I would suggest you make it work with qmake first, and then try to compile it by hand. Good luck!
It seems that -shared option of g++ just turns off all errors, ignores them. So I try to link without -shared option and look at errors.

EDIT: Now I use these commands.
g++ -c -pipe -O3 mb.cpp
g++ -Wl,-rpath-link,/usr/lib -L/usr/lib -lQtCore -lQtGui -lQtDBus -lpthread -lzbar -shared mb.o -o mb.so

It still says "Could not load"

When I remove -shared from the second line, it says "undefined reference to 'vtable for class'". If anybody knows how to resolve it, he is welcome (there are neither constructors nor destructors in the two classes).
