# $NetBSD: Makefile,v 1.182 2002/07/10 23:44:54 uwe 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 set to `no', will prevent building of manual pages.
# MKOBJDIRS, if not set to `no', will build object directories at
# an appropriate point in a build.
# MKSHARE, if set to `no', will prevent building and installing
# anything in /usr/share.
# UPDATE, if defined, 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'.
#
# Targets:
# build:
# Builds a full release of NetBSD in DESTDIR. If BUILD_DONE is
# set, this is an empty target.
# release:
# Does a `make build,' and then tars up the DESTDIR files
# into RELEASEDIR, in release(7) format. (See etc/Makefile for
# more information on this.)
# regression-tests:
# Runs the regression tests in "regress" on this host.
#
# Targets invoked by `make build,' in order:
# cleandir: cleans the tree.
# obj: creates object directories.
# do-tools: builds host toolchain.
# do-distrib-dirs: creates the distribution directories.
# includes: installs include files.
# do-lib-csu: builds and installs prerequisites from lib/csu.
# do-lib: builds and installs prerequisites from lib.
# do-gnu-lib: builds and installs prerequisites from gnu/lib.
# do-build: builds and installs the entire system.

# _SRC_TOP_OBJ_ here so it will not be added to ${.MAKEOVERRIDES}.
