3# This is the top-level makefile for building NetBSD. 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.
