Return to Makefile.params CVS log

Up to [cvs.NetBSD.org] / src / etc

remove the xfree86 reachover makefiles and the vast majority of
the support in the rest of the source tree.

X11 sets could use some cleaning up perhaps (just deletion, as
we've never really marked the old X11R6 as obsolete for native
xorg using platforms so far either.)

#	$NetBSD: Makefile.params,v 1.13 2015/07/23 08:03:25 mrg Exp $
#
# Makefile fragment for printing build parameters.
#
# Public variables:
#	RELEASEVARS
#		List of variables whose value should be printed.
#
#	PRINT_PARAMS
#		A command to print the desired variables and values
#		to stdout, without any additional debugging information.
#		Values are printed as single-quoted strings, with
#		embedded quotes and newlines escaped in a way that's
#		acceptable to sh(1).  Undefined values are printed
#		as "(undefined)" (without quotation marks).
#
# Internal targets:
# 	_params:
#		Prints the names and values of all the variables
#		listed in ${RELEASEVARS}.  The desired results may be
#		redirected somewhere other than stdout, for example by
#		setting _params_redirect='>&3'.	 stdout and stderr may
#		contain unwanted debugging information, from make and
#		the shell.
#
# Internal variables:
#	_params_redirect:
#		If set, this should be a shell redirection specification, such
#		as '>&3', controlling where the output from "make _params" will
#		be sent.
#
# Example:
#	. ${NETBSDSRCDIR}/etc/Makefile.params
#	show-params: .MAKE .PHONY # print params to stdout
#		@${PRINT_PARAMS}
#

.include <bsd.own.mk>	# for some variables

# PRINT_PARAMS:
#
# The output from the "make _params" can include the following types of
# unwanted lines:
#
#     make -j prints "--- _params ---";
#
#     if MAKEVERBOSE is set to 3 or more then make prints each "printf"
#     command in addition to executing it;
#
#     if MAKEVERBOSE is set to 4 then the shell prints each command
#     (prefixed with "+").
#
# So the resulting output can look like this:
#
#	--- _params ---
#	+ echo 'printf "%20s = '\''%-s'\''\n" BSDOBJDIR /usr/obj'
#	printf "%20s = '%-s'\n" BSDOBJDIR /usr/obj
#	+ printf '%20s = '\''%-s'\''\n' BSDOBJDIR /usr/obj
#	           BSDOBJDIR = '/usr/obj'
#	+ echo 'printf "%20s = '\''%-s'\''\n" BSDSRCDIR /usr/src'
#	printf "%20s = '%-s'\n" BSDSRCDIR /usr/src
#	+ printf '%20s = '\''%-s'\''\n' BSDSRCDIR /usr/src
#	           BSDSRCDIR = '/usr/src'
#	[...]
#
# where what we want is just this:
#
#	           BSDOBJDIR = '/usr/obj'
#	           BSDSRCDIR = '/usr/src'
#	           [...]
#
# The shell redirections in ${PRINT_PARAMS} ensure that the unwanted
# noise is discarded (via ">/dev/null"), while the desired information
# ends up on the subshell's stdout (via ">&3" and "3>&1").  The value
# of _params_redirect is passed in the environment instead of on the
# command line, to prevent it from appearing in MAKEFLAGS (which would
# appear in the output).
