@Catially I have not been actively working with ROS for some time, so I unfortunately can’t help

@Catially This is a pretty standard error for when GCC isn't aware of where the Ros2 core libraries are. This script will find your source code but it doesnt add the ros2 core libs to gcc builds. Through Jetbrains File | Settings | Build menu you can manually add libs or the easiest way is to source the ros core setup.py then launch clion from the same shell. Thus ros core libs will already be in the build env paths.
