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.
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.
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.
16 # Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
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.
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.
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

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.
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.
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).
