Undefined symbol when importing ATK.Core Python module

>>> import ATK.Core
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    _mod = imp.load_module('_Core', fp, pathname, description)
  File "/usr/lib/python3.5/imp.py", line 242, in load_module
    return load_dynamic(name, filename, file)

    return _load(spec)
ImportError: /usr/lib/python3.5/site-packages/ATK/Core/_Core.so: undefined symbol: _ZN3ATK16OutPointerFilterIxEC1EPxilb

Note: I moved /usr/lib/site-packages/ATK to /usr/lib/python3.5/site-packages since /usr/lib/site-packages is not a valid Python module directory on non-debian-based systems.

That's intriguing. I'll try to reproduce the issue.
You can set the Python specific folder by using PYTHON_INSTALL_FOLDER

OK, I guess the issue is with the differences between long and long long on Linux. I should be able to do something better now.

[mbrucher]

Let's say this is closed until proven otherwise ;)
If it compiles, now it should be OK, as the SWIG wrappers explicitly uses the same types as the C++ instantiations.

Yes, this seems to have fixed the issue.
