1.95 cjs 2:
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:
1.101 sommerfe 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.
1.95 cjs 21: # MKMAN, if set to `no', will prevent building of manual pages.
1.101 sommerfe 22: # MKOBJDIRS, if not set to `no', will build object directories at
23: # an appropriate point in a build.
1.95 cjs 24: # MKSHARE, if set to `no', will prevent building and installing
25: # anything in /usr/share.
1.101 sommerfe 26: # NBUILDJOBS is the number of jobs to start in parallel during a
1.127 tv 27: # `make build'. It defaults to 1.
1.125 mrg 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'.
1.119 toddpw 33: # NOINCLUDES will avoid the `make includes' usually done by `make build'.
1.95 cjs 34: #
35: # Targets:
1.137 tv 36: # build:
37: # Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is
1.110 jlam 38: # set, this is an empty target.
1.137 tv 39: # release:
40: # Does a `make build,' and then tars up the DESTDIR files
1.95 cjs 41: # into RELEASEDIR, in release(7) format. (See etc/Makefile for
42: # more information on this.)
1.137 tv 43: # regression-tests:
44: # Runs the regression tests in "regress" on this host.
1.123 mrg 45: #
1.137 tv 46: # Targets invoked by `make build,' in order:
1.155 tv 47: # cleandir: cleans the tree.
1.137 tv 48: # obj: creates object directories.
1.152 tv 49: # do-tools: builds host toolchain.
1.131 tv 50: # do-distrib-dirs: creates the distribution directories.
1.137 tv 51: # includes: installs include files.

53: # do-lib: builds and installs prerequisites from lib.
54: # do-gnu-lib: builds and installs prerequisites from gnu/lib.
