 .Sh NAME
+.
 .Nm BUILDING
 .Nd Procedure for building
 .Nx
 from source code.
+.
 .Sh REQUIREMENTS
+.
 .Nx
 is designed to be buildable on most POSIX-compliant host systems.
 The basic build procedure is the same whether compiling
 .Em natively
 (on the same
 .Nx
 architecture) or
 .Em cross compiling
 (on another architecture or OS).
 .Pp
 This source tree contains a special subtree,
 .Dq tools ,
 which uses the host system to create a build toolchain for the target
 architecture.
 The host system must have at least C and C++
 compilers in order to create the toolchain
 .Nm ( make
 is not required); all other tools are created as part of the
 .Nx
 build process.
 (See the environment variables section below if you need
 to override or manually select your compilers.)
+.
 .Sh FILES
+.
 .Ss Source tree layout
+.
 .Bl -tag -width "BUILDING.mdoc"
 .It Sy doc/BUILDING.mdoc
 This document (in -mdoc troff format; the original copy).
 .It Sy BUILDING
 This document (in plaintext).
 .It Sy tools/compat/README
 Special notes for cross-hosting a NetBSD build on non-NetBSD platforms.
 .It Sy Makefile
 The main Makefile for
 .Nx ;
 should only be run for native builds with an appropriately up-to-date
 version of
 .Nx
 .Xr make 1 .
 (For building from out-of-date systems or on a non-native host, see the
 .Nm build.sh
 shell script.)
 .It Sy UPDATING
 Special notes for updating from an earlier revision of
 .Nx .
 It is important to read this file before every build of an updated
 source tree.
 .It Sy build.sh
 Bourne-compatible shell script used for building the host build tools
 and the
 .Nx
 system from scratch.
 Can be used for both native and cross builds, and should be used instead of
 .Xr make 1
 for any source tree that is updated and recompiled regularly.
 .It Sy crypto/dist/ , dist/ , gnu/dist/
 Sources imported verbatim from third parties, without mangling the
 existing build structure.
 Other source trees in
 .Sy bin
 through
 .Sy usr.sbin
 use the
 .Nx
 .Xr make 1
 .Dq reachover
 Makefile semantics when building these programs for a native host.
 .It Sy distrib/ , etc/
 Sources for items used when making a full release snapshot, such as
 files installed in
 .Sy DESTDIR Ns Pa /etc
 on the destination system, boot media, and release notes.
 .It Sy tests/ , regress/
 Regression test harness.
 Can be cross-compiled, but only run natively.
 .Pa tests/
 uses the
 .Xr atf 7
 test framework;
 .Pa regress/
 contains older tests that have not yet been migrated to
 .Xr atf 7 .
 .It Sy sys/
 .Nx
 kernel sources.
 .It Sy tools/
 .Dq Reachover
 build structure for the host build tools.
 This has a special method of determining out-of-date status.
 .It Sy bin/ ... usr.sbin/
 Sources to the
 .Nx
 userland (non-kernel) programs.
 If any of these directories are missing, they will be skipped during the build.
 .It Sy x11/
 .Dq Reachover
 build structure for X11R6; the source is in
 .Sy X11SRCDIR .
 .El
+.
 .Ss Build tree layout
+.
 The
 .Nx
 build tree is described in
 .Xr hier 7 ,
 and the release layout is described in
 .Xr release 7 .
 .Pp
+.
 .Sh CONFIGURATION
+.
 .Ss Environment variables
 ..
 Several environment variables control the behaviour of
 .Nx
 builds.
+.
 .Bl -tag -width "MAKEOBJDIRPREFIX"
+.
+.
 .It Sy HOST_SH
 Path name to a shell available on the host system
 and suitable for use during the build.
 The
 .Nx
 build system requires a modern Bourne-like shell
 with POSIX-compliant features,
 and also requires support for the
 .Dq local
 keyword to declare local variables in shell functions
 (which is a widely-implemented but non-standardised feature).
 .Pp
 Depending on the host system, a suitable shell may be
 .Pa /bin/sh ,
 .Pa /usr/xpg4/bin/sh ,
 .Pa /bin/ksh
 (provided it is a variant of ksh that supports the
 .Dq local
 keyword,
 such as ksh88, but not ksh93),
 or
 .Pa /usr/local/bin/bash .
 .Pp
 Most parts of the build require
 .Sy HOST_SH
 to be an absolute path; however,
 .Nm build.sh
 allows it to be a simple command name, which will be converted
 to an absolute path by searching the
 .Sy PATH .
+.
 .It Sy HOST_CC
 Path name to C compiler used to create the toolchain.
+.
 .It Sy HOST_CXX
 Path name to C++ compiler used to create the toolchain.
+.
 .It Sy MACHINE
 Machine type, e.g.,
 .Dq macppc .
+.
 .It Sy MACHINE_ARCH
 Machine architecture, e.g.,
 .Dq powerpc .
+.
 .It Sy MAKE
 Path name to invoke
 .Xr make 1
 as.
+.
 .It Sy MAKEFLAGS
 Flags to invoke
 .Xr make 1
 with.
 Note that
 .Sy build.sh
 ignores the value of
 .Sy MAKEFLAGS
 passed in the environment, but allows
 .Sy MAKEFLAGS
 to be set via the
 .Fl V
 option.
