Building from sources

Where to get the code

Navio2 is supported in the upstream ArduPilot repository.

How to build

ArduPilot binary for can be built using two ways:

1) Directly on your Raspberry Pi. Simpler, but slower. Build takes approximately 15 minutes.

2) Using a cross-compiler (on Linux PC or virtual machine). This is much faster, but requires one-time setup.

If you'd like to build on Raspberry Pi skip the next step.

Cross-compiler setup on Linux (optional)

Recommended compiler is the one that is provided by Raspberry Pi Foundation. Download and extract it somewhere, for example in /opt/:

sudo git clone --depth 1 https://github.com/raspberrypi/tools.git /opt/tools

If you're using 32-bit distro add the following to your PATH:

export PATH=/opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin:$PATH

For 64-bit distro add this to your PATH

export PATH=/opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin:$PATH

If you would like to add the compiler to the PATH permanently edit /etc/environment.

Building ArduPilot using Waf build system

These steps are the same both for compiling ArduPilot directly on Raspberry Pi and cross-compiling.

Download the ArduPilot code and update submodules:

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

Checkout to a specific tag in order not to fly off master. git tag to get a list of tags

For example, to build a copter binary:

git checkout ArduCopter-stable
or
git checkout ArduCopter-beta

Note that Waf should always be called from the ardupilot's root directory.

To keep access to Waf convenient, use the following alias from the root ardupilot directory:

alias waf="$PWD/modules/waf/waf-light"

Differently from the make-based build, with Waf there's a configure step to choose the board to be used:

waf configure --board=navio2

If future isn't installed then you should install it:

pip install future

Now you can build arducopter. For a copter use the following command:

waf copter

In the end of compilation binaries with the name like arducopter-quad will be placed in ardupilot/build/navio2/bin/ directory.

Tip

We suggest checking out ArduPilot docs for further details here. This is the most up-to-date reference.

If you're using cross-compiler transfer the binary to your Raspberry Pi:

rsync -avz ardupilot/build/navio2/bin/arducopter-quad pi@192.168.1.3:/home/pi/

Where 192.168.1.3 is an IP address of your Raspberry Pi with a Navio.

Instructions how to run ArduPilot on Raspberry Pi and to connect GCS to it are available in Installation and running section.
