Re: [eigen] mkl_intel_thread.dll

[Edward Lam <edward@xxxxxxxxxx>]

Hi Rui,

Your issue is related to MKL, not to Eigen so this isn't really the right place to ask. I'd consult the MKL documentation https://www.intel.com/content/www/us/en/develop/documentation/onemkl-windows-developer-guide/top/linking-your-application-with-onemkl/linking-quick-start.html to see if you're linking against MKL correctly.

In general on Windows, DLLs are searched from wherever the .exe file is placed, and then the PATH second. If placing the DLL in the same directory as your ..exe doesn't work, then it's likely mismatched. ie. the .lib you linked against doesn't match the .dll you placed there.

Cheers,

-Edward

Dear All,

I met a problem while using eigen. The development environment is vs2019 and language is c++.

The debugging process is normal， once directly use the executable program, there will be a

error warning missing mkl_intel_thread.dll.

It doesn't work even I had found an mkl_intel_thread.dll and put them under the file directory.

Needs your help, thanks!

Best regards,
Rui
