Hi, how do you distribute ctypes based modules on a linux machine ? What does your setup.py look like ? I have to copy my shared library to /usr/lib or another common place, but I would prefer .../site-packages/... In the latter case I think I have to modify LD_LIBRARY_PATH oder some ld.so.conf configuration file. So, what is the prefered method for this task ? Greetings, Uwe -- Dr. rer. nat.
