others operate on the string as a whole. When
-    a string is split into words, it is split like in <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?sh+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">sh</span>(1)</span></a>.</p>

 a list (example 1), it must be quoted using the <code class="code">:Q</code>
 modifier.</p>
 <p>When adding another list to a list (example 2), it must not be

 <p>Example 1 leads to a syntax error in the shell, as the characters

 <p>Example 2 quotes the string so that the shell interprets it

 <p>When passing <code class="varname">CFLAGS</code> or similar variables to a
 GNU-style configure script (especially those that call other configure
 scripts), it must not have leading or trailing whitespace, since
 otherwise the configure script gets confused. To trim leading and
 trailing whitespace, use the <code class="code">:M</code> modifier, as in the
 following example:</p>
 <pre class="programlisting">

         echo x${CPPFLAGS:Q}x            # leading and trailing whitespace
         echo x${CONFIGURE_ARGS:Q}x      # properly trimmed
 </pre>
 <p>In this example, <code class="varname">CPPFLAGS</code> has both leading and
 trailing whitespace because the <code class="code">+=</code> operator always adds a
 space.</p>

 <div class="titlepage"><div><div><h3 class="title">
 <a name="empty-variables"></a>12.3.4. Handling possibly empty variables</h3></div></div></div>
 <p>When a possibly empty variable is used in a shell program, it may

 <pre class="programlisting">
 EGFILES=        # empty

 <p>The shell only sees the text <code class="code">for egfile in ; do</code>, since
-<code class="code">${EGFILES}</code> is replaced with an empty string by <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>.

 To fix this syntax error, use one of the snippets below.</p>
 <pre class="programlisting">
 EMPTY=          # empty
 install-examples:
         for egfile in ${EGFILES} ""; do         \

                 echo "Installing $$egfile";     \
         done
 </pre>
 <p>In this case, an empty string is appended to the iteration list (to
 prevent the syntax error) and filtered out later.</p>
 <pre class="programlisting">
 EGFILES=        # empty
 install-examples:
 .for egfile in ${EGFILES}
         echo "Installing ${egfile}"
 .endfor
 </pre>
 <p>This variant only works when <code class="varname">EGFILES</code> does not
 contain filenames with spaces, since the <code class="code">.for</code> loop splits on
 simple whitespace.</p>
 <p>To have a shell command test whether a make variable is empty, use
 the following code: <code class="code">${TEST} -z ${POSSIBLY_EMPTY:Q}""</code>.</p>

 <p>You can use the <span class="command"><strong>make print-PLIST</strong></span> command
     to output a PLIST that matches any new files since the package
     was extracted.  See <a class="xref" href="#build.helpful-targets" title="17.17. Other helpful targets">Section 17.17, &#8220;Other helpful targets&#8221;</a> for

 <p>The <code class="varname">PRINT_PLIST_AWK</code> variable takes a set

     print-PLIST.  You can <span class="emphasis"><em>append</em></span> any chunk of AWK
     scripting you like to it, but be careful with quoting.</p>
 <p>For example, to get all files inside the

 <a name="plist.misc"></a>13.4. Variable substitution in PLIST</h2></div></div></div>
 <p>A number of variables are substituted automatically in
     PLISTs when a package is installed on a system. This includes the
     following variables:</p>
 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term"><code class="varname">${MACHINE_ARCH}</code>, <code class="varname">${MACHINE_GNU_ARCH}</code></span></dt>
 <dd>
 <p>Some packages like emacs and perl embed information
 	  about which architecture they were built on into the
 	  pathnames where they install their files. To handle this
 	  case, PLIST will be preprocessed before actually used, and
 	  the symbol
 	  <span class="quote">&#8220;<span class="quote"><code class="varname">${MACHINE_ARCH}</code></span>&#8221;</span> will be
 	  replaced by what <span class="command"><strong>uname -p</strong></span> gives. The
 	  same is done if the string
 	  <code class="varname">${MACHINE_GNU_ARCH}</code> is embedded in
 	  PLIST somewhere - use this on packages that have GNU
 	  autoconf-created configure scripts.</p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Legacy note</h3>
 <p>There used to be a symbol
 	    <span class="quote">&#8220;<span class="quote"><code class="varname">$ARCH</code></span>&#8221;</span> that
 	    was replaced by the output of <span class="command"><strong>uname
 	    -m</strong></span>, but that's no longer supported and has
 	    been removed.</p>
 </div>
 </dd>
 <dt><span class="term"><code class="varname">${OPSYS}</code>, <code class="varname">${LOWER_OPSYS}</code>, <code class="varname">${OS_VERSION}</code></span></dt>
 <dd>
 <p>Some packages want to embed the OS name and version
 	  into some paths.  To do this, use these variables in the
 	  <code class="filename">PLIST</code>:
 	  </p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><code class="varname">${OPSYS}</code> - output of <span class="quote">&#8220;<span class="quote"><span class="command"><strong>uname -s</strong></span></span>&#8221;</span></p></li>
 <li class="listitem"><p><code class="varname">${LOWER_OPSYS}</code> - lowercase common name (eg. <span class="quote">&#8220;<span class="quote">solaris</span>&#8221;</span>)</p></li>

 </ul></div>
 </dd>
 </dl></div>
 <p>For a list of values which are replaced by
     default, the output of <span class="command"><strong>make help topic=PLIST_SUBST</strong></span> as
 well as searching the <code class="filename">pkgsrc/mk</code> directory with <span class="command"><strong>grep</strong></span> for
 <code class="varname">PLIST_SUBST</code> should help.</p>
 <p>If you want to change other variables not listed above, you
     can add variables and their expansions to this variable in the
     following way, similar to <code class="varname">MESSAGE_SUBST</code> (see <a class="xref" href="#components.optional" title="11.5. Optional files">Section 11.5, &#8220;Optional files&#8221;</a>):</p>
 <pre class="programlisting">
 PLIST_SUBST+=   SOMEVAR="somevalue"
 </pre>
 <p>This replaces all occurrences of <span class="quote">&#8220;<span class="quote">${SOMEVAR}</span>&#8221;</span>
     in the <code class="filename">PLIST</code> with
     <span class="quote">&#8220;<span class="quote">somevalue</span>&#8221;</span>.</p>
 <p>The <code class="varname">PLIST_VARS</code> variable can be used to simplify
     the common case of conditionally including some
     <code class="filename">PLIST</code> entries. It can be done by adding
     <code class="literal"><code class="varname">PLIST_VARS</code>+=foo</code> and
     setting the corresponding <code class="varname">PLIST.foo</code> variable
     to <code class="literal">yes</code> if the entry should be included.
     This will substitute <span class="quote">&#8220;<span class="quote"><code class="varname">${PLIST.foo}</code></span>&#8221;</span>
     in the <code class="filename">PLIST</code> with either
     <span class="quote">&#8220;<span class="quote"><code class="literal">""</code></span>&#8221;</span> or
     <span class="quote">&#8220;<span class="quote"><code class="literal">"@comment "</code></span>&#8221;</span>.
     For example, in <code class="filename">Makefile</code>:</p>
 <pre class="programlisting">
 PLIST_VARS+=    foo
 .if <em class="replaceable"><code>condition</code></em>
 PLIST.foo=      yes
 .else

 <pre class="programlisting">

 <p>Buildlink is a framework in pkgsrc that controls what headers and libraries
   are seen by a package's configure and build processes.  This is implemented
   in a two step process:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>Symlink headers and libraries for dependencies into
       <code class="varname">BUILDLINK_DIR</code>, which by default is a subdirectory
       of <code class="varname">WRKDIR</code>.</p></li>
 <li class="listitem"><p>Create wrapper scripts that are used in place of the normal compiler
       tools that translate <code class="option">-I${LOCALBASE}/include</code> and
       <code class="option">-L${LOCALBASE}/lib</code> into references to
       <code class="varname">BUILDLINK_DIR</code>. The wrapper scripts also make
       native compiler on some operating systems look like GCC, so that
       packages that expect GCC won't require modifications to build with
       those native compilers.</p></li>
 </ol></div>
 <p>This normalizes the environment in which a package is built so that the
   package may be built consistently despite what other software may be
   installed. Please note that the normal system header and library paths,
   e.g. <code class="filename">/usr/include</code>,
   <code class="filename">/usr/lib</code>, etc., are always searched -- buildlink3 is
   designed to insulate the package build from non-system-supplied
   software.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="converting-to-buildlink3"></a>14.1. Converting packages to use buildlink3</h2></div></div></div>
 <p>The process of converting packages to use the buildlink3
     framework (<span class="quote">&#8220;<span class="quote">bl3ifying</span>&#8221;</span>) is fairly straightforward.
     The things to keep in mind are:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>Ensure that the build always calls the wrapper scripts
 	instead of the actual toolchain.  Some packages are tricky,
 	and the only way to know for sure is the check
 	<code class="filename">${WRKDIR}/.work.log</code> to see if the
 	wrappers are being invoked.</p></li>
 <li class="listitem"><p>Don't override <code class="varname">PREFIX</code> from within
 	the package Makefile, e.g. Java VMs, standalone shells,
 	etc., because the code to symlink files into
 	<code class="filename">${BUILDLINK_DIR}</code> looks for files
 	relative to <span class="quote">&#8220;<span class="quote">pkg_info -qp <em class="replaceable"><code>pkgname</code></em></span>&#8221;</span>.
 	</p></li>
 <li class="listitem"><p>Remember that <span class="emphasis"><em>only</em></span> the
 	<code class="filename">buildlink3.mk</code> files that you list in a
 	package's Makefile are added as dependencies for that package.
 	</p></li>
 </ol></div>
 <p>If a dependency on a particular package is required for its libraries and
     headers, then we replace:</p>
 <pre class="programlisting">
 DEPENDS+=       foo&gt;=1.1.0:../../category/foo
 </pre>
 <p>with</p>
 <pre class="programlisting">
 .include "../../category/foo/buildlink3.mk"
 </pre>
 <p>The buildlink3.mk files usually define the required dependencies.
     If you need a newer version of the dependency when using buildlink3.mk
     files, then you can define it in your Makefile; for example:</p>
 <pre class="programlisting">
 BUILDLINK_API_DEPENDS.foo+=   foo&gt;=1.1.0
 .include "../../category/foo/buildlink3.mk"
 </pre>
 <p>There are several <code class="filename">buildlink3.mk</code>
     files in <code class="filename">pkgsrc/mk</code>
     that handle special package issues:</p>

 <p>This section can additionally include any
       <code class="filename">buildlink3.mk</code> needed for
       <em class="replaceable"><code>pkg</code></em>'s library dependencies.
       Including these <code class="filename">buildlink3.mk</code> files
       means that the headers and libraries for these
       dependencies are also symlinked into
       <code class="filename">${BUILDLINK_DIR}</code>
       whenever the <em class="replaceable"><code>pkg</code></em>
       <code class="filename">buildlink3.mk</code>
       file is included. Dependencies are only added for directly
       include <code class="filename">buildlink3.mk</code> files.</p>
 <p>When providing a <code class="filename">buildlink3.mk</code> and
       including other <code class="filename">buildlink3.mk</code> files in it,
       please only add necessary ones, i.e., those whose libraries or
       header files are automatically exposed when the package is
       use.</p>
 <p>In particular, if only an executable
       (<code class="filename">bin/foo</code>) is linked against a library, that
       library does not need to be propagated in the
       <code class="filename">buildlink3.mk</code> file.</p>
 <p>The following steps should help you decide if a
       <code class="filename">buildlink3.mk</code> file needs to be included:
       </p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>Look at the installed header files: What
 	headers do they include? The packages providing these files
 	must be buildlinked.</p></li>
 <li class="listitem"><p>Run <code class="filename">ldd</code> on all installed
 	libraries and look against what other libraries they link.
 	Some of the packages providing these probably need to be
 	buildlinked; however, it's not automatic, since e.g. GTK on
 	some systems pulls in the X libraries, so they will show up in
 	the <code class="filename">ldd</code> output, while on others (like OS
 	X) it won't. <code class="filename">ldd</code> output can thus only be
 	used as a hint.</p></li>

 <p>These two variables differ in that one describes source
       compatibility (API) and the other binary compatibility (ABI).
       The difference is that a change in the API breaks compilation of
       programs while changes in the ABI stop compiled programs from
       running.</p>
 <p>Changes to the
       <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       variable in a <code class="filename">buildlink3.mk</code> file happen
       very rarely. One possible reason is that all packages depending
       on this already need a newer version. In case it is bumped see
       the description below.</p>
 <p>The most common example of an ABI change is that the major
       version of a shared library is increased. In this case,
       <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       should be adjusted to require at least the new package version.
       Then the packages that depend on this package need their
       <code class="varname">PKGREVISION</code>s increased and, if they have
       <code class="filename">buildlink3.mk</code> files, their
       <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       adjusted, too. This is needed so pkgsrc will require the correct
       package dependency and not settle for an older one when building
       the source.</p>
 <p>See <a class="xref" href="#dependencies" title="19.1.5. Handling dependencies">Section 19.1.5, &#8220;Handling dependencies&#8221;</a> for
       more information about dependencies on other packages,
       including the <code class="varname">BUILDLINK_ABI_DEPENDS</code> and
       <code class="varname">ABI_DEPENDS</code> definitions.</p>
 <p>Please take careful consideration before adjusting
       <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       or
       <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       as we don't want to cause unneeded package deletions and
       rebuilds.  In many cases, new versions of packages work just
       fine with older dependencies.</p>
 <p>Also it is not needed to set
       <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
       when it is identical to

 <p>The first section sets
       <code class="varname">IS_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
       depending on if <em class="replaceable"><code>pkg</code></em> really exists
       in the base system.  This should not be a base system software
       with similar functionality to <em class="replaceable"><code>pkg</code></em>;
       it should only be <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span> if the actual package is
       included as part of the base system.  This variable is only
       used internally within the <code class="filename">builtin.mk</code>
       file.</p>
 <p>The second section sets
       <code class="varname">BUILTIN_PKG.<em class="replaceable"><code>pkg</code></em></code>
       to the version of <em class="replaceable"><code>pkg</code></em> in the base
       system if it exists (if

       is <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>).  This variable is only used internally
       within the <code class="filename">builtin.mk</code> file.</p>
 <p>The third section sets
       <code class="varname">USE_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
       and is <span class="emphasis"><em>required</em></span> in all
       <code class="filename">builtin.mk</code> files.  The code in this
       section must make the determination whether the built-in
       software is adequate to satisfy the dependencies listed in
       <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>.
       This is typically done by comparing
       <code class="varname">BUILTIN_PKG.<em class="replaceable"><code>pkg</code></em></code>
       against each of the dependencies in
       <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>.
       <code class="varname">USE_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
       <span class="emphasis"><em>must</em></span> be set to the correct value by the
       end of the <code class="filename">builtin.mk</code> file.  Note that
       <code class="varname">USE_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>

