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). # .if !target(____) ____: .include # # Define MK_* variables (which are either "yes" or "no") for users # to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the # make(1) environment. # These should be tested with `== "no"' or `!= "no"' in makefiles. # The NO_* variables should only be set by makefiles for variables # that haven't been converted over. # # These options are used by the src builds.
