I'd like to know whether it comes from my binaries or your system. According to the trace, the error seems to come from the line: Symbol not found: __cg_jpeg_resync_to_restart Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib Expected in: /usr/local/lib/libJPEG.dylib The _TopoDS.so dynamic library is not linked to libJPEG.dylib. So I suspect a conflict somewhere with the libraries you installed. The default libTIFF.dylib is linked to /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib (on my machine). You have another libJPEG.dylib in your /usr/local/lib, and they may conflict. Googling "Symbol not found: __cg_jpeg_resync_to_restart" will give you hundreds of answers! A possible fix seems to force the system to look for libJPEG.dylib in the default dir first: set LIBRARY_PATH and DYLD_LIBRARY_PATH=/System/Library/Frameworks/ApplicationServices.framework/Versi ons/A/Frameworks/ImageIO.framework/Versions/A/Resources:/whatever (see http://osdir.com/ml/apple.fink.tracker/2005-05/msg00182.html). Just another question: since this problem may come from X or the Window Manager, did you try to only 'import OCC.TopoDS' from your python prompt and check the result? Is the trace the same? > > > -- > Bill Bedford > Thomas
