Install SITL on linux

http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html

Download ardupilot

If you don’t have a copy of the ardupilot git repository then open a terminal and run:

git clone git://github.com/ArduPilot/ardupilot.git
cd ardupilot
git submodule update --init --recursive

Install some required packages

If you are on a debian based system (such as Ubuntu or Mint) then run this:

sudo apt-get install python-matplotlib python-serial python-wxgtk2.8 python-wxtools python-lxml
sudo apt-get install python-scipy python-opencv ccache gawk git python-pip python-pexpect
sudo pip install future pymavlink MAVProxy

Add some directories to your search path

Add the following lines to the end of your ”.bashrc” in your home directory (notice the . on the start of that filename. Also, this is a hidden file, so if you’re using a file manager, make sure to turn on “show hidden files”). Note the order, it is important to have jsbsim/src before autotest in case you’re running a virtual machine.

export PATH=$PATH:$HOME/jsbsim/src
export PATH=$PATH:$HOME/ardupilot/Tools/autotest
export PATH=/usr/lib/ccache:$PATH

Then reload your PATH by using the “dot” command in a terminal

. ~/.bashrc
