Could you describe more what you are trying to do?
Which platform is this? Ubuntu? Which PX4 version?
Usually, you do not need to have PX4-Autopilot under your ROS workspace source.
Have you looked at this?
Or also our docs?
Yes, I understand that PX4-Autopilot is needless inside the ROS Workspace source. I am on ubuntu 20.04, ros noetic, current px4, earlier in my previous query I had imported an “mavros controller” repo of Jaeyoung-Lim but failed, currently following the above very documentation tutorial. When I am building the catkin workspace, 2 of the 7 packages are not building.
Subsequently, the roslaunch command is throwing error. I also have necessary things sourced.
hmm,
Have you installed Geographic lib?
wget https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh
sudo bash ./install_geographiclib_datasets.sh