+.
 .It Sy MAKEOBJDIR
 Directory to use as the
 .Sy .OBJDIR
 for the current directory.
 The value is subjected to variable expansion by
 .Xr make 1 .
 Typical usage is to set this variable to a value involving the use of
 .Sq ${.CURDIR:S...}
 or
 .Sq ${.CURDIR:C...} ,
 to derive the value of
 .Sy .OBJDIR
 from the value of
 .Sy .CURDIR .
 Used only if
 .Sy MAKEOBJDIRPREFIX
 is not defined.
 .Sy MAKEOBJDIR
 can be provided only in the environment or via the
 .Fl O
 flag of
 .Nm build.sh ;
 it cannot usefully be set inside a Makefile, including
 .Pa mk.conf
 or
 .Sy ${MAKECONF} .
+.
 .It Sy MAKEOBJDIRPREFIX
 Top level directory of the object directory tree.
 The value is subjected to variable expansion by
 .Xr make 1 .
 .Sy build.sh
 will create the
 ${MAKEOBJDIRPREFIX}
 directory if necessary, but if
 .Xr make 1
 is used without
 .Sy build.sh ,
 then rules in
 .Aq bsd.obj.mk
 will abort the build if the
 ${MAKEOBJDIRPREFIX}
 directory does not exist.
 If the value is defined and valid, then
 ${MAKEOBJDIRPREFIX}/${.CURDIR}
 is used as the
 .Sy .OBJDIR
 for the current directory.
 The current directory may be read only.
 .Sy MAKEOBJDIRPREFIX
 can be provided only in the environment or via the
 .Fl M
 flag of
 .Nm build.sh ;
 it cannot usefully be set inside a Makefile, including
 .Pa mk.conf
 or
 .Sy ${MAKECONF} .
+.
 .El
+.
 .Ss \*qmake\*q variables
+.
 .de YorN
 Can be set to
 .Dq yes
 or
 .Dq no .
 ..
 .de DFLT
 .Pp
 .Em Default :
 ..
 .de DFLTu
 .DFLT
 Unset.
 ..
 .de DFLTy
 .DFLT
 .Dq yes
 ..
 .de DFLTn
 .DFLT
 .Dq no
 ..
 Several variables control the behavior of
 .Nx
 builds.
 Unless otherwise specified, these variables may be set in
 either the process environment or the
 .Xr make 1
 configuration file specified by
 .Sy MAKECONF .
+.
 .Bl -tag -width "MKCATPAGES"
+.
 .It Sy BUILDID
 Identifier for the build.
 The identifier will be appended to
 object directory names, and can be consulted in the
 .Xr make 1
 configuration file in order to set additional build parameters,
 such as compiler flags.
+.
 .It Sy BUILDSEED
 GCC uses random numbers when compiling C++ code.
 This variable seeds the gcc random number generator using
 the -frandom-seed flag with this value.
 By default, it is set to NetBSD-(majorversion).
 Using a fixed value causes C++ binaries to be the same when
 built from the same sources, resulting in identical (reproducible) builds.
 Additional information is available in the GCC
 documentation of -frandom-seed.
+.
 .It Sy DESTDIR
 Directory to contain the built
 .Nx
 system.
 If set, special options are passed to the compilation tools to
 prevent their default use of the host system's
 .Sy /usr/include , /usr/lib ,
 and so forth.
 This pathname must be an absolute path, and should
 .Em not
 end with a slash
 .Pq /
 character.
 (For installation into the system's root directory, set
 .Sy DESTDIR
 to an empty string, not to
 .Dq / ) .
 The directory must reside on a file system which supports long file
 names and hard links.
 .DFLT
 Empty string if
 .Sy USETOOLS
 is
 .Dq yes ;
 unset otherwise.
 .Pp
 .Em Note :
 .Sy build.sh
 will provide a default of
 .Pa destdir. Ns Sy MACHINE
 (in the top-level
 .Sy .OBJDIR )
 unless run in
 .Sq expert
 mode.
+.
 .It Sy MAKECONF
 The name of the
 .Xr make 1
 configuration file.
 .Em Only settable in the process environment.
 .DFLT
 .Dq /etc/mk.conf
+.
 .It Sy MAKEVERBOSE
 Level of verbosity of status messages.
 Supported values:
 .Bl -tag -width xxx
 .It 0
 No descriptive messages or commands executed by
 .Xr make 1
 are shown.
 .It 1
 Brief messages are shown describing what is being done,
 but the actual commands executed by
 .Xr make 1
 are not displayed.
 .It 2
 Descriptive messages are shown as above (prefixed with a
 .Sq # ) ,
 and ordinary commands performed by
 .Xr make 1
 are displayed.
 .It 3
 In addition to the above, all commands performed by
 .Xr make 1
 are displayed, even if they would ordinarily have been hidden
 through use of the
 .Dq \&@
 prefix in the relevant makefile.
 .It 4
 In addition to the above, commands executed by
 .Xr make 1
 are traced through use of the
 .Xr sh 1
 .Dq Fl x
 flag.
 .El
 .DFLT
+.
