Thanks. I had eventually succeeded by fixing my list of object files.

Because if you link with the shared libraries, the linker adds the entire ibraries (symbols) to its internal list of known symbols, and thus it an resolve all references. Check the order again, and then you'll be ble to link statically as well.
