#
# Makefile.config
#
# Common configuration and setup file to generate the ACPICA tools and
# utilities: the iASL compiler, acpiexec, acpihelp, acpinames, acpisrc,
# acpixtract, acpibin.
#
# This file is included by the individual makefiles for each tool.
#

#
# Note: This makefile is intended to be used from within the native
# ACPICA directory structure, from under generate/unix. It specifically
# places all object files in a generate/unix subdirectory, not within
# the various ACPICA source directories. This prevents collisions
# between different compilations of the same source file with different
# compile options, and prevents pollution of the source code.
#

#
# Configuration
# Notes:
#   $(BITS) must be set to either 32 or 64
#   gcc should be version 4 or greater, otherwise some of the options
#       used will not be recognized.
#   Global optimization flags (such as -O2, -Os) are not used, since
#       they cause issues on some compilers.
#   The _GNU_SOURCE symbol is required for many hosts.
