Makefile revision 1.227 1 # $NetBSD: Makefile,v 1.227 2004/01/08 07:01:06 lukem Exp $

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-x11: builds and installs X11R6 from src/x11 if ${MKX11} != "no"
80 # do-obsolete: installs the obsolete sets (for the postinstall-* targets).