 .It Sy MKCATPAGES
 .YorN
 Indicates whether preformatted plaintext manual pages will be created
 during a build.
 .DFLTy
+.
 .It Sy MKCRYPTO
 .YorN
 Indicates whether cryptographic code will be included in a build;
 provided for the benefit of countries that do not allow strong
 cryptography.
 Will not affect use of the standard low-security password encryption system,
 .Xr crypt 3 .
 .DFLTy
+.
 .It Sy MKDOC
 .YorN
 Indicates whether system documentation destined for
 .Sy DESTDIR Ns Pa /usr/share/doc
 will be installed during a build.
 .DFLTy
+.
 .It Sy MKHTML
 .YorN
 Indicates whether preformatted HTML manual pages will be built
 and installed
 .DFLTy
+.
 .It Sy MKHOSTOBJ
 .YorN
 If set to
 .Dq yes ,
 then for programs intended to be run on the compile host,
 the name, release, and architecture of the host operating system
 will be suffixed to the name of the object directory created by
 .Dq make obj .
 (This allows multiple host systems to compile NetBSD for a single target.)
 If set to
 .Dq no ,
 then programs built to be run on the compile host will use the same
 object directory names as programs built to be run on the target.
 .DFLTn
+.
 .It Sy MKINFO
 .YorN
 Indicates whether GNU Info files, used for the documentation for
 most of the compilation tools, will be created and installed during a
 build.
 .DFLTy
+.
 .It Sy MKKMOD
 .YorN
 Indicates whether kernel modules are built and installed.
 .DFLTy
+.
 .It Sy MKLINT
 .YorN
 Indicates whether
 .Xr lint 1
 will be run against portions of the
 .Nx
 source code during the build, and whether lint libraries will be
 installed into
 .Sy DESTDIR Ns Pa /usr/libdata/lint .
 .DFLTy
+.
 .It Sy MKMAN
 .YorN
 Indicates whether manual pages will be installed during a build.
 .DFLTy
+.
 .It Sy MKNLS
 .YorN
 Indicates whether Native Language System locale zone files will be
 compiled and installed during a build.
 .DFLTy
+.
 .It Sy MKOBJ
 .YorN
 Indicates whether object directories will be created when running
 .Dq make obj .
 If set to
 .Dq no ,
 then all built files will be located inside the regular source tree.
 .DFLTy
 .Pp
 Note that setting
 .Sy MKOBJ
 to
 .Dq no
 is not recommended and may cause problems when updating the tree with
 .Xr cvs 1 .
+.
 .It Sy MKPIC
 .YorN
 Indicates whether shared objects and libraries will be created and
 installed during a build.
 If set to
 .Dq no ,
 the entire built system will be statically linked.
 .DFLT
 Platform dependent.
 As of this writing, all platforms except
 .Sy sh3
 default to
 .Dq yes .
+.
 .It Sy MKPICINSTALL
 .YorN
 Indicates whether the
 .Xr ar 1
 format libraries
 .Sy ( lib*_pic.a ) ,
 used to generate shared libraries, are installed during a build.
 .DFLTy
+.
 .It Sy MKPROFILE
 .YorN
 Indicates whether profiled libraries
 .Sy ( lib*_p.a )
 will be built and installed during a build.
 .DFLT
 .Dq yes ;
 however, some platforms turn off
 .Sy MKPROFILE
 by default at times due to toolchain problems with profiled code.
+.
 .It Sy MKREPRO
 .YorN
 Create reproducable builds.
 This enables different switches to make two builds from the same
 source tree result in the same build results.
 .DFLTn
+.
 .It Sy MKSHARE
 .YorN
 Indicates whether files destined to reside in
 .Sy DESTDIR Ns Pa /usr/share
 will be built and installed during a build.
 If set to
 .Dq no ,
 then all of
 .Sy MKCATPAGES , MKDOC , MKINFO , MKMAN ,
 and
 .Sy MKNLS
 will be set to
 .Dq no
 unconditionally.
 .DFLTy
+.
 .It Sy MKSTRIPIDENT
 .YorN
-Indicates whether program binaries and shared libraries should be built
+Indicates whether RCS IDs, for use with
-to include RCS IDs for use with
+.Xr ident 1 ,
-.Xr ident 1 .
+should be stripped from program binaries and shared libraries.
 .DFLTn
+.
 .It Sy MKUNPRIVED
 .YorN
 Indicates whether an unprivileged install will occur.
 The user, group, permissions, and file flags, will not be set on
 the installed items; instead the information will be appended to
 a file called
 .Pa METALOG
 in
 .Sy DESTDIR .
 The contents of
 .Pa METALOG
 are used during the generation of the distribution tar files to ensure
 that the appropriate file ownership is stored.
 .DFLTn
+.
 .It Sy MKUPDATE
 .YorN
 Indicates whether all install operations intended to write to
 .Sy DESTDIR
 will compare file timestamps before installing, and skip the install
 phase if the destination files are up-to-date.
 This also has implications on full builds (see next subsection).
 .DFLTn
+.
 .It Sy MKX11
 .YorN
 Indicates whether X11 is built from
 .Sy X11SRCDIR .
 .DFLTn
+.
 .It Sy TOOLDIR
 Directory to hold the host tools, once built.
