The plugin for class ""Submaps" failed to load

[Elbert Huang]

All things look fine except Rviz when I run the 3D demon. The scan matched point clouds look fine, TF works well, submaps can be generated according to the printout.

However, the ""map" frame cannot be loaded properly. The error is as follows:

PluginlibFactory: The plugin for class "Submaps" failed to load. Error: Failed to load library /home/elbert/google_slam/install_isolated/lib//libcartographer_rviz.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code,  that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = /home/elbert/google_slam/install_isolated/lib//libcartographer_rviz.so: undefined symbol: _ZTVN17cartographer_rviz14DrawableSubmapE)

I noticed there were double slashes between lib and libcartographer_rviz.so. How could that happen? Does anyone get the same problem?

​First guess would be: you are building against one version of rvize (maybe indigo) and try running another (maybe kinetic). Otherwise it is hard to say what the problem could be.​

Hi, Holger:

  Thanks for your reply.

  It seems the version of rviz is probably the main reanson. Because I am using jade. I forgot to mention that. Docs said only indigo and kinetic were supported. 

  Is there any chance that I can use it in jade? Could you provide some advices?

  

  Be well

​We never tried with jade - it might require changes to the code base to support that. If you want to make these, I would totally review a pull request for this. Another alternative would be to run Cartographer inside a docker container that runs kinetic.​
