Direct Migration

  1. Globally, replace the interface prefix fftw with the kml_fft prefix and the interface prefix fftwf with the kml_fftf prefix. If the macro definition constant defined in the FFTW header file is used, replace the FFTW prefix with the KML_FFT prefix. Replace #include <fftw.h> with #include <kfft.h>.
  2. Replace -lfftw/-lfftwf with -lkfft/-lkfftf in the compilation options.
  3. Add environment variables. /PATH_TO_KFFT indicates the KML_FFT installation path.
    export LD_LIBRARY_PATH=/PATH_TO_KFFT:$LD_LIBRARY_PATH
