.include <bsd.own.mk> # for configuration variables. |
# 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. |
|
# NBUILDJOBS is the number of jobs to start in parallel during a |
|
# `make build'. It defaults to 1. |
|
# 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: |
|
# obj: creates object directories. |
|
# cleandir: cleans the tree. |
|
# 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. |
