I installed ubuntu mate and then ros noetic on my raspberry pi 4. I built all of my packages with catkin_make, and it was successfully built. But when I run roscore and use rosrun, I couldn't find any packages I installed earlier, I even checked in dev and build file to see if those packages actually built and they were there. Then, I tried to create a simple package (hello_world) and it worked perfectly fine. Then, I installed those packages on my ubuntu laptop with the same ros noetic, and those worked fine too. I couldn't find any issue that makes those packages not able to run on raspberry pi 4.

Has anyone experienced this same issue before? What should i do to fix it?

Have you sourced the package? What happens when you run rospack list

I did source the package, and the rospack didn't show my package either

Have you checked that path is correct in your ~/.bashrc? If rospack is not finding it looks sourcing might have been done incorrectly. Sometimes if you try too many times your ~/.bashrc might have errors. Can you show it to help troubleshooting

I sourced the path incorrectly in my /.bashrc. Thank you for your help

In most cases when you don’t find a package when running rospack list it’s that it has not been sourced correctly. Pls check your ~/.bashrc.
