Issue in building the package car_gazebo_plugin.

[Rak-r]

I have followed the instructions and at the first time it worked but I am trying to inherit the car_gazebo_plugin to my robot for ackermann drive and I have removed the shock from all 4 wheels and commented out these from the plugin hpp and cpp files and trying to build the package but it is giving error:
colcon build --symlink-install

I also want to ask that the in the urdf you have used libgazebo_ros_control.so which is not available for ros2. It is gazebo-ros2_control plugin. So, how it is working? I tried to add the same and it is giving me the error: Failed to load plugin, no such file or directory. How I can use it?

I get the same warning, and haven't dug in to how to fix it, but so far it seems benign.

What about the libgazebo_ros_control.so part?

[berickson]

It's probably unused and silently failing to load. I can try removing and see what effect that has.

oh! ok. I tried to add it and it gives error. I will probably do the same thing. Thanks for the response and it is great that you made ackermann support plugin. If you need any help in updations I can definately contribute.
