Do you need nav2_straightline_planner and nav2_sms_behavior packages? what do you try to use from this repo? I remember removing those two package from the WP in order to get GPS WP tutorial, but I don't remember on which OS/ros version have to do that. On iron all is working ok.

I was learning Nav2 from the tutorials for all the available features. Mainly for the time being, I am interested in the Navigating Using GPS Localization (https://navigation.ros.org/tutorials/docs/navigation2_with_gps.html) tutorial part implementation. I have no idea about the necessity of the nav2_straightline_planner and nav2_sms_behavior packages. I will try with ros2 iron. Thanks a lot.

Thanks. I tried with ros2 iron but it also didn't ran successfully.

you need to run rosdep install --from-paths src --ignore-src -r -y on ws folder before colcon build in order to get all dependencies. From your error xacro package is missing.

Thanks a lot for your help. At least I'm able to run this with the ros iron running following one by one. sudo rosdep init rosdep update rosdep install --from-paths src --ignore-src -r -y

only I was having errors in nav2_sms_behavior package building. deleting that package, others are running successfully.

No problem! This new feature help a lot with real robots in outdoor environment. I'm working on a real robot right now and except for the poor precision of gps, everything is working right. I can navigate with LLA waypoints avoiding obstacles with Lidar data. For the gps performance I will try with RTK.
