Thankyou for the reply. I am using opensuse 13.1. I installed mpi and gave the right path. Now I am getting the following error. Somehow the makefile is not pointing the right path and my make file looks like.
g++ = RedHat Linux box, g++4, MPICH2, FFTW
SHELL = /bin/sh

compiler/linker settings
specify flags and libraries needed for your compiler
CC = g++
CCFLAGS = -g -O # -Wunused
SHFLAGS = -fPIC
DEPFLAGS = -M
LINK = g++
LINKFLAGS = -g -O
LIB =
SIZE = size
ARCHIVE = ar
ARFLAGS = -rc
SHLIBFLAGS = -shared
---------------------------------------------------------------------
LAMMPS-specific settings
specify settings for LAMMPS features you will use
if you change any -D setting, do full re-compile after “make clean”
LAMMPS ifdef settings, OPTIONAL
see possible settings in doc/Section_start.html#2_2 (step 4)
LMP_INC = -DLAMMPS_GZIP -DLAMMPS_JPEG
MPI library, REQUIRED
see discussion in doc/Section_start.html#2_2 (step 5)
can point to dummy MPI library in src/STUBS as in Makefile.serial
INC = path for mpi.h, MPI compiler settings
PATH = path for MPI library
LIB = name of MPI library
MPI_INC = -DMPICH_SKIP_MPICXX -I/home/arun/Downloads/lmp/mpich2/include
MPI_PATH = -L/home/arun/Downloads/lmp/mpich2/lib64
MPI_LIB = -lmpich -lmpl -lpthread
FFT library, OPTIONAL
see discussion in doc/Section_start.html#2_2 (step 6)
can be left blank to use provided KISS FFT library
INC = -DFFT setting, e.g. -DFFT_FFTW, FFT compiler settings
PATH = path for FFT library
LIB = name of FFT library
FFT_INC = -DFFT_FFTW -I/home/arun/Downloads/lmp/fftw2/inlcude
FFT_PATH = -L/home/arun/Downloads/lmp/fftw2/lib64
FFT_LIB = -lfftw
JPEG and/or PNG library, OPTIONAL
see discussion in doc/Section_start.html#2_2 (step 7)
only needed if -DLAMMPS_JPEG or -DLAMMPS_PNG listed with LMP_INC
INC = path(s) for jpeglib.h and/or png.h
PATH = path(s) for JPEG library and/or PNG library
LIB = name(s) of JPEG library and/or PNG library
JPG_INC = -I/home/arun/Downloads/lmp/jpeg/include
JPG_PATH = -L/home/arun/Downloads/lmp/jpeg/lib64
JPG_LIB = /home/arun/Downloads/lmp/jpeg/lib/libjpeg.la
