acpica/generate/unix/Makefile.config

#
# 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
#
# OPT_CFLAGS can be overridden on the make command line by
#   adding OPT_CFLAGS="..." to the invocation.
#
# Notes:
#   gcc should be version 4 or greater, otherwise some of the options
#     used will not be recognized.
#   Optional: Set HOST to an appropriate value (_LINUX, _FreeBSD, _APPLE, _CYGWIN, etc.)
#     See include/platform/acenv.h for supported values.
#     Note: HOST is not nearly as important for applications as it
#     is for the kernel-resident version of ACPICA, and it may
#     not be necessary to change it.
