Build environment prerequisites

GCS Compiler Requirements

GCS requires a compiler with C++11 support. GCC 4.8, 4.9 and 5.3 are fully supported. Ubuntu release 14.04 or newer meet this requirement by default. See the Qt supported platforms list for further details.

Ubuntu/Mint/Debian derived distributions

First ensure your package manager is up to date:

sudo apt-get update

Next, get a host compiler and other build tools, along with your revision control environment:

sudo apt-get install build-essential gdb wget debhelper ccache git

If you are running a 64-bit version of Linux (if you run uname -m and the output says x86_64 you are in a 64-bit environment), you’ll also need to install 32-bit compatibility libraries.

sudo apt-get install gcc-multilib

Finally, install some additional libraries required to compile GCS

sudo apt-get install zlib1g-dev libusb-1.0-0-dev libudev-dev libgl1-mesa-dev libpulse-dev

Fedora (x64)

Install the required packages (tested on Fedora 26 Workstation):

    sudo dnf install libstdc++.i686 glibc-devel.i686 mesa-libGL-devel zlib-devel systemd-devel pulseaudio-libs-devel gcc gcc-c++ git ccache

For other Fedora-based distributions (e.g. CentOS) you may need to substitute yum for dnf.

Fetching source code and building

Cloning the repository

First, clone the dRonin repository. Change to an appropriate directory to check out the code. If you have your own fork, specify its URL on the git command line (otherwise you can use the parent fork per the below example).

git clone git://
cd dRonin

Automatic download and install of prerequisites

The dRonin build environment is capable of installing the rest of the tools that it needs.

GCS build tools

Next, run make qt_sdk_install, copy the path from the output in your terminal and paste it into the installer when prompted.

Don't install Qt to the default location!

When running the qt sdk install command, you’ll be told where to install qt, then the GUI installer will open. Here is what it will look like:

*  In the GUI, please use exactly this path as the installation path:
*        /some/path/src/dRonin/tools/Qt5.8.0

Be sure to copy the specified path into the installer when prompted for the install location!

GCS uses Google Breakpad for crash-reporting. Rather than compiling this every time you build GCS, it is built once during toolchain setup. Run make breakpad_install.

Flight firmware build tools

This is easy. Just type: make arm_sdk_install

Building for Raspberry Pi?

FlyingPi requires additional steps to cross-compile the dRonin flight stack for arm-linux. See setup guide for further information.

Building the software

You should be ready to go. Type make all to compile the entire project. Type make to see a list of possible make arguments.

Installing udev rules

You need to grant permission for normal users (i.e. not root) to access your flight-controller boards from the GCS. This is accomplished by installing specific udev rules for the various flight controller boards.

The udev rules are generated dynamically (from the file shared/usb_ids/usb_ids.json). To generate dRonin udev rules, copy them to your system and load them, run these commands:

make usb_id_udev
sudo cp build/shared/usb_ids/dronin.udev /etc/udev/rules.d/45-dronin-permissions.rules

and then:

sudo udevadm control --reload-rules

Device still not accessible?

You must disconnect and reconnect devices if they were already plugged in when you loaded the udev rules.

Running GCS

Launch the gcs with ./build/ground/gcs/bin/drgcs and connect to/flash your board.
