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 # UPDATE, if defined, will avoid a `make cleandir' at the start of
27 # `make build', as well as having the effects listed in
28 # /usr/share/mk/bsd.README.
29 # NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
30 # of the `make build'.
31 # NOINCLUDES will avoid the `make includes' usually done by `make build'.
32 #
33 # Targets:
34 # build:
35 # Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is
36 # set, this is an empty target.
37 # release:
38 # Does a `make build,' and then tars up the DESTDIR files
39 # into RELEASEDIR, in release(7) format. (See etc/Makefile for
40 # more information on this.)
41 # regression-tests:
42 # Runs the regression tests in "regress" on this host.
43 #
44 # Targets invoked by `make build,' in order:
45 # cleandir: cleans the tree.
46 # obj: creates object directories.
47 # do-tools: builds host toolchain.
48 # do-distrib-dirs: creates the distribution directories.
49 # includes: installs include files.
50 # do-lib-csu: builds and installs prerequisites from lib/csu.
51 # do-lib-libc: builds and installs prerequisites from lib/libc.
52 # do-lib: builds and installs prerequisites from lib.
53 # do-gnu-lib: builds and installs prerequisites from gnu/lib.
54 # do-ld.so: builds and installs prerequisites from libexec/ld.*_so.
55 # do-build: builds and installs the entire system.
