Real-time pitch detection using FFT

I'm trying to do real-time pitch detection using C++. I'm testing some code from performous (http://performous.org/), because everything else hasn't worked for me. I know for sure that this works, but i just cant get it to work. I've been trying this for a few weeks now, and I haven't been able to get any pitch detection code working.

Instead of using input from the mic, you should create data of a known single frequency and run that through the program and see if it gets you the correct result. Then you can add harmonics to it and see if that works. Real world data is just too variable for initial testing.
