Ideally I don't want to be running any that are built from source, as it seems more straightforward to run from the apt-get installed versions. Do the errors suggest I am running a built-from-source version? Perhaps my attempts to fix the nvidia-induced problem were not as successful as I thought.

I had deleted any rtabmap git folders from my catkin workspace and done catkin_make, the build was successful and there are no rtabmap folders present at all in src or in catkin_ws.

For the rtabmap version that was outside the workspace, I wanted to get rid of it completely and so ran sudo make uninstall inside the build directory (/home/ross/rtabmap/build). Should this be rebuilt if I do not aim to use the built-from-source version?

Is it possible to check which rtabmap versions I am running and which libraries it is looking for? I am relatively new to ROS and what with the nvidia problem I must apologise for being a little out of my depth!

EDIT: Righty ho, I have now deleted the build folder from home/ross/rtabmap/build, and re-run cmake.. , make and sudo make install. I deleted the catkin build folder and rebuilt it :) Sadly still the same error. How can I go about making a simlink for the libraries?

Is there a specific way to use ldd with rtabmap? If I type "ldd rtabmap" I just get ldd: ./rtabmap: not regular file


Thanks for the amazing support too!
