Undefined reference to fftw3 functions

[Navdeep_Rana]

I installed mkl wrappers for fftw i.e. fftw3xc, fftw3xf, fftw3x_cdft with
 

make libintel64 INSTALL_DIR=$MKLROOT/lib/intel64

and I am sourcing

$MKLROOT/bin/mklvars.sh intel64
$INTELPATH/compilervars.sh intel64

but I end up getting the following undefined error. Can anyone help?

obj/fftw3_mpi.o: In function `fftw3_mpi_mp_create_fftw3_plans_':
fftw3_mpi.f90:(.text+0x9ce): undefined reference to `fftw_mpi_plan_dft_r2c_2d_f03'

This is a linking error. Can you post the link command?

Yes I figured that out. Had to link using -lfftw3x_cdft_lp64 -lfftw3xf_intel -mkl instead of -mkl.

It now compiles but on runline runtime shows the following error.

Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers

Are you sure that the directory where your linked libraries are located, is in the DYLD_LIBRARY_PATH?

Okay this is new. I never knew of any such variable, but I did set it up and I get the same error.
