-# 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.