 <p>The last section is guarded by

 <a name="native-or-pkgsrc-preference"></a>14.3.2. Global preferences for native or pkgsrc software</h3></div></div></div>
 <p>When building packages, it's possible to choose whether to set
 	a global preference for using either the built-in (native)
 	version or the pkgsrc version of software to satisfy a
 	dependency.  This is controlled by setting
 	<code class="varname">PREFER_PKGSRC</code> and
 	<code class="varname">PREFER_NATIVE</code>.  These variables take values
 	of either <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>, <span class="quote">&#8220;<span class="quote">no</span>&#8221;</span>, or a list of
 	packages.  <code class="varname">PREFER_PKGSRC</code> tells pkgsrc to
 	use the pkgsrc versions of software, while
 	<code class="varname">PREFER_NATIVE</code> tells pkgsrc to use the
 	built-in versions.  Preferences are determined by the most
 	specific instance of the package in either
 	<code class="varname">PREFER_PKGSRC</code> or
 	<code class="varname">PREFER_NATIVE</code>.  If a package is specified
 	in neither or in both variables, then
 	<code class="varname">PREFER_PKGSRC</code> has precedence over
 	<code class="varname">PREFER_NATIVE</code>.  For example, to require
 	using pkgsrc versions of software for all but the most basic
       bits on a NetBSD system, you can set:</p>
 <pre class="programlisting">
 PREFER_PKGSRC=  yes
 PREFER_NATIVE=  getopt skey tcp_wrappers
 </pre>
 <p>A package <span class="emphasis"><em>must</em></span> have a
       <code class="filename">builtin.mk</code>
       file to be listed in <code class="varname">PREFER_NATIVE</code>,
       otherwise it is simply ignored in that list.</p>
 <p>Setting <code class="varname">PREFER_NATIVE</code> should be performed
       straight after bootstrap and <code class="varname">PREFER_PKGSRC</code> during
       bootstrap.
       Switching between settings globally at a later date can introduce
       complications with dependency resolution. This is caused by packages
       built with the opposite preference being installed alongside each other.</p>

 <p>The following sections inspect each of the above points in detail.</p>
 <p>You may be thinking that many of the things described here could be
 easily done with simple code in the package's post-installation target
 (<code class="literal">post-install</code>).  <span class="emphasis"><em>This is incorrect</em></span>,
 as the code in them is only executed when building from source.  Machines
 using binary packages could not benefit from it at all (as the code itself
 could be unavailable).  Therefore, the only way to achieve any of the items
 described above is by means of the installation scripts, which are
 automatically generated by pkginstall.</p>

 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="files-and-dirs-outside-prefix"></a>15.1. Files and directories outside the installation prefix</h2></div></div></div>
 <p>As you already know, the <code class="filename">PLIST</code> file holds a list
 of files and directories that belong to a package.  The names used in it
 are relative to the installation prefix (<code class="filename">${PREFIX}</code>),
 which means that it cannot register files outside this directory (absolute
 path names are not allowed).  Despite this restriction, some packages need
 to install files outside this location; e.g., under
 <code class="filename">${VARBASE}</code> or
 <code class="filename">${PKG_SYSCONFDIR}</code>.  The only way to achieve this
 is to create such files during installation time by using
 installation scripts.</p>
 <p>The generic installation scripts are shell scripts that can
 contain arbitrary code.  The list of scripts to execute is taken from
 the <code class="varname">INSTALL_FILE</code> variable, which defaults to
 <code class="filename">INSTALL</code>.  A similar variable exists for package
 removal (<code class="varname">DEINSTALL_FILE</code>, whose default is
 <code class="filename">DEINSTALL</code>).  These scripts can run arbitrary
 commands, so they have the potential to create and manage files
 anywhere in the file system.</p>
 <p>Using these general installation files is not recommended, but
 may be needed in some special cases.  One reason for avoiding them is
 that the user has to trust the packager that there is no unwanted or
 simply erroneous code included in the installation script. Also,
 previously there were many similar scripts for the same functionality,
 and fixing a common error involved finding and changing all of
 them.</p>
 <p>The pkginstall framework offers another, standardized way.  It
 provides generic scripts to abstract the manipulation of such files
 and directories based on variables set in the package's
 <code class="filename">Makefile</code>.  The rest of this section describes
 these variables.</p>

 <li class="listitem">
 <p><code class="varname">MAKE_DIRS</code> and <code class="varname">OWN_DIRS</code>

     to be destroyed by the installation scripts.  The difference between
     the two is that the latter prompts the administrator to remove any
     directories that may be left after deinstallation (because they were
     not empty), while the former does not.  Example:</p>
 <pre class="programlisting">
 MAKE_DIRS+=             ${VARBASE}/foo/private
 </pre>
 </li>
 <li class="listitem">
 <p><code class="varname">MAKE_DIRS_PERMS</code> and
     <code class="varname">OWN_DIRS_PERMS</code> contain a list of tuples describing
     which directories should be created and should attempt to be destroyed

     separated by spaces: the directory name, its owner, its group and its
     numerical mode.  For example:</p>
 <pre class="programlisting">
 MAKE_DIRS_PERMS+=       ${VARBASE}/foo/private \
                         ${REAL_ROOT_USER} ${REAL_ROOT_GROUP} 0700

 <a name="files-outside-prefix"></a>15.1.2. File manipulation</h3></div></div></div>
 <p>Creating non-empty files outside the installation prefix is tricky
 because the <code class="filename">PLIST</code> forces all files to be inside it.
 To overcome this problem, the only solution is to extract the file in the
 known place (i.e., inside the installation prefix) and copy it to the
 appropriate location during installation (done by the installation scripts
 generated by pkginstall).  We will call the former the <span class="emphasis"><em>master
 file</em></span> in the following paragraphs, which describe the variables
 that can be used to automatically and consistently handle files outside the
 installation prefix:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem">
 <p><code class="varname">CONF_FILES</code> and
     <code class="varname">REQD_FILES</code> are pairs of master and target files.
     During installation time, the master file is copied to the target one
     if and only if the latter does not exist.  Upon deinstallation, the
     target file is removed provided that it was not modified by the
     installation.</p>
 <p>The difference between the two is that the latter prompts the
     administrator to remove any files that may be left after

     files as well as their target locations.  For each of them, it also
     specifies their owner, their group and their numeric permissions, in
     this order.  For example:</p>
 <pre class="programlisting">

 <p>Configuration files are special in the sense that they are installed
 in their own specific directory, <code class="varname">PKG_SYSCONFDIR</code>, and
 need special treatment during installation (most of which is automated by
 pkginstall).  The main concept you must bear in mind is that files marked
 as configuration files are automatically copied to the right place (somewhere
 inside <code class="varname">PKG_SYSCONFDIR</code>) during installation <span class="emphasis"><em>if

 be removed if they have local modifications.  This ensures that

 <p>As said before, the <code class="varname">PKG_SYSCONFDIR</code> variable
 specifies where configuration files shall be installed.  Its contents are
 set based upon the following variables:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><code class="varname">PKG_SYSCONFBASE</code>: The configuration's root
     directory.  Defaults to <code class="filename">${PREFIX}/etc</code> although it may
     be overridden by the user to point to his preferred location (e.g.,
     <code class="filename">/etc</code>, <code class="filename">/etc/pkg</code>, etc.).
     Packages must not use it directly.</p></li>

     variable only makes sense in the package's
     <code class="filename">Makefile</code> (i.e., it is not user-customizable).</p>
 <p>As an example, consider the Apache package,
-    <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/apache24/README.html" target="_top"><code class="filename">www/apache24</code></a>, which places its

     configuration files under the
     <code class="filename">httpd/</code> subdirectory of
     <code class="varname">PKG_SYSCONFBASE</code>.  This should be set in the package
     Makefile.</p>
 </li>
 <li class="listitem"><p><code class="varname">PKG_SYSCONFVAR</code>: Specifies the name of the
     variable that holds this package's configuration directory (if
     different from <code class="varname">PKG_SYSCONFBASE</code>).  It defaults to
     <code class="varname">PKGBASE</code>'s value, and is always prefixed with
     <code class="literal">PKG_SYSCONFDIR</code>.</p></li>
 <li class="listitem"><p><code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code>: Holds the
     directory where the configuration files for the package identified by
     <code class="varname">PKG_SYSCONFVAR</code>'s shall be placed.</p></li>
 </ul></div>
 <p>Based on the above variables, pkginstall determines the value of
 <code class="varname">PKG_SYSCONFDIR</code>, which is the <span class="emphasis"><em>only</em></span>
 variable that can be used within a package to refer to its configuration
 directory.  The algorithm used to set its value is basically the
 following:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>If <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> is set,
     its value is used.</p></li>
 <li class="listitem"><p>If the previous variable is not defined but
     <code class="varname">PKG_SYSCONFSUBDIR</code> is set in the package's

     <code class="filename">${PKG_SYSCONFBASE}/${PKG_SYSCONFSUBDIR}</code>.</p></li>
 <li class="listitem"><p>Otherwise, it is set to
     <code class="filename">${PKG_SYSCONFBASE}</code>.</p></li>
 </ol></div>
 <p>It is worth mentioning that <code class="filename">${PKG_SYSCONFDIR}</code> is
 automatically added to <code class="filename">OWN_DIRS</code>.  See <a class="xref" href="#dirs-outside-prefix" title="15.1.1. Directory manipulation">Section 15.1.1, &#8220;Directory manipulation&#8221;</a> what this means.  This does not apply to

 <a name="conf-files-configure"></a>15.2.2. Telling the software where configuration files are</h3></div></div></div>
 <p>Given that pkgsrc (and users!) expect configuration files to be in a
 known place, you need to teach each package where it shall install its
 files.  In some cases you will have to patch the package Makefiles to
 achieve it.  If you are lucky, though, it may be as easy as passing an
 extra flag to the configuration script; this is the case of GNU Autoconf-
 generated files:</p>
 <pre class="programlisting">
 CONFIGURE_ARGS+= --sysconfdir=${PKG_SYSCONFDIR}
 </pre>
 <p>Note that this specifies where the package has to <span class="emphasis"><em>look
 for</em></span> its configuration files, not where they will be originally
 installed (although the difference is never explicit,
 unfortunately).</p>

 <div class="titlepage"><div><div><h3 class="title">
 <a name="conf-files-patching"></a>15.2.3. Patching installations</h3></div></div></div>
 <p>As said before, pkginstall automatically handles configuration files.
 This means that <span class="strong"><strong>the packages themselves must not
 touch the contents of <code class="filename">${PKG_SYSCONFDIR}</code>
 directly</strong></span>.  Bad news is that many software installation scripts
 will, out of the box, mess with the contents of that directory.  So what is
 the correct procedure to fix this issue?</p>
 <p>You must teach the package (usually by manually patching it) to
 install any configuration files under the examples hierarchy,
 <code class="filename">share/examples/${PKGBASE}/</code>.  This way, the
 <code class="filename">PLIST</code> registers them and the administrator always
 has the original copies available.</p>
 <p>Once the required configuration files are in place (i.e., under the
 examples hierarchy), the pkginstall framework can use them as master copies
 during the package installation to update what is in
 <code class="filename">${PKG_SYSCONFDIR}</code>.  To achieve this, the variables
 <code class="varname">CONF_FILES</code> and <code class="varname">CONF_FILES_PERMS</code> are
 used.  Check out <a class="xref" href="#files-outside-prefix" title="15.1.2. File manipulation">Section 15.1.2, &#8220;File manipulation&#8221;</a> for information

 <p>System startup scripts are special files because they must be
 installed in a place known by the underlying OS, usually outside the
 installation prefix.  Therefore, the same rules described in <a class="xref" href="#files-and-dirs-outside-prefix" title="15.1. Files and directories outside the installation prefix">Section 15.1, &#8220;Files and directories outside the installation prefix&#8221;</a> apply, and the same solutions
 can be used.  However, pkginstall provides a special mechanism to handle
 these files.</p>
 <p>In order to provide system startup scripts, the package has
 to:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>Store the script inside <code class="filename">${FILESDIR}</code>, with
     the <code class="literal">.sh</code> suffix appended.  Considering the

 <li class="listitem">
 <p>Tell pkginstall to handle it, appending the name of the script,

     Continuing the previous example:</p>
 <pre class="programlisting">
 RCD_SCRIPTS+=   cupsd

 <p>If a package needs to create special users and/or groups during

 <p>Users can be created by adding entries to the
 <code class="varname">PKG_USERS</code> variable.  Each entry has the following
 syntax:</p>
 <pre class="programlisting">
 user:group
 </pre>
 <p>Further specification of user details may be done by setting
 per-user variables.
 <code class="varname">PKG_UID.<em class="replaceable"><code>user</code></em></code> is the
 numeric UID for the user.
 <code class="varname">PKG_GECOS.<em class="replaceable"><code>user</code></em></code> is the
 user's description or comment.
 <code class="varname">PKG_HOME.<em class="replaceable"><code>user</code></em></code> is the
 user's home directory, and defaults to
 <code class="filename">/nonexistent</code> if not specified.
 <code class="varname">PKG_SHELL.<em class="replaceable"><code>user</code></em></code> is the
 user's shell, and defaults to <code class="filename">/sbin/nologin</code> if
 not specified.</p>
 <p>Similarly, groups can be created by adding entries to the
 <code class="varname">PKG_GROUPS</code> variable, whose syntax is:</p>
 <pre class="programlisting">
 group
 </pre>
 <p>The numeric GID of the group may be set by defining
 <code class="varname">PKG_GID.<em class="replaceable"><code>group</code></em></code>.</p>
 <p>If a package needs to create the users and groups at an earlier
 stage, then it can set <code class="varname">USERGROUP_PHASE</code> to either
 <code class="literal">configure</code>,<code class="literal">build</code>, or
 <code class="literal">pre-install</code> to indicate the phase before which the
 users and groups are created. In this case, the numeric UIDs and GIDs
 of the created users and groups are automatically hardcoded into the

