So do I.
I still can't believe that we threw out a perfectly
decent build system and saddled ourselves with this thing.
In hindsight: do you guys TRULY think it was worth it?
For install/dist/distcheck targets, and out-of-source builds? Yeah.
All I'm trying to do right now is add ONE damn header file - and I
can't seem to find the magic script / sauce to get everything
updated. I ran include/rebuild_include_HEADERS.sh ... nope. I ran
bootstrap... still nope. Oh! Now I remember... I need to run
include/libmesh/rebuild_makefile.sh... NOPE!
Should we put one magic add_files.sh at the top level?
But the two include shell scripts should have done it... that's always
worked for me. I guess I usually manually bootstrap afterwards too,
but in my experience automake is smart enough to rerun itself if it
sees Makefile.am newer than Makefile.in.
Ok - 100% serious here. If I redo the libMesh build system so that
it's autoconf and make based again - would you guys consider
switching to it?
Consider? Yes. Anticipate agreeing to with such a high probability
that the work would be worth your time? No.
Except... if you're going full Focus on creating a new build system,
presumably you'd want to put it in MOOSE too...
And I'd really love to be able to do out-of-source builds in MOOSE
too. If "autoderek" handled that (plus "make install"; I don't care
as much about dist/distcheck) it would be totally worth the switch
from my point of view. You'd still have to convince others though.
(It's not really graft if I let my decisions get swayed for code
rather than money, right? ...)
