I am using http://ardupilot.org/dev/docs/using-rosgazebo-simulator-with-sitl.html instructions to install Gazebo SITL simulation.
The first instruction is: git clone https://github.com/alexbuyval/ardupilot. However I already I have SITL installed from http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html.
jh@jh-Lenovo-Ideapad-Z50-70:~$ git clone https://github.com/alexbuyval/ardupilot
fatal: destination path ‘ardupilot’ already exists and is not an empty directory.
Do I need to reinstall alex’s ardupilot over the previous ardupilot build ?
How is Alex’s ardupilot build https://github.com/alexbuyval/ardupilot.
different from the regular build http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html.
Also will these instructions http://ardupilot.org/dev/docs/using-rosgazebo-simulator-with-sitl.html work on ubuntu 16.04 ? The article recommends ubuntu 14.042, however documentation normally lags development. Is ubuntu 16.04 currently supported and where can I find the installation instructions for gazebo sitl on linux 16.04?
