I installed mpi and gave the right path. I am getting the following error.

make[1]: Entering directory /home/arun/Downloads/lmp/lammps/src/Obj_g++' g++ -g -O -DLAMMPS_GZIP -DLAMMPS_JPEG -DMPICH_SKIP_MPICXX -I/home/arun/Downloads/lmp/mpich2/include -DFFT_FFTW -I/home/arun/Downloads/lmp/fftw2/inlcude -I/home/arun/Downloads/lmp/jpeg/include -c ../fft3d_wrap.cpp In file included from ../fft3d_wrap.h:18:0, from ../fft3d_wrap.cpp:15: ../fft3d.h:212:18: fatal error: fftw.h: No such file or directory #include "fftw.h" ^ compilation terminated. make[1]: *** [fft3d_wrap.o] Error 1 make[1]: Leaving directory /home/arun/Downloads/lmp/lammps/src/Obj_g++’

Same type of error than before, but for a different library. Why don’t you just use the internal FFT library?

You obviously have no experience compiling from source.
Please find somebody local that does and teaches you these things.

Also, you still didn’t answer my question about what it is that you are missing.

Also, please read Section_start.html of
the manual about building LAMMPS.
