Has anyone around here been able to successfully use libMesh with XCode
3.2.3 on OSX?
We've held off from upgrading to 3.2.3 for a while because of an
incompatibility with the Intel compilers.... but that incompatibility was
resolved so we have now tried 3.2.3... with epic failure.
At this point I'm just using 3.2.3 with libMesh by itself. I'm not using
the Intel compiler... nor Petsc. I'm just letting it use all the default
stuff on OSX (including the built in MPI, etc). I'm not passing any options
to libmesh's configure.
So if you want to reproduce this... just "upgrade" to XCode 3.2.3, checkout
libmesh do "./configure" and make in debug mode... then go build ex13 (just
chosen by random) in debug mode and you should see something like:

After looking at the various problems for the past few days it appears to be
having trouble dynamic casting things... but I cannot see why. BUT...
that's not the only problem. Notice the weirdness where the "Mesh
Information" block didn't get printed completely. Some of the examples will
run just fine.. but exhibit weird behavior like incomplete printing of
information, etc.
All in all... it's total weirdness... and I just want to make sure we're not
the only ones seeing it.
I saw this morning that there is an XCode 3.2.4 out as of a week ago... so
I'm going to check that out today... but looking over the release notes I
don't see anything that would lead me to believe that this is fixed. I'll
report back.
If 3.2.4 doesn't work I'm probably just going to have to downgrade to 3.2.2.
That's the situation we've been in for a while... but it is trouble because
we have to tell all of our customers with Macs NOT to upgrade to 3.2.3
(which the OSX software update thing will happily tell them to do all the
time). So it would be nice if we could boil this down to something that
XCode is doing wrong so I can send it off to my Apple contacts so this can
get fixed once and for all.
