I am trying to build NAS benchmarks using Intel MPI and below is the makefile that I am using.

#---------------------------------------------------------------------------

# SITE- AND/OR PLATFORM-SPECIFIC DEFINITIONS.

#---------------------------------------------------------------------------

# Items in this file will need to be changed for each platform.

#---------------------------------------------------------------------------

# Parallel Fortran:

# For CG, EP, FT, MG, LU, SP and BT, which are in Fortran, the following must

# be defined:

# MPIF77 - Fortran compiler

# FFLAGS - Fortran compilation arguments

# FMPI_INC - any -I arguments required for compiling MPI/Fortran

# FLINK - Fortran linker

# FLINKFLAGS - Fortran linker arguments

# FMPI_LIB - any -L and -l arguments required for linking MPI/Fortran

# compilations are done with $(MPIF77) $(FMPI_INC) $(FFLAGS) or

# $(MPIF77) $(FFLAGS)

# linking is done with $(FLINK) $(FMPI_LIB) $(FLINKFLAGS)

#---------------------------------------------------------------------------

# This is the fortran compiler used for MPI programs

#---------------------------------------------------------------------------

MPIF77 = gfortran

# This links MPI fortran programs; usually the same as ${MPIF77}

FLINK = $(MPIF77)

#---------------------------------------------------------------------------

# These macros are passed to the linker to help link with MPI correctly

#---------------------------------------------------------------------------

FMPI_LIB = -L/share/apps/intel/impi/5.0.2.044/intel64/lib -lmpi

#---------------------------------------------------------------------------

# These macros are passed to the compiler to help find 'mpif.h'

#---------------------------------------------------------------------------

FMPI_INC = -I/share/apps/intel/impi/5.0.2.044/intel64/include

#---------------------------------------------------------------------------

# Global *compile time* flags for Fortran programs

#---------------------------------------------------------------------------

FFLAGS = -O

#---------------------------------------------------------------------------

# Global *link time* flags. Flags for increasing maximum executable

# size usually go here.

#---------------------------------------------------------------------------

FLINKFLAGS = -O

#---------------------------------------------------------------------------

# Parallel C:

# For IS, which is in C, the following must be defined:

# MPICC - C compiler

# CFLAGS - C compilation arguments

# CMPI_INC - any -I arguments required for compiling MPI/C

# CLINK - C linker

# CLINKFLAGS - C linker flags

# CMPI_LIB - any -L and -l arguments required for linking MPI/C

# compilations are done with $(MPICC) $(CMPI_INC) $(CFLAGS) or

# $(MPICC) $(CFLAGS)

# linking is done with $(CLINK) $(CMPI_LIB) $(CLINKFLAGS)

#---------------------------------------------------------------------------

# This is the C compiler used for MPI programs

#---------------------------------------------------------------------------

MPICC = cc

# This links MPI C programs; usually the same as ${MPICC}

CLINK = $(MPICC)

#---------------------------------------------------------------------------

# These macros are passed to the linker to help link with MPI correctly

#---------------------------------------------------------------------------

CMPI_LIB = -L/usr/local/lib -lmpi

#---------------------------------------------------------------------------

# These macros are passed to the compiler to help find 'mpi.h'

#---------------------------------------------------------------------------

CMPI_INC = -I/usr/local/include

#---------------------------------------------------------------------------

# Global *compile time* flags for C programs

#---------------------------------------------------------------------------

CFLAGS = -O

#---------------------------------------------------------------------------

# Global *link time* flags. Flags for increasing maximum executable

# size usually go here.

#---------------------------------------------------------------------------

CLINKFLAGS = -O

#---------------------------------------------------------------------------

# MPI dummy library:

# Uncomment if you want to use the MPI dummy library supplied by NAS instead

# of the true message-passing library. The include file redefines several of

# the above macros. It also invokes make in subdirectory MPI_dummy. Make

# sure that no spaces or tabs precede include.

#---------------------------------------------------------------------------

# include ../config/make.dummy

#---------------------------------------------------------------------------

# Utilities C:

# This is the C compiler used to compile C utilities. Flags required by

# this compiler go here also; typically there are few flags required; hence

# there are no separate macros provided for such flags.

#---------------------------------------------------------------------------

CC = cc -g

#---------------------------------------------------------------------------

# Destination of executables, relative to subdirs of the main directory. .

#---------------------------------------------------------------------------

BINDIR = ../bin

#---------------------------------------------------------------------------

# Some machines (e.g. Crays) have 128-bit DOUBLE PRECISION numbers, which

# is twice the precision required for the NPB suite. A compiler flag

# (e.g. -dp) can usually be used to change DOUBLE PRECISION variables to

# 64 bits, but the MPI library may continue to send 128 bits. Short of

# recompiling MPI, the solution is to use MPI_REAL to send these 64-bit

# numbers, and MPI_COMPLEX to send their complex counterparts. Uncomment

# the following line to enable this substitution.

# NOTE: IF THE I/O BENCHMARK IS BEING BUILT, WE USE CONVERTFLAG TO

# SPECIFIY THE FORTRAN RECORD LENGTH UNIT. IT IS A SYSTEM-SPECIFIC

# VALUE (USUALLY 1 OR 4). UNCOMMENT THE SECOND LINE AND SUBSTITUTE

# THE CORRECT VALUE FOR "length".

# IF BOTH 128-BIT DOUBLE PRECISION NUMBERS AND I/O ARE TO BE ENABLED,

# UNCOMMENT THE THIRD LINE AND SUBSTITUTE THE CORRECT VALUE FOR

# "length"

#---------------------------------------------------------------------------

# CONVERTFLAG = -DCONVERTDOUBLE

# CONVERTFLAG = -DFORTRAN_REC_SIZE=length

# CONVERTFLAG = -DCONVERTDOUBLE -DFORTRAN_REC_SIZE=length

#---------------------------------------------------------------------------

# The variable RAND controls which random number generator

# is used. It is described in detail in README.install.

# Use "randi8" unless there is a reason to use another one.

# Other allowed values are "randi8_safe", "randdp" and "randdpvec"

#---------------------------------------------------------------------------

RAND = randi8

# The following is highly reliable but may be slow:

# RAND = randdp

When I try to build let's say EP benchmark ***make NPROCS=8 EP CLASS=C***, I get an error like

Can anybody please help me in resolving this issue?
