Hi,
I am not sure if the following observation is helpful - but for any case here it comes...
On my system (Debian etch) the extension `.so.0' is used for some libraries - and not the extension `.so' cm-gtk was searching for.
Example:
ls -la /usr/lib/libgtk-x11-2.0.so ls: /usr/lib/libgtk-x11-2.0.so: No such file or directory
ls -la /usr/lib/libgtk-x11-2.0* lrwxrwxrwx 1 root root 26 2006-10-27 23:30 /usr/lib/libgtk-x11-2.0.so.0 -> libgtk-x11-2.0.so.0.800.20 -rw-r--r-- 1 root root 3039524 2006-10-14 06:29 /usr/lib/libgtk-x11-2.0.so.0.800.20
In order to load the libraries I made some changes to my version of the code:
- cm-gtk now searches the libraries using both extensions - the list of extensions searched for is customizable by setting the variable *gtk-libext* to something different. current value: #+:darwin '("dylib") #-:darwin '("so" "so.0"))
Thanks for your wonderful program!
Best wishes, Dietrich
Here come my changes...
