Re: [openbabel-scripting] ImportError: dynamic module does not define init function (initopenbabel)

[Noel O'B. <no...@ca...>]

Hello Seth,

First of all, as the OB scripting modules in particular are young and
under active development, you may want to consider using the CVS version
of openbabel rather than the last release. (You also will have the
chance to test out the pyopenbabel module as somewhat described on the
openbabel website)

To answer your question, this bug has been fixed in CVS. It is caused by
Python's confusion between openbabel.so (a C extension) and openbabel.py
in /usr/lib/Python2.4/site-packages (on my system).

What you need to do is:
(1) Change "import openbabel" to "import _openbabel" at the start of
your own openbabel.py (in openbabel/scripts/python)
(2) change Extension('openbabel' to Extension('_openbabel' in
openbabel/scripts/python/setup.py.
(3) remove /usr/lib/Python2.4/site-packages/openbabel.so
(4) rerun "python setup.py install"
(/usr/lib/Python2.4/site-packages should now contain _openbabel.so and
openbabel.py)

I may have missed something here, and if so, I recommend moving to the
CVS version.

Please let us know if you have any more problems/questions with the
scripting module as we are keen to improve it.

Regards,
 Noel
