BUILDING(8) NetBSD System Manager's Manual BUILDING(8)
NAME
BUILDING -- Procedure for building NetBSD from source code.
REQUIREMENTS
NetBSD is designed to be buildable on most POSIX-compliant host systems.
The basic build procedure is the same whether compiling natively (on the
same NetBSD architecture) or cross compiling (on another architecture or
OS).
This source tree contains a special subtree, ``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 (make is not required); all other tools are created as part of
the NetBSD build process. (See the environment variables section below
if you need to override or manually select your compilers.)

NetBSD platforms.
2003-09-29 11:58:01 +04:00
Makefile The main Makefile for NetBSD; should only be run for
native builds with an appropriately up-to-date version of
NetBSD make(1). (For building from out-of-date systems or
on a non-native host, see the build.sh shell script.)
UPDATING Special notes for updating from an earlier revision of
NetBSD. It is important to read this file before every
build of an updated source tree.
build.sh Bourne-compatible shell script used for building the host
build tools and the NetBSD system from scratch. Can be
used for both native and cross builds, and should be used
instead of make(1) for any source tree that is updated and
recompiled regularly.
crypto/dist/, dist/, gnu/dist/
Sources imported verbatim from third parties, without man-
gling the existing build structure. Other source trees in
bin through usr.sbin use the NetBSD make(1) ``reachover''
2003-09-29 11:58:01 +04:00
Makefile semantics when building these programs for a
native host.
distrib/, etc/
Sources for items used when making a full release snap-
shot, such as files installed in DESTDIR/etc on the desti-
nation system, boot media, and release notes.
tests/, regress/
Regression test harness. Can be cross-compiled, but only
run natively. tests/ uses the atf(7) test framework;
regress/ contains older tests that have not yet been
migrated to atf(7).
sys/ NetBSD kernel sources.
tools/ ``Reachover'' build structure for the host build tools.
This has a special method of determining out-of-date sta-
tus.
bin/ ... usr.sbin/
Sources to the NetBSD userland (non-kernel) programs. If
any of these directories are missing, they will be skipped
during the build.
x11/ ``Reachover'' build structure for X11R6; the source is in
X11SRCDIR.
Build tree layout
The NetBSD build tree is described in hier(7), and the release layout is
described in release(7).
CONFIGURATION
Environment variables
Several environment variables control the behaviour of NetBSD builds.
HOST_SH Path name to a POSIX-compliant shell. If this is not
set explicitly, then the default is set using heuris-
tics dependent on the host platform, or from the shell
under which build.sh is executed (if that can be deter-
mined), or using the first copy of sh found in PATH.
If the host system's /bin/sh is not POSIX-compliant, we
suggest that you build using commands like
HOST_SH=/path/to/working/shell
export HOST_SH
${HOST_SH} build.sh [options]
HOST_CC Path name to C compiler used to create the toolchain.
HOST_CXX Path name to C++ compiler used to create the toolchain.
MACHINE Machine type, e.g., ``macppc''.
MACHINE_ARCH Machine architecture, e.g., ``powerpc''.
MAKE Path name to invoke make(1) as.
MAKEFLAGS Flags to invoke make(1) with.
MAKEOBJDIR Directory to use as the .OBJDIR for the current direc-
tory. The value is subjected to variable expansion by
make(1). Typical usage is to set this variable to a
value involving the use of `${.CURDIR:S...}' or
`${.CURDIR:C...}', to derive the value of .OBJDIR from
the value of .CURDIR. Used only if MAKEOBJDIRPREFIX is
not defined. MAKEOBJDIR can be provided only in the
environment or via the -O flag of build.sh; it cannot
usefully be set inside a Makefile.
MAKEOBJDIRPREFIX Top level directory of the object directory tree. If
specified, must be an absolute path. If this is
defined, ${MAKEOBJDIRPREFIX}/${.CURDIR} is used as the
.OBJDIR for the current directory. The current direc-
tory may be read only. MAKEOBJDIRPREFIX can be pro-
vided only in the environment or via the -M flag of
build.sh; it cannot usefully be set inside a Makefile.
"make" variables
Several variables control the behavior of NetBSD builds. Unless other-
wise specified, these variables may be set in either the process environ-
ment or the make(1) configuration file specified by MAKECONF.
BUILDID Identifier for the build. The identifier will be appended to
object directory names, and can be consulted in the make(1)
configuration file in order to set additional build parame-
ters, such as compiler flags.