 If specified, must be an absolute path.
 This directory should be unique to a given host system and
 .Nx
 source tree.
 (However, multiple targets may share the same
 .Sy TOOLDIR ;
 the target-dependent files have unique names.)  If unset, a default based
 on the
 .Xr uname 1
 information of the host platform will be created in the
 .Sy .OBJDIR
 of
 .Pa src .
 .DFLTu
+.
 .It Sy USETOOLS
 Indicates whether the tools specified by
 .Sy TOOLDIR
 should be used as part of a build in progress.
 Must be set to
 .Dq yes
 if cross-compiling.
 .Bl -tag -width "never"
 .It Sy yes
 Use the tools from
 .Sy TOOLDIR .
 .It Sy no
 Do not use the tools from
 .Sy TOOLDIR ,
 but refuse to build native compilation tool components that are
 version-specific for that tool.
 .It Sy never
 Do not use the tools from
 .Sy TOOLDIR ,
 even when building native tool components.
 This is similar to the traditional
 .Nx
 build method, but does
 .Em not
 verify that the compilation tools in use are up-to-date enough in order
 to build the tree successfully.
 This may cause build or runtime problems when building the whole
 .Nx
 source tree.
 .El
 .DFLT
 .Dq yes ,
 unless
 .Sy TOOLCHAIN_MISSING
 is set to
 .Dq yes .
 .Pp
 .Sy USETOOLS
 is also set to
 .Dq no
 when using
 .Aq bsd.*.mk
 outside the
 .Nx
 source tree.
+.
 .It Sy X11SRCDIR
 Directory containing the X11R6 source.
 If specified, must be an absolute path.
 The main X11R6 source is found in
 .Sy X11SRCDIR Ns Pa /xfree/xc .
 .DFLT
 .Sy NETBSDRCDIR Ns Pa /../xsrc ,
 if that exists; otherwise
 .Pa /usr/xsrc .
+.
 .It Sy X11FLAVOUR
 The style of X11 cross-built, set to either
 .Dq Xorg
 or
 .Dq XFree86 .
 .DFLT
 .Dq Xorg
 on amd64, i386, macppc, shark and sparc64 platforms,
 .Dq XFree86
 on everything else.
+.
 .El
+.
 .Ss \*qmake\*q variables for full builds
 These variables only affect the top level
 .Dq Makefile
 and do not affect manually building subtrees of the
 .Nx
 source code.
+.
 .Bl -tag -width "INSTALLWORLDDIR"
+.
 .It Sy INSTALLWORLDDIR
 Location for the
 .Dq make installworld
 target to install to.
 If specified, must be an absolute path.
 .DFLT
 .Dq /
+.
 .It Sy MKOBJDIRS
 .YorN
 Indicates whether object directories will be created automatically
 (via a
 .Dq make obj
 pass) at the start of a build.
 .DFLTn
 .Pp
 If using
 .Sy build.sh ,
 the default is
 .Dq yes .
 This may be set back to
 .Dq no
 by giving
 .Sy build.sh
 the
 .Fl o
 option.
+.
 .It Sy MKUPDATE
 .YorN
 If set, then in addition to the effects described for
 .Sy MKUPDATE=yes
 above, this implies the effects of
 .Sy NOCLEANDIR
 (i.e.,
 .Dq make cleandir
 is avoided).
 .DFLTn
 .Pp
 If using
 .Sy build.sh ,
 this may be set by giving the
 .Fl u
 option.
+.
 .It Sy NBUILDJOBS
 Now obsolete.
 Use the
 .Xr make 1
 option
 .Fl j ,
 instead.
 See below.
 .DFLTu
+.
 .It Sy NOCLEANDIR
 If set, avoids the
 .Dq make cleandir
 phase of a full build.
 This has the effect of allowing only changed
 files in a source tree to be recompiled.
 This can speed up builds when updating only a few files in the tree.
 .DFLTu
 .Pp
 See also
 .Sy MKUPDATE .
+.
 .It Sy NODISTRIBDIRS
 If set, avoids the
 .Dq make distrib-dirs
 phase of a full build.
 This skips running
 .Xr mtree 8
 on
 .Sy DESTDIR ,
 useful on systems where building as an unprivileged user, or where it is
 known that the system-wide mtree files have not changed.
 .DFLTu
+.
 .It Sy NOINCLUDES
 If set, avoids the
 .Dq make includes
 phase of a full build.
 This has the effect of preventing
 .Xr make 1
 from thinking that some programs are out-of-date simply because the
 system include files have changed.
 However, this option should not be used when updating the entire
 .Nx
 source tree arbitrarily; it is suggested to use
 .Sy MKUPDATE=yes
 instead in that case.
 .DFLTu
+.
 .It Sy RELEASEDIR
 If set, specifies the directory to which a
 .Xr release 7
 layout will be written at the end of a
 .Dq make release .
 If specified, must be an absolute path.
 .DFLTu
 .Pp
 .Em Note :
 .Sy build.sh
 will provide a default of
 .Pa releasedir
 (in the top-level
 .Sy .OBJDIR )
 unless run in
 .Sq expert
 mode.
+.
 .El
+.
 .Sh BUILDING
+.
