Unable to build the packages

Hi, I'm trying to build the mgacician package, however the colcon build fails for dobot_msgs:
sudo colcon build
Starting >>> dobot_msgs
Starting >>> dobot_bringup
Starting >>> dobot_control_panel
Starting >>> dobot_description
Starting >>> dobot_driver
Starting >>> dobot_visualization_tools
Finished <<< dobot_description [1.62s]

Any idea's?
Hi @paddenstoeltje, you should create a clean workspace and build packages once again - this time without sudo.
Let me know, if it resolves the problem 😉
Hi thanks,
that worked. However I'm facing another problem now regarding CMAKE. It seems there is something wrong with my environment (although is is sourced):

I would try installing ament_package first.
sudo apt install ros-humble-ament-package
It is already installed. Still getting the error. No clue what is wrong.
dobot_msgs is just a package with custom msg, srv and action files. Check if you can build a package from Creating custom msg and srv files tutorial 😉
Reinstalling Ros2 resolved all the problems. Thanks anyway. It seems something was wrong with the environment.
