Hello lammps users,
I’m trying to compile lammps11-Aug17. When I do “make mpi” in /src, I got the error:

http://lammps.sandia.gov/doc/Section_start.html#step-6
start by compiling LAMMPS *without* FFTW support (which is how
Makefile.mpi ships by default).
the performance differences of LAMMPS due to the choice of FFT are quite
small and are often irrelevant unless you run on extremely large machines
and specific inputs.
