You're right, the depency of Construct.py with GEOM should be removed. It's a recent commit that is not consistent with the optional GEOM wrapper. > but get now a segmentation fault: > testHash (wrapper_features_unittest.TestWrapperFeatures) ...

It's equal to 2^32-1 on 32bit platforms, 2^64-1 on 64bit. This is computed from the file environment.py ( https://github.com/tpaviot/pythonocc/blob/master/src/wrapper/environment.py) called when compiling pythonocc from the setup.py script. The __hash__() method does not take any argument. It is a wrapper for the HashCode method and is is defined in the SWIG file as: %extend Standard_Transient { Standard_Integer __hash__() { return $self->HashCode(__PYTHONOCC_MAXINT__); } }; (see for instance the file Standard.i at https://github.com/tpaviot/pythonocc/blob/master/src/wrapper/SWIG/linux_darwin/Standard.i ). > Denis > Thomas
