Makefile revision 1.143
1# $NetBSD: Makefile,v 1.143 2001/10/24 03:21:20 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# Targets: 36# build: 37# Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is 38# set, this is an empty target. 39# release: 40# Does a `make build,' and then tars up the DESTDIR files 41# into RELEASEDIR, in release(7) format. (See etc/Makefile for 42# more information on this.) 43# regression-tests: 44# Runs the regression tests in "regress" on this host. 45# 46# Targets invoked by `make build,' in order: 47# obj: creates object directories. 48# cleandir: cleans the tree. 49# do-make-tools: builds host toolchain. 50# do-distrib-dirs: creates the distribution directories. 51# includes: installs include files. 52# do-lib-csu: builds and installs prerequisites from lib/csu. 53# do-lib: builds and installs prerequisites from lib. 54# do-gnu-lib: builds and installs prerequisites from gnu/lib. 55# do-build: builds and installs the entire system. 56 57.include "${.CURDIR}/share/mk/bsd.own.mk" 58 59# Sanity check: make sure that "make build" is not invoked simultaneously 60# with a standard recursive target. 61 62.if make(build) || make(release) || make(snapshot) 63.for targ in ${TARGETS:Nobj:Ncleandir} 64.if make(${targ}) && !target(.BEGIN) 65.BEGIN: 66 @echo 'BUILD ABORTED: "make build" and "make ${targ}" are mutually exclusive.' 67 @false 68.endif 69.endfor 70.endif 71 72.if defined(NBUILDJOBS) 73_J= -j${NBUILDJOBS} 74.endif 75 76.if ${USETOOLS} == "yes" 77_SUBDIR+= tools 78.endif 79_SUBDIR+= lib include gnu bin games libexec sbin usr.bin \ 80 usr.sbin share sys etc distrib regress 81 82# Weed out directories that don't exist. 83 84.for dir in ${_SUBDIR} 85.if exists(${dir}/Makefile) 86SUBDIR+= ${dir} 87.endif 88.endfor 89 90.if exists(regress) 91regression-tests: 92 @echo Running regression tests... 93 @cd ${.CURDIR}/regress && ${MAKE} ${_M} regress 94.endif 95 96.if ${MKMAN} != "no" 97afterinstall: whatis.db 98whatis.db: 99 cd ${.CURDIR}/share/man && ${MAKE} ${_M} makedb 100.endif 101 102# Targets (in order!) called by "make build". 103 104.if ${MKOBJDIRS:Uno} != "no" 105BUILDTARGETS+= obj 106.endif 107.if !defined(UPDATE) && !defined(NOCLEANDIR) 108BUILDTARGETS+= cleandir 109.endif 110.if ${USETOOLS} == "yes" 111BUILDTARGETS+= do-make-tools 112.endif 113.if !defined(NODISTRIBDIRS) 114BUILDTARGETS+= do-distrib-dirs 115.endif 116.if !defined(NOINCLUDES) 117BUILDTARGETS+= includes 118.endif 119BUILDTARGETS+= do-lib-csu do-lib do-gnu-lib do-build 120 121# Enforce proper ordering of some rules. 122 123.ORDER: ${BUILDTARGETS} 124includes-lib: includes-include includes-sys 125includes-gnu: includes-lib 126 127# Build the system and install into DESTDIR. 128 129build: 130.if defined(BUILD_DONE) 131 @echo "Build already installed into ${DESTDIR}" 132.else 133 @echo -n "Build started at: " && date 134 @${MAKE} ${_J} ${_M} ${BUILDTARGETS} 135 @echo -n "Build finished at: " && date 136.endif 137 138# Build a release or snapshot (implies "make build"). 139 140release snapshot: build 141 cd ${.CURDIR}/etc && ${MAKE} ${_M} INSTALL_DONE=1 release 142 143# Special components of the "make build" process. 144 145do-make-tools: 146 cd ${.CURDIR}/tools && ${MAKE} ${_M} build 147 148do-distrib-dirs: 149 cd ${.CURDIR}/etc && ${MAKE} ${_M} DESTDIR=${DESTDIR} distrib-dirs 150 151.for dir in lib/csu lib gnu/lib 152do-${dir:S/\//-/}: 153.for targ in dependall install 154 cd ${.CURDIR}/${dir} && \ 155 ${MAKE} ${_M} ${_J} MKSHARE=no MKLINT=no ${targ} 156.endfor 157.endfor 158 159do-build: 160 ${MAKE} ${_M} ${_J} dependall 161 ${MAKE} ${_M} ${_J} install 162 163# Speedup stubs for some subtrees that don't need to run these rules. 164# (Tells <bsd.subdir.mk> not to recurse for them.) 165 166includes-bin includes-games includes-libexec includes-regress \ 167includes-sbin includes-usr.sbin includes-tools \ 168dependall-tools depend-tools all-tools install-tools install-regress \ 169dependall-distrib depend-distrib all-distrib install-distrib includes-distrib: 170 @true 171 172.include "${.CURDIR}/share/mk/bsd.subdir.mk" 173 174_M:= -m ${.CURDIR}/share/mk 175
