Offer an easy-to-use environment to cross-compile Qt application on a Raspberry Pi. This repo contains all the scripts needed to prepare a sysroot, cross-compile Qt and deploy Qt libraries to your Raspberry.

Difference between init-qtrpi-minimal and init-qtrpi-full

  • init-qtrpi-minimal, the typical way: downloads ready-to-use Qt binaries for the Raspberry Pi and a minimal sysroot that we released on the download page
  • init-qtrpi-full, the custom way: compiles on your computer the Qt binaries for the Raspberry Pi to let you tweak the configuration, enhance the compilation by adding some missing Qt modules to QtRpi or add some specific third-party dependencies

Tutorial of

This tutorial will help you to:

  • Configure your host computer to be able to cross-compile Qt 5.7.0 applications for your Raspberry Pi 3
  • Deploy the pre-compiled Qt binaries on your Raspberry Pi
  • Cross-compile your application for a Raspberry Pi with the CLI or Qt Creator


  • A 64-bit Linux host computer
  • A Raspberry Pi 3 with Raspbian Jessie (Raspbian Stretch is currently not supported!)

In this example, you already have an SSH access to your Raspberry Pi 3 at with the user pi. The script will use sudo several times to install the packages on the board. You should add your SSH key in your Raspberry Pi. For example with ssh-copy-id:

ssh-copy-id pi@


First, install the dependencies:

sudo apt-get install curl g++ gdb-multiarch git realpath unzip zip

Open a terminal and follow the steps below:

git clone
cd qtrpi
export QTRPI_QT_VERSION='5.7.0'
export QTRPI_TARGET_DEVICE='linux-rpi3-g++'
export QTRPI_TARGET_HOST='pi@'
./ --prepare-rpi

Note: You can also export the environment variables in your .bashrc.

Usage in CLI

cd myproject

You can now copy and execute the generated binary file on your Raspberry Pi

Note: You can also add /opt/qtrpi/bin/ to your PATH in your .bashrc and call qmake-qtrpi without the full path.

Docker images

The images are tagged according to their target configuration.

Currently the following tags are available:

  • rpi3-qt5.6.2: Crosscompile Qt 5.6.2 for the Raspbarry Pi 3

Choose the image which fits your needs.

Building a Qt project

To build a Qt project, mount the directory containing the sources and the project file to the /sources path inside the container and run it. By default the image automatically executes qmake and make in the current working directory, which is set to /sources by default.


docker pull arose/qtrpi:rpi3-qt5.6.2
docker run -v /someqtprojectfolder/:/source arose/qtrpi:rpi3-qt5.6.2
