crazyflie_tools does not contain a CMakeLists.txt file error while setup ROS2 and Gazebo

[Saswati-Project]

Hi All,
I need some help on ROS2 and Gazebo setup. I followed the blog Crazyflie’s Adventures with ROS 2 and Gazebo (https://www.bitcraze.io/2024/09/crazyflies-adventures-with-ros-2-and-gazebo/) for the setup. I followed all the command in step 1. Installation but got stuck on "colcon build --cmake-args -DBUILD_TESTING=ON" command. I attached a screenshot of the error command.

Can anyone please let me know how can I complete the colcon build?

Thank you.

Hello @Saswati-Project!

Sorry to hear that you're having issues with the Gazebo setup. Unfortunately, we do not actively maintain any simulations. As a result, users may need to perform additional setup and troubleshooting to get simulations working, mainly because of version-specific dependencies in ROS 2 and Gazebo.

Hope you manage to get it to work, and good luck with your project.

Thank you for your answer. If I understand correctly this error not related to any Creazyflie related software. Right?

[ArisMorgens]

Right. It seems that you're getting an error on the crazyflie_tools repository that is used in crazyflie_ros. These are not maintained by us.

I just want to share here how I fixed the problem.

cd /home//crazyflie_mapping_demo/ros2_ws/src/crazyswarm2
git submodule update --init --recursive

May be this will help others who have same issue.
