Hi, when I try to use TVirtualFFT I have the following error:

Error in <TUnixSystem::FindDynamicLibrary>: FFTW[.so | .dll | .dylib | .sl | .dl | .a] does not exist in..............
..........................
Error in <TVirtualFFT::FFT>: handler not found

  *** Break *** segmentation violation

If I run:

root-config --has-fftw3

the answer is “yes”. I don’t know what to do, please help me.

Hi,

There is some issues loading libFFTW.so. I guess if you do
gSystetm->Load(“libFFTW.so”) it will fail.
You might need to set correctly the LD_LIBRARY_PATH or you have a configuration issue

@moneta

gSystetm->Load(“libFFTW.so”) it will fail.

Yes, I have have an error if I run that command.

How can I set correctly the LD_LIBRARY_PATH?

Thanks,
Valerio