BUILDSEED GCC uses random numbers when compiling C++ code. This vari-
able seeds the gcc random number generator using the -fran-
dom-seed flag with this value. By default, it is set to
NetBSD-(majorversion). Using a fixed value causes C++ bina-
ries to be the same when built from the same sources. Addi-
tional information is available in the GCC documentation of
-frandom-seed.
DESTDIR Directory to contain the built NetBSD system. If set, spe-
cial options are passed to the compilation tools to prevent
their default use of the host system's /usr/include,
/usr/lib, and so forth. This pathname must be an absolute
path, and should not end with a slash (/) character. (For
installation into the system's root directory, set DESTDIR to
an empty string, not to ``/''). The directory must reside on
a file system which supports long file names and hard links.
Default: Empty string if USETOOLS is ``yes''; unset other-
wise.
Note: build.sh will provide a default of destdir.MACHINE (in
the top-level .OBJDIR) unless run in `expert' mode.
MAKECONF The name of the make(1) configuration file. Only settable in
the process environment.
Default: ``/etc/mk.conf''
MAKEVERBOSE
Level of verbosity of status messages. Supported values:
0 No descriptive messages are shown.
1 Descriptive messages are shown.
2 Descriptive messages (prefixed with a `#') and command
output is not suppressed.
Default: 2
MKCATPAGES Can be set to ``yes'' or ``no''. Indicates whether prefor-
matted plaintext manual pages will be created during a build.
Default: ``yes''
MKCRYPTO Can be set to ``yes'' or ``no''. Indicates whether crypto-
graphic code will be included in a build; provided for the
benefit of countries that do not allow strong cryptography.
2003-09-29 11:58:01 +04:00
Will not affect use of the standard low-security password
encryption system, crypt(3).
Default: ``yes''
MKDOC Can be set to ``yes'' or ``no''. Indicates whether system
2003-09-29 11:58:01 +04:00
documentation destined for DESTDIR/usr/share/doc will be
installed during a build.
Default: ``yes''
2008-09-07 03:23:17 +04:00
MKHTML Can be set to ``yes'' or ``no''. Indicates whether prefor-
matted HTML manual pages will be built and installed
Default: ``yes''
MKHOSTOBJ Can be set to ``yes'' or ``no''. If set to ``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
``make obj''. (This allows multiple host systems to compile
NetBSD for a single target.) If set to ``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.
Default: ``no''
MKINFO Can be set to ``yes'' or ``no''. Indicates whether GNU Info
files, used for the documentation for most of the compilation
tools, will be created and installed during a build.
Default: ``yes''
MKLINT Can be set to ``yes'' or ``no''. Indicates whether lint(1)
will be run against portions of the NetBSD source code during
the build, and whether lint libraries will be installed into
DESTDIR/usr/libdata/lint.
Default: ``yes''
MKMAN Can be set to ``yes'' or ``no''. Indicates whether manual
pages will be installed during a build.
Default: ``yes''
MKNLS Can be set to ``yes'' or ``no''. Indicates whether Native
2003-09-29 11:58:01 +04:00
Language System locale zone files will be compiled and
installed during a build.
Default: ``yes''
MKOBJ Can be set to ``yes'' or ``no''. Indicates whether object
directories will be created when running ``make obj''. If
set to ``no'', then all built files will be located inside
the regular source tree.
Default: ``yes''
Note that setting MKOBJ to ``no'' is not recommended and may
cause problems when updating the tree with cvs(1).
MKPIC Can be set to ``yes'' or ``no''. Indicates whether shared
objects and libraries will be created and installed during a
build. If set to ``no'', the entire built system will be
statically linked.
Default: Platform dependent. As of this writing, all plat-
forms except sh3 default to ``yes''.
MKPICINSTALL
Can be set to ``yes'' or ``no''. Indicates whether the ar(1)
2003-09-29 11:58:01 +04:00
format libraries (lib*_pic.a), used to generate shared
libraries, are installed during a build.
Default: ``yes''
MKPROFILE Can be set to ``yes'' or ``no''. Indicates whether profiled
libraries (lib*_p.a) will be built and installed during a
build.
Default: ``yes''; however, some platforms turn off MKPROFILE
by default at times due to toolchain problems with profiled
code.
