1499 | dnl This macro searches for a GNU version of make. If a match is found, the | |
1500 | dnl makefile variable `ifGNUmake' is set to the empty string, otherwise it is | |
99b51359 | 1501 | dnl set to "#". This is useful for including a special features in a Makefile, |
29bd52c8 PE |
1502 | dnl which cannot be handled by other versions of make. The variable |
1503 | dnl _cv_gnu_make_command is set to the command to invoke GNU make if it exists, | |
1504 | dnl the empty string otherwise. | |
1505 | dnl | |
1506 | dnl Here is an example of its use: | |
1507 | dnl | |
1508 | dnl Makefile.in might contain: | |
1509 | dnl | |
1510 | dnl # A failsafe way of putting a dependency rule into a makefile | |
1511 | dnl $(DEPEND): | |
1512 | dnl $(CC) -MM $(srcdir)/*.c > $(DEPEND) | |
1513 | dnl | |
1514 | dnl @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND))) | |
1515 | dnl @ifGNUmake@ include $(DEPEND) | |
1516 | dnl @ifGNUmake@ endif | |
1517 | dnl | |
1518 | dnl Then configure.in would normally contain: | |
1519 | dnl | |
1520 | dnl CHECK_GNU_MAKE() | |
1521 | dnl AC_OUTPUT(Makefile) | |
1522 | dnl | |
1523 | dnl Then perhaps to cause gnu make to override any other make, we could do | |
1524 | dnl something like this (note that GNU make always looks for GNUmakefile first): | |
1525 | dnl | |
1526 | dnl if ! test x$_cv_gnu_make_command = x ; then | |
1527 | dnl mv Makefile GNUmakefile | |
1528 | dnl echo .DEFAULT: > Makefile ; | |
1529 | dnl echo \ $_cv_gnu_make_command \$@ >> Makefile; | |
1530 | dnl fi | |
1531 | dnl | |
1532 | dnl Then, if any (well almost any) other make is called, and GNU make also | |
1533 | dnl exists, then the other make wraps the GNU make. | |
1534 | dnl | |
