I am a new user of LAMMPS and I have a problem building the code. While following the instructions in the manual, at the beginning, I got an error message: catastrophic error: could not open source file “mpi.h”
I looked for the “mpi.h” and copied it in the “src”. Now, I am getting another error message: catastrophic error: could not open source file “fftw.h”
I could not find that file anywhere in the package.
I would appreciate if any one can guide me thorigh this issue.
The manual and the lo-level Makefiles like src/MAKE/Makefile.g++
explain about how to use MPI and the FFTW library. You should
leave mpi.h where it is on your system and point to it in the Makefile.*.
