[yt-users] Fw: mpi4py on Kraken (XT5)

[Matthew Turk]

Hi Stephen,

In my statically compiled libpython2.5.a, I have these symbols defined:

0000000000000b20 T PyGILState_Ensure
0000000000000ce0 T PyGILState_Release

Can you tell me which version of python you are compiling with, and
also send the *actual* C compiler line that failed?  In my umath.a I
have those two symbols undefined:

                 U PyGILState_Ensure
                 U PyGILState_Release

Did you modify the distutils code as per the GPAW instructions?  I
have noticed their indentation is a bit unclear; the function they
provide as "link_shared_object" should in fact be a *member* of
UnixCCompiler, so it should be indented an additional level beyond
what is obvious in the code sample.  In fact, this seems likely to be
the culprit here, now that I think about it...