 .Ss \*qmake\*q command line options
 This is not a summary of all the options available to
 .Xr make 1 ;
 only the options used most frequently with
 .Nx
 builds are listed here.
+.
 .Bl -tag -width "var=value"
+.
 .It Fl j Ar njob
 Run up to
 .Ar njob
 .Xr make 1
 subjobs in parallel.
 Makefiles should use .WAIT or have explicit dependencies
 as necessary to enforce build ordering.
+.
 .It Fl m Ar dir
 Specify the default directory for searching for system Makefile
 segments, mainly the
 .Aq bsd.*.mk
 files.
 When building any full
 .Nx
 source tree, this should be set to the
 .Dq share/mk
 directory in the source tree.
 This is set automatically when building from the top level, or when using
 .Sy build.sh .
+.
 .It Fl n
 Display the commands that would have been executed, but do not
 actually execute them.
 This will still cause recursion to take place.
+.
 .It Fl V Ar var
 Print
 .Xr make 1 Ns 's
 idea of the value of
 .Ar var .
 Does not build any targets.
+.
 .It Em var=value
 Set the variable
 .Em var
 to
 .Em value ,
 overriding any setting specified by the process environment, the
 .Sy MAKECONF
 configuration file, or the system Makefile segments.
+.
 .El
+.
 .Ss \*qmake\*q targets
+.
 These default targets may be built by running
 .Xr make 1
 in any subtree of the
 .Nx
 source code.
 It is recommended that none of these be used from the top
 level Makefile; as a specific exception,
 .Dq make obj
 and
 .Dq make cleandir
 are useful in that context.
+.
 .Bl -tag -width "dependall"
+.
 .It Sy all
 Build programs, libraries, and preformatted documentation.
+.
 .It Sy clean
 Remove program and library object code files.
+.
 .It Sy cleandir
 Same as
 .Sy clean ,
 but also remove preformatted documentation, dependency files generated
 by
 .Dq make depend ,
 and any other files known to be created at build time.
+.
 .It Sy depend
 Create dependency files
 .Sy ( .depend )
 containing more detailed information about the dependencies of source
 code on header files.
 Allows programs to be recompiled automatically when a dependency changes.
+.
 .It Sy dependall
 Does a
 .Dq make depend
 immediately followed by a
 .Dq make all .
 This improves cache locality of the build since both passes read the source
 files in their entirety.
+.
 .It Sy distclean
 Synonym for
 .Sy cleandir .
+.
 .It Sy includes
 Build and install system header files.
 Typically needed before any system libraries or programs can be built.
+.
 .It Sy install
 Install programs, libraries, and documentation into
 .Sy DESTDIR .
 Few files will be installed to
 .Sy DESTDIR Ns Pa /dev ,
 .Sy DESTDIR Ns Pa /etc ,
 .Sy DESTDIR Ns Pa /root
 or
 .Sy DESTDIR Ns Pa /var
 in order to prevent user supplied configuration data from being overwritten.
 .It Sy lint
 Run
 .Xr lint 1
 against the C source code, where appropriate, and generate
 system-installed lint libraries.
+.
 .It Sy obj
 Create object directories to be used for built files, instead of
 building directly in the source tree.
+.
 .It Sy tags
 Create
 .Xr ctags 1
 searchable function lists usable by the
 .Xr ex 1
 and
 .Xr vi 1
 text editors.
+.
 .El
+.
 .Ss \*qmake\*q targets for the top level
+.
 Additional
 .Xr make 1
 targets are usable specifically from the top source level to facilitate
 building the entire
 .Nx
 source tree.
+.
 .Bl -tag -width "distribution"
+.
 .It Sy build
 Build the entire
 .Nx
 system (except the kernel).
 This orders portions of the source tree such that prerequisites
 will be built in the proper order.
+.
 .It Sy distribution
 Do a
 .Dq make build ,
 and then install a full distribution (which does not include a kernel) into
 .Sy DESTDIR ,
 including files in
 .Sy DESTDIR Ns Pa /dev ,
 .Sy DESTDIR Ns Pa /etc ,
 .Sy DESTDIR Ns Pa /root
 and
 .Sy DESTDIR Ns Pa /var .
+.
 .It Sy buildworld
 As per
 .Dq make distribution ,
 except that it ensures that
 .Sy DESTDIR
 is not the root directory.
+.
 .It Sy installworld
 Install the distribution from
 .Sy DESTDIR
 to
 .Sy INSTALLWORLDDIR ,
 which defaults to the root directory.
 Ensures that
 .Sy INSTALLWORLDDIR
 is not the root directory if cross compiling.
 .Pp
 The
 .Sy INSTALLSETS
 environment variable may be set to a space-separated list of
 distribution sets to be installed.
 By default, all sets except
 .Dq etc
 and
 .Dq xetc
 are installed, so most files in
 .Sy INSTALLWORLDDIR Ns Pa /etc
 will not be installed or modified.
 .Pp
 .Em Note :
 Before performing this operation with
 .Sy INSTALLWORLDDIR Ns = Ns Pa / ,
 it is highly recommended that you upgrade your kernel and reboot.
