[BACK]Return to Makefile CVS log [TXT][DIR] Up to [cvs.NetBSD.org] / src

Revision 1.300, Sun Nov 4 11:02:11 2012 UTC (20 months, 2 weeks ago) by apb
Branch: MAIN
Changes since 1.299: +25 -2 lines

Create a "params" file in the top-level .OBJDIR during "make build".
This file will contain the values of all variables that can affect
the build process.  Take care not to update the file's timestamp if
the contents do not change.

${_SRC_TOP_OBJ}/params is referenced by ${_NETBSD_VERSION_DEPENDS} in
bsd.own.mk.

Rename the old "params" target to "show-params".  This simply
prints the values of the variables that can affect the build.

#	$NetBSD: Makefile,v 1.300 2012/11/04 11:02:11 apb 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 `no', will prevent building of manual pages.
#   MKOBJDIRS, if not `no', will build object directories at
#	an appropriate point in a build.
#   MKSHARE, if `no', will prevent building and installing
#	anything in /usr/share.
#   MKUPDATE, if not `no', 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'.
#
#   See mk.conf(5) for more details.
#
#
# Targets:
#   build:
#	Builds a full release of NetBSD in DESTDIR, except for the
#	/etc configuration files.
#	If BUILD_DONE is set, this is an empty target.
#   distribution:
#	Builds a full release of NetBSD in DESTDIR, including the /etc
#	configuration files.
#   buildworld:
#	As per `make distribution', except that it ensures that DESTDIR
#	is not the root directory.
#   installworld:
#	Install the distribution from DESTDIR to INSTALLWORLDDIR (which
#	defaults to the root directory).  Ensures that INSTALLWORLDDIR
#	is not the root directory if cross compiling.
#   release:
#	Does a `make distribution', and then tars up the DESTDIR files
#	into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format.
#	(See etc/Makefile for more information on this.)
#   regression-tests:
#	Runs the regression tests in "regress" on this host.
#   sets:
#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets
#	from ${DESTDIR}
#   sourcesets:
#	Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
#   syspkgs:
#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs
#	from ${DESTDIR}
#   iso-image:
#	Create CD-ROM image in RELEASEDIR/iso.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#   iso-image-source:
#	Create CD-ROM image with source in RELEASEDIR/iso.
#	RELEASEDIR must already have been populated by
#	`make release sourcesets' or equivalent.
#   live-image:
#	Create bootable live image for emulators or USB stick etc.
#	in RELEASEDIR/liveimage.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#   install-image:
#	Create bootable installation image for USB stick etc.
#	in RELEASEDIR/installimage.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#
# Targets invoked by `make build,' in order:
#   cleandir:        cleans the tree.
#   do-top-obj:      creates the top level object directory.
#   do-tools-obj:    creates object directories for the host toolchain.
#   do-tools:        builds host toolchain.
#   params:          record the values of variables that might affect the
#                    build.
#   obj:             creates object directories.
#   do-distrib-dirs: creates the distribution directories.
#   includes:        installs include files.
#   do-tools-compat: builds the "libnbcompat" library; needed for some
#                    random host tool programs in the source tree.
#   do-lib:          builds and installs prerequisites from lib
#                    if ${MKCOMPAT} != "no".
#   do-compat-lib:   builds and installs prerequisites from compat/lib
#                    if ${MKCOMPAT} != "no".
#   do-build:        builds and installs the entire system.
#   do-x11:          builds and installs X11 if ${MKX11} != "no"; either
#                    X11R7 from src/external/mit/xorg if ${X11FLAVOUR} == "Xorg"
#                    or X11R6 from src/x11
#   do-extsrc:       builds and installs extsrc if ${MKEXTSRC} != "no".
#   do-obsolete:     installs the obsolete sets (for the postinstall-* targets).
