What do we miss ?

Thanks!

/usr/include/c++/4.8.2/bits/memoryfwd.h line 50 before std has a keyword namespace.

I wonder if pycparser requires .hpp extension for the header files to be processed as C++ and not as C.

Hello, It's been a long time since I worked on this library and I didn't write most of the code. I don't think I'll be able to help you much. Though from what I remember, autopxd cannot not handle C++ code.

thank you @gabrieldemarmiesse for prompt response

this error seems to happen in pycparser so I will check there too