MKSHARE Can be set to ``yes'' or ``no''. Indicates whether files
2003-09-29 11:58:01 +04:00
destined to reside in DESTDIR/usr/share will be built and
installed during a build. If set to ``no'', then all of
MKCATPAGES, MKDOC, MKINFO, MKMAN, and MKNLS will be set to
``no'' unconditionally.
Default: ``yes''
MKSTRIPIDENT
Can be set to ``yes'' or ``no''. Indicates whether program
binaries and shared libraries should be built to include RCS
IDs for use with ident(1).
Default: ``no''
2004-03-19 15:34:39 +03:00
MKTTINTERP Can be set to ``yes'' or ``no''. For X builds, decides if
the TrueType bytecode interpreter is turned on. See
http://www.freetype.org/patents.html for details.
Default: ``no''
2003-09-29 11:58:01 +04:00
MKUNPRIVED Can be set to ``yes'' or ``no''. Indicates whether an
unprivileged install will occur. The user, group, permis-
sions, and file flags, will not be set on the installed
items; instead the information will be appended to a file
called METALOG in DESTDIR. The contents of METALOG are used
during the generation of the distribution tar files to ensure
that the appropriate file ownership is stored.
Default: ``no''
2003-09-29 11:58:01 +04:00
MKUPDATE Can be set to ``yes'' or ``no''. Indicates whether all
install operations intended to write to DESTDIR will compare
file timestamps before installing, and skip the install phase
2003-09-29 11:58:01 +04:00
if the destination files are up-to-date. This also has
implications on full builds (see next subsection).
Default: ``no''
MKX11 Can be set to ``yes'' or ``no''. Indicates whether X11R6 is
built from X11SRCDIR.
Mutually exclusive to MKXORG != no.
Default: ``no''
MKXORG Can be set to ``yes'' or ``no''. Indicates whether X11R7
(modular Xorg) is built from X11SRCDIR.
Mutually exclusive to MKX11 != no.
Default: ``no''
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 NetBSD source tree. (However, multi-
ple targets may share the same TOOLDIR; the target-dependent
files have unique names.) If unset, a default based on the
uname(1) information of the host platform will be created in
the .OBJDIR of src.
Default: Unset.
USETOOLS Indicates whether the tools specified by TOOLDIR should be
used as part of a build in progress. Must be set to ``yes''
if cross-compiling.
yes Use the tools from TOOLDIR.
no Do not use the tools from TOOLDIR, but refuse to build
native compilation tool components that are version-
specific for that tool.
never Do not use the tools from TOOLDIR, even when building
native tool components. This is similar to the tradi-
tional NetBSD build method, but does 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
NetBSD source tree.
Default: ``yes'', unless TOOLCHAIN_MISSING is set to ``yes''.
USETOOLS is also set to ``no'' when using <bsd.*.mk> outside
the NetBSD source tree.
X11SRCDIR Directory containing the X11R6 source. If specified, must be
an absolute path. The main X11R6 source is found in
X11SRCDIR/xfree/xc.
Default: ``/usr/xsrc''
"make" variables for full builds
These variables only affect the top level ``Makefile'' and do not affect
manually building subtrees of the NetBSD source code.
INSTALLWORLDDIR Location for the ``make installworld'' target to install
to. If specified, must be an absolute path.
Default: ``/''
2003-09-29 11:58:01 +04:00
MKOBJDIRS Can be set to ``yes'' or ``no''. Indicates whether
object directories will be created automatically (via a
``make obj'' pass) at the start of a build.
Default: ``no''
If using build.sh, the default is ``yes''. This may be
set back to ``no'' by giving build.sh the -o option.
MKUPDATE Can be set to ``yes'' or ``no''. If set, then in addi-
tion to the effects described for MKUPDATE=yes above,
this implies the effects of NOCLEANDIR (i.e., ``make
cleandir'' is avoided).
Default: ``no''
If using build.sh, this may be set by giving the -u
option.
NBUILDJOBS Now obsolete. Use the make(1) option -j, instead. See
below.
Default: Unset.
NOCLEANDIR If set, avoids the ``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.
Default: Unset.
See also MKUPDATE.
NODISTRIBDIRS If set, avoids the ``make distrib-dirs'' phase of a full
build. This skips running mtree(8) on DESTDIR, useful
on systems where building as an unprivileged user, or
where it is known that the system-wide mtree files have
not changed.
Default: Unset.
NOINCLUDES If set, avoids the ``make includes'' phase of a full
build. This has the effect of preventing make(1) from
2003-09-29 11:58:01 +04:00
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
NetBSD source tree arbitrarily; it is suggested to use
MKUPDATE=yes instead in that case.
