Package: gfortran
Severity: wishlist


I use to need module dependency information. Since gfortran can not, actually, fetch it like C's gcc does with -M, I use the following Makefile rule:

Makefile.dep : *.F95
	for j in *.F95 ; do for i in `cat $$j|grep " use "|awk '{print $$2}'`; do echo `basename $$j .F95`.o : $$i.mod ; done ; done > $@

It would be great to have this very simple code included in gfortran like the -M option, to be allowed to change the Makefile to something simpler:

Makefile.dep
	for i in *.F95; do gfortran -MM "$${i}"; done > $@

Thanks

I believe that the issue has been fixed upstream in GCC 4.6.0.

>From http://gcc.gnu.org/gcc-4.6/changes.html:
"Support the generation of Makefile dependencies via the -M...
 flags of GCC; you may need to specify the -cpp option in addition.
 The dependencies take modules, Fortran's include, and CPP's #include
 into account. Note: Using -M for the module path is no longer
 supported, use -J instead."
