[openbabel-scripting] import error

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

Dear all,

After swapping "_openbabel.so" for "openbabel.so" in setup.py:
----------------------start of diff
7c7
< obExtension = Extension('openbabel',
---
> obExtension = Extension('_openbabel',
----------------------end of diff

and after setting LD_LIBRARY_PATH to include /usr/local/lib, I still
cannot import openbabel:
----------------------quote
>>> import openbabel
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: dynamic module does not define init function
(initopenbabel)
----------------------unquote

However, if I go to openbabel/scripts/python, and import the
openbabel.py directly, I have no problems!

Can anyone explain this?

Regards,
Noel

    _openbabel = swig_import_helper()
  File "/usr/local/lib/python2.6/site-packages/openbabel.py", line 87,
in swig_import_helper
    _mod = imp.load_module('_openbabel', fp, pathname, description)
ImportError: /usr/local/lib/python2.6/site-packages/_openbabel.so:

You need to compile with Eigen2 as described in the docs.

You are getting the error because you still have openbabel.so in your
search path. so files have precidence over .py files.
