In the *.sh script you have to set CARTOCONF to the cartographer configuration directory (https://github.com/Miro001/Ouster-cartographer/tree/master/ouster_slam), not to a single configuration file.

This is because the cartographer requires several configuration files to launch.
CARTOCONF='.../src/ouster_slam/' #own path

Hello, thank you again for your response.

I have actually left the sh file as is, which the CARTOCONF was set to CARTOCONF='.../src/ouster_slam_ws/' but I still get the error message below. Please check the last line, as it seems like the start up script has difficulty locating the /urdf/os_sensor.urdf file. Thank you.

Here is the directory screenshot from ~/ouster_slam_ws/ where I start the bash script.

changing the ~/ notation to /home/USER/ solved this issue. Thank you.
