Error installing ros2_canopen - "cannot convert 'rclcpp::QoS' to 'const rmw_qos_profile_t&'"

[Lau86]

Hello, I am currently installing ROS 2 CANopen on my system, following the recommended procedure on the official GitHub repository. However, I am encountering an error when running the colcon build command. The specific error I get is as follows:

"error: cannot convert 'rclcpp::QoS' to 'const rmw_qos_profile_t&'"{aka 'const rmw_qos_profile_s&'}
30 |        init_service_name, rclcpp::QoS(10), client_cbg_);
      |                                                     ^~~~~~~~
      |                                                     |
      |                                                     rclcpp::QoS

package failed: canopen_core

I have checked that I am using the latest version of ROS 2 and that I have correctly installed all the dependencies required for ROS 2 CANopen. However, the error persists.

I've also checked the README.md file in the repository, but I can't find any specific information about this error.

Have any of you already encountered this error when installing ROS 2 CANopen? If so, could you help me to understand the underlying cause of this error and to find a solution?

I'm new to ROS so any help or suggestions would be greatly appreciated. Thank you in advance for your support!

Probably duplicate of #172.

yep, @Lau86 we haven't gotten to update the docs yet. If you use ros2 humble, please use the humble branch.
