Hi, The Fast Fourier Transform package of the West fftw is still in version 2.1.5-8 in FC Extras. Is there a reason that the updated and apparently incompatible version 3.0.1 is not available? It used to be available as fftw3 under Matthias Saou's freshrpms. Many thanks and best wishes! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
