Like Matthew said - you should probably find a Python list/forum for these
questions.

If python is built in 64bit mode then it HAS to use the 64bit Sybase libs.
However I suspect that the python Sybase glue code hasn't been modified to
handle the changes required to link/build with the 64bit libs - in
particular including the -DSYB_LP64 command line arg to gcc when compiling
the C code, and linking with the xxx64 version of the libs.

Subject:    python and sybase


Hi,

I am running linuxamd64 with SLES 9.3.

I can't get the python to import Sybase after it installs with no errors.
I tried editing the setup.py as is suggested and changing libraries from ct
to ct64.  Other posts say to try sybct, I tried that too. That didn't help
with OCS-15_0(64-bit).  My theory now is that Dave build python - sybase to
work with 32-bit sybase OCS even though python 2.3.5 itself uses 64-bit.
Below is a screenshot showing python's sybase module, sybase-0.37
installing
with out error.  I'm not sure what to try at this point.

Should I dump OCS and can I get python to import sybase with just freetds
and not involve OCS?
Should I work on getting a 32-bit version of OCS from $ybase?

:/usr/local/src/sybase-0.37> vi setup.py
:/usr/local/src/sybase-0.37> python setup.py build_ext -D WITH_THREADS
running build_ext
:/usr/local/src/sybase-0.37> python setup.py install
running install
running build
running build_py
