ofxFft: FFTW + KISS FFT wrapper

Hi!

I try to run example-basic over and over on Visual Studio2012, but always fail to do it.
These are my errors.

expected constant expression
'avgCol' : unknown size
cannot allocate an array of constant size 0

And they are in the same sentence:59 in ofxProcessFFT.cpp.
What should I do?
Thank you in advance for any advice

Ryota
