HI Sam

That's how static libraries work. Static libraries aren't linked. They are 
simply packaged: the .o are simply packaged inside an archive (.a) and that's 
it. The dependencies are not recorded in the .a either.

When the final application is being linked, it must link to all the indirect 
dependencies of all its static libraries.

You'll need to write your own "link" step. You need to extract all the .o from 
libQtCore.a and libQtGui.a, add your own to the mix, then package them all 
together into your gui.a.

Take a look at ar's manual page to see how to extract files and how to create 
archives. Also, you should run ranlib after creating the .a file.
