I am trying to install the ROS plugin for CoppeliaSim and getting many errors. Here is the results of

I couldn't find any .so files that were compiled to put them into the CoppeliaSim root folder. CoppeliaSim is not loading sim_ros_interface as a plugin. I have updated the libPlugin folder in CoppeliaSim with the latest commit.

Can anyone help?

I have updated the libPlugin folder in CoppeliaSim with the latest commit.

It appears you didn't.

What does git -C $COPPELIASIM_ROOT_DIR/programming/libPlugin show --summary say?

Thank you for the response. Below is the output of the libPlugin summary:

    set console verbosity to debug

It looks like the most up to date version.

Well, setExtVersion / setBuildDate methods are from a previous commit (ffbb6e4c of 4 May) which obviously you must have.

There is something else going on on your machine. Try starting from scratch.

And by the way, you don't need to pass the cmake option -DLIBPLUGIN_DIR=... because it looks like you set $COPPELIASIM_ROOT_DIR (however this won't change the result).

I started from scratch in a fresh workspace. Getting new errors on build now:

The repositories used by plugins are typically:

• libPlugin
• common
• include
• simMath

make sure to update all of the above.

I updated all libraries and the build was successful. I copied the created folders to the Coppelia Sim root directory and I still am not able to use ROS with Coppelia Sim. Maybe my directory paths are not setup correctly? What is the correct way to install the ROS plugin? I have been following this tutorial: https://www.coppeliarobotics.com/helpFi ... torial.htm

Yep, that's the official tutorial. It usually works.

Although the option -DLIBPLUGIN_DIR=$COPPELIASIM_ROOT_DIR/programming/libPlugin is not necessary, but it won't hurt.

Stupid question: after the successful build, did you copy the plugin (libsimExtROSInterface.so) from /home/andrew/ROS/husky_ws/build/sim... to $COPPELIASIM_ROOT_DIR?

I could not find the generated .so file in my build folder. What is the exact path that it is supposed to be found at? I searched in the build folder but could not find anything.

I just realised that there is already a compiled .so file for the ROS interface in the linux distribution. I copied that to the root coppeliasim directory and it worked.

Thank you for all your help!
