mkl_intel_thread.dll missing error

[Yvan]

Hi, I am using Visual Studio 2019 with Intel oneAPI to try to run a Fortran code which calls some routines from IMSL Fortran Numerical Library 2019 (which I have installed with a license). I get the following error message:

The code execution cannot proceed because mkl_intel_thread.dll was not found. 

I tried to link my project to oneMKL automatically by selecting Project->Properties->Fortran->Librairies->Use Intel Math Kernel Library->Parallel and Sequential (I tried both).

I also tried to link my project to oneMKL manually by selecting Project->Properties->Fortran->General->Additional Include Directories-> C:\Program Files (x86)\Intel\oneAPI\mkl\latest\lib\intel64 together with Debug Information Format: Full and Optimization: Maximize Speed plus Higher Level Optimization.

I also tried to place the mkl_intel_thread.dll file directly in my project folder, and added it to the project via VS.

Neither attempt was successful. I am not sure what to do now, could someone help me please?

The MKL install does not add the folder with the MKL DLLs to the system PATH environment variable. You need to do that yourself. I assume you installed MKL from the oneAPI Base tooklkit.

It's the IMSL DLL that is referencing the MKL DLL - changing your project properties isn't going to accomplish anything. If your version of IMSL includes static libraries (you will need to reference a different INCLUDE file), you can try that.
