Dear LAMMPS users,
I want to install peridynamics module of lammps on linux.I did first step- make yes-peri.It works fine .But when i wrote ‘make g++’ in src directory .It shows the following error.

g++ -g -O -DLAMMPS_GZIP -DLAMMPS_JPEG -DMPICH_SKIP_MPICXX -DFFT_FFTW -c angle_charmm.cpp
In file included from angle.h:18:0,
from angle_charmm.h:24,
from angle_charmm.cpp:20:
pointers.h:25:17: fatal error: mpi.h: No such file or directory
compilation terminated.
make[1]: *** [angle_charmm.o] Error 1
make[1]: Leaving directory `/home/vb/lammps-14Feb13/src/Obj_g++’
