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

|
# These should be tested with `== "no"' or `!= "no"' in makefiles.
