2# Makefile.config
3#
4# Common configuration and setup file to generate the ACPICA tools and
5# utilities: the iASL compiler, acpiexec, acpihelp, acpinames, acpisrc,
6# acpixtract, acpibin.
7#
8# This file is included by the individual makefiles for each tool.
9#
10
11#
12# Note: This makefile is intended to be used from within the native
13# ACPICA directory structure, from under generate/unix. It specifically
14# places all object files in a generate/unix subdirectory, not within
15# the various ACPICA source directories. This prevents collisions
16# between different compilations of the same source file with different
17# compile options, and prevents pollution of the source code.
18#
19
20#
21# Configuration
22#
23# OPT_CFLAGS can be overridden on the make command line by
24#   adding OPT_CFLAGS="..." to the invocation.
25#
26# Notes:
27#   gcc should be version 4 or greater, otherwise some of the options
28#     used will not be recognized.
29#   Optional: Set HOST to an appropriate value (_LINUX, _FreeBSD, _APPLE, _CYGWIN, etc.)
30#     See include/platform/acenv.h for supported values.
31#     Note: HOST is not nearly as important for applications as it
32#     is for the kernel-resident version of ACPICA, and it may
33#     not be necessary to change it.
