[Developers] Fwd: Cactus_dev compilation with Intel Mac + gcc

[David Rideout]

Hi Bernard,

I hope you don't mind my forwarding this to the developers list, but
it should be of general interest...  I get the same exact errors when
trying to compile Cactus on a powerpc Mac.  Some recent commit must
have broken Cactus on a Mac?

(Also maybe it was Erik which started this thread you speak of?  I
don't think it was me.)

Cheers,
David

Hi David.

I found the tail-end of a Cactus + Mac discussion that you initiated on
the cactus "Users" mailing list a few weeks ago. Does this mean you're
happily compiling Cactus on your Mac?

I checked out cactusdev recently, and totally failed to compile on my
Mac (both with gcc-4.0 or gcc-3.3). The errors set in early (after
config), with messages like the following appearing when working on
CactusBase/Boundary/ScalarBoundary

[ and so on ...]

this seems to be something fundamental, and doesn't arise when compiling
the stable version of Cactus.

I could go to the Users mailing list with this, but thought you might
have some quick explanation of what's happening. Any input -- including
whom else I should bother -- is appreciated.

Thanks,

Bernard