Default: Unset.
RELEASEDIR If set, specifies the directory to which a release(7)
layout will be written at the end of a ``make release''.
If specified, must be an absolute path.
Default: Unset.
Note: build.sh will provide a default of releasedir (in
the top-level .OBJDIR) unless run in `expert' mode.
BUILDING
"make" command line options
This is not a summary of all the options available to make(1); only the
options used most frequently with NetBSD builds are listed here.
2002-05-03 02:14:12 +04:00
-j njob Run up to njob make(1) subjobs in parallel. Makefiles should
use .WAIT or have explicit dependencies as necessary to
enforce build ordering.
2002-05-03 02:14:12 +04:00
-m dir Specify the default directory for searching for system Make-
file segments, mainly the <bsd.*.mk> files. When building any
full NetBSD source tree, this should be set to the
``share/mk'' directory in the source tree. This is set auto-
matically when building from the top level, or when using
build.sh.
-n Display the commands that would have been executed, but do not
actually execute them. This will still cause recursion to
take place.
-V var Print make(1)'s idea of the value of var. Does not build any
targets.
var=value Set the variable var to value, overriding any setting speci-
fied by the process environment, the MAKECONF configuration
file, or the system Makefile segments.
"make" targets
These default targets may be built by running make(1) in any subtree of
the NetBSD source code. It is recommended that none of these be used
from the top level Makefile; as a specific exception, ``make obj'' and
``make cleandir'' are useful in that context.
all Build programs, libraries, and preformatted documentation.
clean Remove program and library object code files.
2003-09-29 11:58:01 +04:00
cleandir Same as clean, but also remove preformatted documentation,
dependency files generated by ``make depend'', and any other
files known to be created at build time.
2003-09-29 11:58:01 +04:00
depend Create dependency files (.depend) containing more detailed
information about the dependencies of source code on header
files. Allows programs to be recompiled automatically when a
dependency changes.
dependall Does a ``make depend'' immediately followed by a ``make all''.
2002-05-03 02:14:12 +04:00
This improves cache locality of the build since both passes
read the source files in their entirety.
distclean Synonym for cleandir.
2003-09-29 11:58:01 +04:00
includes Build and install system header files. Typically needed
before any system libraries or programs can be built.
install Install programs, libraries, and documentation into DESTDIR.
Few files will be installed to DESTDIR/dev, DESTDIR/etc,
DESTDIR/root or DESTDIR/var in order to prevent user supplied
configuration data from being overwritten.
lint Run lint(1) against the C source code, where appropriate, and
generate system-installed lint libraries.
obj Create object directories to be used for built files, instead
of building directly in the source tree.
tags Create ctags(1) searchable function lists usable by the ex(1)
and vi(1) text editors.
"make" targets for the top level
Additional make(1) targets are usable specifically from the top source
level to facilitate building the entire NetBSD source tree.
build Build the entire NetBSD system (except the kernel). This
orders portions of the source tree such that prerequisites
will be built in the proper order.
distribution Do a ``make build'', and then install a full distribution
(which does not include a kernel) into DESTDIR, including
files in DESTDIR/dev, DESTDIR/etc, DESTDIR/root and
DESTDIR/var.
buildworld As per ``make distribution'', except that it ensures that
DESTDIR is not the root directory.
installworld Install the distribution from DESTDIR to INSTALLWORLDDIR,
which defaults to the root directory. Ensures that
INSTALLWORLDDIR is not the root directory if cross compil-
ing.
The INSTALLSETS environment variable may be set to a list
of distribution sets to be installed. By default, all sets
except ``etc'' and ``xetc'' are installed, so most files in
INSTALLWORLDDIR/etc will not be installed or modified.
Note: Before performing this operation with
INSTALLWORLDDIR=/, it is highly recommended that you
upgrade your kernel and reboot. After performing this
operation, it is recommended that you use etcupdate(8) to
update files in INSTALLWORLDDIR/etc and that you use
postinstall(8) to check for inconsistencies (and possibly
to fix them).
sets Create distribution sets from DESTDIR into
RELEASEDIR/RELEASEMACHINEDIR/binary/sets. Should be run
after ``make distribution'', as ``make build'' alone does
not install all of the required files.
sourcesets Create source sets of the source tree into
RELEASEDIR/source/sets.
syspkgs Create syspkgs from DESTDIR into
RELEASEDIR/RELEASEMACHINEDIR/binary/syspkgs. Should be run
after ``make distribution'', as ``make build'' alone does
not install all of the required files.
