Temporarily rolling back jazzy 4.2.0-1 update due to downstream issues.

[marcoag]

@ct2034 I will temporarily roll back your latest rosdistro pr for jazzy: ros/rosdistro#41859 due to a bunch downstream issues with the diagnostic_updater that are creating several jazzy regressions.

You can see failing "Downstream Projects" in:

https://build.ros2.org/view/Jbin_uN64/job/Jbin_uN64__diagnostic_updater__ubuntu_noble_amd64__binary/

It looks like some symbols might be missing from the binaries so it would be great if you can take a look at this. Feel free to send an update PR anytime.

Hi @marcoag. Could you please help me identify one failed run of the downstream jobs. I looked through almost all of them and could not identify one that failed due to diagnostic_updater

[marcoag]

Sorry, I didn't realized that after the rollback the downstream jobs would show up as successful and hard to find. Let me point some of them out:

https://build.ros2.org/view/Jbin_uN64/job/Jbin_uN64__swri_roscpp__ubuntu_noble_amd64__binary/24/consoleFull
https://build.ros2.org/view/Jbin_uN64/job/Jbin_uN64__swri_roscpp__ubuntu_noble_amd64__binary/24/consoleFull

The error show up like this:

/opt/ros/jazzy/include/diagnostic_updater/diagnostic_updater.hpp:378:(.text+0x6633): undefined reference to `diagnostic_updater::Updater::Updater(std::shared_ptr<rclcpp::node_interfaces::NodeBaseInterface>, std::shared_ptr<rclcpp::node_interfaces::NodeClockInterface>, std::shared_ptr<rclcpp::node_interfaces::NodeLoggingInterface>, std::shared_ptr<rclcpp::node_interfaces::NodeParametersInterface>, std::shared_ptr<rclcpp::node_interfaces::NodeTimersInterface>, std::shared_ptr<rclcpp::node_interfaces::NodeTopicsInterface>, double)'

Thanks for having a look btw.

I see. This is most likely caused by #331. Without looking too deep into it.

Unfortunately I am in the last hours before one week of vacations right now. If I don't find the time to do this over the weekend I can only look into it after July 30. Just FYI.

@Rayman could you please have a look at this if you have time. Most likely this just misses an include in the right place.

I've created a fix for the missing symbols: #388

The swri_roscpp package actually has another bug: swri-robotics/marti_common#742

To be honest, I'm a bit confused by the branches. It seems that ros2 is behind ros2-jazzy.

[ct2034]

@Rayman But, could you verify that #388 solved at least the above-mentioned linker problem?

[ct2034]

To be honest, I'm a bit confused by the branches. It seems that ros2 is behind ros2-jazzy.

And I fixed that. There were some features not properly backported. But in the future, please make all PRs against ros2.

If you have any more build failure, feel free to ping me
