I have followed the instructions and wanted to try the Gazebo example with

ros2 launch ros2_control_demo_robot rrbot_system_position_only_gazebo.launch.py

Versions as of issue creation time:

  • Kubuntu 20.04, Foxy apt packages up to date
  • _control, _controllers, _control_demos on a fresh master in colcon_ws
  • gazebo 11.3.0

The output:

Could anyone help?

Can you launch your system with a verbose output of gazebo:
Turning this line to True: https://github.com/ros-controls/ros2_control_demos/blob/master/ros2_control_demo_robot/launch/rrbot_system_position_only_gazebo.launch.py#L36

do you also have gazebo_ros2_control packages built from source?

Hi, thanks for your inputs.

Here is some of the the output of a verbose gazebo run:

Then I additionally cloned gazebo_ros2_control to the colcon workspace (previously I used system install), but got an error building it:

protoc --version returns libprotoc 3.14.0

I managed to build gazebo_ros2_control by following step 1. in AcutronicRobotics/gym-gazebo2#13 (comment)

The gazebo segmentation fault still persists however, producing the same exact verbose output.

Hello, having the same issue.

Are you guys trying to compile things that clash on the protobuf compiler version? That's going to be a though nut to crack... I am not sure we can help you from ros2_control, essentially anything using gazebo will be broken. Are you trying to use gym + gazebo + ros2_control? That description seems to apply to ROS Crystal and Ubuntu 18, I'm not sure if it applies to Foxy and Ubuntu20 as well.

The compilation errors were solved by following the link referenced in my earlier reply #91 (comment)

The problem happens on runtime. It possibly still has to do with protobuf. Over the weekend I try to set up everything clean from scratch with a single version of protobuf on my system and report.
