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).
