• there are some syntactic changes: << < -> <<<. For some reason, I do not need to change all those in the code.

On Windows this is an annoying default in Visual Studio, what errors does clang give from this? I'm concerned that if any new kernel's are added by users of VS then it will brake the clang build.

Strangely it build fine for me on Ubuntu 20:04 - clang version 10.0.0-4ubuntu1.

Thx @cudawarped . I am ok fixing the << < as it goes with whatever new code comes in. This is the kind of error I get:

@vrabaud Could you add some notes how you build OpenCV + CUDA + Clang. Just to be sure that we are talking about the same thing.

@asmorkalov , for my purpose, I do not use nvcc but clang cuda instead. This is all internal to Google so I actually have no idea of the command lines unfortunately.

I am done adding missing implementations, PTAL
