# $NetBSD: Makefile,v 1.125 2001/06/10 13:15:29 mrg 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.
|
|
# beforeinstall: creates the distribution directories.
|
|
# do-force-domestic: check's that FORCE_DOMESTIC isn't set (deprecated.)
|
|
# do-share-mk: installs /usr/share/mk files.
|
|
# do-cleandir: clean's the tree.
|
|
# do-make-obj: create's object directories if required.
|
|
# do-check-egcs: check's that we have a modern enough compiler (deprecated.)
|
|
# 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.
