1# $FreeBSD$
2#
3# Option file for FreeBSD /usr/src builds.
4#
5# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
6# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
7# with sensible (usually) defaults.
8#
9# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
10# are applicable for that Makefile (typically there are none, but sometimes there
11# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
12# to omit from that make.
13#
14# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
15# variable.
16#
17# Makefiles may also assume that this file is included by src.opts.mk should it
18# need variables defined there prior to the end of the Makefile where
19# bsd.{subdir,lib.bin}.mk is traditionally included.
20#
21# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
22# should be added. Old instances should be removed since they were just to
23# bridge the gap between FreeBSD 4 and FreeBSD 5.
24#
25# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
26# exception is made for _WITHOUT_SRCONF which turns off this mechanism
27# completely inside bsd.*.mk files).
28#

36# Define MK_* variables (which are either "yes" or "no") for users
37# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
38# make(1) environment.
39# These should be tested with `== "no"' or `!= "no"' in makefiles.
40# The NO_* variables should only be set by makefiles for variables
41# that haven't been converted over.
42#
43
44# These options are used by the src builds. Those listed in
45# __DEFAULT_YES_OPTIONS default to 'yes' and will build unless turned
46# off.  __DEFAULT_NO_OPTIONS will default to 'no' and won't build
47# unless turned on. Any options listed in 'BROKEN_OPTIONS' will be
48# hard-wired to 'no'.  "Broken" here means not working or
49# not-appropriate and/or not supported. It doesn't imply something is
50# wrong with the code. There's not a single good word for this, so
51# BROKEN was selected as the least imperfect one considered at the
52# time. Options are added to BROKEN_OPTIONS list on a per-arch basis.
53# At this time, there's no provision for mutually incompatible options.
