Are you sure you have CUDA 10.1 installed ? Does /Developer/NVIDIA/CUDA-10.1/lib/libnvrtc.10.1.dylib exist ?

Will have to check with my other mac.

Ah sorry, my nVidia Web driver told me I'm up to date so I thought I have everything ready but this is a developer's thing?
Can it be downloaded for free somewhere without an account?

Edit: Just downloading this and will get back later.

Edit II: Do I need Xcode too ??

I do not provide all the nvidia stuff .. you need to install 10.1 Cuda Toolkit full. Not just the driver.

You might also do

Code: Select all

install_name_tool -change @rpath/libnvrtc.10.1.dylib @rpath/libnvrtc.dylib /Users/YOURUSERNAME/Library/Application Support/Blender/2.82scripts/addons/BlendLuxCore/bin/pyluxcore.so 

This might enable other versions of cuda.

No the cuda installer should be enough.

Thanks for the explanation.

I'm not going to do that, way to much effort for something nice to have but not really needed given my powerful PC.
My main system is still 10.12.6, on the 10.13.6 partition there is only 11GB free space, not enough for those spacious development kits.

But thanks anyways

You could download the network installer
https://developer.nvidia.com/cuda-10.1- ... dmgnetwork

and run it with

Code: Select all

-s nvcc_10.1 cudart_10.1 nvrtc_10.1 nvrtc_dev_10.1

from the terminal.

this will do a minimal install.

In Windows version, we include the NVRTC DLL too

Oh i missed that thanks ! edited

and run it with

Code: Select all

-s nvcc_10.1 cudart_10.1 nvrtc_10.1 nvrtc_dev_10.1

from the terminal.

I have no idea what that means
Instead I installed the driver & toolkit but not the samples, and so could make the add-on work.
But when trying to render with the cuda setting there is a BVH kernel compilation error.

I updated the cuda driver (418.163) via system preferences and apparently still the nVidia web-driver is in use?
Do I have to run some app from the newly installed CUDA developer stuff first to activate it?
libnvrtc.10.1.dylib exists in the bin folder.

Can you run blender from terminal and post the output ?

This is the driver verision i run.
