2023-06-02 11:54:18 -0500 | commented answer | Colcon select Python version Thanks for the log info, that cleared things up quite a bit. It would have been nice to have that pasted from the start. |

2023-03-15 03:07:00 -0500 | marked best answer | Long compile time for ROS2 interface package I'm prompted to ask this because I just tried changing a single name in a single service of a *_msgs package and it took colcon over 2 minutes to recompile. I don't have a amazingly fast laptop and it is a relatively large package (~50 interfaces) but this seems like an awfully long time to have to wait for any source change at all. My understanding of the details of the interface generation process is fairly limited. Would anyone be able to shed some light on what's going on under the hood and where all this time is getting eaten up? |
