2022-10-12 04:38:54 -0500	marked best answer	Unable to load ROS2 workspace into CLion I've been trying to get Ros2 to work with my copy of CLion using this guide on the Discussion Forums, but have been having no luck. I was wondering if there were more up-to-date instructions, since these were written in 2017. Or if I'm inadvertently messing something up. Probably the latter. Before we start, this is all on Ubuntu version 18.04 LTE, running on a Lenovo ThinkPad P52. So first off, the step for compilation seems to have a couple stderrors for me. I don't think they're the cause of my pain, but I'm a bit new to this, so who knows!

2019-06-10 13:56:28 -0500	marked best answer	Difference between launch and launch_ros Possibly a silly question, but here goes: What is the difference between ros2/launch and ros2/launch_ros? When should one be used over the other? They both have similar names, and (superficially) similar jobs, so I'm a little unclear which one I should be more heavily leaning on when writing ROS 2 launch files.

Any commits before that on the master branch will build just fine, whereas that one and all future ones will fail (always with the exact same error). The error continues to occur even if I delete my build and install folders, and try to have colcon reconstruct everything. HOWEVER I'm not sure that it's actually that commit's fault - my colleague is able to build rclcpp just fine. Which leads me to think that something got messed up in my environment. However, I don't really know where to start looking. Has anyone else run into this sort of an issue before? Was it an environment error? And if so, what should I do to make sure that this doesn't happen in future? I'm hoping that I can fix this without having to completely reinstall ROS2...
