Did you try any of examples in

        example/qt/qt3

and if so, what errors did you get?

This says to compile a file called A_moc.cpp, and such file does not
exist, and there's nothing to say how it should be built. Something like:

        lib LibA : A.cpp A.h /qt3//qt ; 

is what you're after, but really, start by trying the examples.