 After performing this operation,
 it is recommended that you use
 .Xr etcupdate 8
 to update files in
 .Sy INSTALLWORLDDIR Ns Pa /etc
 and that you use
 .Xr postinstall 8
 to check for inconsistencies (and possibly to fix them).
 .It Sy sets
 Create distribution sets from
 .Sy DESTDIR
 into
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /binary/sets .
 Should be run after
 .Dq make distribution ,
 as
 .Dq make build
 alone does not install all of the required files.
+.
 .It Sy sourcesets
 Create source sets of the source tree into
 .Sy RELEASEDIR Ns Pa /source/sets .
+.
 .It Sy syspkgs
 Create syspkgs from
 .Sy DESTDIR
 into
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /binary/syspkgs .
 Should be run after
 .Dq make distribution ,
 as
 .Dq make build
 alone does not install all of the required files.
+.
 .It Sy release
 Do a
 .Dq make distribution ,
 build kernels, distribution media, and install sets
 (this as per
 .Dq make sets ) ,
 and
 then package the system into a standard release layout as described by
 .Xr release 7 .
 This requires that
 .Sy RELEASEDIR
 be set (see above).
+.
 .It Sy iso-image
 Create a
 .Nx
 installation CD-ROM image in the
 .Sy RELEASEDIR Ns Pa /iso
 directory.
 The CD-ROM file system will have a layout as described in
 .Xr release 7 .
 .Pp
 For most machine types, the CD-ROM will be bootable, and will automatically
 run the
 .Xr sysinst 8
 menu-based installation program, which can be used to install or upgrade a
 .Nx
 system.
 Bootable CD-ROMs also contain tools that may be useful in
 repairing a damaged
 .Nx
 installation.
 .Pp
 Before
 .Dq make iso-image
 is attempted, RELEASEDIR must be populated by
 .Dq make release
 or equivalent.
 .Pp
 Note that other, smaller, CD-ROM images may be created in the
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /installation/cdrom
 directory by
 .Dq "make release" .
 These smaller images usually contain the same tools as the larger images in
 .Sy RELEASEDIR Ns Pa /iso ,
 but do not contain additional content such as the distribution sets.
 .Pp
 Note that the mac68k port still uses an older method of creating
 CD-ROM images.
 This requires the
 .Xr mkisofs 1
 utility, which is not part of
 .Nx ,
 but which can be installed from
 .Pa pkgsrc/sysutils/cdrtools .
+.
 .It Sy iso-image-source
 Create a
 .Nx
 installation CD-ROM image in the
 .Sy RELEASEDIR Ns Pa /iso
 directory.
 The CD-ROM file system will have a layout as described in
 .Xr release 7 .
 It will have top level directories for the machine type and source.
 .Pp
 For most machine types, the CD-ROM will be bootable, and will automatically
 run the
 .Xr sysinst 8
 menu-based installation program, which can be used to install or upgrade a
 .Nx
 system.
 Bootable CD-ROMs also contain tools that may be useful in
 repairing a damaged
 .Nx
 installation.
 .Pp
 Before
 .Dq make iso-image-source
 is attempted, RELEASEDIR must be populated by
 .Dq make sourcesets release
 or equivalent.
 .Pp
 Note that other, smaller, CD-ROM images may be created in the
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /installation/cdrom
 directory by
 .Dq make release .
 These smaller images usually contain the same tools as the larger images in
 .Sy RELEASEDIR Ns Pa /iso ,
 but do not contain additional content such as the distribution sets.
 .Pp
 Note that the mac68k port still uses an older method of creating
 CD-ROM images.
 This requires the
 .Xr mkisofs 1
 utility, which is not part of
 .Nx ,
 but which can be installed from
 .Pa pkgsrc/sysutils/cdrtools .
+.
 .It Sy install-image
 Create a bootable
 .Nx
 installation disk image in the
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /installation/installimage
 directory.
 The installation disk image is suitable for copying to
 bootable USB flash memory sticks, etc., for machines which
 are able to boot from such devices.
 The file system in the bootable disk image will have a layout
 as described in
 .Xr release 7 .
 .Pp
 The installation image is bootable, and will automatically
 run the
 .Xr sysinst 8
 menu-based installation program, which can be used to install or upgrade a
 .Nx
 system.
 The image also contains tools that may be
 useful in repairing a damaged
 .Nx
 installation.
 .Pp
 Before
 .Dq make install-image
 is attempted,
 .Sy RELEASEDIR
 must be populated by
 .Dq make release
 or equivalent.
 The build must have been performed with
 .Sy MKUNPRIVED=yes
 because
 .Dq make install-image
 relies on information in
 .Sy DESTDIR Ns Pa /METALOG .
+.
 .It live-image
 Create
 .Nx
 live images in the
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /installation/liveimage
 directory.
 The live image contains all necessary files
 to boot
 .Nx
 up to multi-user mode, including all files
 which should be extracted during installation,
 .Nx
 disklabel, bootloaders, etc.
 .Pp
 The live image is suitable for use as a disk image in
 virtual machine environments such as QEMU,
 and also useful to boot
 .Nx
 from a USB flash memory stick
 on a real machine, without the need for installation.
 .Pp
 Before
 .Dq make live-image
 is attempted, RELEASEDIR must be populated by
 .Dq make release
 or equivalent.
