How do I update the planner in example.launch?

[kevin-thankyou-lin]

Hi! I've set things up so that example.launch itself works fine. However, when I update e.g. example_planner_node.cc, and do the standard catkin build procedure the updates are not reflected when I do roslaunch on the example.launch file.

I've tried to catkin build at the 'root' directory of my workspace, but that fails when building mav_trajectory_generation_example.

~/new_ws$ catkin build

I did move the include folder into the devel folder of mav_trajectory_generation_example, but I get this error:

Would anyone know how to fix this?

Resolved - just delete the build and devel folders!
