I'm running RHEL5 with QT4.2.1 with QtCreator 1.3.1 and have been able to build the debugging helpers. QStrings show up nicely in the debugger.

I decided to try out the newest QtCreator 2.3 Beta and also installed a separate QT4.7.3. I have the qmake path set to QT4.7.3 and QTCreator does find it. I can build QML Debugging Library and Observer but for Dump it says "Cannot be compiled." and GDB Helper, it says "Not Needed". When I debug, the QStrings do not show up nicely.
I also added QT4.2.1, but under helpers, they all say "Cannot be compiled."
Is there a way to manually compile these?
