1# $FreeBSD$
2#
3# Option file for FreeBSD /usr/src builds, at least the userland and boot loader
4# portions of the tree. These options generally chose what parts of the tree to
5# include or omit and are FreeBSD source tree specific.
6#
7# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
8# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
9# with sensible (usually) defaults.
10#
11# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
12# are applicable for that Makefile (typically there are none, but sometimes there
13# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
14# to omit from that make.
15#
16# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
17# variable.
18#
19# Makefiles may also assume that this file is included by src.opts.mk should it
20# need variables defined there prior to the end of the Makefile where
21# bsd.{subdir,lib.bin}.mk is traditionally included.
22#
23# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
24# should be added. Old instances should be removed since they were just to
25# bridge the gap between FreeBSD 4 and FreeBSD 5.
26#
27# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
28# exception is made for _WITHOUT_SRCONF which turns off this mechanism
29# completely inside bsd.*.mk files).
30#

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