Makefile revision 1.129
1# $NetBSD: Makefile,v 1.129 2001/09/21 21:01:13 tv Exp $ 2 3# This is the top-level makefile for building NetBSD. For an outline of 4# how to build a snapshot or release, as well as other release engineering 5# information, see http://www.netbsd.org/developers/releng/index.html 6# 7# Not everything you can set or do is documented in this makefile. In 8# particular, you should review the files in /usr/share/mk (especially 9# bsd.README) for general information on building programs and writing 10# Makefiles within this structure, and see the comments in src/etc/Makefile 11# for further information on installation and release set options. 12# 13# Variables listed below can be set on the make command line (highest 14# priority), in /etc/mk.conf (middle priority), or in the environment 15# (lowest priority). 16# 17# Variables: 18# DESTDIR is the target directory for installation of the compiled 19# software. It defaults to /. Note that programs are built against 20# libraries installed in DESTDIR. 21# MKMAN, if set to `no', will prevent building of manual pages. 22# MKOBJDIRS, if not set to `no', will build object directories at 23# an appropriate point in a build. 24# MKSHARE, if set to `no', will prevent building and installing 25# anything in /usr/share. 26# NBUILDJOBS is the number of jobs to start in parallel during a 27# `make build'. It defaults to 1. 28# UPDATE, if defined, will avoid a `make cleandir' at the start of 29# `make build', as well as having the effects listed in 30# /usr/share/mk/bsd.README. 31# NOCLEANDIR, if defined, will avoid a `make cleandir' at the start 32# of the `make build'. 33# NOINCLUDES will avoid the `make includes' usually done by `make build'. 34 35# 36# Targets: 37# build: builds a full release of netbsd in DESTDIR. If BUILD_DONE is 38# set, this is an empty target. 39# release: does a `make build,' and then tars up the DESTDIR files 40# into RELEASEDIR, in release(7) format. (See etc/Makefile for 41# more information on this.) 42# snapshot: a synonym for release. 43# 44# Sub targets of `make build,' in order: 45# buildstartmsg: displays the start time of the build. 46# beforeinstall: creates the distribution directories. 47# do-force-domestic: check's that FORCE_DOMESTIC isn't set (deprecated.) 48# do-share-mk: installs /usr/share/mk files. 49# do-cleandir: cleans the tree. 50# do-make-obj: creates object directories if required. 51# do-make-tools: builds host toolchain. 52# do-make-includes: install include files. 53# do-lib-csu: build & install startup object files. 54# do-lib: build & install system libraries. 55# do-gnu-lib: build & install gnu system libraries. 56# do-dependall: builds & install the entire system. 57# do-domestic: build & install the domestic tree (deprecated.) 58# do-whatisdb: build & install the `whatis.db' man database. 59# buildendmsg: displays the end time of the build. 60 61.include <bsd.own.mk> 62 63MKOBJDIRS ?= no 64 65.if defined(NBUILDJOBS) 66_J= -j${NBUILDJOBS} 67.endif 68 69.if defined(DESTDIR) 70_M=-m ${DESTDIR}/usr/share/mk 71.endif 72 73# NOTE THAT etc *DOES NOT* BELONG IN THE LIST BELOW 74 75SUBDIR+= lib include bin libexec sbin usr.bin usr.sbin share sys 76.if make(cleandir) || make(obj) 77SUBDIR+= distrib 78.ifdef MAKEOBJDIRPREFIX 79SUBDIR+= etc 80.endif 81.endif 82 83includes-lib: includes-include includes-sys 84 85.if exists(games) 86SUBDIR+= games 87.endif 88 89SUBDIR+= gnu 90# This is needed for libstdc++ and gen-params. 91includes-gnu: includes-include includes-sys 92 93.if exists(regress) 94.ifmake !(install) 95SUBDIR+= regress 96.endif 97 98regression-tests: 99 @echo Running regression tests... 100 @(cd ${.CURDIR}/regress && ${MAKE} ${_M} regress) 101.endif 102 103buildstartmsg: 104 @echo -n "Build started at: " 105 @date 106 107buildendmsg: 108 @echo -n "Build finished at: " 109 @date 110 111# If sharesrc is around, use its share/mk files to bootstrap until the 112# mk files are installed (first step of make build).
