problem with OpenMP > 1.3I and boost-mpi-python

Reported by: anonymous Owned by: Douglas Gregor
Milestone: To Be Determined Component: mpi
Version: Boost 1.48.0 Severity: Problem
Keywords: Cc: rrossi@…


when installing with bjam and using openmpi for MPI, the bjam generated can not be loaded from within python.

the packagers for ubuntu solve this problem by putting within a subdirectory boost

so something like my_boost/lib/boost/

together with a file that contains:

import sys if sys.platform == 'linux2':

import DLFCN as dl flags = sys.getdlopenflags() sys.setdlopenflags(dl.RTLD_NOW|dl.RTLD_GLOBAL) import mpi sys.setdlopenflags(flags)


import mpi

this way the mpi library can be imported as

import boost.mpi

this will open the and ensure that the lib can be correctly loaded

without this the lib should be imported as import mpi

which fails with openmpi
