[vtkusers] VtK 7, python3.4 build error

[Matthew Cragun]

David,

thanks for the response.

To provide some additional information, I have tried using python3.5
binaries straight off of python.org as wells as my anaconda installation.
Both give me the same error.

The variables I have set using ccmake and standard python are:


PYTHON_EXECUTABLE =
/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5
PYTHON_INCLUDE_DIR =
/Library/Frameworks/Python.framework/Versions/3.5/python3.5m
PYTHON_LIBRARY =
/Library/Frameworks/Python.framework/Versions/3.5/lib/libpython3.5.dylib


The contents of the lib folder are:
libformw.5.dylib    libmenuw.5.dylib    libncursesw.5.dylib
libpanelw.5.dylib   libpython3.5.dylib  pkgconfig
libformw.dylib      libmenuw.dylib      libncursesw.dylib   libpanelw.dylib
    libpython3.5m.dylib python3.5


Thanks,

Matt
