IMHO this can't possibly work. I assume that you want to create a shared library from a set of static libraries, right? Well, due to the nature of static linking, you'll need a source file that pulls in all the symbols that you want in your final library, otherwise nothing will happen.

What is it exactly you are trying to achieve?