 The build must have been performed with
 .Sy MKUNPRIVED=yes
 because
 .Dq make install-image
 relies on information in
 .Sy DESTDIR Ns Pa /METALOG .
+.
 .It Sy regression-tests
 Can only be run after building the regression tests in the directory
 .Dq regress .
 Runs those compiled regression tests on the local host.
 Note that most tests are now managed instead using
 .Xr atf 7 ;
 this target should probably run those as well but currently does not.
+.
 .El
+.
 .Ss The \*qbuild.sh\*q script
+.
 This script file is a shell script designed to build the
 entire
 .Nx
 system on any host with a suitable modern shell and some common
 utilities.
 The required shell features are described under the
 .Sy HOST_SH
 variable.
 .Pp
 If a host system's default shell does support the required
 features, then we suggest that you explicitly specify
 a suitable shell using a command like
 .Bd -unfilled -offset indent
 .Li /path/to/suitable/shell build.sh Op Ar options
 .Ed
 .Pp
 The above command will usually enable
 .Nm build.sh
 to automatically set
 .Sy HOST_SH Ns Cm = Ns Pa /path/to/suitable/shell ,
 but if that fails, then the following set of commands may be used instead:
 .Bd -unfilled -offset indent
 .Li HOST_SH= Ns Va /path/to/suitable/shell
 .Li export HOST_SH
 .Li ${HOST_SH} build.sh Op Ar options
 .Ed
 .Pp
 If
 .Sy build.sh
 detects that it is being executed under an unsuitable shell, it attempts
 to exec a suitable shell instead, or prints an error message.
 If
 .Sy HOST_SH
 is not set explicitly, then
 .Nm build.sh
 sets a default using heuristics dependent on the host platform,
 or from the shell under which
 .Nm build.sh
 is executed (if that can be determined),
 or using the first copy of
 .Pa sh
 found in
 .Sy PATH .
 .Pp
 All cross-compile builds, and most native builds, of the entire system
 should make use of
 .Sy build.sh
 rather than just running
 .Dq make .
 This way, the
 .Xr make 1
 program will be bootstrapped properly, in case the host system has an
 older or incompatible
 .Dq make
 program.
 .Pp
 When compiling the entire system via
 .Sy build.sh ,
 many
 .Xr make 1
 variables are set for you in order to help encapsulate the build
 process.
 In the list of options below, variables that are automatically set by
 .Sy build.sh
 are noted where applicable.
+.
 .Pp
 The following operations are supported by
 .Sy build.sh :
+.
 .Bl -tag -width "distribution"
+.
 .It Sy build
 Build the system as per
 .Dq make build .
 Before the main part of the build commences, this command runs the
 .Sy obj
 operation (unless the
 .Fl o
 option is given),
 .Dq make cleandir
 (unless the
 .Fl u
 option is given),
 and the
 .Sy tools
 operation.
+.
 .It Sy distribution
 Build a full distribution as per
 .Dq make distribution .
 This command first runs the
 .Sy build
 operation.
+.
 .It Sy release
 Build a full release as per
 .Dq make release .
 This command first runs the
 .Sy distribution
 operation.
+.
 .It Sy makewrapper
 Create the
 .Sy \*[toolprefix]make-MACHINE
 wrapper.
 This operation is automatically performed for any of the other
 operations.
+.
 .It Sy cleandir
 Perform
 .Dq make cleandir .
+.
 .It Sy obj
 Perform
 .Dq make obj .
+.
 .It Sy tools
 Build and install the host tools from
 .Pa src/tools .
 This command will first run
 .Dq make obj
 and
 .Dq make cleandir
 in the
 .Pa tools
 subdirectory unless the
 .Fl o
 or
 .Fl u
 options (respectively) are given.
+.
 .It Sy install Ns = Ns Ar idir
 Install the contents of
 .Sy DESTDIR
 to
 .Ar idir ,
 using
 .Dq make installworld .
 Note that files that are part of the
 .Dq etc
 or
 .Dq xetc
 sets will not be installed, unless overridden by
 the INSTALLSETS environment variable.
+.
 .It Sy kernel Ns = Ns Ar kconf
 Build a new kernel.
 The
 .Ar kconf
 argument is the name of a configuration file suitable
 for use by
 .Xr config 1 .
 If
 .Ar kconf
 does not contain any
 .Sq /
 characters, the configuration file is expected to be found in the
 .Sy KERNCONFDIR
 directory, which is typically
 .Sy sys/arch/MACHINE/conf .
 The new kernel will be built in a subdirectory of
 .Sy KERNOBJDIR ,
 which is typically
 .Sy sys/arch/MACHINE/compile
 or an associated object directory.
 .Pp
 This command does
 .Em not
 imply the
 .Sy tools
 command; run the
 .Sy tools
 command first unless it is
 .Em certain
 that the tools already exist and are up to date.
 .Pp
 This command will run
 .Dq make cleandir
 on the kernel in question first unless the
 .Fl u
 option is given.
+.
 .It Sy modules
 This command will build kernel modules and install them into
 .Sy DESTDIR .
+.