2003-09-29 11:58:01 +04:00
release Do a ``make distribution'', build kernels, distribution
media, and install sets (this as per ``make sets''), and
then package the system into a standard release layout as
described by release(7). This requires that RELEASEDIR be
set (see above).
iso-image Create a NetBSD installation CD-ROM image in the
RELEASEDIR/iso directory. The CD-ROM file system will have
a layout as described in release(7).
For most machine types, the CD-ROM will be bootable, and
will automatically run the sysinst(8) menu-based installa-
tion program, which can be used to install or upgrade a
NetBSD system. Bootable CD-ROMs also contain tools that
may be useful in repairing a damaged NetBSD installation.
Before ``make iso-image'' is attempted, RELEASEDIR must be
populated by ``make release'' or equivalent.
Note that other, smaller, CD-ROM images may be created in
the RELEASEDIR/RELEASEMACHINEDIR/installation/cdrom direc-
tory by ``make release''. These smaller images usually
contain the same tools as the larger images in
RELEASEDIR/iso, but do not contain additional content such
as the distribution sets.
Note that the mac68k port still uses an older method of
creating CD-ROM images. This requires the mkisofs(1) util-
ity, which is not part of NetBSD, but which can be
installed from pkgsrc/sysutils/cdrtools.
2007-08-30 14:29:02 +04:00
iso-image-source
Create a NetBSD installation CD-ROM image in the
RELEASEDIR/iso directory. The CD-ROM file system will have
a layout as described in release(7). It will have top
level directories for the machine type and source.
For most machine types, the CD-ROM will be bootable, and
will automatically run the sysinst(8) menu-based installa-
tion program, which can be used to install or upgrade a
NetBSD system. Bootable CD-ROMs also contain tools that
may be useful in repairing a damaged NetBSD installation.
Before ``make iso-image-source'' is attempted, RELEASEDIR
must be populated by ``make sourcesets release'' or equiva-
lent.
Note that other, smaller, CD-ROM images may be created in
the RELEASEDIR/RELEASEMACHINEDIR/installation/cdrom direc-
tory by ``make release''. These smaller images usually
contain the same tools as the larger images in
RELEASEDIR/iso, but do not contain additional content such
as the distribution sets.
2007-08-30 14:29:02 +04:00
Note that the mac68k port still uses an older method of
creating CD-ROM images. This requires the mkisofs(1) util-
ity, which is not part of NetBSD, but which can be
installed from pkgsrc/sysutils/cdrtools.
regression-tests
Can only be run after building the regression tests in the
directory ``regress''. Runs those compiled regression
tests on the local host. Note that most tests are now man-
aged instead using atf(7); this target should probably run
those as well but currently does not.
The "build.sh" script
This script file is a Bourne shell script designed to build the entire
NetBSD system on any host with a Bourne shell in /bin/sh, including many
that are not POSIX compliant. Note that if a host system's /bin/sh is
unusually old and broken, the Korn Shell (/bin/ksh), if available, may be
a usable alternative.
All cross-compile builds, and most native builds, of the entire system
should make use of build.sh rather than just running ``make''. This way,
the make(1) program will be bootstrapped properly, in case the host sys-
tem has an older or incompatible ``make'' program.
When compiling the entire system via build.sh, many 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 build.sh are
noted where applicable.
Rework how build.sh functions, so that command line options set various parameters, and a list of "operations" defines what to do. The full usage is show below.

2003-01-23 19:24:08 +03:00
The following operations are supported by build.sh:
build Build the system as per ``make build''. Before the main
part of the build commences, this command runs the obj
operation (unless the -o option is given), ``make
cleandir'' (unless the -u option is given), and the tools
operation.

sets Perform ``make sets''.
sourcesets Perform ``make sourcesets''.
syspkgs Perform ``make syspkgs''.
iso-image Perform ``make iso-image''.
iso-image-source
Perform ``make iso-image-source''.
The following command line options alter the behaviour of the build.sh
operations described above:
-a arch Set the value of MACHINE_ARCH to arch.
-B buildid
Set the value of BUILDID to buildid. This will also append the
build identifier to the name of the ``make'' wrapper script so
2003-07-18 06:19:55 +04:00
that the resulting name is of the form
``nbmake-MACHINE-BUILDID''.
