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 set to `no', will prevent building of manual pages.
23#   MKOBJDIRS, if not set to `no', will build object directories at
24#	an appropriate point in a build.
25#   MKSHARE, if set to `no', will prevent building and installing
26#	anything in /usr/share.
27#   UPDATE, if defined, 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# Targets:
35#   build:
36#	Builds a full release of NetBSD in DESTDIR.  If BUILD_DONE is
37#	set, this is an empty target.
38#   release:
39#	Does a `make build,' and then tars up the DESTDIR files
40#	into RELEASEDIR, in release(7) format. (See etc/Makefile for
41#	more information on this.)
42#   regression-tests:
43#	Runs the regression tests in "regress" on this host.
44#
45# Targets invoked by `make build,' in order:
46#   cleandir:        cleans the tree.
47#   obj:             creates object directories.
48#   do-tools:        builds host toolchain.
49#   do-distrib-dirs: creates the distribution directories.
50#   includes:        installs include files.
51#   do-lib-csu:      builds and installs prerequisites from lib/csu.
52#   do-lib-libc:     builds and installs prerequisites from lib/libc.
53#   do-lib:          builds and installs prerequisites from lib.
54#   do-gnu-lib:      builds and installs prerequisites from gnu/lib.
55#   do-ld.so:        builds and installs prerequisites from libexec/ld.*_so.
56#   do-build:        builds and installs the entire system.
