BUILDFLAGS.MK(1)	FreeBSD	General	Commands Manual	      BUILDFLAGS.MK(1)

NAME
     buildflags.mk -- import buildflags.conf(1)

SYNOPSIS
     buildflags.mk

DESCRIPTION
     The primary function of the buildflags.mk script is to use	the
     buildflags.conf(1)	file, but it also offers knobs to easily use tools
     such as distcc and	ccache.

     The intended way to use it	is to add the following	lines to make.conf(5).

	   .sinclude "/usr/local/share/bsdadminscripts2/buildflags.mk"

OPTIONS
     The following options to control the internals of buildflags.mk are
     available:

     BUILDFLAGS_CCACHE
	     The ccache	binary.

	     Default: /usr/local/bin/ccache

     BUILDFLAGS_CONF
	     The configuration file.

	     Default: /usr/local/etc/buildflags.conf

     BUILDFLAGS_DISTCC
	     The distcc	binary.

	     Default: /usr/local/bin/distcc

     BUILDFLAGS_PARSER
	     The program that parses the configuration file.

	     Default: /usr/local/share/bsdadminscripts2/buildflags.awk

     BUILDFLAGS_TMP
	     A temporary file required to include the parsed configuration.

	     Default: /tmp/buildflags.tmp.mk.${USER}

     The following additional knobs are	offered	to manipulate make jobs:

     SUBTHREADS
	     WARNING: This setting is deprecated in favour of the ports	native
	     settings FORCE_MAKE_JOBS and MAKE_JOBS_NUMBER.

	     This knob does for	ports what THREADS does	everywhere else. It
	     does not have an effect if	the target install is specified. Thus
	     it	is recommended to run make build and make install seperately.

     THREADS
	     This knob causes make to create parallel jobs. A sensible value
	     is	twice the number of CPU	cores available. This increases	the
	     amount of memory used. If the system starts to swap often,	the
	     number should be decreased	to the number of available CPU cores.
	     Do	not use	THREADS	with the ports system.

     USE_DISTCC
	     Prepends the distcc binary	to CC, CXX and CPP.

     USE_CCACHE
	     Prepends the ccache binary	to CC, CXX and CPP.

     WITH_GCC
	     Triggers the use of the alternative gcc defined with
	     BUILDFLAGS_GCC.  If BUILDFLAGS_GCC	has not	been definied it will
	     be	set to whatever	WITH_GCC was set.

HISTORY
     The buildflags.mk script first appeared in	the bsdadminscripts-2.0	col-
     lection.
