[Insight-users] FFTw

[Lodron, Gerald]

Hi

Yes, i need it for some registration algorithms.

The problem is that i cannot build FFTW on my own, when i download FFTW source for windows i did not find any Cmake files and i do not know how to build that stuff without a Cmake or a Project file (so i would recommend the final libraries for me, but if you can explain me in detail how to build it i will try, i have no idea).

Ok but i think that .lib is the Windows equivalent to .so in Linux so it should be

> FFTWD_LIB = libfftw3.lib
> FFTWD_THREADS_LIB
> FFTWF_LIB = libfftw3f.lib
> FFTWF_THREADS_LIB

The only question is, where are my threads lib??? Are they needed??? 

Is it possible that i am the only windows fftw and itk user????

I would be very thanksfull for any help!

Best regards,
Gerald Lodron

Hi Gerald,

Are you doing this in order to use FFTW from ITK ?

If so, once you have build FFTW, you should simply rerun CMake to configure ITK and turn on the CMake
option:

                  USE_FFTWD and/or
                  USE_FFTWF


Once you do that CMake should find the FFTW libraries.

As an example, this is what I have on one of may Linux builds that has FFTW enabled:

FFTWD_LIB:FILEPATH=/usr/lib/libfftw3.so
FFTWD_THREADS_LIB:FILEPATH=/usr/lib/libfftw3_threads.so
FFTWF_LIB:FILEPATH=/usr/lib/libfftw3f.so
FFTWF_THREADS_LIB:FILEPATH=/usr/lib/libfftw3f_threads.so

(Note that I didn't have to type these paths myself, CMake found them,... maybe because FFTW was installed in the system directories...)


   Let us know if you find  any problems,


         Thanks


                Luis
