3#
4# This is the top-level makefile for building NetBSD. For an outline of
5# how to build a snapshot or release, as well as other release engineering
6# information, see http://www.NetBSD.org/developers/releng/index.html
7#
8# Not everything you can set or do is documented in this makefile. In
9# particular, you should review the files in /usr/share/mk (especially
10# bsd.README) for general information on building programs and writing
11# Makefiles within this structure, and see the comments in src/etc/Makefile
12# for further information on installation and release set options.
13#
14# Variables listed below can be set on the make command line (highest
15# priority), in /etc/mk.conf (middle priority), or in the environment
16# (lowest priority).
17#
18# Variables:
19#   DESTDIR is the target directory for installation of the compiled
20#	software. It defaults to /. Note that programs are built against
21#	libraries installed in DESTDIR.
22#   MKMAN, if `no', will prevent building of manual pages.
23#   MKOBJDIRS, if not `no', will build object directories at
24#	an appropriate point in a build.
25#   MKSHARE, if `no', will prevent building and installing
26#	anything in /usr/share.
27#   MKUPDATE, if not `no', will avoid a `make cleandir' at the start of
28#	`make build', as well as having the effects listed in
29#	/usr/share/mk/bsd.README.
30#   NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
31#	of the `make build'.
32#   NOINCLUDES will avoid the `make includes' usually done by `make build'.
33#   NOBINARIES will not build binaries, only includes and libraries
34#
35#   See mk.conf(5) for more details.
36#
37#
38# Targets:
39#   build:
40#	Builds a full release of NetBSD in DESTDIR, except for the
41#	/etc configuration files.
42#	If BUILD_DONE is set, this is an empty target.
43#   distribution:
44#	Builds a full release of NetBSD in DESTDIR, including the /etc
45#	configuration files.
46#   buildworld:
47#	As per `make distribution', except that it ensures that DESTDIR
48#	is not the root directory.
49#   installworld:
50#	Install the distribution from DESTDIR to INSTALLWORLDDIR (which
51#	defaults to the root directory).  Ensures that INSTALLWORLDDIR
52#	is not the root directory if cross compiling.
53#   release:
54#	Does a `make distribution', and then tars up the DESTDIR files
55#	into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format.
56#	(See etc/Makefile for more information on this.)
57#   regression-tests:
58#	Runs the regression tests in "regress" on this host.
59#   sets:
60#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets
61#	from ${DESTDIR}
62#   sourcesets:
63#	Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
64#   syspkgs:
65#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs
66#	from ${DESTDIR}
67#   iso-image:
68#	Create CD-ROM image in RELEASEDIR/images.
69#	RELEASEDIR must already have been populated by `make release'
70#	or equivalent.
71#   iso-image-source:
72#	Create CD-ROM image with source in RELEASEDIR/images.
73#	RELEASEDIR must already have been populated by
74#	`make release sourcesets' or equivalent.
75#   live-image:
76#	Create bootable live image for emulators or USB stick etc.
77#	in RELEASEDIR/liveimage.
78#	RELEASEDIR must already have been populated by `make release'
79#	or equivalent.
80#   install-image:
81#	Create bootable installation image for USB stick etc.
82#	in RELEASEDIR/installimage.
83#	RELEASEDIR must already have been populated by `make release'
84#	or equivalent.
85#
86# Targets invoked by `make build,' in order:
87#   cleandir:        cleans the tree.
88#   do-top-obj:      creates the top level object directory.
89#   do-tools-obj:    creates object directories for the host toolchain.
90#   do-tools:        builds host toolchain.
91#   params:          record the values of variables that might affect the
92#                    build.
93#   obj:             creates object directories.
94#   do-distrib-dirs: creates the distribution directories.
95#   includes:        installs include files.
96#   do-lib:          builds and installs prerequisites from lib.
97#   do-compat-lib:   builds and installs prerequisites from compat/lib
98#                    if ${MKCOMPAT} != "no".
99#   do-x11:          builds and installs X11 tools and libraries
100#                    from src/external/mit/xorg if ${MKX11} != "no".
101#   do-build:        builds and installs the entire system.
102#   do-extsrc:       builds and installs extsrc if ${MKEXTSRC} != "no".
103#   do-obsolete:     installs the obsolete sets (for the postinstall-* targets).
