There are some papers about this very subject. Maybe they are useful to you: http://www.nicdan.id.au/computers/compiling/recompile.html As a side note, I recall some compilers that don't touch the .mod file if the new content to write is the same as the existent one. IIRC it was the case for g95, but not for gfortran. -- Alberto _______________________________________________ Help-make mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-make
