That is indeed what I did. A do get .cpp file. The thin is that if I run setup, the library is again swigged but without the -c++ option (see original post) but honestly, I don't know what to do after I have the .cpp file. I could not find any docs that explained clearly how to compile if you are using C++ The only thing I found was that it was not so straightforward So, again, any help is very much appreciated -- http://mail.python.org/mailman/listinfo/python-list