-C cdextras
Set the value of CDEXTRA to cdextras which is a space-separated
list of files or directories which will be added in order to
the CD-ROM image when used in conjunction with ``iso-image'' or
``iso-image-source''. 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.
-D dest Set the value of DESTDIR to dest. If a relative path is speci-
fied, it will be converted to an absolute path before being
used.
-E Set `expert' mode. This overrides various sanity checks, and
allows: DESTDIR does not have to be set to a non-root path for
builds, and MKUNPRIVED=yes does not have to be set when build-
ing as a non-root user.
Note: It is highly recommended that you know what you are doing
when you use this option.
-h Print a help message.
-j njob Run up to njob make(1) subjobs in parallel; passed through to
make(1). If you see failures for reasons other than running
out of memory while using build.sh with -j, please save com-
plete build logs so the failures can be analyzed.
To achieve the fastest builds, -j values between (1 + the num-
ber of CPUs) and (2 * the number of CPUs) are recommended. Use
lower values on machines with limited memory or I/O bandwidth.
-M obj Set MAKEOBJDIRPREFIX to obj. For instance, if the source
directory is /usr/src, a setting of ``-M /usr/obj'' will place
build-time files under /usr/obj/usr/src/bin,
/usr/obj/usr/src/lib, /usr/obj/usr/src/usr.bin, and so forth.
If a relative path is specified, it will be converted to an
absolute path before being used. Unsets MAKEOBJDIR. See ``-O
-obj'' for more information.
-m mach Set the value of MACHINE to mach, except in some special cases
listed below. This will also override any value of
MACHINE_ARCH in the process environment with a value deduced
from mach, unless -a is specified. All cross builds require
-m, but if unset on a NetBSD host, the host's value of MACHINE
will be detected and used automatically.
Some machines support multiple values for MACHINE_ARCH. The
following special cases for the mach argument are defined to
set the listed values of MACHINE and MACHINE_ARCH:
mach MACHINE MACHINE_ARCH
evbarm evbarm (not set)
evbarm-eb evbarm armeb
evbarm-el evbarm arm
evbmips evbmips (not set)
evbmips-eb evbmips mipseb
evbmips-el evbmips mipsel
evbsh3 evbsh3 (not set)
evbsh3-eb evbsh3 sh3eb
evbsh3-el evbsh3 sh3el
sbmips sbmips (not set)
sbmips-eb sbmips mipseb
sbmips-el sbmips mipsel
-N noiselevel
Set the ``noisyness'' level of the build, by setting
MAKEVERBOSE to noiselevel.
-n Show the commands that would be executed by build.sh, but do
not make any changes. This is similar in concept to ``make
-n''.
-O obj Create an appropriate transform macro for MAKEOBJDIR that will
place the built object files under obj. For instance, a set-
ting of ``-O /usr/obj'' will place build-time files under
/usr/obj/bin, /usr/obj/lib, /usr/obj/usr.bin, and so forth. If
a relative path is specified, it will be converted to an abso-
lute path before being used. Unsets MAKEOBJDIRPREFIX.
In normal use, exactly one of the -M or -O options should be
specified. If neither -M nor -O is specified, then a default
object directory will be chosen according to rules in
<bsd.obj.mk>. Relying on this default is not recommended
because it is determined by complex rules that are influenced
by the values of several variables and by the location of the
source directory.
-o Set the value of MKOBJDIRS to ``no''. Otherwise, it will be
automatically set to ``yes''. This default is opposite to the
behaviour when not using build.sh.
-R rel Set the value of RELEASEDIR to rel. If a relative path is
specified, it will be converted to an absolute path before
being used.
-r Remove the contents of DESTDIR and TOOLDIR before building
(provides a clean starting point). This will skip deleting
DESTDIR if building on a native system to the root directory.
-S seed Change the value of BUILDSEED to seed. This should rarely be
necessary.
-T tools Set the value of TOOLDIR to tools. If a relative path is spec-
ified, it will be converted to an absolute path before being
used. If set, the bootstrap ``make'' will only be rebuilt if
the source files for make(1) have changed.
-U Set MKUNPRIVED=yes.
-u Set MKUPDATE=yes.
-V var=[value]
Set the environment variable var to an optional value. This is
propagated to the nbmake wrapper.
