Could you explain build example application

[mehmety888]

Hi,

I couldn't visualize ros messages in ROS2 rviz
When I try to echo a topic using ros2 topic echo /topic name, I got an error below

The passed message type is invalid.

I especially don't understand "build example application" step.

I am using C++11 and there isn't any support classes generated. I don't know how to use plugin. Is there any document how to do this ?

Please explain in detail,
Mehmet
