Re: [Open Babel] python bindings broken in 2.2.1 on 64 bit linux

[Noel O'B. <bao...@gm...>]

Sorry for the delay in replying. openbabel-scripting is a good place
to send emails about the Python bindings BTW.

I'm afraid I can't test the problem as I don't have access to a 64 bit
system. However, it is possible it is due to OpenBabel's use of SWIG
1.3.37, which has several changes to how it handles Python in
particular (some good, some unexpected). You could try recompiling OB
and its bindings using the very latest version of swig (1.3.39) or the
earlier one (1.3.36). (Put swig on the path and use ./configure
--enable-maintainer-mode).

I would be very interested to know if this helps.
