[Yt-dev] OpenMP HOP

[Matthew Turk]

Hi Stephen,

-DOPENMP should not be in the extra_args.  It should be:

define_macros=[("OPENMP",True)],

Furthermore, are you sure you need to wrap OpenMP stuff in #defines?
Pragmas should pass through the preprocessor without any adjustment.

As for the linkage issues, I'd say play with the output of ldd.  Do
you need to explicitly add "gomp" to the libraries, or is GCC supposed
to handle that itself?

-Matt
