boost_python3 libraries not built correctly

[lbotsch]

The boost_python3 library uploaded to nuget.org (https://www.nuget.org/packages/boost_python3-vc140/) seems to be compiled against the wrong python version. The libraries

• boost_python3-vc140-mt-1_64.lib
• boost_python3-vc140-mt-gd-1_64.lib

export the symbol

struct _object * __cdecl boost::python::detail::init_module(char const *,void (__cdecl*)(void))

when they should export

struct _object * __cdecl boost::python::detail::init_module(struct PyModuleDef &,void (__cdecl*)(void))

See boost/python/module_init.hpp:

#  if PY_VERSION_HEX >= 0x03000000
BOOST_PYTHON_DECL PyObject* init_module(PyModuleDef&, void(*)());
#else
BOOST_PYTHON_DECL PyObject* init_module(char const* name, void(*)());
#endif

Make sure you actually compile boost_python3 for python3

Binaries for 1.64 were taken from https://sourceforge.net/projects/boost/files/boost-binaries/1.64.0/

Switch to 1.65 should solve the problem.
