# SYNOPSIS
|
|
#
|
|
# CHECK_GNU_MAKE()
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro searches for a GNU version of make. If a match is found,
|
|
# the makefile variable `ifGNUmake' is set to the empty string,
|
|
# otherwise it is set to "#". This is useful for including a special
|
|
# features in a Makefile, which cannot be handled by other versions
|
|
# of make. The variable _cv_gnu_make_command is set to the command to
|
|
# invoke GNU make if it exists, the empty string otherwise.
|
|
#
|
|
# Here is an example of its use:
|
|
#
|
|
# Makefile.in might contain:
|
|
#
|
|
# # A failsafe way of putting a dependency rule into a makefile
|
|
# $(DEPEND):
|
|
# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
|
|
#
|
|
# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
|
|
# @ifGNUmake@ include $(DEPEND)
|
|
# @ifGNUmake@ endif
|
|
#
|
|
# Then configure.in would normally contain:
|
|
#
|
|
# CHECK_GNU_MAKE()
|
|
# AC_OUTPUT(Makefile)
|
|
#
|
|
# Then perhaps to cause gnu make to override any other make, we could
|
|
# do something like this (note that GNU make always looks for
|
|
# GNUmakefile first):
|
|
#
|
|
# if ! test x$_cv_gnu_make_command = x ; then
|
|
# mv Makefile GNUmakefile
|
|
# echo .DEFAULT: > Makefile ;
|
|
# echo \ $_cv_gnu_make_command \$@ >> Makefile;
|
|
# fi
|
|
#
|
|
# Then, if any (well almost any) other make is called, and GNU make
|
|
# also exists, then the other make wraps the GNU make.
