Paparazzi is very easily installed on any laptop or workstation running the Ubuntu Linux OS or virtually any Debian based Linux or Apple Macintosh running Mac OS X. There is also work being done to port Paparazzi to Windows.
The steps required to install the software needed to be able to let your UAS fly are:
- Prepare your operating system of choice for installation.
- Install any prerequisites for Paparazzi.
- Install all necessary Paparazzi tools.
- Download the source code from the source repository.
- Complete any final configuration (i.e. for hardware access).
- Compile the binaries from the sources.
OS Specific Instructions
This process varies depending on the operating system you are using. For detailed installation instructions, please see the following pages:
For more advanced installation information or developers, please see the following pages:
- Installing manually
- Installing everything from scratch
- In very rare occasions one needs to install the tools and third-party libraries used by Paparazzi all from scratch. Sometimes one just wants to be able to use all the latest and greatest compilers, or source code of everything to improve something. Then there is no other way than to install from scratch.
- Installing Paparazzi on Windows Note that this is a work in progress, and not finished yet. It would be fantastic if you are interested in running Paparazzi on this OS to help out with the porting. Being able to help is one of opensource software main features. If your skil- set is not so good in this area, but you still insist using Windows OS, then it is best to install a VirtualMachine from within Windows where you run the free Ubuntu OS of choice.
It is also possible to have your Debian/Ubuntu running in a virtual machine, for instance with VirtualBox. This requires minimal changes to your computer setup, as you can run the VM from all common platforms (Windows, OS X, Linux). The virtual machine image can easily be transferred between different laptops, giving greater flexibility. Unfortunately, the Open-Source Edition of VirtualBox doesn't include the necessary USB support, so you'll need to get the regular version from the website.
If you are new and this is your first time installing it is suggested you keep it simple. Use the standard Linux or OS X install. Select a system you can dedicate to the Linux installation. No VMs or dual boot configurations. The idea is do a very simple generic installation that is certain to have no issues. This reassures you that the installation process works and you can see and use a working Paparazzi install for some time before you try a more complicated install. The install is well documented and certain to succeed if followed exactly. Most issues arise when someone unfamiliar with Paparazzi or their OS tries a non-standard install that requires special steps that are not documented. Generally, commands can be copied and pasted for easy, step-by-step installation.
Downloading the Source Code
The complete source code should be downloaded from the paparazzi software repository on Github. Make sure you have installed the paparazzi-dev package as described above. Whithout these you will not be able to compile the sourcecode.
See the project page at Github for more details. From the directory of your choice type:
git clone git://github.com/paparazzi/paparazzi.git
or if you are behind a firewall with an http proxy available:
This will download all of the paparazzi sourcecode need for an autopilot to work into the directory paparazzi/
If this whole "Git" thing is new to you an you are curious, more options and information can be found on the git page.
Launching the Software
The first step is to compile. From the paparazzi directory (cd ~/paparazzi), run
You will have to run this command after each update of the source (git pull command). Launch the software from the paparazzi directory with
If (and only if) you want to directly launch some Paparazzi agents (the Tools of the Paparazzi Center), without using the Paparazzi Center, you must have the Paparazzi source and home environment variables set correctly in your shell. These variables can be automatically set in your shell by adding the following lines to your .bashrc file:
export PAPARAZZI_HOME=your paparazzi software directory export PAPARAZZI_SRC=your paparazzi software directory
If you wish to manually set the env variables (i.e. when compiling a backup copy of your code in a different folder) execute the following command from the folder you wish to set as your active paparazzi folder:
export PAPARAZZI_HOME=`pwd`;export PAPARAZZI_SRC=`pwd`
Verify that your variables are set correctly with the following command:
env | grep PAPARAZZI
which should return the following:
PAPARAZZI_HOME=your paparazzi software directory PAPARAZZI_SRC=your paparazzi software directory
Paparazzi is a very rapidly evolving project and as such you might want to update your software regularly.
Any new files you created will not be lost/overwritten when updating (like your own airframe file). Nevertheless, as with all things, backups are advised. If you modified source code, the best way is of course to use the version control system Git to commit your changes. Otherwise at least use the brute force method and save everything in another directory.
Update your software with care and caution, and always test the functionality on the ground and in the air as some updates will affect tuning parameters. You might need to update your airframe file as well. The compiler will usually complain if there is a problem, at which point you can look at the Airframe Configuration wiki page again, look on the mailing list or some of the most recent airframe files on git to find the proper syntax. See the Compiling page for more help if needed.
That said, keeping your software up to date is fairly easy with Git.
To download and automatically merge any updated source files, run the following command from your Paparazzi directory
Please see the Git wiki page for more details.
After any git update or source code modification the code can be recompiled from your paparazzi software directory with the following command:
The make command will only recompile portions of the software where changed have been detected. If it does not behave as expected you can deleted all compiled files and recompile from scratch with the following commands:
make clean make
See the Compiling page for more info.
Using the Live CD
There is a LiveCD available, but it dates back to 2008. It is still an easy way to get a first glimpse on Paparazzi.
