[daschuer]

No idea. Is this issue still pending?

[improvethings]

yes, I still have not resolved.

[daschuer]

Please share the complete console output. With VERBOSE=1

Error look probably similar on linux mint 22 :

[daschuer]

You link to "/usr/lib/libfftw.so" but you need to link to "/usr/lib/libfftw3.so" maybe removing fftw-dev does the trick.

[daschuer]

A fix is here: #34

[kikoucalou]

Effectively removing completly fftw-dev and fftw2 does the trick.
It build and run nicely now on Linux mint 22.

Thanks
