Need a little help
Running Linux Mint 19.1 and had to roll some stuff back to the supported kernel and drivers, but in doing so I lost something and now when I try to render in Lux I get a clBuildProgram error and a never ending string of warnings in the terminal. Any idea of what I nuked? Some libopencl or something?
Re: Need a little help
Yes, it is an OpenCL related error, so check if your OpenCL installation is working, for instance by running clinfo or LuxMark. Check to have NVIDIA/AMD GPU driver installed.ajm wrote: ↑Tue Mar 12, 2019 9:36 pm Running Linux Mint 19.1 and had to roll some stuff back to the supported kernel and drivers, but in doing so I lost something and now when I try to render in Lux I get a clBuildProgram error and a never ending string of warnings in the terminal.

Re: Need a little help
This is the output but it looks like things are okay to me, unless there is an issue with the null device type.
Or should I have the mesa drivers installed?

Re: Need a little help
It looks right. Does LuxMark work ?
Nope.
Re: Need a little help
Can you post an example of the terminal output ?
Re: Need a little help
I would, but I used Timeshift and restored my system. Now I'll just have to watch for the dreadded random reboot, however everything works now. The output as I remember was a neverending stream of warnings that referred to a path that included cmake, I doubt that helps much. Seemed like it was during the kernel compiling phase.
Thanks for trying to help, Dade. Great advacements by the team, by the way.