 <p>Packages that install X11 fonts should update the database files

 <p>When a package installs X11 fonts, it must list the directories in

 </div>
 <p>Many packages have the ability to be built to support different
 sets of features.  <code class="filename">bsd.options.mk</code> is a framework
 in pkgsrc that provides generic handling of those options that
 determine different ways in which the packages can be built.  It's
 possible for the user to specify exactly which sets of options will be
 built into a package or to allow a set of global default options
 apply.</p>
 <p>There are two broad classes of behaviors that one might want to
 control via options.  One is whether some particular feature is
 enabled in a program that will be built anyway, often by including or
 not including a dependency on some other package.  The other is
 whether or not an additional program will be built as part of the
 package.  Generally, it is better to make a split package for such
 additional programs instead of using options, because it enables
 binary packages to be built which can then be added separately.  For
 example, the foo package might have minimal dependencies (those
 packages without which foo doesn't make sense), and then the foo-gfoo
 package might include the GTK frontend program gfoo.  This is better
 than including a gtk option to foo that adds gfoo, because either that
 option is default, in which case binary users can't get foo without
 gfoo, or not default, in which case they can't get gfoo.  With split
 packages, they can install foo without having GTK, and later decide to
 install gfoo (pulling in GTK at that time).  This is an advantage to
 source users too, avoiding the need for rebuilds.</p>
 <p>Plugins with widely varying dependencies should usually be split
 instead of options.</p>
 <p>It is often more work to maintain split packages, especially if
 the upstream package does not support this.  The decision of split
 vs. option should be made based on the likelihood that users will want
 or object to the various pieces, the size of the dependencies that are
 included, and the amount of work.</p>
 <p>A further consideration is licensing.  Non-free parts, or parts
 that depend on non-free dependencies (especially plugins) should
 almost always be split if feasible.</p>

 <p>Options that enable similar features in different packages (like
 optional support for a library) should use a common name in all
 packages that support it (like the name of the library).  If another
 package already has an option with the same meaning, use the same
 name.</p>
 <p>Options that enable features specific to one package, where it's
 unlikely that another (unrelated) package has the same (or a similar)
 optional feature, should use a name prefixed with
 <code class="varname"><em class="replaceable"><code>pkgname</code></em>-</code>.</p>
 <p>If a group of related packages share an optional feature
 specific to that group, prefix it with the name of the
 <span class="quote">&#8220;<span class="quote">main</span>&#8221;</span> package
 (e. g. <code class="varname">djbware-errno-hack</code>).</p>
 <p>For new options, add a line to
 <code class="filename">mk/defaults/options.description</code>.  Lines have two
 fields, separated by tab.  The first field is the option name, the
 second its description.  The description should be a whole sentence
 (starting with an uppercase letter and ending with a period) that
 describes what enabling the option does.  E. g. <span class="quote">&#8220;<span class="quote">Enable ispell

 <p>When writing <a class="link" href="#buildlink3.mk"><code class="filename">buildlink3.mk</code></a> files, it is often necessary to list
 different dependencies based on the options with which the package was
 built. For querying these options, the file

 typical example looks like this:</p>

 <a name="build.intro"></a>17.1. Introduction</h2></div></div></div>
 <p>This chapter gives a detailed description on how a package is
     built. Building a package is separated into different
     <span class="emphasis"><em>phases</em></span> (for example <code class="varname">fetch</code>,
     <code class="varname">build</code>, <code class="varname">install</code>), all of which are
     described in the following sections. Each phase is split into
     so-called <span class="emphasis"><em>stages</em></span>, which take the name of the
     containing phase, prefixed by one of <code class="varname">pre-</code>,
     <code class="varname">do-</code> or <code class="varname">post-</code>. (Examples are
     <code class="varname">pre-configure</code>, <code class="varname">post-build</code>.) Most
     of the actual work is done in the <code class="varname">do-*</code> stages.</p>
 <p>Never override the regular targets (like
     <code class="varname">fetch</code>), if you have to, override the
     <code class="varname">do-*</code> ones instead.</p>
 <p>The basic steps for building a program are always the same.  First
     the program's source (<span class="emphasis"><em>distfile</em></span>) must be brought to
     the local system and then extracted. After any pkgsrc-specific patches
     to compile properly are applied, the software can be configured, then
     built (usually by compiling), and finally the generated binaries, etc.
     can be put into place on the system.</p>
 <p>To get more details about what is happening at each step,
     you can set the <code class="varname">PKG_VERBOSE</code> variable, or the
     <code class="varname">PATCH_DEBUG</code> variable if you are just interested
     in more details about the <span class="emphasis"><em>patch</em></span> step.</p>

 <a name="build.prefix"></a>17.2. Program location</h2></div></div></div>
 <p>Before outlining the process performed by the NetBSD package system in
     the next section, here's a brief discussion on where programs are
     installed, and which variables influence this.</p>
 <p>The automatic variable <code class="varname">PREFIX</code> indicates
     where all files of the final program shall be installed. It is
     usually set to <code class="varname">LOCALBASE</code>
     (<code class="filename">/usr/pkg</code>), or <code class="varname">CROSSBASE</code>
     for pkgs in the <code class="filename">cross</code> category.  The value of
     <code class="varname">PREFIX</code> needs to be put
     into the various places in the program's source where paths to
     these files are encoded.  See <a class="xref" href="#components.patches" title="11.3. patches/*">Section 11.3, &#8220;<code class="filename">patches/*</code>&#8221;</a> and <a class="xref" href="#fixes.libtool" title="19.3.1. Shared libraries - libtool">Section 19.3.1, &#8220;Shared libraries - libtool&#8221;</a> for more details.</p>
 <p>When choosing which of these variables to use,
     follow the following rules:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><code class="varname">PREFIX</code> always points to the location
 	where the current pkg will be installed.  When referring to a
 	pkg's own installation path, use
 	<span class="quote">&#8220;<span class="quote">${PREFIX}</span>&#8221;</span>.</p></li>
 <li class="listitem"><p><code class="varname">LOCALBASE</code> is where all non-X11 pkgs
 	are installed.  If you need to construct a -I or -L argument
 	to the compiler to find includes and libraries installed by
 	another non-X11 pkg, use <span class="quote">&#8220;<span class="quote">${LOCALBASE}</span>&#8221;</span>. The name
 	<code class="varname">LOCALBASE</code> stems from FreeBSD, which
 	installed all packages in <code class="filename">/usr/local</code>. As
 	pkgsrc leaves <code class="filename">/usr/local</code> for the system
 	administrator, this variable is a misnomer.</p></li>
 <li class="listitem"><p><code class="varname">X11BASE</code> is where the actual X11
 	distribution (from xsrc, etc.) is installed. When looking for
 	<span class="emphasis"><em>standard</em></span> X11 includes (not those
 	installed by a package), use <span class="quote">&#8220;<span class="quote">${X11BASE}</span>&#8221;</span>.</p></li>
 <li class="listitem"><p>X11-based packages using imake must set
 	<code class="varname">USE_IMAKE</code> to be installed correctly under

 <a name="build.builddirs"></a>17.3. Directories used during the build process</h2></div></div></div>
 <p>When building a package, various directories are used to store
     source files, temporary files, pkgsrc-internal files, and so on. These
     directories are explained here.</p>
 <p>Some of the directory variables contain relative pathnames. There
     are two common base directories for these relative directories:
     <code class="varname">PKGSRCDIR/PKGPATH</code> is used for directories that are
     pkgsrc-specific. <code class="varname">WRKSRC</code> is used for directories
     inside the package itself.</p>
 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term"><code class="varname">PKGSRCDIR</code></span></dt>
 <dd><p>This is an absolute pathname that points to the pkgsrc
       root directory. Generally, you don't need
       it.</p></dd>

 <dd><p>This is an absolute pathname pointing to the directory
       where all work takes place. The distfiles are extracted to this
       directory. It also contains temporary directories and log files used by
       the various pkgsrc frameworks, like <span class="emphasis"><em>buildlink</em></span> or
       the <span class="emphasis"><em>wrappers</em></span>.</p></dd>
 <dt><span class="term"><code class="varname">WRKSRC</code></span></dt>
 <dd><p>This is an absolute pathname pointing to the directory
       where the distfiles are extracted. It is usually a direct subdirectory
       of <code class="varname">WRKDIR</code>, and often it's the only directory entry
       that isn't hidden. This variable may be changed by a package
       <code class="filename">Makefile</code>.</p></dd>
 </dl></div>
 <p>The <code class="varname">CREATE_WRKDIR_SYMLINK</code> definition takes either
     the value <span class="emphasis"><em>yes</em></span> or <span class="emphasis"><em>no</em></span> and defaults
     to <span class="emphasis"><em>no</em></span>. It indicates whether a symbolic link to the
     <code class="varname">WRKDIR</code> is to be created in the pkgsrc entry's directory.
     If users would like to have their pkgsrc trees behave in a
     read-only manner, then the value of
     <code class="varname">CREATE_WRKDIR_SYMLINK</code> should be set to

 <div class="titlepage"><div><div><h2 class="title" style="clear: both">

 <p>You can run a particular phase by typing <span class="command"><strong>make

     phase. This will automatically run all phases that are required for this
     phase. The default phase is <code class="varname">build</code>, that is, when you

 <a name="build.fetch"></a>17.5. The <span class="emphasis"><em>fetch</em></span> phase</h2></div></div></div>
 <p>The first step in building a package is to fetch the
     distribution files (distfiles) from the sites that are providing
     them. This is the task of the <span class="emphasis"><em>fetch</em></span>
     phase.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="build.fetch.what"></a>17.5.1. What to fetch and where to get it from</h3></div></div></div>
 <p>In simple cases, <code class="varname">MASTER_SITES</code>
       defines all URLs from where the distfile, whose name is
       derived from the <code class="varname">DISTNAME</code> variable, is
       fetched. The more complicated cases are described
       below.</p>
 <p>The variable <code class="varname">DISTFILES</code> specifies
       the list of distfiles that have to be fetched. Its value
       defaults to <code class="literal">${DEFAULT_DISTFILES}</code> and
       its value is <code class="literal">${DISTNAME}${EXTRACT_SUFX}</code>,
       so that most packages don't need to define it at all.
       <code class="varname">EXTRACT_SUFX</code> is
       <code class="literal">.tar.gz</code> by default, but can be changed
       freely. Note that if your package requires additional
       distfiles to the default one, you cannot just append the
       additional filenames using the <code class="literal">+=</code>
       operator, but you have write for example:</p>
 <pre class="programlisting">
 DISTFILES=      ${DEFAULT_DISTFILES} additional-files.tar.gz
 </pre>
 <p>Each distfile is fetched from a list of sites, usually
       <code class="varname">MASTER_SITES</code>. If the package has multiple
       <code class="varname">DISTFILES</code> or multiple
       <code class="varname">PATCHFILES</code> from different sites, you can
       set
       <code class="varname">SITES.<em class="replaceable"><code>distfile</code></em></code>
       to the list of URLs where the file
       <code class="filename"><em class="replaceable"><code>distfile</code></em></code>
       (including the suffix) can be found.</p>
 <pre class="programlisting">
 DISTFILES=      ${DISTNAME}${EXTRACT_SUFX}
 DISTFILES+=     foo-file.tar.gz
 SITES.foo-file.tar.gz= \
 http://www.somewhere.com/somehow/ \
 http://www.somewhereelse.com/mirror/somehow/
 </pre>
 <p>When actually fetching the distfiles, each item from
       <code class="varname">MASTER_SITES</code> or
       <code class="varname">SITES.*</code> gets the name of each distfile
       appended to it, without an intermediate slash. Therefore,
       all site values have to end with a slash or other separator
       character. This allows for example to set
       <code class="varname">MASTER_SITES</code> to a URL of a CGI script
       that gets the name of the distfile as a parameter. In this
       case, the definition would look like:</p>
 <pre class="programlisting">
 MASTER_SITES=   http://www.example.com/download.cgi?file=
 </pre>
 <p> The exception to this rule are URLs starting with a dash.
       In that case the URL is taken as is, fetched and the result
       stored under the name of the distfile. You can use this style
       for the case when the download URL style does not match the
       above common case. For example, if permanent download URL is a
       redirector to the real download URL, or the download file name
       is offered by an HTTP Content-Disposition header. In the
       following example, <code class="filename">foo-1.0.0.tar.gz</code> will be
       created instead of the default
       <code class="filename">v1.0.0.tar.gz</code>.</p>

 <p>There are some predefined values for
       <code class="varname">MASTER_SITES</code>, which can be used in
       packages.  The names of the variables should speak for

 <p>Some explanations for the less self-explaining ones:
       <code class="varname">MASTER_SITE_BACKUP</code> contains backup sites
       for packages that are maintained in <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/%24%7BDIST_SUBDIR%7D" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/${DIST_SUBDIR}</a>.  <code class="varname">MASTER_SITE_LOCAL</code> contains local

 <p>If you choose one of these predefined sites, you may
       want to specify a subdirectory of that site. Since these
       macros may expand to more than one actual site, you
       <span class="emphasis"><em>must</em></span> use the following construct to
       specify a subdirectory:</p>
 <pre class="programlisting">
 MASTER_SITES=   ${MASTER_SITE_GNU:=subdirectory/name/}
 MASTER_SITES=   ${MASTER_SITE_SOURCEFORGE:=project_name/}
 </pre>
 <p>Note the trailing slash after the subdirectory
       name.</p>

 <a name="build.fetch.how"></a>17.5.2. How are the files fetched?</h3></div></div></div>
 <p>The <span class="emphasis"><em>fetch</em></span> phase makes sure that
       all the distfiles exist in a local directory
       (<code class="varname">DISTDIR</code>, which can be set by the pkgsrc
       user). If the files do not exist, they are fetched using
       commands of the form</p>
 <pre class="programlisting">
 ${FETCH_CMD} ${FETCH_BEFORE_ARGS} ${site}${file} ${FETCH_AFTER_ARGS}
 </pre>
 <p>where <code class="literal">${site}</code> varies through
       several possibilities in turn: first,
       <code class="varname">MASTER_SITE_OVERRIDE</code> is tried, then the
       sites specified in either <code class="varname">SITES.file</code> if
       defined, else <code class="varname">MASTER_SITES</code> or
       <code class="varname">PATCH_SITES</code>, as applies, then finally the
       value of <code class="varname">MASTER_SITE_BACKUP</code>. The order of
       all except the first and the last can be optionally sorted
       by the user, via setting either
       <code class="varname">MASTER_SORT_RANDOM</code>, and
       <code class="varname">MASTER_SORT_AWK</code> or
       <code class="varname">MASTER_SORT_REGEX</code>.</p>
 <p> The specific command and arguments used depend on the
       <code class="varname">FETCH_USING</code> parameter. The example above is
       for <code class="literal">FETCH_USING=custom</code>.</p>
 <p>The distfiles mirror run by the NetBSD Foundation uses the
       <span class="emphasis"><em>mirror-distfiles</em></span> target to mirror the
       distfiles, if they are freely distributable.  Packages setting
       <code class="varname">NO_SRC_ON_FTP</code> (usually to
       <span class="quote">&#8220;<span class="quote">${RESTRICTED}</span>&#8221;</span>) will not have their distfiles

