3# This is the top-level makefile for building NetBSD. For an outline of
4# how to build a snapshot or release, as well as other release engineering
5# information, see http://www.netbsd.org/developers/releng/index.html
6#
7# Not everything you can set or do is documented in this makefile. In
8# particular, you should review the files in /usr/share/mk (especially
9# bsd.README) for general information on building programs and writing
10# Makefiles within this structure, and see the comments in src/etc/Makefile
11# for further information on installation and release set options.
12#
13# Variables listed below can be set on the make command line (highest
14# priority), in /etc/mk.conf (middle priority), or in the environment
15# (lowest priority).
16#
17# Variables:
18#   DESTDIR is the target directory for installation of the compiled
19#	software. It defaults to /. Note that programs are built against
20#	libraries installed in DESTDIR.
21#   MKMAN, if set to `no', will prevent building of manual pages.
22#   MKOBJDIRS, if not set to `no', will build object directories at 
23#	an appropriate point in a build.
24#   MKSHARE, if set to `no', will prevent building and installing
25#	anything in /usr/share.
26#   NBUILDJOBS is the number of jobs to start in parallel during a
27#	'make build'. It defaults to 1.
28#   UPDATE, if defined, will avoid a `make cleandir' at the start of
29#     `make build', as well as having the effects listed in
30#     /usr/share/mk/bsd.README.
31#   NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
32#     of the `make build'.
33#   NOINCLUDES will avoid the `make includes' usually done by `make build'.
34
35#
36# Targets:
37#   build: builds a full release of netbsd in DESTDIR. If BUILD_DONE is
38#	set, this is an empty target.
39#   release: 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#   snapshot: a synonym for release.
43#
44# Sub targets of `make build,' in order:
45#   buildstartmsg: displays the start time of the build.
46#   beforeinstall: creates the distribution directories.
47#   do-force-domestic: check's that FORCE_DOMESTIC isn't set (deprecated.)
48#   do-share-mk: installs /usr/share/mk files.
49#   do-cleandir: clean's the tree.
50#   do-make-obj: create's object directories if required.
51#   do-check-egcs: check's that we have a modern enough compiler (deprecated.)
52#   do-make-includes: install include files.
53#   do-lib-csu: build & install startup object files.
54#   do-lib: build & install system libraries.
55#   do-gnu-lib: build & install gnu system libraries.
56#   do-dependall: builds & install the entire system.
57#   do-domestic: build & install the domestic tree (deprecated.)
58#   do-whatisdb: build & install the `whatis.db' man database.
59#   buildendmsg: displays the end time of the build.
