ROS2 distribution support: Humble

I just found out that the generated code contains reference to rclcpp::Duration which is removed in Humble. https://github.com/ros2/rclcpp/commit/6815022909086487f2b8dc14c0540b00d4cf61a0

It seems R2023a supports Foxy which is also about to go to EOL in a week or so.

Are you considering to switch to Humble? It will be good to get a rough estimate of the timeline for that as well.

Thanks

Hi Andinet,

Thanks for reaching out!

Yes, we are actively working on switching to Humble. For the latest updates to ROS Toolbox, see the latest prerelease in the coming month (link to prerelease download page).

By the way, I saw you mentioned the generated code contains reference to rclcpp::Duration. Just to make sure we have taken care of it, would you mind elaborate more about which functions are you generating code from? A reproducible function/script would be even better.

Thanks,

Josh

The code generated produces this deprecated then removed (as of Humble) call.

Thanks for the comment Jeremy.

When seeing "code generated", I was expecting to see a code generated from MATLAB or Simulink directly.
