Hello, could someone please give me some feedback on what's wrong? This is on Gentoo. Thanks a lot :-)

Can you try replacing cl2.hpp found in src/neural/openc with the original file from https://github.com/KhronosGroup/OpenCL-CLHPP/releases/download/v2.0.10/cl2.hpp

[SleepyMario]

That indeed did the trick. Should I close this issue now?

[dubslow]

That sounds like a bug in our file. Better leave this open until we have a fix for it. (I suspect it was something to do with the reformatting -- @frpays any thoughts?)

[borg323]

I am preparing a patch that fixes various build issues. In this case I think we should be using the unmodified version from Khronos Group.

[borg323]

fixed by https://github.com/LeelaChessZero/lc0/commit/3287af2fbdb10472ba1d696bf9a3653693fdb69f
