1829 dnl This macro searches for a GNU version of make. If a match is found, the
1830 dnl makefile variable `ifGNUmake' is set to the empty string, otherwise it is
1831 dnl set to "#". This is useful for including a special features in a Makefile,
1832 dnl which cannot be handled by other versions of make. The variable
1833 dnl _cv_gnu_make_command is set to the command to invoke GNU make if it exists,
1834 dnl the empty string otherwise.
1836 dnl Here is an example of its use:
1838 dnl Makefile.in might contain:
1840 dnl # A failsafe way of putting a dependency rule into a makefile
1842 dnl $(CC) -MM $(srcdir)/*.c > $(DEPEND)
1844 dnl @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
1845 dnl @ifGNUmake@ include $(DEPEND)
1846 dnl @ifGNUmake@ endif
1848 dnl Then configure.in would normally contain:
1850 dnl CHECK_GNU_MAKE()
1851 dnl AC_OUTPUT(Makefile)
1853 dnl Then perhaps to cause gnu make to override any other make, we could do
1854 dnl something like this (note that GNU make always looks for GNUmakefile first):
1856 dnl if ! test x$_cv_gnu_make_command = x ; then
1857 dnl mv Makefile GNUmakefile
1858 dnl echo .DEFAULT: > Makefile ;
1859 dnl echo \ $_cv_gnu_make_command \$@ >> Makefile;
1862 dnl Then, if any (well almost any) other make is called, and GNU make also
1863 dnl exists, then the other make wraps the GNU make.
