it seems the ROS environment is not sourced (i.e. something like source /opt/ros/.../setup.bash) before running ./coppeliaSim.sh

which operating system?

libPlugin is a build tool, doesn't need installation

Find out which one is missing. Or might be a dep of one of those libraries, so you might want to run ldd recursively on the deps.

Yes: sim.groupShapes

Cheers

Shapes can be grouped:

Two or more simple shapes or compound shapes can however be grouped ([Menu bar --> Edit --> Grouping/Merging --> Group selected shapes]) or ungrouped ([Menu bar --> Edit --> Grouping/Merging --> Ungroup selected shapes]).

That means that the ROSInterface plugin cannot find some libraries.

This may happen also if you don't source the ROS environment (via the setup.bash/setup.zsh script).

Running ldd on the libsimExtROSInterface.so might tell you more.

You need to add all the dependent messages in meta/messages.txt

Defining a ROS message is something specific to ROS, not specific to the ROSInterface plugin itself. In a nutshell: create your own ROS package add your custom msgs add the custom msgs to your package's build system after this, you need to add your package as a dependency of sim_ros_interface , and ...

The location is the same as the location of the main application.
