Thank you for the bug report! It seems like you're correct that the type should be a `str` field. * ROS msg files to OMG IDL maps char to char:...

It looks like this issue is comparing `rclcpp`'s `spin_all` to `rclpy`'s `spin_once`. I don't see documentation in [`rclcpp` for `spin_once`](https://github.com/ros2/rclcpp/blob/432bf21f0261bab209b37ccfe6da550f02751a22/rclcpp/include/rclcpp/executor.hpp#L317-L320), but I'd assume `spin_node_once` is similar just restricted to callbacks...

[ROS Rolling and Iron target Fortress](https://www.ros.org/reps/rep-2000.html#iron-irwini-may-2023-november-2024). It looks like [math 6 and sdformat 12 are the Fortress versions](https://gazebosim.org/docs/harmonic/release-features#fortress). I'd recommend watching for PRs to REP 2000 in https://github.com/ros-infrastructure/rep in November...

In the example it looks like "talkers" is a list of dictionaries. ROS 2 parameter lists/arrays can only be the types here: https://design.ros2.org/articles/ros_parameters.html#supported-datatypes I think workaround is to nest the...

There is a variable with all the CMake targets: `${_TARGETS}`, ex: `${std_msgs_TARGETS}`. There isn't a wrapper target at the moment. I don't remember what problems were had with it.

@mjcarroll would you be willing to try this on a windows machine? 🧇

IIRC correctly from the meeting this was discussed in, this is caused by packages not being separated into `-dev` variants. That is every ROS package is assumed to have both...
