issue with MKL with visual studio

[YusufThaer]

Dear All,

until today, I had visual studio 2019 installed with Intel Parallel studio and all was fine. I decided to install the new Intel onAPI. I uninstalled Intel Parallel Studio at first, then downloaded the one API base and HPC toolkit. I installed the base first then installed the HPC. I am doing that for using it for FORTRAN

I tried running my old projects that use use MKL as parallel or even sequential. I cant run any project that use MKL, I am sure the libraries are there in the directly and the visual studio rebuild the project without error but when I try to run the project, it tells me

" The code execution cannot proceed because mkl_intel_thread.1.dll was not found. reinstalling the program may fix this problem " . I uninstalled the hpc kit then uninstall the base one api then reinstall them again but it didnt work.

Hi Yusuf,

As this is issue is related to MKL, we are moving this thread to the MKL forum(Intel® oneAPI Math Kernel Library & Intel® Math Kernel Library - Intel Community) for better support.

Hi,

The issue is reproducible in my environment as well. However, there is a workaround given in this thread below.

Could you please try it out and let us know if you face any issues?

Thanks,

thank you very much

I tried it and it worked.

When I opened oneAPI command and write DEVENV, the visual studio starts and things work like charm.

but I couldnt add the path as I dont know how to add it

[JohnNichols]

1. Download a program called file seek. 

2. Do a search on the c: drive for mkl*.dll

3. This will tell you where the missing dll's are located

4. Copy the folder location as text from Windows explorer

5. Open the environment variables -- google it 

6. Add the location to the path command 

7. It should work until the problem is fixed in an update.

I found the place where the missing dll exists. I copied the path from the explorer and added it in the environment in debugger but it didnt work.

Hi Yusuf,

Follow these steps to include the missing DLL path:

• Open the project property pages (Alt + Enter)
• Change the Configuration to Debug (On the top left corner)
• On the left window, under the Configuration properties tab, click on Debugging.
• Under the Action tab, click on the Environment field and add the following:

PATH=C:\Program Files (x86)\Intel\oneAPI\mkl\latest\redist\intel64;%PATH%

Save the changes and run your executable. Let us know if you face any issues.

Thanks,

Rahul

No longer working. I just installed the latest version yesterday 6/19/2023 and repaired it today. 

My code uses MKL, it can compile and build as both Debug x64 and Debus x86, but when executed I get "mkl_sequential.2.dll was not found."

This code was working back in 2018. 

What can I do?

Hi,

Thanks for accepting the solution. The missing DLL issue will be fixed in the next oneAPI update.

Hi,

The missing DLL issue has been fixed in the latest release of the oneAPI base toolkit 2021.2. So, I will go ahead and close this thread from my end. Intel will no longer monitor this thread. Further interactions on this thread will be considered community only.

Thanks,

Rahul
