I am trying to start a debugging session in QtCreator, and every time I get a message about the debugging helper not being configured. I have tried this with QtCreator 2.4 and 2.5

I had been using 2.5 as a standalone install of QtCreator, and I tried to manually point to QMake, but it wouldnt give me the option there to build the gdb debug helper. I downloaded the SDK, and in QtCreator 2.4 it did autodetect 3 versions of qmake (Desktop, hartmann and similator). I built the gdb debugger helper for Desktop, and restarted my debugging session to find out it still asks me. What am I doing wrong?

Thanks
