Sorry guys, library loading of a freezed binary is different to interpreter
mode. This is a bug in freeze, or at least an undocumented missing feature of
freeze. This is no side discussion.
And, in Python 3.2 this was working! As described above, just

Same issue with external libraries under (pachted) Python 3.4.0 final on Ubuntu

The shared library is not linked into the resulting binary

Yes. This is why (at least in Python 3.2) it must be in the right path
(subdirectory), see above.

Right, because PyRun uses freeze and freeze currently does not work

The only other freeze tool I know for Pyhton3 code is cx_freeze. I would

As for the failure when importing psycopg2, my guess is that the freezing of

I agree that it makes no sense to define __file__ for frozen modules.
Originally they did because that was the only way to tell if a module was a

As mentioned, the ABI issues are being handled in issue11824. I believe the
