[OpenBabel-scripting] Python bindings on amd64 Linux

[richard a. <ric...@ya...>]

Has anyone gotten the Python Open Babel interface to
work on amd64 Linux? I'm using rev 1578 of the svn
trunk

When I try to import openbabel, I get the following
error

>>> import openbabel
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File
"/usr/lib64/python2.4/site-packages/openbabel.py",
line 3, in ?
    import dl
ImportError: No module named dl

I noticed a similar problem reported here, but no
solution:

http://sourceforge.net/mailarchive/message.php?msg_id=37015184

I had no problems either compiling or installing
pyopenbabel - just loading it in python.

My system does lack the python dl module, which as far
as I can tell is supposed to be standard. In googling
around, I found several references to the python dl
module being unstable on amd64 - and therefore not
available.

So - has anyone found a workaround to this problem?

I tried one: comment out the code responsible for
loading dl in the first place (openbabel.py):

if sys.platform.find("linux") != -1:
    import dl
    sys.setdlopenflags(sys.getdlopenflags() |
dl.RTLD_GLOBAL)

I can in fact import openbabel after doing this. The
problem is that when using OBConversion, none of the
formats are loaded:

>>> import openbabel
>>> c=openbabel.OBConversion()
==============================
*** Open Babel Error  in LoadFormatFiles
  /usr/local/lib/openbabel/cmlreactlformat.so did not
load properly
==============================

... and dozens more load errors after this one ...

thanks,
Rich
