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

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