Embedded Python interpreter and sockets

[wahn at acm.org]

Hi,

Here is a problem I came across and need some help with. I developed a
little Python script with some classes which runs standalone and
communicates with a database via sockets. So far everything works fine.
I also successfully embedded the Python interpreter into a plugin for a
commercial 3D package (in this case Houdini - http://www.sidefx.com/ -
using the HDK). I can use the interpreter to run Python commands and
get values back and forth between Python and C++. Anyway, I can also
successfully import SOME modules, but unfortunately not ALL. One
example would be the socket module which works fine in the standalone
version of my Python script but NOT from the embedded interpreter:

Traceback (most recent call last):
  File "<string>", line 40, in ?
  File "/swdevl/jwalter/Houdini/ROPS/HoudiniToMayaBake/damn.py", line
10, in ?
    import socket
  File
"/job/SYSTEMS/3PS/python/2.4.1/linux_intel//lib/python2.4/socket.py",
line 45, in ?
    import _socket
ImportError:
/job/SYSTEMS/3PS/python/2.4.1/linux_intel/lib/python2.4/lib-dynload/_socket.so:
undefined symbol: PyObject_GenericGetAttr

Other modules which get imported before just work fine (e.g. re and
string) ...

The Python library gets linked into the plugin DSO as a static library
... Any ideas what's going wrong and why?

Cheers,

Jan
