Hello everyone,

I have just completed my Chrono install, and am unable to run the sensor module demos due to what seems to be an NVRTC error.

Specifically, I am seeing the following error message:

Failed to create a ChOptixEngine, with error:
Error: "C:\Users\jkimball\Documents\Chrono\chrono\src\chrono_sensor\optix\ChOptixUtils.cpp at line 106
Catastrophic error: cannot open source file" - and then the camera.cu file.

If anyone has any experience with this error, I would really appreciate any insight.

Thanks!

Jeremy

Jeremy,

NVRTC does not always work on Windows machines. Make sure to unselect USE_CUDA_NVRTC during CMake configuration.
