Hi, I’m actually running into a similar issue now trying to offload the compute to a desktop pc with a GPU. It seems that cloning git clone https://github.com/IntelRealSense/realsense-ros.git -b ros2-development with the development flag as instructed on the tutorial causes build errors if you are not using realsense 2.56, which isn’t the version that comes when installing with apt. I cloned with the ros2-master flag instead and was at least able to build the workspace.
