# $NetBSD: build.mk,v 1.14 2007/11/30 18:54:40 rillig Exp $
#
# This file defines what happens in the build phase, excluding the
# self-test, which is defined in test.mk.
#
# Public targets for developers:
#
# build-env:
# Runs an interactive shell (BUILD_ENV_SHELL) in the environment
# that is used for building the package.
#
# Package-settable variables:
#
# BUILD_MAKE_FLAGS is the list of arguments that is passed to the make
# process, in addition to the usual MAKE_FLAGS.
#
# BUILD_TARGET is the target from ${MAKE_FILE} that should be invoked
# to build the sources.
#
# MAKE_JOBS_SAFE
# Whether the package supports parallel builds. If set to yes,
# at most MAKE_JOBS jobs are carried out in parallel. The default
# value is "yes", and packages that don't support it must
# explicitly set it to "no".
#
# Keywords: parallel
#
# Variables defined in this file:
#
# BUILD_MAKE_CMD
# This command sets the proper environment for the build phase
# and runs make(1) on it. It takes a list of make targets and
# flags as argument.
#
# See also:
# mk/build/test.mk
