Makefile revision 1.222
1# $NetBSD: Makefile,v 1.222 2003/12/05 22:33:01 lukem Exp $ 2 3# 4# This is the top-level makefile for building NetBSD. For an outline of 5# how to build a snapshot or release, as well as other release engineering 6# information, see http://www.NetBSD.org/developers/releng/index.html 7# 8# Not everything you can set or do is documented in this makefile. In 9# particular, you should review the files in /usr/share/mk (especially 10# bsd.README) for general information on building programs and writing 11# Makefiles within this structure, and see the comments in src/etc/Makefile 12# for further information on installation and release set options. 13# 14# Variables listed below can be set on the make command line (highest 15# priority), in /etc/mk.conf (middle priority), or in the environment 16# (lowest priority). 17# 18# Variables: 19# DESTDIR is the target directory for installation of the compiled 20# software. It defaults to /. Note that programs are built against 21# libraries installed in DESTDIR. 22# MKMAN, if `no', will prevent building of manual pages. 23# MKOBJDIRS, if not `no', will build object directories at 24# an appropriate point in a build. 25# MKSHARE, if `no', will prevent building and installing 26# anything in /usr/share. 27# MKUPDATE, if not `no', will avoid a `make cleandir' at the start of 28# `make build', as well as having the effects listed in 29# /usr/share/mk/bsd.README. 30# NOCLEANDIR, if defined, will avoid a `make cleandir' at the start 31# of the `make build'. 32# NOINCLUDES will avoid the `make includes' usually done by `make build'. 33# 34# See mk.conf(5) for more details. 35# 36# 37# Targets: 38# build: 39# Builds a full release of NetBSD in DESTDIR, except for the 40# /etc configuration files. 41# If BUILD_DONE is set, this is an empty target. 42# distribution: 43# Builds a full release of NetBSD in DESTDIR, including the /etc 44# configuration files. 45# buildworld: 46# As per `make distribution', except that it ensures that DESTDIR 47# is not the root directory. 48# installworld: 49# Install the distribution from DESTDIR to INSTALLWORLDDIR (which 50# defaults to the root directory). Ensures that INSTALLWORLDDIR 51# is the not root directory if cross compiling. 52# release: 53# Does a `make build', and then tars up the DESTDIR files 54# into RELEASEDIR/${MACHINE}, in release(7) format. 55# (See etc/Makefile for more information on this.) 56# regression-tests: 57# Runs the regression tests in "regress" on this host. 58# sets: 59# Populate ${RELEASEDIR}/${MACHINE}/binary/sets from ${DESTDIR} 60# sourcesets: 61# Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR} 62# 63# Targets invoked by `make build,' in order: 64# cleandir: cleans the tree. 65# obj: creates object directories. 66# do-tools: builds host toolchain. 67# do-distrib-dirs: creates the distribution directories. 68# includes: installs include files. 69# do-tools-compat: builds the "libnbcompat" library; needed for some 70# random host tool programs in the source tree. 71# do-gnu-lib-libgcc3: builds and installs prerequisites from gnu/lib/libgcc3 72# do-lib-csu: builds and installs prerequisites from lib/csu. 73# do-lib-libc: builds and installs prerequisites from lib/libc. 74# do-lib-libdes: builds and installs prerequisites from lib/libdes. 75# do-lib: builds and installs prerequisites from lib. 76# do-gnu-lib: builds and installs prerequisites from gnu/lib. 77# do-ld.so: builds and installs prerequisites from libexec/ld.*_so. 78# do-build: builds and installs the entire system. 79# do-obsolete: installs the obsolete sets (for the postinstall-* targets). 80# 81 82.if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 83.MAKEFLAGS: -m ${.CURDIR}/share/mk 84.endif 85 86# 87# If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 88# not be the top level objdir, because "make obj" can happen in the *middle* 89# of "make build" (long after <bsd.own.mk> is calculated it).