-w wrapper
Create the nbmake wrapper script (see below) in a custom loca-
tion, specified by wrapper. This allows, for instance, to
place the wrapper in PATH automatically. Note that wrapper is
the full name of the file, not just a directory name. If a
relative path is specified, it will be converted to an absolute
path before being used.
-X x11src
Set the value of X11SRCDIR to x11src. If a relative path is
specified, it will be converted to an absolute path before
being used.
-x Set MKX11=yes.
-Z var Unset ("zap") the environment variable var. This is propagated
to the nbmake wrapper.
The "nbmake-MACHINE" wrapper script
If using the build.sh script to build NetBSD, a nbmake-MACHINE script
will be created in TOOLDIR/bin upon the first build to assist in building
subtrees on a cross-compile host.
nbmake-MACHINE can be invoked in lieu of make(1), and will instead call
the up-to-date version of ``nbmake'' installed into TOOLDIR/bin with sev-
eral key variables pre-set, including MACHINE, MACHINE_ARCH, and TOOLDIR.
nbmake-MACHINE will also set variables specified with -V, and unset vari-
ables specified with -Z.
This script can be symlinked into a directory listed in PATH, or called
with an absolute path.

Notes: `-b' has been deprecated (it always occurs now) `-d' is replaced by "distribution" `-R rel' onlys sets RELEASEDIR; use "release" to build a release `-k kern' has been replaced by "kernel=kern" `-i idir' has been replaced by "install=idir" -r now occurs before nbmake is rebuilt Add a copyright (long due!). Rework the code to (a KNF inspired) ShellNF. Use functions appropriately. Allow `nb' prefix to be easily changed to something else. Solve world peace (just kidding) This is part of the (never achievable) goal of attempting to make NetBSD easier to build... --8<-- new usage follows --8<-- Usage: build.sh [-EnorUu] [-a arch] [-B buildid] [-D dest] [-j njob] [-M obj] [-m mach] [-O obj] [-R release] [-T tools] [-V var=[value]] [-w wrapper] [operation [...] ] System build operations (all imply "obj" and "tools"): build Run "make build" distribution Run "make distribution" (includes etc/ files) release Run "make release" (includes kernels & distrib media) Other operations: obj Run "make obj" (default unless -o) tools Build and install tools kernel=conf Build kernel with config file `conf' install=idir Run "make installworld" to `idir' (useful after 'distribution' or 'release') Options: -a arch Set MACHINE_ARCH to arch (otherwise deduced from MACHINE) -B buildId Set BUILDID to buildId -D dest Set DESTDIR to dest -E Set "expert" mode; disables some DESTDIR checks -j njob Run up to njob jobs in parallel; see make(1) -M obj Set obj root directory to obj (sets MAKEOBJDIRPREFIX) -m mach Set MACHINE to mach (not required if NetBSD native) -n Show commands that would be executed, but do not execute them -O obj Set obj root directory to obj (sets a MAKEOBJDIR pattern) -o Set MKOBJDIRS=no (do not create objdirs at start of build) -R release Set RELEASEDIR to release -r Remove contents of TOOLDIR and DESTDIR before building -T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in the environment, nbmake will be (re)built unconditionally. -U Set UNPRIVED -u Set UPDATE -V v=[val] Set variable `v' to `val' -w wrapper Create nbmake script as wrapper (default: ${TOOLDIR}/bin/nbmake-${MACHINE})

Using unprivileged mode, build a complete distribution to a DESTDIR
directory that build.sh selects (and will display).
3. # ./build.sh [options] -U install=/
As root, install to / the distribution that was built by example 2.
Even though this is run as root, -U is required so that the permis-
sions stored in DESTDIR/METALOG are correctly applied to the files
as they're copied to /.
4. % ./build.sh [options] -U -u release
Using unprivileged mode, build a complete release to DESTDIR and
RELEASEDIR directories that build.sh selects (and will display).
MKUPDATE=yes (-u) is set to prevent the ``make cleandir'', so that
if this is run after example 2, it doesn't need to redo that portion
of the release build.

OBSOLETE VARIABLES
NBUILDJOBS Use the make(1) option -j instead.
USE_NEW_TOOLCHAIN
The new toolchain is now the default. To disable, use
TOOLCHAIN_MISSING=yes.

HISTORY
The build.sh based build scheme was introduced for NetBSD 1.6 as
USE_NEW_TOOLCHAIN, and re-worked to TOOLCHAIN_MISSING after that.
