2# Option file for bmake builds. These options are available to all users of
3# bmake (including the source tree userland and kernel builds). They generally
4# control how binaries are made, shared vs dynamic, etc and some general options
5# relevant for all build environments.
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 (usually) sensible 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 bsd.own.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).

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# Only these options are used by bsd.*.mk. KERBEROS and OPENSSH are
46# unfortunately needed to support statically linking the entire
47# tree. su(1) wouldn't link since it depends on PAM which depends on
48# ssh libraries when building with OPENSSH, and likewise for KERBEROS.
49
50# All other variables used to build /usr/src live in src.opts.mk
51# and variables from both files are documented in src.conf(5).
