There are no cuda libs in the package created by LuxCore Azure ..

Hi, testing latest Luxcore 2.4 on Linux and it work fine with but view port render compile forever.
I got following errors:

I have Cuda toolkit 10.2, GTX 760, driver 440.82

Viewport rendering on Linux is working fine here however I'm using CUDA 10.1 but 10.2 shouldn't be a problem. The error looks quite strange and like a driver internal error. Does Cycles with CUDA works on the same PC ?

@Dade, yes I compile Blender on this system and have to compile the Cuda kernel for my SM_30 card, too.
I will check on my Windows disk on the same system today.

Cheers, mib
EDIT: It work on Windows 10 with 441.87 but it show "Kernel OpenCL compilation need a few minutes, once." or so.
Back to Linux, will try to delete all kernels.
EDIT 2: It work now, delete all kernels and there was a lot of them.
Thanks for watching

@Dade, how does this work on Linux? Isn't it necessary to distribute the Nvidia nvrtc and nvrtc-builtins DLLs as for the other platforms?

I have to check but I assume the answer is yes (they are not included with the drivers).

Sorry for asking this silly question but where can you find CUDA support in luxcore 2.4 beta?

I am unable to know if via GPU it used openCL or CUDA?

It should be in BlendLuxCore addon preferences :?:
