segmentation fault when loading plugins

[scgroot]

Hi,

I try to use the latest version of PlotJuggler using the Ros plugins, but I struggle a bit.

When I use the version that comes trough apt-get I once again get questioned to update. Since I of course want the latest & greatest, I download the AppImage version from github! However, this does not have Ros2 (galactic in my case) support. When I try to use the default plugins (apt install ..) I get the following error message. Sometimes it works though, sometimes not..

What would be the recommended way of using the latest PlotJuggler with ros2 plugings? Are there maybe binaries available for the plugin that do work with the AppImage version?

Thanks in advance!

AppImage can not work ANY external plugins, including ROS ones.

You should install both plotjuggler and ROS plugins with APT
