[Python-sybase-misc] "ImportError: .../sybasect.so: undefined symbol: cs_config"

[Terry B. <te...@te...>]

Hi,

I'm happily running the Python-Sybase module on Python 2.5.2, FreeTDS
0.82, Debian Lenny/686. Everything work with no problems.

However, when I build the module on an equivalent 64-bit system Python
2.5.2, FreeTDS 0.82, Debian Lenny/AMD64, I encounter the following
runtime error when running import Sybase:

Traceback (most recent call last):
  File "/srv/ipdb/bin/ndor_latest", line 3, in <module>
    import Sybase
  File "/usr/lib/python2.5/site-packages/Sybase.py", line 11, in <module>
    from sybasect import *
ImportError: /usr/lib/python2.5/site-packages/sybasect.so: undefined
symbol: cs_config

Any clues as to what might be happening would be gratefully received.


All the best,

Terry
