No its not but its located in my program folder but I did a export command before: LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:.

so it should be find. without that export command I get ./MedApp: error while loading shared libraries: libqt.so.2: cannot open shared object file: No such file or directory

and the libqt.so.2 is linked to my self compiled lib.

enclosed you can find the output of ldconfig -v

Hmm, as wysota said, your program does not find the qt lib. Or maybe your lib does not find a lib to which it has a dependency. You could try 'ldd libqt.so' to see if all dependencies are met. Else I'd try the ugly way and move the whole libqt* stuff into /usr/lib and do a 'ldconfig -v'. If this still not work I am out of my remote debugging options.

It does load the library, it seems. It also seems the library does not have the required symbols.

Which should be impossible. Even Qt 2 knew QWidget. :-)
I suppose it is a unmet dependency for libqt.so.2

Is it possible that I upload my program and one of you guys can try it to make it run? because I really need some screenshots for my bachelor thesis of this prog. it would be very kind. please let me know!
