Dear all, Thank you for suggesting me about fftw compilers. Now i installed fftw-3.3.2 succesfully, But i got same error again. Here i am giving complete details F77=ifort FC=ifort MPIF90=mpiifort cc=cc Serial
ichecked libfftw3f.a and libfftw3f_mpi with " nm /applications/ice/fftw/lib/libfftw3f_mpi.a | grep -e f77" ;;there are no "_" in this file.
