Failed to build repos with msg packages

[fmrico]

Description

When a repo includes a package with custom messages and other packages that depends on it to build, I get a CMake error.

From here

CMake Error at /home/runner/work/book_ros2/book_ros2/ros_ws/install/br2_tracking_msgs/share/br2_tracking_msgs/cmake/ament_cmake_export_targets-extras.cmake:18 (message):

This bug is happening in CI in two of our repos:

• https://github.com/fmrico/book_ros2
• https://github.com/PlanSys2/ros2_planning_system

It is like the msg files are not correctly generated in CI, not in local

Expected Behavior

Successfully build

Actual Behavior

Error in building

To Reproduce

Check specified repos

System (please complete the following information)

• OS: Ubuntu Focal and Jammy
• ROS 2 Distro: Foxy and Humble

Additional context

I think I might also be getting the same error: https://github.com/ros2/ros2_tracing/runs/7892425175?check_suite_focus=true#step:5:745. This was fine before, but it started failing a few days or a week ago, so I think this is due to an upstream change (that doesn't happen when building locally). I haven't really had time to look into this.

I'm guessing you're relying on ROS 2 binaries, right? I think this doesn't happen if you make action-ros-ci build everything from source.

[clalancette]

We are currently in the middle of doing some revamps on the ROSIDL pipeline in Rolling. Everything currently works if you are building from source, but we've been holding off on doing a series of binary package releases since we have a bunch of more changes coming. That might explain what is going on here, a mismatch in the binary packages.

[christophebedard]

Thanks for the info @clalancette. My initial reaction was to use the pre-release APT repository, but that didn't seem to help.

[fmrico]

As @christophebedard said, building everything from sources does the trick, but it takes a lot of time (>45 minutes) build anything.

Please @clalancette, keep us informed on this issue as soon as we could use binaries again 🥺

[christophebedard]

Not being able to use the binary packages for a whole month(-ish) is a bit weird :/

I haven't tried reproducing locally; I wonder if this is in part due to the actions themselves.

Hi @christophebedard

I have just fixed it, using binaries, using osrf dockers instead of ros-tooling/setup-ros

I hope it helps

[christophebedard]

Thanks for the info @fmrico. I'll have to look into it and try to identify the difference(s) between setup-ros and that Docker image.

I have found the same problem in one action in RMF:

• Minimum example working https://github.com/orensbruli/rmf/actions/runs/3014305754/workflow
• Same example run in github action ubuntu-22.04 container https://github.com/orensbruli/rmf/runs/8248058649?check_suite_focus=true#step:2:9030

As you can see looking into the workflow files, I'm not sure it's related with ros-tooling actions (which are not used at all):

[christophebedard]

I haven't had time to look into it, but it looks like this is starting to work again for me: https://github.com/ros2/ros2_tracing/actions/runs/3095525905
