ros-humble-ros-gz is still not sync in the debian packages I made the release 2 days ago. It should happen in the following weeks, for now you can compile the code using the humble branch.

Thank you for the rapid response.

Discrioption

I changed the branch to humble and followed the same procedure, but I encountered a problem where the colcon build would freeze.

Enviroment

Source, branch is latest humble

Steps to reproduce

  1. I followed the step Readme by humble branch.
  2. I executed build with colcon build into my workspace.

    Result

    It freezes during colcon build.

Package suspected to be the cause

  1. I executed build with colcon build --packages-select ros_gz_bridge into my workspace.

Result

Similarly, It freezes during colcon build --packages-select ros_gz_bridge.

Thank you for cooporation!

Discription

The communication connection between ROS 2 and Ignition Gazebo is success via ros_gz_bridge.

What is problem

The problem was with my computer specs.

approach

When I ran colcon build --parallel-workers=1 --executor sequential on a high spec computer, the build went through without freezing.

Input into my commandline

ros2 run ros_gz_bridge parameter_bridge /world/simu/wrench@ros_gz_interfaces/msg/EntityWrench@gz.msgs.EntityWrench
