Hi David, I hope its not a compatability issue. Here are the steps I followed
1. Downloaded python source and compiled with intel compiler.
2. Downloaded boost 1.36 and checkout bgl_python from svn repository of osl.iu.edu.
3. Followed the instructions for building/installing boost, boost.python, and bgl_python.
4. The tests under examples under libs/python/example/ pass.
What about the bgl_python tests?
5. Firedup python and issued command "import boost.graph as bgl". This line fails with error:
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "...../bgl-python/lib/python/boost/graph/__init__.py", line 16, in <module> from boost.graph._graph import * ImportError: "...../bgl-python/lib/python/boost/graph/_graph.so: undefined symbol: _ZN5boost5graph6python11basic_graphINS_11undirectedSEED1Ev"
$ echo '_ZN5boost5graph6python11basic_graphINS_11undirectedSEED1Ev' | c++filt boost::graph::python::basic_graph<boost::undirectedS>::~basic_graph()
From what I can tell, it looks like Intel is failing to instantiate that destructor for some reason. You might try adding an explicit instantiation. In any case, it looks like a compiler bug to me.
5. Tried several permutation/combination of LD_LIBRARY_PATH and sys.path.append('.. ') but with no success.
I also tried with bgl_python in the sandbox and the same issue shows up.
Hmm, I dunno. Another thing worth doing: try it with g++ and see if it works. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