 <p>After the distfile(s) are fetched, their checksum is
     generated and compared with the checksums stored in the
     distinfo file. If the checksums don't match, the build is
     aborted. This is to ensure the same distfile is used for
     building, and that the distfile wasn't changed, e.g. by some
     malign force, deliberately changed distfiles on the master

 <a name="build.extract"></a>17.7. The <span class="emphasis"><em>extract</em></span> phase</h2></div></div></div>
 <p>When the distfiles are present on the local system, they
     need to be extracted, as they usually come in the form of some
     compressed archive format.</p>
 <p>By default, all <code class="varname">DISTFILES</code> are
     extracted. If you only need some of them, you can set the
     <code class="varname">EXTRACT_ONLY</code> variable to the list of those
     files.</p>
 <p>Extracting the files is usually done by a little
     program, <code class="filename">mk/extract/extract</code>, which
     already knows how to extract various archive formats, so most
     likely you will not need to change anything here. But if you
     need, the following variables may help you:</p>
 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term"><code class="varname">EXTRACT_OPTS_{BIN,LHA,PAX,RAR,TAR,ZIP,ZOO}</code></span></dt>
 <dd><p>Use these variables to override the default
       options for an extract command, which are defined in
       <code class="filename">mk/extract/extract</code>.</p></dd>
 <dt><span class="term"><code class="varname">EXTRACT_USING</code></span></dt>
 <dd><p>This variable can be set to
       <code class="literal">bsdtar</code>, <code class="literal">gtar</code>, <code class="literal">nbtar</code>
       (which is the default value), <code class="literal">pax</code>, or an
       absolute pathname pointing to the command with which tar
       archives should be extracted.  It is preferred to choose bsdtar over gtar
       if NetBSD's pax-as-tar is not good enough.</p></dd>
 </dl></div>
 <p>If the <code class="filename">extract</code> program doesn't
     serve your needs, you can also override the
     <code class="varname">EXTRACT_CMD</code> variable, which holds the
     command used for extracting the files. This command is
     executed in the <code class="filename">${WRKSRC}</code>
     directory. During execution of this command, the shell
     variable <code class="varname">extract_file</code> holds the absolute
     pathname of the file that is going to be extracted.</p>
 <p>And if that still does not suffice, you can override the
     <code class="varname">do-extract</code> target in the package
     Makefile.</p>

 <p>Most pieces of software need information on the header
     files, system calls, and library routines which are available
     on the platform they run on. The process of determining this
     information is known as configuration, and is usually
     automated. In most cases, a script is supplied with the
     distfiles, and its invocation results in generation of header
     files, Makefiles, etc.</p>
 <p>If the package contains a configure script, this can be
     invoked by setting <code class="varname">HAS_CONFIGURE</code> to
     <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>. If the configure script is a GNU autoconf
     script, you should set <code class="varname">GNU_CONFIGURE</code> to
     <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span> instead. What happens in the
     <span class="emphasis"><em>configure</em></span> phase is roughly:</p>
 <pre class="programlisting">
 .for d in ${CONFIGURE_DIRS}
         cd ${WRKSRC} \
         &amp;&amp; cd ${d} \

 .endfor
 </pre>
 <p><code class="varname">CONFIGURE_DIRS</code> (default:
     <span class="quote">&#8220;<span class="quote">.</span>&#8221;</span>) is a list of pathnames relative to
     <code class="varname">WRKSRC</code>. In each of these directories, the
     configure script is run with the environment
     <code class="varname">CONFIGURE_ENV</code> and arguments
     <code class="varname">CONFIGURE_ARGS</code>. The variables
     <code class="varname">CONFIGURE_ENV</code>,

     <span class="quote">&#8220;<span class="quote">./configure</span>&#8221;</span>) and
     <code class="varname">CONFIGURE_ARGS</code> may all be changed by the
     package.</p>
 <p>If the program uses the Perl way of configuration (mainly Perl
     modules, but not only), i.e. a file called
     <code class="filename">Makefile.PL</code>, it should include
     <code class="filename">../../lang/perl5/module.mk</code>. To set any parameter for
     <code class="filename">Makefile.PL</code> use the <code class="varname">MAKE_PARAMS</code>
     variable (e.g., <code class="literal">MAKE_PARAMS+=foo=bar</code></p>
 <p>If the program uses an <code class="filename">Imakefile</code>
     for configuration, the appropriate steps can be invoked by
     setting <code class="varname">USE_IMAKE</code> to
     <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>.  If you only need xmkmf, add it to <code class="varname">USE_TOOLS</code>.
     You can add variables to xmkmf's environment by adding them to the
     <code class="varname">SCRIPTS_ENV</code> variable.</p>
 <p>If the program uses <code class="filename">cmake</code>
     for configuration, the appropriate steps can be invoked by
     setting <code class="varname">USE_CMAKE</code> to <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>.
     You can add variables to cmake's environment by adding them to the
     <code class="varname">CONFIGURE_ENV</code> variable and arguments to cmake
     by adding them to the <code class="varname">CMAKE_ARGS</code> variable.
     The top directory argument is given by the
     <code class="varname">CMAKE_ARG_PATH</code> variable, that defaults to
     <span class="quote">&#8220;<span class="quote">.</span>&#8221;</span> (relative to <code class="varname">CONFIGURE_DIRS</code>)</p>
 <p>If there is no configure step at all, set

 <p>The <code class="varname">USE_TOOLS</code> definition is used both internally
 by pkgsrc and also for individual packages to define what commands
 are needed for building a package (like <code class="varname">BUILD_DEPENDS</code>)
 or for later run-time of an installed packaged (such as
 <code class="varname">DEPENDS</code>).
 If the native system provides an adequate tool, then in many cases, a pkgsrc
 package will not be used.</p>
 <p>When building a package, the replacement tools are
 made available in a directory (as symlinks or wrapper scripts)
 that is early in the executable search path. Just like the buildlink
 system, this helps with consistent builds.</p>
 <p>A tool may be needed to help build a specific package. For example,
 perl, GNU make (gmake) or yacc may be needed.</p>
 <p>Also a tool may be needed, for example, because the native system's supplied
 tool may be inefficient for building a package with pkgsrc.
 For example, a package may need GNU awk, bison (instead of
 yacc) or a better sed.</p>
 <p>The tools used by a package can be listed by running
 <span class="command"><strong>make show-tools</strong></span>.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="pkgsrc-tools"></a>18.1. Tools for pkgsrc builds</h2></div></div></div>
 <p>The default set of tools used by pkgsrc is defined in
 <code class="filename">bsd.pkg.mk</code>. This includes standard Unix tools,
 such as: <span class="command"><strong>cat</strong></span>, <span class="command"><strong>awk</strong></span>,
 <span class="command"><strong>chmod</strong></span>, <span class="command"><strong>test</strong></span>, and so on.
 These can be seen by running:
 <span class="command"><strong>make show-var VARNAME=USE_TOOLS</strong></span>.</p>
 <p>If a package needs a specific program to build
 then the <code class="varname">USE_TOOLS</code> variable can be used
 to define the tools needed.</p>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="package-tools"></a>18.2. Tools needed by packages</h2></div></div></div>
 <p>In the following examples, the :run means that it is needed at
 run-time (and becomes a DEPENDS).
 The default is a build dependency which can be set with
 :build. (So in this example, it is the same as gmake:build
 and pkg-config:build.)</p>
 <pre class="programlisting">
 USE_TOOLS+=     gmake perl:run pkg-config
 </pre>
 <p>When using the tools framework, a
 <code class="varname">TOOLS_PATH.foo</code> variable is defined
 which contains the full path to the appropriate tool. For example,
 <code class="varname">TOOLS_PATH.bash</code> could be <span class="quote">&#8220;<span class="quote">/bin/bash</span>&#8221;</span>
 on Linux systems.</p>
 <p>If you always need a pkgsrc version of the
 tool at run-time, then just use <code class="varname">DEPENDS</code> instead.

 <p>When improving or porting pkgsrc to a new platform, have a look

 <code class="filename">pkgsrc/mk/tools/tools.${OPSYS}.mk</code> which defines

 <a name="general-operation"></a>19.1. General operation</h2></div></div></div>
 <p>One appealing feature of pkgsrc is that it runs on many
   different platforms. As a result, it is important to ensure,
   where possible, that packages in pkgsrc are portable. This
   chapter mentions some particular details you should pay
   attention to while working on pkgsrc.</p>

 </h3></div></div></div>
 <p>The pkgsrc user can configure pkgsrc by overriding several
     variables in the file pointed to by <code class="varname">MAKECONF</code>,
     which is <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> by default. When you
     want to use those variables in the preprocessor directives of
-    <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> (for example <code class="literal">.if</code> or

     <code class="literal">.for</code>), you need to include the file
     <code class="filename">../../mk/bsd.prefs.mk</code> before, which in turn
     loads the user preferences.</p>
 <p>But note that some variables may not be completely defined
     after <code class="filename">../../mk/bsd.prefs.mk</code> has been
     included, as they may contain references to variables that are
     not yet defined. In shell commands (the lines in
     <code class="filename">Makefile</code> that are indented with a tab) this
     is no problem, since variables are only expanded when they are
     used. But in the preprocessor directives mentioned above and in
     dependency lines (of the form <code class="literal">target:
     dependencies</code>) the variables are expanded at load
     time.</p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">

 <a name="user-interaction"></a>19.1.2. User interaction</h3></div></div></div>
 <p>Occasionally, packages require interaction from the user,
     and this can be in a number of ways:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>When fetching the distfiles, some packages require user

 <li class="listitem"><p>help during the build process</p></li>
 <li class="listitem"><p>help during the installation of a package</p></li>
 </ul></div>
 <p>A package can set the <code class="varname">INTERACTIVE_STAGE</code>
     variable to define which stages need interaction. This should be
     done in the package's <code class="filename">Makefile</code>, e.g.:</p>
 <pre class="programlisting">
 INTERACTIVE_STAGE=      configure install
 </pre>
 <p>The user can then decide to skip this package by setting the
     <code class="varname">BATCH</code> variable. Packages that require interaction
     are also excluded from bulk builds.</p>

 <a name="handling-licenses"></a>19.1.3. Handling licenses</h3></div></div></div>
 <p>Authors of software can choose the licence under which software
     can be copied.  The Free Software Foundation has declared some
     licenses "Free", and the Open Source Initiative has a definition of
     "Open Source".</p>
 <p>By default, pkgsrc allows packages with Free or Open Source
     licenses to be built.  To allow packages with other licenses to be
     built as well, the pkgsrc user needs to add these licenses to the
     <code class="varname">ACCEPTABLE_LICENSES</code> variable in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.  Note
     that this variable only affects which packages may be
     <span class="emphasis"><em>built</em></span>, while the license terms often also
     restrict the actual use of the package and its redistribution.</p>
 <p>One might want to only install packages with a BSD license,
     or the GPL, and not the other.  The free licenses are added to the
     default <code class="varname">ACCEPTABLE_LICENSES</code> variable.  The pkgsrc
     user can override the default by setting the
     <code class="varname">ACCEPTABLE_LICENSES</code> variable with "=" instead
     of "+=".  The licenses accepted by default are defined in the
     <code class="varname">DEFAULT_ACCEPTABLE_LICENSES</code> variable in the file
     <code class="filename">pkgsrc/mk/license.mk</code>.</p>
 <p>The license tag mechanism is intended to address
     copyright-related issues surrounding building, installing and
     using a package, and not to address redistribution issues (see
     <code class="varname">RESTRICTED</code> and
     <code class="varname">NO_SRC_ON_FTP</code>, etc.).
     Packages with redistribution restrictions should set these
     tags.</p>
 <p>Denoting that a package may be copied according to a
     particular license is done by placing the license in
     <code class="filename">pkgsrc/licenses</code> and setting the
     <code class="varname">LICENSE</code> variable to a string identifying the
-    license, e.g. in <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/graphics/xv/README.html" target="_top"><code class="filename">graphics/xv</code></a>:</p>
+    license, e.g. in <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/graphics/xv/README.html" target="_top"><code class="filename">graphics/xv</code></a>:</p>
 <pre class="programlisting">
 LICENSE=        xv-license
 </pre>
 <p>When trying to build, the user will get a notice that the
     package is covered by a license which has not been placed in the
     <code class="varname">ACCEPTABLE_LICENSES</code> variable:</p>
 <pre class="programlisting">
 <code class="prompt">%</code> <strong class="userinput"><code>make</code></strong>
 ===&gt; xv-3.10anb9 has an unacceptable license: xv-license.
 ===&gt;     To view the license, enter "/usr/bin/make show-license".
 ===&gt;     To indicate acceptance, add this line to your /etc/mk.conf:
 ===&gt;     ACCEPTABLE_LICENSES+=xv-license
 *** Error code 1
 </pre>
 <p>The license can be viewed with <span class="command"><strong>make
     show-license</strong></span>, and if the user so chooses, the line
     printed above can be added to <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to
     convey to pkgsrc that it should not in the future fail because of
     that license:</p>
 <pre class="programlisting">
 ACCEPTABLE_LICENSES+=xv-license
 </pre>
 <p>The use of <code class="varname">LICENSE=shareware</code>,
     <code class="varname">LICENSE=no-commercial-use</code>, and similar language
     is deprecated because it does not crisply refer to a particular
     license text.  Another problem with such usage is that it does not
     enable a user to tell pkgsrc to proceed for a single package
     without also telling pkgsrc to proceed for all packages with that
     tag.</p>

