Brian -
Sorry for the slow reply, I've been on vacation for a while and am still
digging out from all the back e-mail.
Anyway, that makes sense. Open MPI's default build mode is to dlopen()
the driver components needed for things like the various interconnects
and process starters we support. S
Brian,
I think I have figured this one out. By default ctypes calls dlopen
with mode = RTLD_LOCAL (except on Mac OS 10.3). When I instruct
ctypes to set mode = RTLD_GLOBAL it works fine on 10.4. Based on the
dlopen man page:
RTLD_GLOBAL Symbols exported from this image (dynamic
Thanks for the information. I've filed a bug in our bug tracker on this
issue. It appears that for some reason, when libmpi is dlopened() by
python, that objects it then dlopens are not able to find symbols in the
libmpi. It will probably take me a bit of time to track this issue
down, but you w

Sure, but my example will probably seem a little odd. I am calling
the mpi shared library from Python using ctypes.
The dependencies for doing things this way are:
1. Python built with --enable-shared
2. The ctypes python package
3. OpenMPI configured with --enable-shared
Once you h
This is quite strange, and we're having some trouble figuring out
exactly why the opening is failing. Do you have a (somewhat?) easy list
of instructions so that I can try to reproduce this?
Thanks,
Brian
