Hello Erik,

On this cluster, I get to use gcc 4.1.2.    The optionlist file I've hacked together is below; please ignore the comments, as they are relics of the progenitor file.

By the way, Frank's suggestion works fine as a temporary patch -- not done yet, but I'm a good way through compilation without errors.

There are several dialects of C, and several common extensions. It
turns out that M_PI is not part of the core C standard, but only of
the POSIX standard. This doesn't mean much in practice, since POSIX
(basically Unix) is available on all common systems. Your problem here
is that your compiler, by default, doesn't enable POSIX.

What compiler and what version are you using? We have figured out what
compiler options enable POSIX for most systems, so this may be easy to
do.

Hello,

While setting up a local cluster, I've run into a problem I just don't
understand when compiling.   It seems that the compiler's not finding
<math.h>!  (for one program, at least)  To this point, the compilation
procedure has proceeded without trouble; I've successfully compiled on other
machines.

Thoughts?

Thanks,

-Richard

PS: for reference, the compilation is below

[oshaughn@hydra Cactus]$ ./simfactory/sim build
--thornlist=manifest/einsteintoolkit.th
 --optionlist=simfactory/optionlists/hydra.cfg
