So far I understood that this seems not to be possible. Do > you have any ideas or hints on this topics? You've already received some good suggestions. I'll add that ctypes is a bit slow in CPython. Also, you might want to try one or more of the following before resorting to a less-productive language like C++: 1) writing in Cython+CPython (as opposed to wrapping C++ with Cython) 2) using numba+CPython (It's a pretty fast decorator - I've heard it's faster than Cython) 3) shedskin (translates implicitly static Python to C++) 4) pypy (Python with a JIT - ignore RPython) Here's a link I've been maintaining about ways of speeding up Python: http://stromberg.dnsalias.org/~strombrg/speeding-python/ HTH -- https://mail.python.org/mailman/listinfo/python-list