 <p>When the license changes (in a way other than formatting),
     make sure that the new license has a different name (e.g.,
     append the version number if it exists, or the date).  Just
     because a user told pkgsrc to build programs under a previous
     version of a license does not mean that pkgsrc should build
     programs under the new licenses.  The higher-level point is that
     pkgsrc does not evaluate licenses for reasonableness; the only
     test is a mechanistic test of whether a particular text has been
     approved by either of two bodies (FSF or OSI).</p>

 </div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="restricted-packages"></a>19.1.4. Restricted packages</h3></div></div></div>
 <p>Some licenses restrict how software may be re-distributed.
     By declaring the restrictions, package tools can
     automatically refrain from e.g. placing binary packages on FTP
     sites.</p>
 <p>There are four possible restrictions, which are
     the cross product of sources (distfiles) and binaries not being
     placed on FTP sites and CD-ROMs.  Because this is rarely the exact
     language in any license, and because non-Free licenses tend to be
     different from each other, pkgsrc adopts a definition of FTP and
     CD-ROM.
     "FTP" means making the source or binary file available over the
     Internet at no charge.
     "CD-ROM" means making the source or binary available on some kind of
     media, together with other source and binary packages, which is sold
     for a distribution charge.
     </p>
 <p>In order to encode these restrictions, the package system
     defines five make variables that can be set to note these
     restrictions:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem">
 <p><code class="varname">RESTRICTED</code></p>
 <p>This variable should be set whenever a restriction
 	exists (regardless of its kind).  Set this variable to a
 	string containing the reason for the restriction.  It should
 	be understood that those wanting to understand the restriction
 	will have to read the license, and perhaps seek advice of
 	counsel.</p>
 </li>
 <li class="listitem">
 <p><code class="varname">NO_BIN_ON_CDROM</code></p>
 <p>Binaries may not be placed on CD-ROM containing other

 <a name="dependencies"></a>19.1.5. Handling dependencies</h3></div></div></div>
 <p>Your package may depend on some other package being present
     - and there are various ways of expressing this dependency.
     pkgsrc supports the <code class="varname">BUILD_DEPENDS</code> and
     <code class="varname">DEPENDS</code> definitions, the
     <code class="varname">USE_TOOLS</code> definition, as well as dependencies
     via <code class="filename">buildlink3.mk</code>, which is the preferred way
     to handle dependencies, and which uses the variables named above.
     See <a class="xref" href="#buildlink" title="Chapter 14. Buildlink methodology">Chapter 14, <i>Buildlink methodology</i></a> for more information.</p>
 <p>The basic difference between the two variables is as
     follows: The <code class="varname">DEPENDS</code> definition registers
     that pre-requisite in the binary package so it will be pulled in
     when the binary package is later installed, whilst the
     <code class="varname">BUILD_DEPENDS</code> definition does not, marking a
     dependency that is only needed for building the package.</p>
 <p>This means that if you only need a package present whilst
     you are building, it should be noted as a
     <code class="varname">BUILD_DEPENDS</code>.</p>
 <p>The format for a <code class="varname">BUILD_DEPENDS</code> and a
     <code class="varname">DEPENDS</code> definition is:</p>

 <a name="not-building-packages"></a>19.1.7. Packages that cannot or should not be built</h3></div></div></div>
 <p>There are several reasons why a package might be
     instructed to not build under certain circumstances.  If the
     package builds and runs on most platforms, the exceptions
     should be noted with <code class="varname">BROKEN_ON_PLATFORM</code>.  If
     the package builds and runs on a small handful of platforms,
     set <code class="varname">BROKEN_EXCEPT_ON_PLATFORM</code> instead.
     Both <code class="varname">BROKEN_ON_PLATFORM</code> and
     <code class="varname">BROKEN_EXCEPT_ON_PLATFORM</code> are OS triples
     (OS-version-platform) that can use glob-style
     wildcards.</p>
 <p>If a package is not appropriate for some platforms (as
     opposed to merely broken), a different set of variables should be
     used as this affects failure reporting and statistics.
     If the package is appropriate for most platforms, the exceptions
     should be noted with <code class="varname">NOT_FOR_PLATFORM</code>.  If
     the package is appropriate for only a small handful of platforms
     (often exactly one), set <code class="varname">ONLY_FOR_PLATFORM</code> instead.
     Both <code class="varname">ONLY_FOR_PLATFORM</code> and
     <code class="varname">NOT_FOR_PLATFORM</code> are OS triples
     (OS-version-platform) that can use glob-style
     wildcards.</p>
 <p>Some packages are tightly bound to a specific version of an
-    operating system, e.g. LKMs or <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/sysutils/lsof/README.html" target="_top"><code class="filename">sysutils/lsof</code></a>.  Such binary packages are not

     backwards compatible with other versions of the OS, and should be
     uploaded to a version specific directory on the FTP server.  Mark
     these packages by setting <code class="varname">OSVERSION_SPECIFIC</code> to
     <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>.  This variable is not currently used by any of
     the package system internals, but may be used in the
     future.</p>
 <p>If the package should be skipped (for example, because it
     provides functionality already provided by the system), set
     <code class="varname">PKG_SKIP_REASON</code> to a descriptive message.  If

 <a name="bumping-pkgrevision"></a>19.1.10. How to handle incrementing versions when fixing an existing package</h3></div></div></div>
 <p>When making fixes to an existing package it can be useful
     to change the version number in <code class="varname">PKGNAME</code>. To
     avoid conflicting with future versions by the original author, a
     <span class="quote">&#8220;<span class="quote">nb1</span>&#8221;</span>, <span class="quote">&#8220;<span class="quote">nb2</span>&#8221;</span>, ... suffix can be used
     on package versions by setting <code class="varname">PKGREVISION=1</code>
     (2, ...). The <span class="quote">&#8220;<span class="quote">nb</span>&#8221;</span> is treated like a
     <span class="quote">&#8220;<span class="quote">.</span>&#8221;</span> by the package tools. e.g.</p>
 <pre class="programlisting">
 DISTNAME=       foo-17.42
 PKGREVISION=    9
 </pre>
 <p>will result in a <code class="varname">PKGNAME</code> of
     <span class="quote">&#8220;<span class="quote">foo-17.42nb9</span>&#8221;</span>. If you want to use the original
     value of <code class="varname">PKGNAME</code> without the <span class="quote">&#8220;<span class="quote">nbX</span>&#8221;</span>
     suffix, e.g. for setting <code class="varname">DIST_SUBDIR</code>, use
     <code class="varname">PKGNAME_NOREV</code>.</p>
 <p>When a new release of the package is released, the
     <code class="varname">PKGREVISION</code> should be removed, e.g. on a new
     minor release of the above package, things should be like:</p>
 <pre class="programlisting">
 DISTNAME=       foo-17.43
 </pre>
 <p><code class="varname">PKGREVISION</code> should be incremented for any
     non-trivial change in the resulting binary package.  Without a

 <a name="fixes.subst"></a>19.1.11. Substituting variable text in the package files (the SUBST framework)</h3></div></div></div>
 <p>When you want to replace the same text in multiple files
     or when the replacement text varies, patches alone cannot help.
     This is where the SUBST framework comes in. It provides an
     easy-to-use interface for replacing text in files.
     Example:</p>
 <pre class="programlisting">
 SUBST_CLASSES+=                 fix-paths
 SUBST_STAGE.fix-paths=          pre-configure
 SUBST_MESSAGE.fix-paths=        Fixing absolute paths.
 SUBST_FILES.fix-paths=          src/*.c
 SUBST_FILES.fix-paths+=         scripts/*.sh
 SUBST_SED.fix-paths=            -e 's,"/usr/local,"${PREFIX},g'
 SUBST_SED.fix-paths+=           -e 's,"/var/log,"${VARBASE}/log,g'
 </pre>
 <p><code class="varname">SUBST_CLASSES</code> is a list of identifiers
     that are used to identify the different SUBST blocks that are
     defined. The SUBST framework is heavily used by pkgsrc, so it is
     important to always use the <code class="literal">+=</code> operator with
     this variable. Otherwise some substitutions may be
     skipped.</p>
 <p>The remaining variables of each SUBST block are
     parameterized with the identifier from the first line
     (<code class="literal">fix-paths</code> in this case.) They can be seen as
     parameters to a function call.</p>
 <p><code class="varname">SUBST_STAGE.*</code> specifies the stage at
     which the replacement will take place. All combinations of
     <code class="literal">pre-</code>, <code class="literal">do-</code> and
     <code class="literal">post-</code> together with a phase name are
     possible, though only few are actually used. Most commonly used
     are <code class="literal">post-patch</code> and
     <code class="literal">pre-configure</code>. Of these two,
     <code class="literal">pre-configure</code> should be preferred because
     then it is possible to run <span class="command"><strong>bmake patch</strong></span> and
     have the state after applying the patches but before making any
     other changes. This is especially useful when you are debugging
     a package in order to create new patches for it. Similarly,
     <code class="literal">post-build</code> is preferred over
     <code class="literal">pre-install</code>, because the install phase should
     generally be kept as simple as possible. When you use
     <code class="literal">post-build</code>, you have the same files in the
     working directory that will be installed later, so you can check
     if the substitution has succeeded.</p>
 <p><code class="varname">SUBST_MESSAGE.*</code> is an optional text
     that is printed just before the substitution is done.</p>
 <p><code class="varname">SUBST_FILES.*</code> is the list of shell
     globbing patterns that specifies the files in which the
     substitution will take place. The patterns are interpreted
     relatively to the <code class="varname">WRKSRC</code> directory.</p>
 <p><code class="varname">SUBST_SED.*</code> is a list of arguments to
-    <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?sed+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">sed</span>(1)</span></a> that specify the actual substitution. Every sed

     command should be prefixed with <code class="literal">-e</code>, so that
     all SUBST blocks look uniform.</p>
 <p>There are some more variables, but they are so seldomly
     used that they are only documented in the

     compared against the old one before changing anything, to make
     sure the distfile was really updated on purpose, and that
     no trojan horse or so crept in.
     Please mention that the distfiles were compared and what was found
     in your commit message.</p>
 <p>Then, the correct way to work around this is to set
     <code class="varname">DIST_SUBDIR</code> to a unique directory name, usually
     based on <code class="varname">PKGNAME_NOREV</code> (but take care with
     python or ruby packages, where <code class="varname">PKGNAME</code> includes
     a variable prefix). All <code class="varname">DISTFILES</code> and
     <code class="varname">PATCHFILES</code> for this package will be put in that
     subdirectory of the local distfiles directory. (See <a class="xref" href="#bumping-pkgrevision" title="19.1.10. How to handle incrementing versions when fixing an existing package">Section 19.1.10, &#8220;How to handle incrementing versions when fixing an existing package&#8221;</a> for more details.) In case this
     happens more often, <code class="varname">PKGNAME</code> can be used (thus
     including the <code class="filename">nbX</code> suffix) or a date stamp can
     be appended, like
     <code class="varname">${PKGNAME_NOREV}-YYYYMMDD</code>.</p>
 <p><code class="varname">DIST_SUBDIR</code> is also used when a distfile's name does not contain a version and the distfile is apt to change. In cases where the likelihood of this is very small, <code class="varname">DIST_SUBDIR</code> might not be required. Additionally, <code class="varname">DIST_SUBDIR</code> must not be removed unless the distfile name changes, even if a package is being moved or renamed.</p>
 <p>Do not forget regenerating the <code class="filename">distinfo</code> file
     after that, since it contains the <code class="varname">DIST_SUBDIR</code>
     path in the filenames.
     Also, increase the PKGREVISION if the installed package is different.
     Furthermore, a mail to the package's authors seems appropriate
     telling them that changing distfiles after releases without
     changing the file names is not good practice.</p>

     can help here, as it just <span class="quote">&#8220;<span class="quote">knows</span>&#8221;</span> how to build
     both static and dynamic libraries from a set of source files,
     thus being platform-independent.</p>
 <p>Here's how to use libtool in a package in seven simple
     steps:</p>
 <div class="orderedlist"><ol class="orderedlist" type="1">
 <li class="listitem"><p>Add <code class="varname">USE_LIBTOOL=yes</code> to the package
 	Makefile.</p></li>
 <li class="listitem"><p>For library objects, use <span class="quote">&#8220;<span class="quote">${LIBTOOL} --mode=compile
 	${CC}</span>&#8221;</span> in place of <span class="quote">&#8220;<span class="quote">${CC}</span>&#8221;</span>. You could even
 	add it to the definition of <code class="varname">CC</code>, if only
 	libraries are being built in a given Makefile. This one command
 	will build both PIC and non-PIC library objects, so you need not
 	have separate shared and non-shared library rules.</p></li>
 <li class="listitem">
 <p>For the linking of the library, remove any
 	<span class="quote">&#8220;<span class="quote">ar</span>&#8221;</span>, <span class="quote">&#8220;<span class="quote">ranlib</span>&#8221;</span>, and <span class="quote">&#8220;<span class="quote">ld
 	-Bshareable</span>&#8221;</span> commands, and instead use:</p>
 <pre class="programlisting">
 ${LIBTOOL} --mode=link \
     ${CC} -o ${.TARGET:.a=.la} \
         ${OBJS:.o=.lo} \
         -rpath ${PREFIX}/lib \
         -version-info major:minor
 </pre>
 <p>Note that the library is changed to have a
 	<code class="filename">.la</code> extension, and the objects are
 	changed to have a <code class="filename">.lo</code>
 	extension. Change <code class="varname">OBJS</code> as
 	necessary. This automatically creates all of the
 	<code class="filename">.a</code>,
 	<code class="filename">.so.major.minor</code>, and ELF symlinks (if
 	necessary) in the build directory. Be sure to include
 	<span class="quote">&#8220;<span class="quote">-version-info</span>&#8221;</span>, especially when major and
 	minor are zero, as libtool will otherwise strip off the
 	shared library version.</p>
 <p>From the libtool manual:</p>
 <pre class="programlisting">
 So, libtool library versions are described by three integers:
 CURRENT
 The most recent interface number that this library implements.
 REVISION
 The implementation number of the CURRENT interface.
 AGE
 The difference between the newest and oldest interfaces that
 this library implements.  In other words, the library implements
 all the interface numbers in the range from number `CURRENT -
 AGE' to `CURRENT'.
 If two libraries have identical CURRENT and AGE numbers, then the
 dynamic linker chooses the library with the greater REVISION number.
 </pre>
 <p>The <span class="quote">&#8220;<span class="quote">-release</span>&#8221;</span> option will produce
 	different results for a.out and ELF (excluding symlinks)
 	in only one case. An ELF library of the form
 	<span class="quote">&#8220;<span class="quote">libfoo-release.so.<span class="emphasis"><em>x</em></span>.<span class="emphasis"><em>y</em></span></span>&#8221;</span>
 	will have a symlink of
 	<span class="quote">&#8220;<span class="quote">libfoo.so.<span class="emphasis"><em>x</em></span>.<span class="emphasis"><em>y</em></span></span>&#8221;</span>
 	on an a.out platform. This is handled
 	automatically.</p>
 <p>The <span class="quote">&#8220;<span class="quote">-rpath argument</span>&#8221;</span> is the install
 	directory of the library being built.</p>

