2023-07-27 15:22:19 -0500 | marked best answer | Colcon Tutorial on Dashing does not build Ubuntu 18.04 running Dashing on hash bafddbdb of master The example from the Colcon Tutorial does not build. https://index.ros.org/doc/ros2/Tutori... I kept getting errors like this from colcon : Could not find a package configuration file provided by "example_interfaces" with any of the following names: I grepped through the commit logs of this repo and 64128033 seemed like the cause - so I cloned https://github.com/ros2/example_inter... into my src directory such that my filesystem was like this ---- src -------- examples -------- example_interfaces and Cmake stopped complaining about an unknown dependency. After that I got a build error on master, went to the dashing branch and got farther, but I kept getting more colcon errors, and after cloning the following three repos into my src directory colcon built for me https://github.com/ros2/rclcpp https://github.com/ros2/rcl_interfaces https://github.com/ros2/test_interfac... my final directory structure looked like this: . ---- src -------- examples -------- example_interfaces -------- rcl_interfaces -------- test_interface_files Did I miss a step in my install or is that tutorial lacking these steps? Thanks |

In the feature request I see that there was intent to add support for these to the Are there any full examples of creating an xml launch file and then using the launch cli tool to run it? The design document and the test here show me the syntax, but I'm still unsuccessful. |

Today, I wanted to try out the teb local planner. Building and loading the plugin were a breeze, but for some reason, whenever I set a goal, I get this transform error: Then my robot enters a recovery state, until it hits this error again. If I switch back to using DWB, the error is gone!. I'm using cyclonedds as my rmw implementation on ros2 foxy |
