How to link the BLAS library in mkl to compile other packages

HUANGK — Sun, 03 Apr 2022 17:15:34 GMT

I want to compile the ARPACK++ library, and I downloaded the Intel Fortran Compiler to compile the library. During the compilation process, I was prompted that the BLAS library could not be found. Isn't there a BLAS and LAPACK library in MKL? Why can't I use CMAKE to compile ARPACK directly?

Below is my detail page information

Your advice is invaluable to me, thank you for your help.

Hi,

Thanks for reaching out to us.

>>Isn't there a BLAS and LAPACK library in MKL?

Yes, Indeed they are part of MKL library.

This oneMKL library is part of oneAPI Base Toolkit but not HPC Toolkit.

So, could you please confirm if you have downloaded the oneAPI Base Toolkit first?

Also, we suggest you try compiling the ARPACK++ library in the Intel oneAPI command prompt where the setvars script is initialized automatically which will ease the process of finding and linking with necessary Intel components accordingly.

A quick check from our end shows that BLAS/LAPACK was found when trying to compile the arpack++ library in Intel oneAPI command prompt.

You can also do it from the normal windows command prompt but you need to run the setvars.bat file which is under this location C:\Program Files (x86)\Intel\oneAPI manually before starting to build the arpack++ library.

Hope the provided information helps.

Regards,

Vidya.
