Ros2 Rolling release ?

[doisyg]

Hi Davide, Quick question, could you release plotjuggler for ros2 rolling ? And if not, what would be the recommended way of installing plotjuggler for using it with ros2 rolling (precisely the verison that needs the most debugging) ? From source + ros plugins ?

[doisyg]

Ok, so I managed to make it work with rolling by compiling from source the 3 repos: https://github.com/PlotJuggler/plotjuggler_msgs.git https://github.com/facontidavide/PlotJuggler.git https://github.com/PlotJuggler/plotjuggler-ros-plugins.git

plotjuggler_msgs needs to be ros2 and I had to fork plotjuggler-ros-plugins to make it compile with rolling/galactic. PR is here: https://github.com/PlotJuggler/plotjuggler-ros-plugins/pull/11

Then starts and seems to work fine with ros2 run plotjuggler plotjuggler

Thank you very much for the implementation. Worked for me also in Rolling. But in my case, the executable is under ros2 run plotjuggler PlotJuggler.

I will replay some rosbags to check it.

I am receiving the following error when running it. Therefore I am not capable to subscribe to ROS2 topics.

Which branches are you using?

PlotJuggler/ [foxy]
plotjuggler_msgs/ [ros2]
plotjuggler-ros-plugins/ [development]

Any recommendation about how to solve it? Thank you very much.

This is what I get at lunch, I only tested opening bags, there is proably an issue with the libDataStreamROS2:

I will try to fix it if Davide doesn't do it soon

[facontidavide]

I pushed the PR for the rolling distro of plotjuggler and plotjuggler_msgs.

I will wait for your green light before pushing the plotjuggler_ros_plugin

Great, I won't have time however to fix the libDataStreamROS2 plugin in plotjuggler_ros_plugin issue before next month, so if you have something already, go ahead
