# Simple makefile for building a framework or library on platforms other than OS X.
# the open source subset used in Darwin.
#
# These make variables (or environment variables) are used
# if 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 "/tmp/CoreFoundation.obj".
#	SYMROOT		path location where build products will be
#			put; defaults to "/tmp/CoreFoundation.sym".
#	DSTROOT		path location where installed products will
#			be put; defaults to "/tmp/CoreFoundation.dst".
#
# Interesting variables to be set by the including Makefile:
# 	NAME		base name of the framework or library
#	CFILES		.c to build
#	CPP_FILES	.cpp to build
#	PUBLIC_HFILES	.h files that will be installed for clients of API
#	PRIVATE_HFILES	.h files that will be installed for clients of SPI
#	PROJECT_HFILES	the rest of the .h files in the project
#	PUBLIC_IFILES	.i with API
#	PRIVATE_IFILES	.i files with SPI
#	IFILES_DIR	directory holding all the .i files
#	MASTER_INTERFACE_DIR	location of .i files we depend on
#
# We now follow the model of modern PB builds, which allow SYMROOT and OBJROOT to be shared
# across projects during development.  This provides the benefit that one set of build flags
# (-F on Mach, -I and -L on Unix or Cygwin) can be used to share build products across projects.
# For release builds, the directories are always separate per project.
#
#	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_LFLAGS	other flags to be passed to the link stage
#
# (Note: lame "#*/" tacked onto some lines is to get PB to stop syntax coloring the entire rest of the file as a comment.)

# rest of this file.  Currently defined values: Darwin, Linux, FreeBSD, variants of CYGWIN
