Hello,

I am using Window 10, with 8 GB ram. Moreover, I am using Intel OneApi with Intel OneApi Fortran HPC compiler, the latest update. I have inherited a Fortran code that I want to add more elements to fit my job. But in this code, I have some diffulties. First, I have to include "fftw" library. I have gone on their website, but I didn't help me so much. The second problem is corcerning an external function call DGEMM, which I think is linked to MKL, which I haven't yet installed.

Here is a screenshot to illustrate my thought.

Hi DIALLO Mahamadou Lamine Ousmane,

>>The second problem is corcerning an external function call DGEMM, which I think is linked to MKL, which I haven't yet installed.

Yes, 'FFT' and 'DGEMM' come under Intel oneMKL. So, we request you to install oneMKL latest version using either of the links

For Intel oneAPI Base Toolkit (OR) For single component (oneMKL)

And also please refer to the below link for Linking Your Intel Visual Fortran Project with oneMKL

https://www.intel.com/content/www/us/en/docs/onemkl/developer-guide-windows/2023-2/auto-link-intel-visual-fortran-proj-with-onemkl.html

If the issue still persists please get back to us by providing a complete sample reproducer and a complete error log.

Thanks and Regards,
