Gazebo-Sim Tutorial Build Error

Describe the bug
Unable to build the ROS 2 package for integrating the ros2_control controller package with docker
To Reproduce
Steps to reproduce the behavior:
- Go to 'tutorial'
- Run
cd Dockerfile
sudo docker build -t gz_ros2_control . - See error
Screenshots
Environment (please complete the following information):
- OS: Ubuntu 22.04
- Version Humble
Are you speaking about the Dockerfile of this repository, or gz_ros2_control?
@BobbieZain Can you check #284? but how did you pass the colcon build step with the wrong branch?
@BobbieZain Can you check #284? but how did you pass the colcon build step with the wrong branch?
I'll uninstall and build the control package again
the problem persists, FYI I'm using ROS 2 Humble and this is the humble branch
The linked PR has not been merged yet, please checkout the correct branch before you run the docker command.
There is another issue, #286
docker run -it --rm --name gz_ros2_control_demo --net host gz_ros2_control ros2 launch ign_ros2_control_demos cart_example_position.launch.py gui:=false
works perfectly on my machine.
Turns out the previous issue comes from not sourcing the setup.bash. The docker build runs normally now, but gives the error message about qt.qpa and rcl
@christophfroehlich This code
sudo docker run -it --rm --name gz_ros2_control_demo --net host gz_ros2_control ros2 launch ign_ros2_control_demos cart_example_position.launch.py gui:=false
Doesn't launch gazebo as expected.
Also could you please suggest some solutions regarding this error of
Could not contact service /controller_manager/load_controller which appears when I try to run the demos after colcon building
gz_ros2_control_demos
The "could not contact controller manager" error of the spawners just means that gz_ros2_control was not started properly. You have to read the earlier error messages in the log.
On which system are you trying to run the docker?
The qt errors mean that gui:=false was not used and it tries to launch the gui.
sudo apt install ros-humble-ign-ros2-control
fixed the problem of gz_ros2_control, which I thought was installed along with the ros2 control package
And this is the docker system info
I just tried it again. It built successfully but I was not able to run gazebo without gui with the given examples, see #302
However, with the change in the gz_args to use -s it launches as expected for me
# ros2 launch ign_ros2_control_demos cart_example_position.launch.py

I'll close this issue now because the "build error" is fixed, and the issue with the gui parameter is reported in #302
