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#
34#   See mk.conf(5) for more details.
35#
36#
37# Targets:
38#   build:
39#	Builds a full release of NetBSD in DESTDIR, except for the
40#	/etc configuration files.
41#	If BUILD_DONE is set, this is an empty target.
42#   distribution:
43#	Builds a full release of NetBSD in DESTDIR, including the /etc
44#	configuration files.
45#   buildworld:
46#	As per `make distribution', except that it ensures that DESTDIR
47#	is not the root directory.
48#   installworld:
49#	Install the distribution from DESTDIR to INSTALLWORLDDIR (which
50#	defaults to the root directory).  Ensures that INSTALLWORLDDIR
51#	is the not root directory if cross compiling.
52#   release:
53#	Does a `make build', and then tars up the DESTDIR files
54#	into RELEASEDIR/${MACHINE}, in release(7) format.
55#	(See etc/Makefile for more information on this.)
56#   regression-tests:
57#	Runs the regression tests in "regress" on this host.
58#   sets:
59#	Populate ${RELEASEDIR}/${MACHINE}/binary/sets from ${DESTDIR}
60#   sourcesets:
61#	Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
62#
63# Targets invoked by `make build,' in order:
64#   cleandir:        cleans the tree.
65#   obj:             creates object directories.
66#   do-tools:        builds host toolchain.
67#   do-distrib-dirs: creates the distribution directories.
68#   includes:        installs include files.
69#   do-tools-compat: builds the "libnbcompat" library; needed for some
70#                    random host tool programs in the source tree.
71#   do-gnu-lib-libgcc3: builds and installs prerequisites from gnu/lib/libgcc3
72#   do-lib-csu:      builds and installs prerequisites from lib/csu.
73#   do-lib-libc:     builds and installs prerequisites from lib/libc.
74#   do-lib:          builds and installs prerequisites from lib.
75#   do-gnu-lib:      builds and installs prerequisites from gnu/lib.
76#   do-ld.so:        builds and installs prerequisites from libexec/ld.*_so.
77#   do-build:        builds and installs the entire system.
78#   do-x11:          builds and installs X11R6 from src/x11 if ${MKX11} != "no"
79#   do-obsolete:     installs the obsolete sets (for the postinstall-* targets).
