- Subject: libgomp and python: dlopen fails
I'd like to post again the question Iordan Hristov had a couple of
months ago (http://gcc.gnu.org/ml/gcc-help/2006-09/msg00164.html), but
no answer was given back then.
I am using a C++ shared library as a module to import in python
(wrapping my functions into the python API is done by SWIG). This
library depends on libgomp.so. I tried with the gomp version shipped
with RHEL4 gcc-4.1 and with a version compiled by myself from source
(April 2007) on a 64bit Red Hat Linux machine. I get the following error:
ImportError: libgomp.so.1: shared object cannot be dlopen()ed
I have more libraries on which the imported library depends, but they
all work. libgomp also works when I use it in a normal c++ program.
Does anybody have an idea what to do? I must admit that I'm not familiar
with dlopen(). I initially thought that the problem had something to do
with the library being stripped or "nm" not giving me any objects, but
the version compiled by myself didn't have that.
I think that libgomp should be capable of being imported into python,
just as the AMD core math library is.
Greetings
Sebastian
