Using the MPI-2 library: OpenMPI #1

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1. Compiling NumPy with OpenMPI 1.3.3.
2. import numpy (distnumpy).

Results in the following error:
{{{
python: symbol lookup error: /usr/local/lib/openmpi/mca_paffinity_linux.so:
undefined symbol: mca_base_param_reg_int
}}}

It can be fixed by importing the shared library manually in Python like:
{{{
import ctypes
ctypes.CDLL('libmpi.so.0', ctypes.RTLD_GLOBAL)
}}}
