Should k3b try to dlopen 'libcdda_paranoia.so.0' > instead? Yes! The suffix '0' denotes the library's SONAME. As long as it does not change, different versions of the lib must be binary compatible. OTOH, if it _does_ change, your program linking against it is likely to fail. This allows having several (major) library versions installed in parallel, but enforces that only one version of a development package can be installed so that new packages are urged to use the most recent version.

I guess, yes. > Where can i learn more about the naming of share object files? When I built my first library package, I consulted the 'Debian Library Packaging Guide' [1]. Not complete yet, but already very helpful. But actually, it isn't that difficult: packages containing shared libraries provide them with their soname as suffix, -dev packages add the corresponding symlink without a soname. BTW: Corrections appreciated, I'm still quite new to Debian.
