Hello all,

has there been any experience with using the FFTs in the Intel MKL library? Im trying to compile CGYRO on the new Intel based supercomputer DAWN and there is no (currently) FFTW modules. The sysadmin says that linking to the MKL should work in the same way. I, of course, get errors (pasted below)

Regards

William
