Well I tried your supposed solution, but I have had no success. To which > "hello.py" script are you referring in your description?

I Installed the Ubuntu package that you contribute to python-occ. 2. I got the "segmentation fault". 3. I deactivated the graphic acceleration. 4. I ran the HelloWorld.py example and works. Because of necessary deactivation of graphic acceleration, I compilate python-occ from svn (including mesh and geom modules). Previously I installed Salome and works with out graphic problem (open-cascade of course was installed from Ubuntu10.04 packages) So, because of Salome installation I redefine the CASROOT to opencascade libs in to Salome installation folder. I would like to contribute with python-occ and Ubuntu users developing an Ubuntu package in the native platform. And said good bye to segmentation fault. I will appreciate if you would like to help me to do so. ¿Did you develop the python-occ package in native Ubuntu 10.04 environment or from virtual machine running over different native environment? Best regards, Marcos.
