Revision 1.141, Wed Oct 24 01:07:13 2001 UTC (12 years, 5 months ago) by tv
Branch: MAIN
Changes since 1.140: +1 -10 lines

Revert previous.  etc and distrib do now belong in _SUBDIR; the correct fix
for broken builds is to fix the relevant Makefiles as was done for sparc.
This was done in the interest of simplicity of the system build (and the
fact that there may be a need to descend into these directories in the
near future).

#	$NetBSD: Makefile,v 1.141 2001/10/24 01:07:13 tv 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.)
#   regression-tests:
#	Runs the regression tests in "regress" on this host.
#
# Targets invoked by `make build,' in order:
#   obj:             creates object directories.
#   cleandir:        cleans the tree.
#   do-make-tools:   builds host toolchain.
#   do-distrib-dirs: creates the distribution directories.
#   includes:        installs include files.
#   do-build:        builds and installs the entire system.
