Makefile revision 1.329
1# $NetBSD: Makefile,v 1.329 2019/08/25 06:06:48 kamil 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# NOBINARIES will not build binaries, only includes and libraries 34# 35# See mk.conf(5) for more details. 36# 37# 38# Targets: 39# build: 40# Builds a full release of NetBSD in DESTDIR, except for the 41# /etc configuration files. 42# If BUILD_DONE is set, this is an empty target. 43# distribution: 44# Builds a full release of NetBSD in DESTDIR, including the /etc 45# configuration files. 46# buildworld: 47# As per `make distribution', except that it ensures that DESTDIR 48# is not the root directory. 49# installworld: 50# Install the distribution from DESTDIR to INSTALLWORLDDIR (which 51# defaults to the root directory). Ensures that INSTALLWORLDDIR 52# is not the root directory if cross compiling. 53# release: 54# Does a `make distribution', and then tars up the DESTDIR files 55# into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format. 56# (See etc/Makefile for more information on this.) 57# regression-tests: 58# Runs the regression tests in "regress" on this host. 59# sets: 60# Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets 61# from ${DESTDIR} 62# sourcesets: 63# Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR} 64# syspkgs: 65# Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs 66# from ${DESTDIR} 67# iso-image: 68# Create CD-ROM image in RELEASEDIR/images. 69# RELEASEDIR must already have been populated by `make release' 70# or equivalent. 71# iso-image-source: 72# Create CD-ROM image with source in RELEASEDIR/images. 73# RELEASEDIR must already have been populated by 74# `make release sourcesets' or equivalent. 75# live-image: 76# Create bootable live image for emulators or USB stick etc. 77# in RELEASEDIR/liveimage. 78# RELEASEDIR must already have been populated by `make release' 79# or equivalent. 80# install-image: 81# Create bootable installation image for USB stick etc. 82# in RELEASEDIR/installimage. 83# RELEASEDIR must already have been populated by `make release' 84# or equivalent. 85# 86# Targets invoked by `make build,' in order: 87# cleandir: cleans the tree. 88# do-top-obj: creates the top level object directory. 89# do-tools-obj: creates object directories for the host toolchain. 90# do-tools: builds host toolchain. 91# params: record the values of variables that might affect the 92# build. 93# obj: creates object directories. 94# do-distrib-dirs: creates the distribution directories. 95# includes: installs include files. 96# do-lib: builds and installs prerequisites from lib. 97# do-compat-lib: builds and installs prerequisites from compat/lib 98# if ${MKCOMPAT} != "no". 99# do-x11: builds and installs X11 tools and libraries 100# from src/external/mit/xorg if ${MKX11} != "no". 101# do-build: builds and installs the entire system. 102# do-extsrc: builds and installs extsrc if ${MKEXTSRC} != "no". 103# do-obsolete: installs the obsolete sets (for the postinstall-* targets). 104# 105 106.if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 107.MAKEFLAGS: -m ${.CURDIR}/share/mk 108.endif 109 110# 111# If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 112# not be the top level objdir, because "make obj" can happen in the *middle* 113# of "make build" (long after <bsd.own.mk> is calculated it).
