Okay, this is really crap. Make that POS use a better predicate than "modified", like "checksum changed".<div>This is what builder does ;)</div><div><br></div><div> Matt<br><br><div class="gmail_quote">

A common trick with regular Makefiles, which you should be to able to adopt, is to:<br><br>generated.c: blah blah FORCE<br> ./generate_it > $@.tmp<br> if cmp generated.c generated.c.tmp; then<br> mv $@.tmp $@<br>
else<br> rm -f $@.tmp<br><br>It's not really pretty, but I think a bit less hacky than mucking with mtime, and it's definitely safe. (I may have the cmp logic reversed, but you get the idea. Instead of .tmp, you could do a separate dir)<br>

</div>It looks like generation of include/finclude/ftn-auto/*.h90 is much<br>
less direct. The dependencies below also produce unused *.h90 files.<br>
What is bfort using to produce these f90module.f90 files? Do you<br>
think it's feasible to get a list of files that each *.h90 depends on?<br>
If not, I guess I'll just live with the few seconds to recompile<br>
these and relink even though nothing changed.<br>
