Compiling Fluidx3d for the first time in ubuntu 20.04 didn't report any errors, but when the computer was shut down and then started up again, the following error appeared when compiling Fluidx3d： image

Hi @wjsjtu123,

this is when the GPU doesn't show up as OpenCL device, due to driver issues. You can try sudo usermod -a -G render $(whoami)

What hardware are you using?

Kind regards, Moritz
