Release/1.13 build failing

[davidemorazzo]

I am trying to build the code in the release/1.13 branch and it is failing. The output error from colcon is

--- stderr: px4_msgs

I fixed this by removing the extra */ that was giving the error. There are a couple present that make the build fail

You are trying to build release/1.13 on ROS 2 Humble or Rolling, right? PX4 version 1.13 (and therefore px4_msgs and px4_ros_com) supports up to ROS 2 Foxy

[davidemorazzo]

Yes I am trying with ROS2 Humble. How can I use then RTPS on Humble?

[beniaminopozzan]

To use v1.13 on Humble you need to

• fix the */ that you spotted
• see if px4_ros_com works. From my experience it doesn't. But if you manage to have a working solution you are more than welcome to raise a PR!
