Hi Denis, Commit 191a184 is sync with OCE-0.6.0dev (in the OCE project, Issue #89 was related to a problem with building pythonocc). There is actually a CMakeLists.txt file, but it is quite old and I usually don't include it in the release package. It was a first attempt to make pythonocc use CMake but I didn't work onthis file for a while. Consider it as outdated. Rather use the python distutils module: $ cd src $ python setup.py build $ python setup.py install And everything should compile properly. Note that you have to download/compile the latest svn rev of salomegeometry (which is also available in the pythonocc /src/contrib/geom-5.1.5.9 folder). If you don't want to use the geom wrapper, use: $ python setup.py build --disable-GEOM install When it's done, you can check that everything work by running the test_suite: $ cd src/unittest $ python test_all.py > Denis > Thomas
