Actually I have a wider problem, but I'll start a separate topic on the many errors encountered on a default Ubuntu install using the directions on your Configuring Your Environment page. Keep in mind that I'm compiling on Ubuntu, not on the EB. And I meant 1.5.7 of MAVProxy which is installed by default with sudo pip install MAVProxy. I confused Mavros with MAVProxy in this topic, sorry about that. However, in your Configuring Your Environment page, you point the user to "git clone https://github.com/erlerobot/mavros.git", is this no longer correct? It's different than the link you just provided.
Anyway, where do I run the git checkout command that you mention at https://github.com/erlerobot/ros_erle_takeoff_land ? If you could answer the git checkout question, it would be appreciated. Should the build be looking for CommandBool.h, and where is this file typically located on a default Ubuntu install following your directions. I don't see it anywhere, thanks.
