I checked the style_kspace.h file in the src folder. The libraries you mentioned
were there:
#include "ewald.h"
#include "ewald_n.h"
#include "pppm.h"
#include "pppm_tip4p.h"
I remade LAMMPS again after installing the ewald/n package. I made sure everything
was fine. After installing the ewald/n package, the *.cpp and *.h libraries were in
the src folder, but nothing changed: I got the same error messages. However, the
Windows executable works in my laptop. I have made the openmpi version of LAMMPS,
just in case it helps.
Any other suggestion, please?
