1. When you do a major upgrade of your C++ compiler, you usually have to
recompile your C++ libraries like Qt.
2. You don't need designer or uic and I think you can tell Qt not to compile
them. It's strange that you have errors compiling them. Qt guys are more
accurate than we are and shouldn't make releases that don't compile with
newest gcc. Double-check that it's not your problem ( e.g. failed dependency
on something else like libstdc++ ).

That you are trying to use C++ programs and libraries compiled with old
compiler.
