Error in finding atomic_load_8

[AndrewMoss]

Hi there,

I am following the https://visualgdb.com/tutorials/raspberry/opencv/build/ tutorial to cross compile to a raspberry pi. I am using Open CV 4.1.1. and Visual Studio 19.  I get to step 13 and I get these errors showing up. Can anyone let me know what to do to remedy the errors?

This looks like some sort of incompatibility between a specific version of the toolchain and a specific version of OpenCV.

Unfortunately, as both components are outside of our control, we are not able to cover this with our regular technical support, so our best advice would be to try asking on the OpenCV forums if anyone has encountered similar errors before.
