1# $FreeBSD$ 2# 3# Option file for src builds. 4# 5# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf 6# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no} 7# with (usually) sensible defaults. 8# 9# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that 10# are applicable for that Makefile (typically there are none, but sometimes there 11# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish 12# to omit from that make. 13# 14# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO 15# variable. 16# 17# Makefiles may also assume that this file is included by bsd.own.mk should it 18# need variables defined there prior to the end of the Makefile where 19# bsd.{subdir,lib.bin}.mk is traditionally included. 20# 21# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them 22# should be added. Old instances should be removed since they were just to 23# bridge the gap between FreeBSD 4 and FreeBSD 5. 24# 25# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an 26# exception is made for _WITHOUT_SRCONF which turns off this mechanism 27# completely). 28# 29 30.if !target(__<bsd.opts.mk>__) 31__<bsd.opts.mk>__: 32 33.if !defined(_WITHOUT_SRCCONF) 34# 35# Define MK_* variables (which are either "yes" or "no") for users 36# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the 37# make(1) environment. 38# These should be tested with `== "no"' or `!= "no"' in makefiles. 39# The NO_* variables should only be set by makefiles for variables 40# that haven't been converted over. 41# 42 43# Only these options are used by bsd.*.mk.
