Install Ubuntu 12.04 LTS
Go to the Ubuntu desktop image download page http://www.ubuntu.com/download/desktop and choose the 32 bit 12.04 LTS (long term support) version
Copy the image to an USB stick or burn a CD, follow the instructions on the Ubuntu download page. Boot your laptop with the created medium and install. That will take some time, it should be self explanatory. Check the Ubuntu web site for more information.
Install auxiliary software
Once your laptop boots with Ubuntu we can go on and get you compilers, libraries and everything that is needed to build Paparazzi. Start Firefox by clicking on its button on the left and go back this page on the laptop. Go to the Ubuntu "Dash Home" button in the upper left corner, click and type "terminal" to search for a terminal window. Drag&drop the terminal button to the quick launch bar.
Do the same with the gedit editor. Type 'gedit' into the start button and drag&drop the 'Text Editor' application icon to the quick launch bar. You might want to remove the LibreOffice quick launch buttons as you do not need that for flying. Right-click and choose "Unlock from launcher" to do that.
Next we need to add the installation sources for the Paparazzi software packages. Click on the terminal icon and execute
sudo add-apt-repository ppa:paparazzi-uav/ppa
The system will ask for your password as you run this with root rights. This will happen a few more times.
Then we update the systems package inventory and install the two main Paparazzi software packages. This will take some time.
sudo apt-get update sudo apt-get install paparazzi-dev paparazzi-arm-multilib
Retrieve and build Paparazzi source code
We use the source code managing software 'git' to get the Paparazzi source code. For simplicity we stay in the home folder and copy it to the 'paparazzi' subfolder.
git clone https://github.com/paparazzi/paparazzi.git paparazzi
We change into the paparazzi folder
and make sure to check out the version 'campaign2013' for SUMO measurements
git checkout -b campaign2013 origin/campaign2013
To allow access for USB flashing of your autopilot and modem use, some 'udev' rules need to be copied to the system
sudo cp conf/system/udev/rules/50-paparazzi.rules /etc/udev/rules.d/
and add yourself to the group 'dialout' for serial access (change USERNAME to your real username)
sudo addgroup USERNAME dialout
It is time to build the Paparazzi software
Create a shortcut on the desktop to easily start Paparazzi. Copy the launcher to the desktop
cp conf/system/launcher/Paparazzi.desktop ~/Desktop
make it executable
chmod a+x ~/Desktop/Paparazzi.desktop
and edit it to fit your username. Replace USERNAME with your actual user name in the 'Icon' and 'Exec' lines.
The icon should appear and you can start Paparazzi by clicking it. Voilà.
