Rviz is unable to find the correct urdfdom version
sspatank opened this issue · 4 comments
When I try to run rviz through my commandline, it starts up without any of the plugins and throws the following error.
[ERROR] [1670253530.576930800]: PluginlibFactory: The plugin for class 'rviz/Orbit' failed to load.
Error: Failed to load library /home/[my_username]/anaconda3/envs/ros_env/lib/librviz_default_plugin.so.
Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML.
Error string: Could not load library (Poco exception = liburdfdom_world.so.1.0: cannot open shared object file: No such file or directory)
It looks like the plugin library lib/librviz_default_plugin.so is unable to find liburdfdom_world.so.1.0.
When I ran ldd lib/librviz_default_plugin.so | grep 'not found' I got the following output:
liburdfdom_world.so.1.0 => not found
liburdfdom_model.so.1.0 => not found
When I searched for those libraries using ls lib | grep urdfdom I got a different version installed on my computer:
liburdfdom_model.so
liburdfdom_model.so.3.0
liburdfdom_model_state.so
liburdfdom_model_state.so.3.0
liburdfdom_sensor.so
liburdfdom_sensor.so.3.0
liburdfdom_world.so
liburdfdom_world.so.3.0
urdfdom
urdfdom_headers
Looking at the version installed with conda using conda list | grep urdfdom I get the following output:
urdfdom 3.1.0 h068d047_1 conda-forge
urdfdom_headers 1.1.0 h924138e_0 conda-forge
It looks like the version installed is higher than the version librviz_default_plugin is looking for. Why is it looking for that version? Can I make it point to the higher version I have available?
Your environment
- OS Version: Ubuntu 20.04.5 running on Windows WSL2
- ROS Distro: Noetic running on Conda|Robostack
- RViz, Qt, OGRE, OpenGl version as printed by rviz:
rviz version 1.14.5
compiled against Qt version 5.12.9
compiled against OGRE version 1.10.12 (Xalafu)
Forcing OpenGl version 0.
- If source build, which git commit? N/A
- System locale, i.e. the output of
echo "$LANG $LC_NUMERIC": en - Before reporting a rendering issue, try running RViz with
LANG=C rviz!: Tried that. Did not help
rviz is looking for the urdfdom 1.1 version it was compiled for. If you are running a conda environment, you should install and run rviz from that environment too. You can't mix the default Debian environment with your conda environment.
If you have rviz installed in your conda env and you get this error, you should file a bug report to RoboStack.
Note, there is no need to run a conda env for ROS Noetic in WSL2. You can simply follow the default ROS install instructions.
Thank you. I have posted my issue there. I needed to use conda because I need a different python version for another project on WSL2. There has been no mixing of Debian and conda environments and so I think it's probably a robostack conda issue. I'll link to that issue once it gets resolved for any future travelers.
As for this ticket, I don't see that this rviz links to any particular urdfdom library in the source code or cmake files, so how does the linker know to look for urdfdom version 1 and not version 3?
This comment on my issue raised in Robostack/ros-noetic fixes this issue.
The fix is to install urdfdom version 2
I don't see that this rviz links to any particular urdfdom library in the source code or cmake files, so how does the linker know to look for urdfdom version 1 and not version 3?
rviz was compiled and linked against version 1 originally - the version available at compile time.
The corresponding library versions were stored by the linker.
