oneAPI 2025.0 (MKL): My code does not build any more

[rbunger]

Hi,

I have been able to build my code using oneAPI 2024.2 and earlier. Now with oneAPI 2025.0 it does not build any more. I do not have a minimal running example or similar... I just know that I was able to build with 2024.2 and now I get multiple errors. I call the oneAPI via the Eigen library.

I have tried with CXX=icpx and CXX=g++.

Thanks,

Rainer

Dear Rainer,

I have reproduced the issue using my sample code. It appeared that the problem probably is due to changes in the header file mkl_direct_call.h compared to earlier versions.

I have escalated this issue to our development team for further investigation and resolution.

Best regards,
