Thought I'd point out, this still wants cuda installed, it includes <CL/cl.hpp> from that lot.

E: Oh, that was an artifact of the version prior to tonight's push. I'll check it out.

@kode54 I thought I had pushed, turned out, I didn't. It's up now.

What update? Says the package hasn't been updated since last August.

E: Oh, luxcorerender has been updated.

Updated, please report back if the issues persist. Should now also work with OpenCL without CUDA.

@jamincollins

What version of luxcorerender do you use? I can't compile luxcorerender-git without cuda, so currently I can't test.

makepkg --cleanbuild fails with the following:

@lubosz luxcorerender-bin seems to be missing libluxrays, so it won't compile.

Did you compile luxcorerender-git with or without CUDA? Because for me it doesn't build without CUDA, so I can't really test.

I needed to install luxcorerender-git. cmake was not happy with luxcorerender and luxcorerender-bin.

I also needed to apply this:

Without the patch I was getting the following build error:

I get:

CMake Error at cmake/Dependencies.cmake:160 (MESSAGE):

I do have luxcorerender-bin installed.

Thanks, I pushed an update! The OpenCL error comes from luxcorerender, btw.
