Well, you could not guess that salomegeometry was required instead of the whole Salomé project. > Ok I compiled and installed salomegeometry without any problem. > Now I am trying to compile pythonOcc trunk (as you told me 0.3 doesn't > support 64 bits- yet the -march=X86_64 error remains but easy to solve). > I think it's actually better to compile pythonOCC trunk. It's compliant with the latest rev. of salomegeometry trunk. Maybe you have to add '-march=X86-64 -m64' as an extra compile arg. You can have a look to the environment.py script and copy/paste the way I solved the 64 bits issue on MacOSX. > It quickly get on a weird casting error - see attached log file. > Strange. What version of swig do you use? Everything goes fine with 1.3.39 but I noticed an error with 1.3.40.
