   Of course this is nonsense.  Alfred confuses several different
   issues that lead to a particular result.

The GPL FAQ agrees with me.

| Yes.

   While the SDK library is not derived from Qt, the complete example
   program is derived from both SDK library and Qt.

If the SDK library links to a GPL library/program, then it becomes a
deriviate work.  There is not much to argue about.  Please read the
GPL FAQ, and please read the GPL.

   So the net effect is that you have a problem, even though it is
   different from the problem Alfred proposes.

Simply false, please refrain from spreading lies.