 .It Sy releasekernel Ns = Ns Ar kconf
 Install a
 .Xr gzip 1 Ns ed
 copy of the kernel previously built by
 .Sy kernel Ns = Ns Ar kconf
 into
 .Sy RELEASEDIR/RELEASEMACHINEDIR Ns Pa /binary/kernel ,
 usually as
 .Pa netbsd- Ns Ar kconf Ns Pa .gz ,
 although the
 .Dq Pa netbsd
 prefix is determined from the
 .Dq Sy config
 directives in
 .Ar kconf .
+.
 .It Sy sets
 Perform
 .Dq make sets .
+.
 .It Sy sourcesets
 Perform
 .Dq make sourcesets .
+.
 .It Sy syspkgs
 Perform
 .Dq make syspkgs .
+.
 .It Sy iso-image
 Perform
 .Dq make iso-image .
+.
 .It Sy iso-image-source
 Perform
 .Dq make iso-image-source .
+.
 .It Sy install-image
 Perform
 .Dq make install-image .
+.
 .It Sy live-image
 Perform
 .Dq make live-image .
+.
 .El
+.
 .Pp
 The following command line options alter the behaviour of the
 .Sy build.sh
 operations described above:
+.
 .Bl -tag -width "-T tools"
+.
 .It Fl a Ar arch
 Set the value of
 .Sy MACHINE_ARCH
 to
 .Ar arch .
+.
 .It Fl B Ar buildid
 Set the value of
 .Sy BUILDID
 to
 .Ar buildid .
 This will also append the build identifier to the name of the
 .Dq make
 wrapper script so that the resulting name is of the form
 .Dq Sy \*[toolprefix]make-MACHINE-BUILDID .
+.
 .It Fl C Ar cdextras
 Append
 .Ar cdextras
 to the
 .Sy CDEXTRA
 variable,
 which is a space-separated list of files or directories that will be
 added to the CD-ROM image that may be create by the
 .Dq iso-image
 or
 .Dq iso-image-source
 operations.
 Files will be added to the root of the CD-ROM image, whereas directories
 will be copied recursively.
 If relative paths are specified, they will be converted to
 absolute paths before being used.
 Multiple paths may be specified via multiple
 .Fl C
 options, or via a single option whose argument contains multiple
 space-separated paths.
+.
 .It Fl D Ar dest
 Set the value of
 .Sy DESTDIR
 to
 .Ar dest .
 If a relative path is specified, it will be converted to an
 absolute path before being used.
+.
 .It Fl E
 Set
 .Sq expert
 mode.
 This overrides various sanity checks, and allows:
 .Sy DESTDIR
 does not have to be set to a non-root path for builds,
 and
 .Sy MKUNPRIVED=yes
 does not have to be set when building as a non-root user.
 .Pp
 .Em Note :
 It is highly recommended that you know what you are doing when
 you use this option.
+.
 .It Fl h
 Print a help message.
+.
 .It Fl j Ar njob
 Run up to
 .Ar njob
 .Xr make 1
 subjobs in parallel;
 passed through to
 .Xr make 1 .
 If you see failures for reasons other than running out of memory
 while using
 .Sy build.sh
 with
 .Fl j ,
 please save complete build logs
 so the failures can be analyzed.
 .Pp
 To achieve the fastest builds,
 .Fl j
 values between (1 + the number of CPUs) and (2 * the number of CPUs)
 are recommended.
 Use lower values on machines with limited memory or I/O bandwidth.
+.
 .It Fl M Ar obj
 Set
 .Sy MAKEOBJDIRPREFIX
 to
 .Ar obj .
 Unsets
 .Sy MAKEOBJDIR .
 See
 .Dq Fl O obj
 for more information.
 .Pp
 For instance, if the source directory is
 .Pa /usr/src ,
 a setting of
 .Dq Fl M Pa /usr/obj

 .It Sy BUILD
 If defined,
 .Sq "make install"
 checks that the targets in the source directories are up-to-date and
 re-makes them if they are out of date, instead of blindly trying to install
 out of date or non-existent targets.
 .DFLTu
+.
 .It Sy BUILDID
 Identifier for the build.
 The identifier will be appended to
 object directory names, and can be consulted in the
 .Xr make 1
 configuration file in order to set additional build parameters,
 such as compiler flags.

 should be used for
 compiler flags that select CPU-related options.
 Also note that
 .Sy CFLAGS
 should never be set in
 .Nm .
+.
 .It Sy CPUFLAGS
 Additional flags passed to the compiler/assembler to select
 CPU instruction set options, CPU tuning options, etc.
 Such options should not be specified in
 .Sy COPTS ,
 because some parts of the build process need to override
 CPU-related compiler options.
+.
 .It Sy DESTDIR
 Directory to contain the built
 .Nx
 system.
 If set, special options are passed to the compilation tools to
 prevent their default use of the host system's
 .Sy /usr/include , /usr/lib ,

 but refuse to build native compilation tool components that are
 version-specific for that tool.
 .It Sy never
 Do not use the tools from
 .Sy TOOLDIR ,
 even when building native tool components.
 This is similar to the traditional
 .Nx
 build method, but does
 .Em not
 verify that the compilation tools in use are up-to-date enough in order
 to build the tree successfully.
 This may cause build or runtime problems when building the whole
 .Nx
 source tree.
