Makefile revision 1.137
1# $NetBSD: Makefile,v 1.137 2001/10/19 02:35:45 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-build: builds and installs the entire system. 53 54.include "${.CURDIR}/share/mk/bsd.own.mk" 55 56# Sanity check: make sure that "make build" is not invoked simultaneously 57# with a standard recursive target. 58 59.if make(build) || make(release) || make(snapshot) 60.for targ in ${TARGETS:Nobj:Ncleandir} 61.if make(${targ}) && !target(.BEGIN) 62.BEGIN: 63 @echo 'BUILD ABORTED: "make build" and "make ${targ}" are mutually exclusive.' 64 @false 65.endif 66.endfor 67.endif 68 69.if defined(NBUILDJOBS) 70_J= -j${NBUILDJOBS} 71.endif 72 73.if ${USETOOLS} != "no" 74_SUBDIR+= tools 75.endif 76_SUBDIR+= lib include gnu bin games libexec sbin usr.bin \ 77 usr.sbin share sys etc distrib regress 78 79# Weed out directories that don't exist. 80 81.for dir in ${_SUBDIR} 82.if exists(${dir}/Makefile) 83SUBDIR+= ${dir} 84.endif 85.endfor 86 87.if exists(regress) 88regression-tests: 89 @echo Running regression tests... 90 @cd ${.CURDIR}/regress && ${MAKE} ${_M} regress 91.endif 92 93.if ${MKMAN} != "no" 94afterinstall: whatis.db 95whatis.db: 96 cd ${.CURDIR}/share/man && ${MAKE} ${_M} makedb 97.endif 98 99# Targets (in order!) called by "make build". 100 101.if ${MKOBJDIRS:Uno} != "no" 102BUILDTARGETS+= obj 103.endif 104.if !defined(UPDATE) && !defined(NOCLEANDIR) 105BUILDTARGETS+= cleandir 106.endif 107.if ${USETOOLS} != "no" 108BUILDTARGETS+= do-make-tools 109.endif 110.if !defined(NODISTRIBDIRS) 111BUILDTARGETS+= do-distrib-dirs 112.endif 113.if !defined(NOINCLUDES) 114BUILDTARGETS+= includes 115.endif 116BUILDTARGETS+= do-build 117 118# Enforce proper ordering of some rules. 119 120.ORDER: ${BUILDTARGETS} 121includes-lib: includes-include includes-sys 122includes-gnu: includes-lib 123 124# Build the system and install into DESTDIR. 125 126build: 127.if defined(BUILD_DONE) 128 @echo "Build already installed into ${DESTDIR}" 129.else 130 @echo -n "Build started at: " && date 131 @${MAKE} ${_J} ${_M} ${BUILDTARGETS} 132 @echo -n "Build finished at: " && date 133.endif 134 135# Build a release or snapshot (implies "make build"). 136 137release snapshot: build 138 cd ${.CURDIR}/etc && ${MAKE} ${_M} INSTALL_DONE=1 release 139 140# Special components of the "make build" process. 141 142do-make-tools: 143 cd ${.CURDIR}/tools && ${MAKE} ${_M} build 144 145do-distrib-dirs: 146 cd ${.CURDIR}/etc && ${MAKE} ${_M} DESTDIR=${DESTDIR} distrib-dirs 147 148do-build: 149.for dir in lib/csu lib gnu/lib 150.for targ in dependall install 151 cd ${.CURDIR}/${dir} && \ 152 ${MAKE} ${_M} ${_J} MKSHARE=no MKLINT=no ${targ} 153.endfor 154.endfor 155 ${MAKE} ${_M} ${_J} dependall 156 ${MAKE} ${_M} ${_J} install 157 158# Speedup stubs for some subtrees that don't need to run these rules. 159# (Tells <bsd.subdir.mk> not to recurse for them.) 160 161includes-bin includes-games includes-libexec includes-regress \ 162includes-sbin includes-usr.sbin includes-tools \ 163all-tools install-tools install-regress: 164 @true 165 166.include "${.CURDIR}/share/mk/bsd.subdir.mk" 167 168_M:= -m ${.CURDIR}/share/mk 169
