fatal error: 'mkl.h' file not found

Hi, this the first time I’m trying to run C++ code in command line and I need to use mkl.h library. I have downloaded the oneAPI base toolkit but I don't know how to make the command line knows the downloaded library.

I am using terminal on macos system.

Hi,

Thanks for reaching out to us.

You can follow the link line advisor suggestions for successfully compiling and linking your application with MKL.

Link Line advisor tool helps you to get the compiling and linking options with respect to your environment.

Here is the link for the link line advisor tool:

Another way is to simply include the -qmkl option in your command

icpc -qmkl <filename.cpp>

(icpc is the Intel compiler for C++ language and you can get this by downloading oneAPI HPC Toolkit)

Before this, you need to run the setvars.sh script file(command: source /opt/intel/oneapi/setvars.sh) to set the environment variables
