10 | # SYNOPSIS | ||
11 | # | ||
12 | # CHECK_GNU_MAKE() | ||
13 | # | ||
14 | # DESCRIPTION | ||
15 | # | ||
16 | # This macro searches for a GNU version of make. If a match is found, the | ||
17 | # makefile variable `ifGNUmake' is set to the empty string, otherwise it | ||
18 | # is set to "#". This is useful for including a special features in a | ||
19 | # Makefile, which cannot be handled by other versions of make. The | ||
20 | # variable _cv_gnu_make_command is set to the command to invoke GNU make | ||
21 | # if it exists, the empty string otherwise. | ||
22 | # | ||
23 | # Here is an example of its use: | ||
24 | # | ||
25 | # Makefile.in might contain: | ||
26 | # | ||
27 | # # A failsafe way of putting a dependency rule into a makefile | ||
28 | # $(DEPEND): | ||
29 | # $(CC) -MM $(srcdir)/*.c > $(DEPEND) | ||
30 | # | ||
31 | # @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND))) | ||
32 | # @ifGNUmake@ include $(DEPEND) | ||
33 | # @ifGNUmake@ endif | ||
34 | # | ||
35 | # Then configure.in would normally contain: | ||
36 | # | ||
37 | # CHECK_GNU_MAKE() | ||
38 | # AC_OUTPUT(Makefile) | ||
39 | # | ||
40 | # Then perhaps to cause gnu make to override any other make, we could do | ||
41 | # something like this (note that GNU make always looks for GNUmakefile | ||
42 | # first): | ||
43 | # | ||
44 | # if ! test x$_cv_gnu_make_command = x ; then | ||
45 | # mv Makefile GNUmakefile | ||
46 | # echo .DEFAULT: > Makefile ; | ||
47 | # echo \ $_cv_gnu_make_command \$@ >> Makefile; | ||
48 | # fi | ||
49 | # | ||
50 | # Then, if any (well almost any) other make is called, and GNU make also | ||
51 | # exists, then the other make wraps the GNU make. | ||
