Revision 1.132, Mon Oct 1 17:19:17 2001 UTC (18 years ago) by mason
Branch: MAIN
Changes since 1.131: +3 -1 lines

UPDATING (1.38) says:

        i386 platform builds must now set TOOLDIR in mk.conf or the
        environment in order to build the system.  This is a pathname
        where host build tools will be installed, and must NOT be
        the same as src/tools.

        (Optionally, USETOOLS=no can be set in the environment if you
        wish to avoid using the separate host toolchain for building a
        subtree.  Otherwise, this will default to "yes" automatically.)

However, building with USETOOLS=no set and no defined TOOLDIR ends up
with breakage, as the do-make-tools target is run regardless of whether
or not USETOOLS is set.

Hence, a wrapper around the body of the do-make-tools target:

.if ${USETOOLS} != "no"

...which makes the build work when USETOOLS=no, with no TOOLDIR set. This
would seem to more accurately match the description put forth in UPDATING.

#	$NetBSD: Makefile,v 1.132 2001/10/01 17:19:17 mason 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.