 <p>Add <code class="varname">USE_LIBTOOL=yes</code> to the
     package Makefile. This will override the package's own libtool
     in most cases.  For older libtool using packages,  libtool is
     made by ltconfig script during the do-configure step; you can
     check the libtool script location by doing <span class="command"><strong>make
     configure; find work*/ -name libtool</strong></span>.</p>
 <p><code class="varname">LIBTOOL_OVERRIDE</code> specifies which libtool
     scripts, relative to <code class="varname">WRKSRC</code>, to override.  By
     default, it is set to <span class="quote">&#8220;<span class="quote">libtool */libtool
     */*/libtool</span>&#8221;</span>.  If this does not match the location of the
     package's libtool script(s), set it as appropriate.</p>
 <p>If you do not need <code class="filename">*.a</code> static
     libraries built and installed, then use
     <code class="varname">SHLIBTOOL_OVERRIDE</code> instead.</p>
 <p>If your package makes use of the platform-independent library

     (libltdl), you should include devel/libltdl/buildlink3.mk.</p>
 <p>Some packages use libtool incorrectly so that the package

 <p>If a package needs GNU autoconf or automake to be executed
     to regenerate the configure script and Makefile.in makefile
     templates, then they should be executed in a pre-configure
     target.</p>
 <p>For packages that need only autoconf:</p>
 <pre class="programlisting">
 AUTOCONF_REQD=  2.50            # if default version is not good enough
 USE_TOOLS+=     autoconf        # use "autoconf213" for autoconf-2.13
 ...
 pre-configure:
         cd ${WRKSRC} &amp;&amp; autoconf
 ...
 </pre>
 <p>and for packages that need automake and autoconf:</p>
 <pre class="programlisting">
 AUTOMAKE_REQD=  1.7.1           # if default version is not good enough
 USE_TOOLS+=     automake        # use "automake14" for automake-1.4

 pre-configure:

 <p>Packages which use GNU Automake will almost certainly
     require GNU Make.</p>
 <p>There are times when the configure process makes
     additional changes to the generated files, which then causes
     the build process to try to re-execute the automake sequence.
     This is prevented by touching various files in the configure
     stage. If this causes problems with your package you can set
     <code class="varname">AUTOMAKE_OVERRIDE=NO</code> in the package

 <p>The most common failures when building a package are that
 	some platforms do not provide certain header files, functions or
 	libraries, or they provide the functions in a library that the

 <a name="fixes.build.cpp"></a>19.5.1. Compiling C and C++ code conditionally</h3></div></div></div>
 <p>If a package already comes with a GNU configure script, the
 	preferred way to fix the build failure is to change the
 	configure script, not the code. In the other cases, you can
 	utilize the C preprocessor, which defines certain macros
 	depending on the operating system and hardware architecture it
 	compiles for. These macros can be queried using for example
 	<code class="varname">#if defined(__i386)</code>. Almost every operating
 	system, hardware architecture and compiler has its own macro.
 	For example, if the macros <code class="varname">__GNUC__</code>,
 	<code class="varname">__i386__</code> and <code class="varname">__NetBSD__</code>
 	are all defined, you know that you are using NetBSD on an i386
 	compatible CPU, and your compiler is GCC.</p>
 <p>The list of the following macros for hardware and
 	operating system depends on the compiler that is used. For
 	example, if you want to conditionally compile code on Solaris,
 	don't use <code class="varname">__sun__</code>, as the SunPro compiler
 	does not define it. Use <code class="varname">__sun</code> instead.</p>

 <p>Many modern packages using GNU autoconf allow to set the

     is needed because otherwise the documentation ends up in

 <p>An exception to the above is that library API documentation

 <p>Certain packages, most of them in the games category, install
     a score file that allows all users on the system to record their
     highscores.  In order for this to work, the binaries need to be
     installed setgid and the score files owned by the appropriate

     <code class="varname">GAMEDIRMODE</code>, <code class="varname">GAMES_GROUP</code>,
     <code class="varname">GAMEMODE</code>, <code class="varname">GAME_USER</code>.

     <code class="varname">GAMEDATA_PERMS</code> and
     <code class="varname">SETGID_GAMES_PERMS</code>.</p>
 <p>An example that illustrates some of the variables described above is
     <code class="filename">games/moon-buggy</code>. <code class="varname">OWN_DIRS_PERMS</code> is
     used to properly set directory permissions of the directory where the

 BUILD_DEFS+=            VARBASE

     need not be listed.</p>
 <p>A package which needs the <span class="quote">&#8220;<span class="quote">makeinfo</span>&#8221;</span> command
     at build time must add <span class="quote">&#8220;<span class="quote">makeinfo</span>&#8221;</span> to
     <code class="varname">USE_TOOLS</code> in its Makefile. If a minimum

     should be noted with the <code class="varname">TEXINFO_REQD</code>

 <p>The build and installation process of the software provided

     for them. In pkgsrc, this place is
     <code class="literal">${PREFIX}/${PKGMANDIR}</code>, and this expression
     should be used in packages. The default for
     <code class="varname">PKGMANDIR</code> is
     <span class="quote">&#8220;<span class="quote"><code class="filename">man</code></span>&#8221;</span>. Another often-used value

 <p>The support for a custom <code class="varname">PKGMANDIR</code>

 </div>
 <p>The <code class="filename">PLIST</code> files can just use
     <code class="filename">man/</code> as the top level directory for the man
     page file entries, and the pkgsrc framework will convert as
     needed. In all other places, the correct
     <code class="varname">PKGMANDIR</code> must be used.</p>
 <p>Packages that are
     configured with <code class="varname">GNU_CONFIGURE</code> set as
     <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>, by default will use the
     <code class="filename">./configure</code>
     --mandir switch to set where the man pages should be installed.
     The path is <code class="varname">GNU_CONFIGURE_MANDIR</code> which defaults
     to <code class="varname">${PREFIX}/${PKGMANDIR}</code>.</p>
 <p>Packages that use <code class="varname">GNU_CONFIGURE</code> but do not
     use --mandir, can set <code class="varname">CONFIGURE_HAS_MANDIR</code>
     to <span class="quote">&#8220;<span class="quote">no</span>&#8221;</span>.
     Or if the <code class="filename">./configure</code> script uses

 <p>Our policy is that we accept binaries only from pkgsrc
 	developers to guarantee that the packages don't contain any
 	trojan horses etc. This is not to annoy anyone but rather to
 	protect our users! You're still free to put up your home-made
 	binary packages and tell the world where to get them. NetBSD
 	developers doing bulk builds and wanting to upload them please
 	see <a class="xref" href="#bulk" title="Chapter 7. Creating binary packages for everything in pkgsrc (bulk builds)">Chapter 7, <i>Creating binary packages for everything in pkgsrc (bulk

 <p>First, check that your package is complete, compiles and
 	runs well; see <a class="xref" href="#debug" title="Chapter 20. Debugging">Chapter 20, <i>Debugging</i></a> and the rest of this
-	document. Next, generate an uuencoded gzipped <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?tar+1.i386+NetBSD-7.1"><span class="citerefentry"><span class="refentrytitle">tar</span>(1)</span></a>

 	</p>
 <p>In the form of the problem report, the category should be
 	<span class="quote">&#8220;<span class="quote">pkg</span>&#8221;</span>, the synopsis should include the package name
 	and version number, and the description field should contain a
 	short description of your package (contents of the COMMENT
 	variable or DESCR file are OK). The uuencoded package data should
 	go into the <span class="quote">&#8220;<span class="quote">fix</span>&#8221;</span> field.</p>
 <p>If you want to submit several packages, please send a
 	separate PR for each one, it's easier for us to track things
 	that way.</p>
 <p>Alternatively, you can also import new packages into
 	pkgsrc-wip (<span class="quote">&#8220;<span class="quote">pkgsrc work-in-progress</span>&#8221;</span>); see the

 <a name="general-notes-for-changes"></a>21.3. General notes when adding, updating, or removing packages</h2></div></div></div>
 <p>Please note all package additions, updates, moves, and
 	removals in <code class="filename">pkgsrc/doc/CHANGES-<em class="replaceable"><code>YYYY</code></em></code>. It's very
 	important to keep this file up to date and conforming to the
 	existing format, because it will be used by scripts to
 	automatically update pages on <a class="ulink" href="http://www.NetBSD.org/" target="_top">www.NetBSD.org</a> and other
 	sites. Additionally, check the
 	<code class="filename">pkgsrc/doc/TODO</code> file and remove the entry
 	for the package you updated or removed, in case it was mentioned
 	there.</p>
 <p>When the <code class="varname">PKGREVISION</code> of a package is
 	bumped, the change should appear in
 	<code class="filename">pkgsrc/doc/CHANGES-<em class="replaceable"><code>YYYY</code></em></code> if it is security
 	related or otherwise relevant. Mass bumps that result from a
 	dependency being updated should not be mentioned. In all other
 	cases it's the developer's decision.</p>
 <p>There is a make target that helps in creating proper
   <code class="filename">CHANGES-<em class="replaceable"><code>YYYY</code></em></code> entries:  <span class="command"><strong>make
   changes-entry</strong></span>. It uses the optional <code class="varname">CTYPE</code>
   and <code class="varname">NETBSD_LOGIN_NAME</code> variables. The general
   usage is to first make sure that your <code class="filename">CHANGES-<em class="replaceable"><code>YYYY</code></em></code>
   file is up-to-date (to avoid having to resolve conflicts later-on)
   and then to <span class="command"><strong>cd</strong></span> to the package directory.  For
   package updates, <span class="command"><strong>make changes-entry</strong></span> is enough.
   For new packages, or package moves or removals, set the
   <code class="varname">CTYPE</code> variable on the command line to "Added",
   "Moved", or "Removed".  You can set <code class="varname">NETBSD_LOGIN_NAME</code>
   in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> if your local login name is
   not the same as your NetBSD login name. The target also automatically
   removes possibly existing entries for the package in the
   <code class="filename">TODO</code> file. Don't forget to commit
   the changes, e.g. by using <span class="command"><strong>make commit-changes-entry</strong></span>!
   If you are not using a checkout directly from cvs.NetBSD.org, but e.g.
   a local copy of the repository, you can set USE_NETBSD_REPO=yes. This
   makes the cvs commands use the main repository.

 <a name="commit-messages"></a>21.4. Commit Messages</h2></div></div></div>
 <p>For several years, there have been mirrors of pkgsrc in
   fossil, git, and hg. Standard practise when using these tools is to
   make the first line of a commit message function as a summary that
   can be read without the rest, such as is commonly done with "git log
   --oneline". For this reason, we have the following guidelines for
   pkgsrc commit messages:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>Start the commit message with a line that explains the
     big picture in 65 characters or less. When a commit is for one
     package, include the name of the package. For updates, include the
     version to which it is updated.</p></li>
 <li class="listitem"><p>Leave the next line empty.</p></li>
 <li class="listitem"><p>Then come the details for the commit (changes in that
     package, reason for a change) and any relevant PRs. Wrap this
     section.</p></li>
 </ul></div>
 <p>Here is an example:
   </p>
 <pre class="programlisting">
   libxslt: update to 1.0.30
   Changes since 1.0.29:
   ...
   </pre>
 <p>
   </p>
 <p>Here is another example:
   </p>
 <pre class="programlisting">
   mk/bsd.pkg.mk: enable SSP by default on NetBSD
   (rationale)
   </pre>
 <p>
   </p>
 <p>Commit messages are final: no <span class="quote">&#8220;<span class="quote">cvs admin</span>&#8221;</span> is
   allowed on the pkgsrc repository to change commit messages.</p>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="committing-importing"></a>21.5. Committing: Adding a package to CVS</h2></div></div></div>
 <p>This section is only of interest for pkgsrc developers with write
   access to the pkgsrc repository.</p>
 <p>When the package is finished, <span class="quote">&#8220;<span class="quote">cvs add</span>&#8221;</span> the files.
 Start by adding the directory and then files in the directory. Don't
 forget to add the new package to the category's
 <code class="filename">Makefile</code>. Make sure you don't forget any files;
 you can check by running <span class="quote">&#8220;<span class="quote">cvs status</span>&#8221;</span>. An example:</p>
 <pre class="programlisting">
 <code class="prompt">$</code> cd .../pkgsrc/category
 <code class="prompt">$</code> cvs add pkgname
 <code class="prompt">$</code> cd pkgname
 <code class="prompt">$</code> cvs add DESCR Makefile PLIST distinfo buildlink3.mk patches
 <code class="prompt">$</code> cvs add patches/p*
 <code class="prompt">$</code> cvs status | less
 <code class="prompt">$</code> cvs commit
 <code class="prompt">$</code> cd ..
 <code class="prompt">$</code> vi Makefile # add SUBDIRS+=pkgname line
 <code class="prompt">$</code> cvs commit Makefile
 <code class="prompt">$</code> cd pkgname
 <code class="prompt">$</code> make CTYPE=Added commit-changes-entry
 </pre>
 <p>The commit message of the initial import should include part of the
   <code class="filename">DESCR</code> file, so people reading the mailing lists know
   what the package is/does.</p>
 <p>Also mention the new package in
 <code class="filename">pkgsrc/doc/CHANGES-20xx</code>.</p>
 <p>Previously, <span class="quote">&#8220;<span class="quote">cvs import</span>&#8221;</span> was suggested, but it was
 much easier to get wrong than <span class="quote">&#8220;<span class="quote">cvs add</span>&#8221;</span>.</p>

 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="updating-package"></a>21.6. Updating a package to a newer version</h2></div></div></div>
 <p>Please always put a concise, appropriate and relevant summary of the
   changes between old and new versions into the commit log when updating
   a package. There are various reasons for this:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>A URL is volatile, and can change over time. It may go away completely
   or its information may be overwritten by newer information.</p></li>
 <li class="listitem"><p>Having the change information between old and new versions in our CVS
   repository is very useful for people who use either cvs or anoncvs.</p></li>
 <li class="listitem"><p>Having the change information between old and new versions in our CVS
   repository is very useful for people who read the pkgsrc-changes mailing
   list, so that they can make tactical decisions about when to upgrade
   the package.</p></li>
 </ul></div>
 <p>Please also recognize that, just because a new version of a package
   has been released, it should not automatically be upgraded in the CVS
   repository.  We prefer to be conservative in the packages that are
   included in pkgsrc - development or beta packages are not really the
   best thing for most places in which pkgsrc is used. Please use your
   judgement about what should go into pkgsrc, and bear in mind that
   stability is to be preferred above new and possibly untested features.</p>

 <a name="renaming-package"></a>21.7. Renaming a package in pkgsrc</h2></div></div></div>
 <p>Renaming packages is not recommended.</p>
 <p>When renaming packages, be sure to fix any references to old name
   in other Makefiles, options, buildlink files, etc.</p>
 <p>Also When renaming a package, please define
   <code class="varname">SUPERSEDES</code> to the package name and dewey version
   pattern(s) of the previous package name.
   This may be repeated for multiple renames.
   The new package would be an exact replacement.

