Makefile revision 1.333 
1#	$NetBSD: Makefile,v 1.333 2006/07/23 11:44:55 lukem Exp $

4# Environment variables without default values:
5#   DESTDIR must be set before anything in this file will work.
6#   RELEASEDIR is where the tarred up stuff for a snapshot or
7#	release will be placed.
8#
9# Environment variables with default values:
10#   LOCALTIME will set the default local time for the system you
11#	build; it determines what /etc/localtime is symlink'd to.
12#   KERNSRCDIR points to kernel source; it is set by default to ../sys,
13#	but can be overridden.
14#   KERNOBJDIR is the kernel build directory, it defaults to
15#	${KERNSRCDIR}/arch/${MACHINE}/compile, but can be overridden.
16#   KERNCONFDIR is where the configuration files for kernels are found;
17#	default is ${KERNSRCDIR}/arch/${MACHINE}/conf but can be overridden.
18#   MKCRYPTO; if not `no', install crypto-related configuration
19#   MKPOSTFIX; if not `no', install postfix configuration
20#   MKUNPRIVED; if not `no', allow non-root installs.
21#   MKUPDATE; if not `no', don't do a 'make clean' before kernel compile
22#
23# Targets:
24#    distribution: makes a full NetBSD distribution in DESTDIR. If
25#	INSTALL_DONE is set, it will not do a `make install.'
26#	if DISTRIBUTION_DONE is set, it will not do anything.
27#    distrib-dirs: creates an empty NetBSD directory tree in DESTDIR.
28#	Called by distribution.
29#    snapshot: calls distribution, above, and then tars up the files
30#	into a release(7) format in RELEASEDIR/${RELEASEMACHINEDIR}.
31#	Any port-dependent stuff for this target is found in
32#	etc.${MACHINE}/Makefile.inc.
33#    release: a synonym for `snapshot'

470# build kernels --
471#	This target builds the kernels specified by each port.
472#	A port may specify the following kernels:
473#
474#	KERNEL_SETS		The list of kernels that will be
475#				packaged into sets, named
476#				kern-${kernel}.tgz.  These kernels
477#				are also placed in the binary/kernel
478#				area of the release package as
479#				netbsd-${kernel}.gz.
480#
481#	EXTRA_KERNELS		Additional kernels to place in the
482#				binary/kernel area of the release
483#				package as netbsd-${kernel}.gz, but
484#				which are not placed into sets. This
485#				allows a port to provide e.g. a netbootable
486#				installation kernel containing a ramdisk.
487#
488#	BUILD_KERNELS		Additional kernels to build which are
489#				not placed into sets nor into the
490#				binary/kernel area of the release
491#				package.  These are typically kernels
492#				that are built for inclusion only in
493#				installation disk/CD-ROM/tape images.
494#
495#	A port may also specify KERNEL_SUFFIXES, which is an optional list
496#	of filename suffixes for kernels to include in the kernel sets and
497#	in the binary/kernel area of the release package (e.g. "netbsd" vs.
498#	"netbsd.ecoff" and "netbsd.srec").  It is not an error if kernels
499#	with these suffixes do not exist in the kernel build directory.
500#
