Revision 1.190, Fri Nov 29 23:48:37 2002 UTC (11 years, 4 months ago) by lukem
Branch: MAIN
Changes since 1.189: +6 -1 lines

Add do-{target} aliases for:  cleandir  obj  includes
to be consistent with the other do-TARGET targets for make build.
(These are not used by "make build" per se, they're just to make my
life easier)

#	$NetBSD: Makefile,v 1.190 2002/11/29 23:48:37 lukem 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.
#   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.)
#   regression-tests:
#	Runs the regression tests in "regress" on this host.
# Targets invoked by `make build,' in order:
#   cleandir:        cleans the tree.
#   obj:             creates object directories.
#   do-tools:        builds host toolchain.
#   do-distrib-dirs: creates the distribution directories.
#   includes:        installs include files.
#   do-lib-csu:      builds and installs prerequisites from lib/csu.
#   do-lib-libc:     builds and installs prerequisites from lib/libc.
#   do-lib:          builds and installs prerequisites from lib.
#   do-gnu-lib:      builds and installs prerequisites from gnu/lib.
#   do-ld.so:        builds and installs prerequisites from libexec/ld.*_so.
#   do-build:        builds and installs the entire system.
