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

Hi Terry,

the sybase module is not linked to the freetds libraries, that is why 
there are some undefined symbols.

This is probably because the setup.py script is not looking with the 
correct name for those libraries.

Could you please send me privately the list of files installed by your 
freetds package or the result of the following command:

ls /usr/lib/lib*blk* /usr/lib/lib*ct*  /usr/lib/lib*cs* \
/usr/lib/*libsybtcl* /usr/lib/lib*insck* /usr/lib/lib*comn* \
/usr/lib/lib*intl*

regards
