# $NetBSD: Makefile,v 1.183 2002/08/22 02:23:23 lukem Exp $ # This is the top-level makefile for building NetBSD. For an outline of # how to build a snapshot or release, as well as other release engineering # information, see http://www.netbsd.org/developers/releng/index.html # # Not everything you can set or do is documented in this makefile. In # particular, you should review the files in /usr/share/mk (especially # bsd.README) for general information on building programs and writing # Makefiles within this structure, and see the comments in src/etc/Makefile # for further information on installation and release set options. # # Variables listed below can be set on the make command line (highest # priority), in /etc/mk.conf (middle priority), or in the environment # (lowest priority). # # Variables: # DESTDIR is the target directory for installation of the compiled # software. It defaults to /. Note that programs are built against # libraries installed in DESTDIR. # MKMAN, if set to `no', will prevent building of manual pages. # MKOBJDIRS, if not set to `no', will build object directories at # an appropriate point in a build. # MKSHARE, if set to `no', will prevent building and installing # anything in /usr/share. # UPDATE, if defined, will avoid a `make cleandir' at the start of # `make build', as well as having the effects listed in # /usr/share/mk/bsd.README. # NOCLEANDIR, if defined, will avoid a `make cleandir' at the start # of the `make build'. # NOINCLUDES will avoid the `make includes' usually done by `make build'. # # Targets: # build: # Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is # set, this is an empty target. # release: # Does a `make build,' and then tars up the DESTDIR files # into RELEASEDIR, in release(7) format. (See etc/Makefile for # more information on this.) # regression-tests: # Runs the regression tests in "regress" on this host. # # Targets invoked by `make build,' in order: # cleandir: cleans the tree. # obj: creates object directories. # do-tools: builds host toolchain. # do-distrib-dirs: creates the distribution directories. # includes: installs include files. # do-lib-csu: builds and installs prerequisites from lib/csu. # do-lib: builds and installs prerequisites from lib. # do-gnu-lib: builds and installs prerequisites from gnu/lib. # do-build: builds and installs the entire system. .if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" .MAKEFLAGS: -m ${.CURDIR}/share/mk .endif # If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may # not be the top level objdir, because "make obj" can happen in the *middle* # of "make build" (long after is calculated it).
