ABINIT Discussion Forums

Hi, everyone.
When I tried to link intel-dfti to abinit-7.10.5, compiling error occurs as follows:
Have anyone successfully link dfti to abinit?

Replace src/52_fft_mpi_noabirule/dfti_fftrisc.finc with the file attached.

btw: The DFTI library provided by MKL should be activated only if you are compiling Abint with OpenMP threads (and indeed you are doing).
Remember to pass --enable-openmp to the configure script because there are sections of code inside Abinit that should be activated
when OpenMP is used.

fft_flavor=fftw3 supports both the true FFTW3 library as well as the FFT library provided by Intel and can be used
when OpenMP is not activated.
