Dear all, my name is Alex and I am a postdoc at the University of Alberta, Edmonton, Canada. I am working with an in-house opensource code that uses boost to wrap C++ code with Python. In the latest version of our code, one has to download boost manually and compile it. I have tried wot two different versions (1.59 and 1.60) and I can compile them with python 2.7. However, if I try to compile it using either Python 3.3 or 3.5, I always get the same error: "./boost/python/detail/wrap_python.hpp:50:23: fatal error: pyconfig.h: No such file or directory # include <pyconfig.h>" I have been looking for this error for a while, but I have not been able to find a proper solution. I wonder if you could help me on this matter. Thank you very much for your attention. Best regards, Àlex
