Hello!

The APIs for FFT have been changed since quite some time ago. In the latest MKL (2024.1 release), the user would need to create a descriptor and optionally to make some subsequent changes to the descriptor to define the FFT to be computed. Then commit the descriptor, do the computation and finally free the descriptor. 

For details, please refer to the developer reference. Also, it is recommended to check the examples in the package,  $MKLROOT/share/doc/mkl/examples/examples_core_c.tgz. There is an example for 2D double complex FFT.
