What is happening here is that each shared library has a private -rpath setting. If a library has dependancies, it uses its own -rpath to search for the dependant library. This means that when you link the shared lib (libqt?) you must provide the correct -rpath. Life might be easier if rtld searched using the main program's rpath if the search with the shared lib's rpath failed. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