 <p>Note that <span class="quote">&#8220;<span class="quote">successor</span>&#8221;</span> in the
   CHANGES-<em class="replaceable"><code>YYYY</code></em> file doesn't necessarily
   mean that it <span class="emphasis"><em>supersedes</em></span>, as that successor may

 <div class="blockquote"><blockquote class="blockquote"><p>The GNOME project provides two things: The GNOME desktop
   environment, an intuitive and attractive desktop for users, and the
   GNOME development platform, an extensive framework for building
   applications that integrate into the rest of the desktop.</p></blockquote></div>
 <p>pkgsrc provides a seamless way to automatically build and install
 a complete GNOME environment <span class="emphasis"><em>under many different
 platforms</em></span>.  We can say with confidence that pkgsrc is one of
 the most advanced build and packaging systems for GNOME due to its
 included technologies buildlink3, the wrappers and tools framework and
 automatic configuration file management.  Lots of efforts are put into
 achieving a completely clean deinstallation of installed software
 components.</p>
 <p>Given that pkgsrc is <a class="ulink" href="http://www.NetBSD.org/" target="_top">NetBSD</a>'s official packaging system,
 the above also means that great efforts are put into making GNOME work
 under this operating system.  Recently, <a class="ulink" href="http://www.dragonflybsd.org/" target="_top">DragonFly BSD</a> also adopted
 pkgsrc as its preferred packaging system, contributing lots of
 portability fixes to make GNOME build and install under it.</p>
 <p>This chapter is aimed at pkgsrc developers and other people
 interested in helping our GNOME porting and packaging efforts.  It
 provides instructions on how to manage the existing packages and some
 important information regarding their internals.</p>

 <p>Almost all GNOME applications are written in C and use a common
 set of tools as their build system.  Things get different with the new
 bindings to other languages (such as Python), but the following will
 give you a general idea on the minimum required tools:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem">
 <p>Almost all GNOME applications use the GNU Autotools as their

 </li>
 <li class="listitem"><p>If the package uses intltool, be sure to add

 <li class="listitem">
 <p>If the package uses gtk-doc (a documentation generation
     utility), do <span class="emphasis"><em>not</em></span> add a dependency on it.  The
     tool is rather big and the distfile should come with pregenerated
     documentation anyway; if it does not, it is a bug that you ought to

 <p>The default location of installed HTML files
     (<code class="filename">share/gtk-doc/&lt;package-name&gt;</code>) is correct

     <span class="command"><strong>devhelp</strong></span> will not be able to open them.  You can

 <p>GNOME uses multiple <span class="emphasis"><em>shared</em></span> directories and
 files under the installation prefix to maintain databases.  In this
 context, shared means that those exact same directories and files are
 used among several different packages, leading to conflicts in the
 <code class="filename">PLIST</code>.  pkgsrc currently includes functionality to
 handle the most common cases, so you have to forget about using
 <code class="literal">@unexec ${RMDIR}</code> lines in your file lists and
 omitting shared files from them.  If you find yourself doing those,
 <span class="emphasis"><em>your package is most likely incorrect</em></span>.</p>
 <p>The following table lists the common situations that result in
 using shared directories or files.  For each of them, the appropriate
 solution is given.  After applying the solution be sure to

 <a name="full-update"></a>23.3. Updating GNOME to a newer version</h2></div></div></div>
 <p>When seeing GNOME as a whole, there are two kinds of
 updates:</p>
 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term">Major update</span></dt>
 <dd>
 <p>Given that there is still a very long way for GNOME 3 (if it
       ever appears), we consider a major update one that goes from a
       <code class="literal">2.X</code> version to a <code class="literal">2.Y</code> one,
       where <code class="literal">Y</code> is even and greater than
       <code class="literal">X</code>.  These are hard to achieve because they
       introduce lots of changes in the components' code and almost all
       GNOME distfiles are updated to newer versions.  Some of them can
       even break API and ABI compatibility with the previous major
       version series.  As a result, the update needs to be done all at
       once to minimize breakage.</p>
 <p>A major update typically consists of around 80 package
       updates and the addition of some new ones.</p>
 </dd>
 <dt><span class="term">Minor update</span></dt>
 <dd>
 <p>We consider a minor update one that goes from a
       <code class="literal">2.A.X</code> version to a <code class="literal">2.A.Y</code>
       one where <code class="literal">Y</code> is greater than
       <code class="literal">X</code>.  These are easy to achieve because they do
       not update all GNOME components, can be done in an incremental way
       and do not break API nor ABI compatibility.</p>
 <p>A minor update typically consists of around 50 package
       updates, although the numbers here may vary a lot.</p>
 </dd>
 </dl></div>
 <p>In order to update the GNOME components in pkgsrc to a new stable

 </li>
 <li class="listitem"><p>Open each meta package's <code class="filename">Makefile</code> and

 <li class="listitem">

     newer version (even if found in the FTP) because the meta packages
     are supposed to list the exact versions that form a specific GNOME

     serious issue in the overall desktop experience; these typically
     come in the form of a revision bump in pkgsrc, not in newer versions

 <a name="patching"></a>23.4. Patching guidelines</h2></div></div></div>
 <p>GNOME is a very big component in pkgsrc which approaches 100
 packages.  Please, it is very important that you always, always,
 <span class="strong"><strong>always</strong></span> feed back any portability
 fixes you do to a GNOME package to the mainstream developers (see <a class="xref" href="#components.patches.feedback" title="11.3.5. Feedback to the author">Section 11.3.5, &#8220;Feedback to the author&#8221;</a>).  This is the only way to get
 their attention on portability issues and to ensure that future versions
 can be built out-of-the box on NetBSD.  The less custom patches in
 pkgsrc, the easier further updates are.  Those developers in charge of
 issuing major GNOME updates will be grateful if you do that.</p>
 <p>The most common places to report bugs are the <a class="ulink" href="http://bugzilla.gnome.org/" target="_top">GNOME's Bugzilla</a> and the <a class="ulink" href="http://bugzilla.freedesktop.org/" target="_top">freedesktop.org's
 Bugzilla</a>.  Not all components use these to track bugs, but most
 of them do.  Do not be short on your reports: always provide detailed
 explanations of the current failure, how it can be improved to achieve
 maximum portability and, if at all possible, provide a patch against CVS
 head.  The more verbose you are, the higher chances of your patch being
 accepted.</p>
 <p>Also, please avoid using preprocessor magic to fix portability
 issues.  While the FreeBSD GNOME people are doing a great job in porting
 GNOME to their operating system, the official GNOME sources are now
 plagued by conditionals that check for <code class="varname">__FreeBSD__</code>
 and similar macros.  This hurts portability.  Please see our patching
 guidelines (<a class="xref" href="#components.patches.guidelines" title="11.3.4. Patching guidelines">Section 11.3.4, &#8220;Patching guidelines&#8221;</a>) for more
 details.</p>

 <p>The pkgsrc infrastructure consists of many small Makefile
 	fragments. Each such fragment needs a properly specified
 	interface. This chapter explains how such an interface looks
 	like.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="infr.vardef"></a>24.1. The meaning of variable definitions</h2></div></div></div>
 <p>Whenever a variable is defined in the pkgsrc
 	infrastructure, the location and the way of definition provide
 	much information about the intended use of that variable.
 	Additionally, more documentation may be found in a header
 	comment or in this pkgsrc guide.</p>
 <p>A special file is
 	<code class="filename">mk/defaults/mk.conf</code>, which lists all
 	variables that are intended to be user-defined. They are either
 	defined using the <code class="literal">?=</code> operator or they are
 	left undefined because defining them to anything would
 	effectively mean <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>. All these variables may be
 	overridden by the pkgsrc user in the <code class="varname">MAKECONF</code>
 	file.</p>
 <p>Outside this file, the following conventions apply:
 	Variables that are defined using the <code class="literal">?=</code>
 	operator may be overridden by a package.</p>
 <p>Variables that are defined using the <code class="literal">=</code>
 	operator may be used read-only at run-time.</p>
 <p>Variables whose name starts with an underscore must not be
 	accessed outside the pkgsrc infrastructure at all. They may
 	change without further notice.</p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
 <h3 class="title">Note</h3>
 <p>These conventions are currently not applied
 	consistently to the complete pkgsrc
 	infrastructure.</p>
 </div>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="infr.vardef.problems"></a>24.2. Avoiding problems before they arise</h2></div></div></div>
 <p>All variables that contain lists of things should default
 	to being empty. Two examples that do not follow this rule are
 	<code class="varname">USE_LANGUAGES</code> and
 	<code class="varname">DISTFILES</code>. These variables cannot simply be
 	modified using the <code class="literal">+=</code> operator in package
 	<code class="filename">Makefile</code>s (or other files included by
 	them), since there is no guarantee whether the variable is
 	already set or not, and what its value is. In the case of
 	<code class="varname">DISTFILES</code>, the packages <span class="quote">&#8220;<span class="quote">know</span>&#8221;</span>
 	the default value and just define it as in the following
 	example.</p>
 <pre class="programlisting">
 DISTFILES=      ${DISTNAME}${EXTRACT_SUFX} additional-files.tar.gz
 </pre>
 <p>Because of the selection of this default value, the same
 	value appears in many package Makefiles. Similarly for
 	<code class="varname">USE_LANGUAGES</code>, but in this case the default
 	value (<span class="quote">&#8220;<span class="quote"><code class="literal">c</code></span>&#8221;</span>) is so short that it
 	doesn't stand out. Nevertheless it is mentioned in many
 	files.</p>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="infr.var"></a>24.3. Variable evaluation</h2></div></div></div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.var.load"></a>24.3.1. At load time</h3></div></div></div>
 <p>Variable evaluation takes place either at load time or at
 	runtime, depending on the context in which they occur. The
 	contexts where variables are evaluated at load time are:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p>The right hand side of the <code class="literal">:=</code>
 	and <code class="literal">!=</code> operators,</p></li>
 <li class="listitem"><p>Make directives like <code class="literal">.if</code> or
 	<code class="literal">.for</code>,</p></li>
 <li class="listitem"><p>Dependency lines.</p></li>
 </ul></div>
 <p>A special exception are references to the iteration
 	variables of <code class="literal">.for</code> loops, which are expanded
 	inline, no matter in which context they appear.</p>
 <p>As the values of variables may change during load time,
 	care must be taken not to evaluate them by accident. Typical
 	examples for variables that should not be evaluated at load time
 	are <code class="varname">DEPENDS</code> and
 	<code class="varname">CONFIGURE_ARGS</code>. To make the effect more
 	clear, here is an example:</p>
 <pre class="programlisting">
 CONFIGURE_ARGS=         # none
 CFLAGS=                 -O
 CONFIGURE_ARGS+=        CFLAGS=${CFLAGS:Q}
 CONFIGURE_ARGS:=        ${CONFIGURE_ARGS}
 CFLAGS+=                -Wall
 </pre>
 <p>This code shows how the use of the <code class="literal">:=</code>
 	operator can quickly lead to unexpected results. The first
 	paragraph is fairly common code. The second paragraph evaluates
 	the <code class="varname">CONFIGURE_ARGS</code> variable, which results in
 	<code class="literal">CFLAGS=-O</code>. In the third paragraph, the
 	<code class="literal">-Wall</code> is appended to the
 	<code class="varname">CFLAGS</code>, but this addition will not appear in
 	<code class="varname">CONFIGURE_ARGS</code>. In actual code, the three
 	paragraphs from above typically occur in completely unrelated
 	files.</p>

 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.var.run"></a>24.3.2. At runtime</h3></div></div></div>
 <p>After all the files have been loaded, the values of the
 	variables cannot be changed anymore. Variables that are used in
 	the shell commands are expanded at this point.</p>

 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="infr.varspec"></a>24.4. How can variables be specified?</h2></div></div></div>
 <p>There are many ways in which the definition and use of a
 	variable can be restricted in order to detect bugs and violations
 	of the (mostly unwritten) policies. A package can be checked with
 	<code class="literal">pkglint -Wall</code> to see whether it meets these
 	rules.</p>

 <a name="infr.design.intf"></a>24.5. Designing interfaces for Makefile fragments</h2></div></div></div>
 <p>Most of the <code class="filename">.mk</code> files fall into one
 	of the following classes. Cases where a file falls into more
 	than one class should be avoided as it often leads to subtle
 	bugs.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.design.intf.proc"></a>24.5.1. Procedures with parameters</h3></div></div></div>
 <p>In a traditional imperative programming language some of
 	the <code class="filename">.mk</code> files could be described as
 	procedures. They take some input parameters and&mdash;after
 	inclusion&mdash;provide a result in output parameters. Since all
 	variables in <code class="filename">Makefile</code>s have global scope
 	care must be taken not to use parameter names that have already
 	another meaning. For example, <code class="varname">PKGNAME</code> is a
 	bad choice for a parameter name.</p>
 <p>Procedures are completely evaluated at preprocessing time.
 	That is, when calling a procedure all input parameters must be
 	completely resolvable. For example,
 	<code class="varname">CONFIGURE_ARGS</code> should never be an input
 	parameter since it is very likely that further text will be
 	added after calling the procedure, which would effectively apply
 	the procedure to only a part of the variable. Also, references
 	to other variables will be modified after calling the
 	procedure.</p>
 <p>A procedure can declare its output parameters either as
 	suitable for use in preprocessing directives or as only
 	available at runtime. The latter alternative is for variables
 	that contain references to other runtime variables.</p>
 <p>Procedures shall be written such that it is possible to
 	call the procedure more than once. That is, the file must not
 	contain multiple-inclusion guards.</p>
 <p>Examples for procedures are
 	<code class="filename">mk/bsd.options.mk</code> and
 	<code class="filename">mk/buildlink3/bsd.builtin.mk</code>. To express
 	that the parameters are evaluated at load time, they should be
 	assigned using the <code class="literal">:=</code> operator, which should
 	be used only for this purpose.</p>
 </div>

