# Simple makefile for building objc4 on Darwin
#
# These make variables (or environment variables) are used
# when defined:
#	SRCROOT		path location of root of source hierarchy;
#			defaults to ".", but must be set to a
#			destination path for installsrc target.
#	OBJROOT		path location where .o files will be put;
#			defaults to SRCROOT.
#	SYMROOT		path location where build products will be
#			put; defaults to SRCROOT.
#	DSTROOT		path location where installed products will
#			be put; defaults to / .
# OBJROOT and SYMROOT should not be directories shared with other
# built projects.
#	PLATFORM	name of platform being built on
#	USER		name of user building the project
#	ARCHS		list of archs for which to build
#	RC_ARCHS	more archs for which to build (build system)
#	OTHER_CFLAGS	other flags to be passed to compiler
#	RC_CFLAGS	more flags to be passed to compiler (build system)
#	OTHER_LDFLAGS	other flags to be passed to the link stage
#
