Problem with Ros Interface

Post by Erfan »


I am trying to make a functionality between CoppeliaSim_EDU (version 4.1.0) and ROS noetic on Ubuntu 20.04.
I have followed all instruction posted on: ... torial.htm

However, after running the following command:

$ catkin_make --cmake-args -DCMAKE_BUILD_TYPE=Release

I have received an error as:

Hi, Erfan. How are you?

I have just successfully compiled sim_ros_interface in the Ubuntu 20.04/ROS Noetic/CoppeliaSim 4.1.0 combo.

First of all, the plugin requires the catkin build tool instead of catkin_make. You may install it with

Code: Select all

$ apt install python-catkin-tools
Then, remove build and devel folders from your catkin_ws, and from now on, compile the ROS workspace using

Code: Select all

$ catkin build
Second point, considering that you are using CoppeliaSim (version 4.1.0), download here the correct sim_ros_interface version. Extract it to your catkin_ws and rename this package folder to sim_ros_interface. Now go on and try compiling it again with your brand new catkin build tool!

PS. If you updated the <coppeliasim>/programming/libPlugin folder, maybe you will have revert this operation, e.g. by downloading and extracting again the CoppeliaSim 4.1.0.

Best regards, and good luck with your functionality! :)
