I have done all the installation steps on
However, when I run the colcon build command, I get the following error.

I would be very happy if you can help. thanks.

Hi @mertaydogan06. Moving this over to the Isaac forum for you.

You need the realsense2_camera from source or binary.

To binary install all required dependencies run this in the src folder of your workspace.
‘rosdep install -r --from-paths . --ignore-src --rosdistro $ROS_DISTRO -y’

In the latest version (Isaac ROS DP3), we removed the explicit dependencies on realsense2_camera in the ‘realsense_splitter’ package in the Isaac ROS Nvblox repo. You’ll need the realsense2_* packages when using a RealSense camera for tutorials as listed here, but otherwise, it should not be required to build all packages.
