Makefile revision 1.155
1# $NetBSD: Makefile,v 1.155 2001/11/13 17:47:16 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# cleandir: cleans the tree. 48# obj: creates object directories. 49# do-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.if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 58.MAKEFLAGS: -m ${.CURDIR}/share/mk 59.endif 60 61.include <bsd.own.mk> 62 63# Sanity check: make sure that "make build" is not invoked simultaneously 64# with a standard recursive target. 65 66.if make(build) || make(release) || make(snapshot) 67.for targ in ${TARGETS:Nobj:Ncleandir} 68.if make(${targ}) && !target(.BEGIN) 69.BEGIN: 70 @echo 'BUILD ABORTED: "make build" and "make ${targ}" are mutually exclusive.' 71 @false 72.endif 73.endfor 74.endif 75 76.if defined(NBUILDJOBS) 77_J= -j${NBUILDJOBS} 78.endif 79 80_SUBDIR= tools lib include gnu bin games libexec sbin usr.bin \ 81 usr.sbin share sys etc distrib regress 82 83# Weed out directories that don't exist. 84 85.for dir in ${_SUBDIR} 86.if exists(${dir}/Makefile) && (${BUILD_${dir}:Uyes} != "no") 87SUBDIR+= ${dir} 88.endif 89.endfor 90 91.if exists(regress) 92regression-tests: 93 @echo Running regression tests... 94 @(cd ${.CURDIR}/regress && ${MAKE} regress) 95.endif 96 97.if ${MKMAN} != "no" 98afterinstall: whatis.db 99whatis.db: 100 (cd ${.CURDIR}/share/man && ${MAKE} makedb) 101.endif 102 103# Targets (in order!) called by "make build". 104 105.if !defined(UPDATE) && !defined(NOCLEANDIR) 106BUILDTARGETS+= cleandir 107.endif 108.if ${MKOBJDIRS} != "no" 109BUILDTARGETS+= obj 110.endif 111.if ${USETOOLS} == "yes" 112BUILDTARGETS+= do-tools 113.endif 114.if !defined(NODISTRIBDIRS) 115BUILDTARGETS+= do-distrib-dirs 116.endif 117.if !defined(NOINCLUDES) 118BUILDTARGETS+= includes 119.endif 120BUILDTARGETS+= do-lib-csu do-lib do-gnu-lib do-build 121 122# Enforce proper ordering of some rules. 123 124.ORDER: ${BUILDTARGETS} 125includes-lib: includes-include includes-sys 126includes-gnu: includes-lib 127 128# Build the system and install into DESTDIR. 129 130build: 131.if defined(BUILD_DONE) 132 @echo "Build already installed into ${DESTDIR}" 133.else 134 @echo -n "Build started at: " && date 135.for tgt in ${BUILDTARGETS} 136 (cd ${.CURDIR} && ${MAKE} ${_J} ${tgt}) 137.endfor 138 @echo -n "Build finished at: " && date 139.endif 140 141# Build a release or snapshot (implies "make build"). 142 143release snapshot: build 144 (cd ${.CURDIR}/etc && ${MAKE} INSTALL_DONE=1 release) 145 146# Special components of the "make build" process. 147 148do-distrib-dirs: 149.if !defined(DESTDIR) || ${DESTDIR} == "" 150 (cd ${.CURDIR}/etc && ${MAKE} DESTDIR=/ distrib-dirs) 151.else 152 (cd ${.CURDIR}/etc && ${MAKE} DESTDIR=${DESTDIR} distrib-dirs) 153.endif 154 155.for dir in tools lib/csu lib gnu/lib 156do-${dir:S/\//-/}: 157.for targ in dependall install 158 (cd ${.CURDIR}/${dir} && ${MAKE} ${_J} ${targ}) 159.endfor 160.endfor 161 162do-build: 163.for targ in dependall install 164 (cd ${.CURDIR} && ${MAKE} ${_J} ${targ} BUILD_tools=no BUILD_lib=no) 165.endfor 166 167# Speedup stubs for some subtrees that don't need to run these rules. 168# (Tells <bsd.subdir.mk> not to recurse for them.) 169 170.for dir in bin etc distrib games libexec regress sbin usr.sbin tools 171includes-${dir}: 172 @true 173.endfor 174.for dir in etc distrib regress 175install-${dir}: 176 @true 177.endfor 178 179# XXX this needs to change when distrib Makefiles are recursion compliant 180dependall-distrib depend-distrib all-distrib: 181 @true 182 183.include <bsd.obj.mk> 184.include <bsd.subdir.mk> 185 186build-docs: ${.CURDIR}/BUILDING 187${.CURDIR}/BUILDING: BUILDING.mdoc 188 groff -mdoc -Tascii -P-b -P-u -P-o $> >$@ 189
