Makefile revision 1.178

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# UPDATE, if defined, will avoid a `make cleandir' at the start of 27# `make build', as well as having the effects listed in 28# /usr/share/mk/bsd.README. 29# NOCLEANDIR, if defined, will avoid a `make cleandir' at the start 30# of the `make build'. 31# NOINCLUDES will avoid the `make includes' usually done by `make build'. 32# 33# Targets: 34# build: 35# Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is 36# set, this is an empty target. 37# release: 38# Does a `make build,' and then tars up the DESTDIR files 39# into RELEASEDIR, in release(7) format. (See etc/Makefile for 40# more information on this.) 41# regression-tests: 42# Runs the regression tests in "regress" on this host. 43# 44# Targets invoked by `make build,' in order: 45# cleandir: cleans the tree. 46# obj: creates object directories. 47# do-tools: builds host toolchain. 48# do-distrib-dirs: creates the distribution directories. 49# includes: installs include files. 50# do-lib-csu: builds and installs prerequisites from lib/csu. 51# do-lib: builds and installs prerequisites from lib. 52# do-gnu-lib: builds and installs prerequisites from gnu/lib. 53# do-build: builds and installs the entire system. 54 55.if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 56.MAKEFLAGS: -m ${.CURDIR}/share/mk 57.endif 58 59# If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 60# not be the top level objdir, because "make obj" can happen in the *middle* 61# of "make build" (long after <bsd.own.mk> is calculated it).
