Finding an Alternative to FFTW for 2D Complex FFTs

[foton7]

Does anyone know a good free library to do Fourier Transforms (FFT or DFT). I know FFTW but I'm having some problems with it. I want an alternative that do FFT in two dimensions with complex numbers. The libraries I have found doesn't fulfill this requirements.

Thank you

FFTW is the standard. What problems are you having?
