Revision 1.136, Fri Oct 12 21:05:08 2001 UTC (12 years, 6 months ago) by nathanw
Branch: MAIN
Changes since 1.135: +2 -2 lines

Use @true instead of @${TRUE} in includes-foo targets, since there is no
variable TRUE defined in our makefile system.

This prevents "make includes" from breaking with older bsd.subdir.mk, and is
more consistent with the uses of "true" in the rest of the tree.

#	$NetBSD: Makefile,v 1.136 2001/10/12 21:05:08 nathanw Exp $

# This is the top-level makefile for building NetBSD. For an outline of
# how to build a snapshot or release, as well as other release engineering
# information, see http://www.netbsd.org/developers/releng/index.html
#
# Not everything you can set or do is documented in this makefile. In
# particular, you should review the files in /usr/share/mk (especially
# bsd.README) for general information on building programs and writing
# Makefiles within this structure, and see the comments in src/etc/Makefile
# for further information on installation and release set options.
#
# Variables listed below can be set on the make command line (highest
# priority), in /etc/mk.conf (middle priority), or in the environment
# (lowest priority).
#
# Variables:
#   DESTDIR is the target directory for installation of the compiled
#	software. It defaults to /. Note that programs are built against
#	libraries installed in DESTDIR.
#   MKMAN, if set to `no', will prevent building of manual pages.
#   MKOBJDIRS, if not set to `no', will build object directories at 
#	an appropriate point in a build.
#   MKSHARE, if set to `no', will prevent building and installing
#	anything in /usr/share.
#   NBUILDJOBS is the number of jobs to start in parallel during a
#	`make build'. It defaults to 1.
#   UPDATE, if defined, will avoid a `make cleandir' at the start of
#     `make build', as well as having the effects listed in
#     /usr/share/mk/bsd.README.
#   NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
#     of the `make build'.
#   NOINCLUDES will avoid the `make includes' usually done by `make build'.

#
# Targets:
#   build: builds a full release of netbsd in DESTDIR. If BUILD_DONE is
#	set, this is an empty target.
#   release: does a `make build,' and then tars up the DESTDIR files
#	into RELEASEDIR, in release(7) format. (See etc/Makefile for
#	more information on this.)
#   snapshot: a synonym for release.
#
# Sub targets of `make build,' in order:
#   buildstartmsg: displays the start time of the build.
#   do-make-tools: builds host toolchain.
#   do-distrib-dirs: creates the distribution directories.
#   do-force-domestic: check's that FORCE_DOMESTIC isn't set (deprecated.)
#   do-cleandir: cleans the tree.
#   do-make-obj: creates object directories if required.
#   do-make-includes: install include files.
#   do-lib-csu: build & install startup object files.
#   do-lib: build & install system libraries.
#   do-gnu-lib: build & install gnu system libraries.
#   do-dependall: builds & install the entire system.
#   do-domestic: build & install the domestic tree (deprecated.)
#   do-whatisdb: build & install the `whatis.db' man database.
#   buildendmsg: displays the end time of the build.
