3D DFT

I am trying to do a 3D FFT in MKL 11.3, but its not working for me... most likely I am doing something wrong, but I am at a loss.

I get an error when I attempt to call DftiCommitDescriptor.  I tried two different cases and got two different errors.  My code is shown below... Any help would be appreciated!

#include <mkl.h>
#include <stdio.h>

int main()

{

  DFTI_DESCRIPTOR_HANDLE dh;

  float *data;
  MKL_LONG sz[3];
  MKL_LONG dim = 3;
  int val;
  int error_code;

  sz[0] = 128;
  sz[1] = 128;
  sz[2] = 128;

  dim = 2;
  error_code = DftiCreateDescriptor(&dh, DFTI_SINGLE, DFTI_REAL, dim, sz);
  error_code = DftiCommitDescriptor(dh);
  printf("error_code: %d\n", error_code);

  dim = 3;
  error_code = DftiCreateDescriptor(&dh, DFTI_SINGLE, DFTI_REAL, dim, sz);
  error_code = DftiCommitDescriptor(dh);
  printf("error_code: %d\n", error_code);

  printf("%s\n", DftiErrorMessage(error_code));

  dim = 3;
  error_code = DftiCreateDescriptor(&dh, DFTI_SINGLE, DFTI_REAL, dim, sz);
  error_code = DftiSetValue(dh, DFTI_CONJUGATE_EVEN_STORAGE, DFTI_COMPLEX_COMPLEX);
  error_code = DftiCommitDescriptor(dh);
  printf("error_code: %d\n", error_code);

  printf("%s\n", DftiErrorMessage(error_code));

}

Note that the first call works (dim is set to 2).

The second call fails (only difference is that dim is 3), indicating that the functionality is not implemented.

I read in the documentation that I should use DFTI_CONJUGATE_EVEN_STORAGE <- DFTI_COMPLEX_COMPLEX, so I tried this as well (third call), but it failed with the error "Inconsistent configuration parameters". 

The output I get is as follows:

error_code: 0
error_code: 6
Intel MKL DFTI ERROR: Functionality is not implemented
error_code: 3
Intel MKL DFTI ERROR: Inconsistent configuration parameters