 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.design.intf.action"></a>24.5.2. Actions taken on behalf of parameters</h3></div></div></div>
 <p>Action files take some input parameters and may define
 	runtime variables. They shall not define loadtime variables.
 	There are action files that are included implicitly by the
 	pkgsrc infrastructure, while other must be included
 	explicitly.</p>
 <p>An example for action files is
 	<code class="filename">mk/subst.mk</code>.</p>

 <a name="infr.order"></a>24.6. The order in which files are loaded</h2></div></div></div>
 <p>Package <code class="filename">Makefile</code>s usually consist of
 	a set of variable definitions, and include the file
 	<code class="filename">../../mk/bsd.pkg.mk</code> in the very last line.
 	Before that, they may also include various other
 	<code class="filename">*.mk</code> files if they need to query the
 	availability of certain features like the type of compiler or
 	the X11 implementation. Due to the heavy use of preprocessor
 	directives like <code class="literal">.if</code> and
 	<code class="literal">.for</code>, the order in which the files are loaded
 	matters.</p>
 <p>This section describes at which point the various files
 	are loaded and gives reasons for that order.</p>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.order.prefs"></a>24.6.1. The order in <code class="filename">bsd.prefs.mk</code>
 </h3></div></div></div>
 <p>The very first action in <code class="filename">bsd.prefs.mk</code>
 	is to define some essential variables like
 	<code class="varname">OPSYS</code>, <code class="varname">OS_VERSION</code> and
 	<code class="varname">MACHINE_ARCH</code>.</p>
 <p>Then, the user settings are loaded from the file specified
 	in <code class="varname">MAKECONF</code>, which is usually <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.
 	After that, those variables
 	that have not been overridden by the user are loaded from
 	<code class="filename">mk/defaults/mk.conf</code>.</p>
 <p>After the user settings, the system settings and platform
 	settings are loaded, which may override the user
 	settings.</p>
 <p>Then, the tool definitions are loaded. The tool wrappers
 	are not yet in effect. This only happens when building a
 	package, so the proper variables must be used instead of the
 	direct tool names.</p>
 <p>As the last steps, some essential variables from the
 	wrapper and the package system flavor are loaded, as well as the
 	variables that have been cached in earlier phases of a package
 	build.</p>
 </div>
 <div class="sect2">
 <div class="titlepage"><div><div><h3 class="title">
 <a name="infr.order.pkg"></a>24.6.2. The order in <code class="filename">bsd.pkg.mk</code>
 </h3></div></div></div>
 <p>First, <code class="filename">bsd.prefs.mk</code> is loaded.</p>
 <p>Then, the various <code class="filename">*-vars.mk</code> files are
 	loaded, which fill default values for those variables that have
 	not been defined by the package. These variables may later
 	be used even in unrelated files.</p>
 <p>Then, the file <code class="filename">bsd.pkg.error.mk</code>
 	provides the target <code class="literal">error-check</code> that is added
 	as a special dependency to all other targets that use
 	<code class="varname">DELAYED_ERROR_MSG</code> or
 	<code class="varname">DELAYED_WARNING_MSG</code>.</p>
 <p>Then, the package-specific hacks from
 	<code class="filename">hacks.mk</code> are included.</p>
 <p>Then, various other files follow. Most of them don't have
 	any dependencies on what they need to have included before or
 	after them, though some do.</p>
 <p>The code to check <code class="varname">PKG_FAIL_REASON</code> and
 	<code class="varname">PKG_SKIP_REASON</code> is then executed, which
 	restricts the use of these variables to all the files that have
 	been included before. Appearances in later files will be
 	silently ignored.</p>
 <p>Then, the files for the main targets are included, in the
 	order of later execution, though the actual order should not
 	matter.</p>
 <p>At last, some more files are included that don't set any
 	interesting variables but rather just define make targets to be
 	executed.</p>

 <p>The pkgsrc infrastructure consists of a large codebase,
 	and there are many corners where every little bit of a file is
 	well thought out, making pkgsrc likely to fail as soon as
 	anything is changed near those parts. To prevent most changes
 	from breaking anything, a suite of regression tests should go
 	along with every important part of the pkgsrc infrastructure.
 	This chapter describes how regression tests work in pkgsrc and
 	how you can add new tests.</p>

 <p>Every directory in the <code class="filename">regress</code>
 	category that contains a file called <code class="filename">spec</code>
 	is considered a regression test. This file is a shell program

 <div class="titlepage"><div><div><h3 class="title">

 <p>These functions do not take any parameters. Although they
 	are called in <span class="quote">&#8220;<span class="quote">set -e</span>&#8221;</span> mode, they don't stop at the
 	first failing command. See <a class="ulink" href="http://stackoverflow.com/q/4072984" target="_top">this StackOverflow

 <p>This function runs the actual test. By default,

 <p>When defining this function, make sure that all output that

 </div>
 <p>The pkgsrc system has already been ported to many
 	operating systems, hardware architectures and compilers. This
 	chapter explains the necessary steps to make pkgsrc even more
 	portable.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="porting.opsys"></a>26.1. Porting pkgsrc to a new operating system</h2></div></div></div>
 <p>To port pkgsrc to a new operating system (called
 	<code class="literal">MyOS</code> in this example), you need to touch the
 	following files:</p>
 <div class="variablelist"><dl class="variablelist">
 <dt><span class="term"><code class="filename">pkgtools/bootstrap-mk-files/files/mods/<em class="replaceable"><code>MyOS</code></em>.sys.mk</code></span></dt>
 <dd><p>This file contains some basic definitions, for
 	example the name of the C
 	compiler.</p></dd>
 <dt><span class="term"><code class="filename">mk/bsd.prefs.mk</code></span></dt>
 <dd><p>Insert code that defines the variables
 	<code class="varname">OPSYS</code>, <code class="varname">OS_VERSION</code>,
 	<code class="varname">LOWER_OS_VERSION</code>,
 	<code class="varname">LOWER_VENDOR</code>,
 	<code class="varname">MACHINE_ARCH</code>, <code class="varname">OBJECT_FMT</code>,
 	<code class="varname">APPEND_ELF</code>, and the other variables that
 	appear in this file.</p></dd>
 <dt><span class="term"><code class="filename">mk/platform/<em class="replaceable"><code>MyOS</code></em>.mk</code></span></dt>
 <dd><p>This file contains the platform-specific
 	definitions that are used by pkgsrc. Start by copying one of the
 	other files and edit it to your
 	needs.</p></dd>
 <dt><span class="term"><code class="filename">mk/tools/tools.<em class="replaceable"><code>MyOS</code></em>.mk</code></span></dt>
 <dd><p>This file defines the paths to all the tools
 	that are needed by one or the other package in pkgsrc, as well
 	as by pkgsrc itself. Find out where these tools are on your
 	platform and add them.</p></dd>
 </dl></div>
 <p>Now, you should be able to build some basic packages, like
-	<a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/perl5/README.html" target="_top"><code class="filename">lang/perl5</code></a>, <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/shells/bash/README.html" target="_top"><code class="filename">shells/bash</code></a>.</p>

 </div>
 <p>As in other big projects, the directory layout of pkgsrc
 	is quite complex for newbies. This chapter explains where you
 	find things on the FTP server. The base directory on
 	<code class="filename">ftp.NetBSD.org</code> is <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/" target="_top"><code class="filename">/pub/pkgsrc/</code></a>.
 	On other servers it may be different, but inside this directory,
 	everything should look the same, no matter on which server you
 	are. This directory contains some subdirectories, which are
 	explained below.</p>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="ftp-distfiles"></a>C.1. <code class="filename">distfiles</code>: The distributed source files</h2></div></div></div>
 <p>The directory <code class="filename">distfiles</code> contains lots
 	of archive files from all pkgsrc packages, which are mirrored
 	here. The subdirectories are called after their package names
 	and are used when the distributed files have names that don't
 	explicitly contain a version number or are otherwise too generic
 	(for example <code class="filename">release.tar.gz</code>).</p>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="ftp-misc"></a>C.2. <code class="filename">misc</code>: Miscellaneous things</h2></div></div></div>
 <p>This directory contains things that individual pkgsrc
 	developers find worth publishing.</p>
 </div>
 <div class="sect1">
 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="ftp-packages"></a>C.3. <code class="filename">packages</code>: Binary packages</h2></div></div></div>
 <p>This directory contains binary packages for the various
 	platforms that are supported by pkgsrc.
 	Each subdirectory is of the form <em class="replaceable"><code>OPSYS</code></em>/<em class="replaceable"><code>ARCH</code></em>/<em class="replaceable"><code>OSVERSION_TAG</code></em>. The meaning of these variables is:</p>
 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
 <li class="listitem"><p><code class="varname">OPSYS</code> is the name of the
 	operating system for which the packages have been built. The
 	name is taken from the output of the <span class="command"><strong>uname</strong></span>
 	command, so it may differ from the one you are used to
 	hear.</p></li>
 <li class="listitem"><p><code class="varname">ARCH</code> is the hardware
 	architecture of the platform for which the packages have been
 	built. It also includes the <code class="varname">ABI</code> (Application
 	Binary Interface) for platforms that have several of
 	them.</p></li>
 <li class="listitem"><p><code class="varname">OSVERSION</code> is the version of
 	the operating system. For version numbers that change often (for
 	example NetBSD-current), the often-changing part should be
 	replaced with an <code class="literal">x</code>, for example
 	<code class="literal">4.99.x</code>.</p></li>
 <li class="listitem"><p><code class="varname">TAG</code> is either
 	<code class="literal">20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>
 	for a stable branch, or <code class="literal">head</code> for packages
 	built from the HEAD branch. The latter should only be used when
 	the packages are updated on a regular basis. Otherwise the date
 	from checking out pkgsrc should be appended, for example
 	<code class="literal">head_20071015</code>.</p></li>
 </ul></div>
 <p>The rationale for exactly this scheme is that the pkgsrc users looking for binary packages
 	can quickly click through the directories on the
 	server and find the best binary packages for their machines. Since they
 	usually know the operating system and the hardware architecture, OPSYS
 	and ARCH are placed first. After these choices, they can select the
 	best combination of OSVERSION and TAG together, since it is usually the
 	case that packages stay compatible between different version of the
 	operating system.</p>
 <p>In each of these directories, there is a
 	whole binary packages collection for a specific platform. It has a directory called
 	<code class="filename">All</code> which contains all binary packages.
 	Besides that, there are various category directories that
 	contain symbolic links to the real binary packages.</p>

 <div class="titlepage"><div><div><h2 class="title" style="clear: both">
 <a name="ftp-reports"></a>C.4. <code class="filename">reports</code>: Bulk build reports</h2></div></div></div>
 <p>Here are the reports from bulk builds, for those who want
 	to fix packages that didn't build on some of the platforms. The
 	structure of subdirectories should look like the one in <a class="xref" href="#ftp-packages" title="C.3. packages: Binary packages">Section C.3, &#8220;<code class="filename">packages</code>: Binary packages&#8221;</a>.</p>

 <code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>:
 source packages</h2></div></div></div>
 <p>These directories contain the <span class="quote">&#8220;<span class="quote">real</span>&#8221;</span> pkgsrc,
 	that is the files that define how to create binary packages from
 	source archives.</p>
 <p>The directory <code class="filename">pkgsrc</code> contains a
 	snapshot of the CVS repository, which is updated regularly. The
 	file <code class="filename">pkgsrc.tar.gz</code> contains the same as the
 	directory, ready to be downloaded as a whole.</p>
 <p>In the directories for the quarterly branches, there is an
 	additional file called
 	<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em>.tar.gz</code>,
 	which contains the state of pkgsrc when it was branched.</p>

 <p>The procedure to edit the pkgsrc guide is:</p>
 <div class="procedure"><ol class="procedure" type="1">
 <li class="step"><p>Make sure you have the packages needed to
 	regenerate the pkgsrc guide (and other XML-based NetBSD
 	documentation) installed. These are automatically installed when
-	you install the <a href="http://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/pkgsrc-guide-tools/README.html" target="_top"><code class="filename">meta-pkgs/pkgsrc-guide-tools</code></a> package.</p></li>
+	you install the <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/pkgsrc-guide-tools/README.html" target="_top"><code class="filename">meta-pkgs/pkgsrc-guide-tools</code></a> package.</p></li>
 <li class="step"><p>Run <span class="command"><strong>cd doc/guide</strong></span> to get to the
 	right directory. All further steps will take place
 	here.</p></li>
 <li class="step"><p>Edit the XML file(s) in
 	<code class="filename">files/</code>.</p></li>
 <li class="step"><p>Run <span class="command"><strong>bmake</strong></span> to check the pkgsrc
 	guide for valid XML and to build the final output files. If you
 	get any errors at this stage, you can just edit the files, as
 	there are only symbolic links in the working directory, pointing
 	to the files in <code class="filename">files/</code>.</p></li>
 <li class="step"><p><span class="command"><strong>(cd files &amp;&amp; cvs
 	commit)</strong></span></p></li>
 <li class="step"><p>Run <span class="command"><strong>bmake clean &amp;&amp; bmake</strong></span> to
 	regenerate the output files with the proper RCS
 	Ids.</p></li>
 <li class="step">
 <p>Run <span class="command"><strong>bmake regen</strong></span> to install and
 	commit the files in both <code class="filename">pkgsrc/doc</code> and
 	<code class="filename">htdocs</code>.</p>
 <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">

 <p>If you have added, removed or renamed some chapters,
 	you need to synchronize them using <span class="command"><strong>cvs add</strong></span> or
 	<span class="command"><strong>cvs delete</strong></span> in the htdocs
 	directory.</p>
