Can't Build successfully on Windows due to errors relating to intrinsic emulation

[AdamJMiles]

Hi,

I followed the instructions on the readme and I'm running into errors during the 2-Build.bat process that I'm unable to figure out how to fix immediately. The errors are of the form:

C:\Program Files (x86)\Windows Kits\10\Include\10.0.26100.0\ucrt\wchar.h(277,30): error C3861: 'emu_mm256_loadu_si256': identifier not found [J:\OMM-Samples\_Build\External\NRD\NRD.vcxproj]

Are you able to assist?

Thanks,

I managed to get the sample compiling this morning by modifying the generated VS project files for NRD and NRIFramework to allow the compiler to natively use AVX. By default, these are set to "Not Set" which disallows use of AVX and therefore relies on "IntrinEmu.h" (part of MathLib) to provide the emulated AVX support. It's this path that doesn't seem to compile.

For me, I downgraded Windows SDK from 26100 to 22621 to make the compilation complete
