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?
