Hello,
It appears that the ctypes_intergration stuff in pyplusplus is not 64bit
safe. The general basics is that it is casting a void* to a
boost::uint32_t (which can't fit a void* on 64bit platforms).
See the error below,

I ended up changing the code in
pyplusplus/code_repository/ctypes_intergration.py from boost::uint32_t
to std::size_t.
It seems to compile and work now...
Is that the correct solution?
