fatal error: fftw.h

Dear lammps users,

I’m trying to install lmp_openmpi (lammps-8Jul13) on our server computer, but I have the blow error:

“fatal error: fftw.h: No such file or directory #include “fftw.h””

“make[1]: *** [fix_phonon.o] Error 1”

I have searched about fftw.h, but I could not find a suitable result. Do I have to write it myself or should I download somewhere?

Thanks in advance

FFTW is an FFT package - you can google it.

if it is not installed on your system, you shouldn’t

be trying to build LAMMPS with FFTW support.
