Introduction

To deploy Qt applications on a Raspberry Pi, you need to have cross-compiled your Qt dependencies. QtRpi is an open-source project that offers you:

  • All you need to cross-compile the Qt framework yourself (optional)
  • Precompiled Qt binaries for your Raspberry Pi
  • An easy-to-use environment to cross-compile your Qt Raspberry Pi application from your computer

Requirements

  • A 64-bit Linux host computer
  • A SSH reachable RaspberryPi

Installation

Cross-compile Qt applications for your Raspberry Pi 3 - 1. Install QtRpi from scratch (Youtube video)

  • init-qtrpi-minimal: Configure your host computer to be able to cross-compile Qt 5.7.0 applications for your Raspberry Pi 3. Downloads ready-to-use Qt binaries for the Raspberry Pi and a minimal sysroot
  • deploy-qtrpi: Deploy the compiled Qt binaries on your Raspberry Pi

git clone https://github.com/neuronalmotion/qtrpi.git cd qtrpi export QTRPI_QT_VERSION='5.7.0' export QTRPI_TARGET_DEVICE='linux-rpi3-g++' export QTRPI_TARGET_HOST='pi@192.168.1.12' ./init-qtrpi-minimal.sh ./deploy-qtrpi.sh --prepare-rpi

Usage in CLI
