# Rules and Macros for building opens source software that uses configure /
# GNU auto* tools to configure their build for the system they are on.  This
# uses GNU Make to build the components to take advantage of the viewpath
# support and build multiple version (32/64 bit) from a shared source.
#
# To use these rules, include ../make-rules/configure.mk in your Makefile
# and define "build", "install", and "test" targets appropriate to building
# your component.
# Ex:
#
# 	build:		$(SOURCE_DIR)/build/$(MACH32)/.built \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.built
#
#	install:	$(SOURCE_DIR)/build/$(MACH32)/.installed \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.installed
#
#	test:		$(SOURCE_DIR)/build/$(MACH32)/.tested \
#	 		$(SOURCE_DIR)/build/$(MACH64)/.tested
#
# Any additional pre/post configure, build, or install actions can be specified
# in your make file by setting them in on of the following macros:
#	COMPONENT_PRE_CONFIGURE_ACTION, COMPONENT_POST_CONFIGURE_ACTION
#	COMPONENT_PRE_BUILD_ACTION, COMPONENT_POST_BUILD_ACTION
#	COMPONENT_PRE_INSTALL_ACTION, COMPONENT_POST_INSTALL_ACTION
#	COMPONENT_PRE_TEST_ACTION, COMPONENT_POST_TEST_ACTION
#
# If component specific make targets need to be used for build or install, they
# can be specified in
#	COMPONENT_BUILD_TARGETS, COMPONENT_INSTALL_TARGETS
#	COMPONENT_TEST_TARGETS
#

# If the component prefers 64-bit binaries, then ensure builds deliver 64-bit
# binaries to the standard directories and 32-bit binaries to the non-standard
# location.  This allows simplification of package manifests and makes it
# easier to deliver the 64-bit binaries as the default.
