Are your messages built?

Are they (or are they installed)? is autoware_msgs on your ROS_PACKAGE_PATH?

they seem to be installed. Don't they come by default when installing autoware?

What do you mean by "install autoware"? Installed from apt or from source or using docker? Please show the link you followed for the installation procedure.

Is the package on your ROS_PACKAGE_PATH? Can you roscd autoware_msgs?

Roscd autoware_msgs gives me no packages/stack of such existing. So i basically installed ros melodic following this:http://wiki.ros.org/melodic/Inst... Installed autoware 1.12 following this: https://github.com/Autoware-AI/autowa...

And now i would like publish the vehicle_cmd but also being being able to control it ..

you probably haven't sourced the built workspace. source <PATH_TO_WORKSPACE>/devel/setup.bash or source <PATH_TO_WORKSPACE>/install/setup.bash in every terminal
