Makefile revision 1.148
1# $NetBSD: Makefile,v 1.148 2001/11/01 15:48:39 jmc 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.if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 58.MAKEFLAGS: -m ${.CURDIR}/share/mk 59.endif 60 61MKOBJDIRS ?= no 62 63.include <bsd.own.mk> 64 65# Sanity check: make sure that "make build" is not invoked simultaneously 66# with a standard recursive target. 67 68.if make(build) || make(release) || make(snapshot) 69.for targ in ${TARGETS:Nobj:Ncleandir} 70.if make(${targ}) && !target(.BEGIN) 71.BEGIN: 72 @echo 'BUILD ABORTED: "make build" and "make ${targ}" are mutually exclusive.' 73 @false 74.endif 75.endfor 76.endif 77 78.if defined(NBUILDJOBS) 79_J= -j${NBUILDJOBS} 80.endif 81 82_SUBDIR= tools lib include gnu bin games libexec sbin usr.bin \ 83 usr.sbin share sys etc distrib regress 84 85# Weed out directories that don't exist. 86 87.for dir in ${_SUBDIR} 88.if exists(${dir}/Makefile) 89SUBDIR+= ${dir} 90.endif 91.endfor 92 93.if exists(regress) 94regression-tests: 95 @echo Running regression tests... 96 @cd ${.CURDIR}/regress && ${MAKE} regress 97.endif 98 99.if ${MKMAN} != "no" 100afterinstall: whatis.db 101whatis.db: 102 cd ${.CURDIR}/share/man && ${MAKE} makedb 103.endif 104 105# Targets (in order!) called by "make build". 106 107.if ${MKOBJDIRS:Uno} != "no" 108BUILDTARGETS+= obj 109.endif 110.if !defined(UPDATE) && !defined(NOCLEANDIR) 111BUILDTARGETS+= cleandir 112.endif 113.if ${USETOOLS} == "yes" 114BUILDTARGETS+= do-make-tools 115.endif 116.if !defined(NODISTRIBDIRS) 117BUILDTARGETS+= do-distrib-dirs 118.endif 119.if !defined(NOINCLUDES) 120BUILDTARGETS+= includes 121.endif 122BUILDTARGETS+= do-lib-csu do-lib do-gnu-lib do-build 123 124# Enforce proper ordering of some rules. 125 126.ORDER: ${BUILDTARGETS} 127includes-lib: includes-include includes-sys 128includes-gnu: includes-lib 129 130# Build the system and install into DESTDIR. 131 132build: 133.if defined(BUILD_DONE) 134 @echo "Build already installed into ${DESTDIR}" 135.else 136 @echo -n "Build started at: " && date 137.for tgt in ${BUILDTARGETS} 138 ${MAKE} ${_J} ${tgt} 139.endfor 140 @echo -n "Build finished at: " && date 141.endif 142 143# Build a release or snapshot (implies "make build"). 144 145release snapshot: build 146 cd ${.CURDIR}/etc && ${MAKE} INSTALL_DONE=1 release 147 148# Special components of the "make build" process. 149 150do-make-tools: 151 cd ${.CURDIR}/tools && ${MAKE} build 152 153do-distrib-dirs: 154.if !defined(DESTDIR) || ${DESTDIR} == "" 155 cd ${.CURDIR}/etc && ${MAKE} DESTDIR=/ distrib-dirs 156.else 157 cd ${.CURDIR}/etc && ${MAKE} DESTDIR=${DESTDIR} distrib-dirs 158.endif 159 160.for dir in lib/csu lib gnu/lib 161do-${dir:S/\//-/}: 162.for targ in dependall install 163 cd ${.CURDIR}/${dir} && \ 164 ${MAKE} ${_J} MKSHARE=no MKLINT=no ${targ} 165.endfor 166.endfor 167 168do-build: 169 ${MAKE} ${_J} dependall 170 ${MAKE} ${_J} install 171 172# Speedup stubs for some subtrees that don't need to run these rules. 173# (Tells <bsd.subdir.mk> not to recurse for them.) 174 175includes-bin includes-games includes-libexec includes-regress \ 176includes-sbin includes-usr.sbin includes-tools \ 177dependall-tools depend-tools all-tools install-tools install-regress \ 178dependall-distrib depend-distrib all-distrib install-distrib includes-distrib: 179 @true 180 181.include <bsd.subdir.mk> 182 183# Rules for building the BUILDING.* documentation files. 184 185build-docs: ${.CURDIR}/BUILDING.txt ${.CURDIR}/BUILDING.html 186 187.SUFFIXES: .mdoc .html .txt 188 189.mdoc.html: ${.CURDIR}/Makefile 190 groff -mdoc2html -Tlatin1 -P-b -P-u -P-o -ww -mtty-char $< >$@ 191 192# The awk expression changes line endings from LF to CR-LF to make 193# this readable on many more platforms than just Un*x. 194.mdoc.txt: ${.CURDIR}/Makefile 195 groff -mdoc -Tascii -P-b -P-u -P-o $< | \ 196 awk 'BEGIN{ORS="\r\n"}{print}' >$@ 197
