Makefile revision 1.125 1 # $NetBSD: Makefile,v 1.125 2001/06/10 13:15:29 mrg Exp $

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.
