Download Qt – ĭownload and untar Qt 5.12.5 or any other version you want to use. Next, we need to adjust our symbolic links in sysroot to be relative since this folder structure is in both our computer and Raspberry Pi. So, if we make changes in our computer sysroot, they can be easily transferred to our Raspberry Pi raspberrypi_ip is the network interface name or IP address of your Raspberry Pi. We can use rsync to synchronize our computer sysroot and the Raspberry Pi.

We are creating here a sysroot for Raspberry Pi cross compilation in our computer. Create and configure a sysroot – Ī sysroot is a directory structure that includes all the folders needed to run a particular system. Create working folder and set a toolchain – Ĭreate a working folder in your computer and download the toolchain. This folder ( /usr/local/qt5pi) will be used to deploy Qt from our computer to the Raspberry Pi. This step just involves creating a folder in our Raspberry Pi for the pi user.

QT SYNC TUTORIAL INSTALL

Sudo apt-get install libudev-dev libinput-dev libts-dev libxcb-xinerama0-dev libxcb-xinerama0 2.

QT SYNC TUTORIAL UPDATE

The next step is to update and install the required development packages. Use your favorite text editor for this, we are using nano in this example. We need to install some development libraries, so the first thing to do is to allow the system to install source packages, for this you only have to uncomment the deb-src line in the /etc/apt/sources.list file, which configures the system repositories.

Setup Qt Creator for Raspberry Pi cross compilation –.

Create working folder and set a toolchain –.

The label means this action is done in the Raspberry Pi, whereas means it has to be performed in you computer. The following list summarizes the main steps to cross-compile Qt 5.12 for Raspberry Pi, we will be describing each of them in this post. Select Interfacing Options, select ssh, choose yes and finish. We will need it later to comunicate Qt Creator with your Raspbery Pi. Make sure that you have activated the Secure Shell (SSH) protocol in Raspbian. Execute the following command in the Raspberry Pi command-line interface for updating the firmware. Also, check that you have the latest firmware, or install it and reboot the system. It is assumed that you have a SD card with Raspbian strech installed in your Raspberry Pi, otherwise download it and follow the installation guide. Also, have a look at the comments below for new findings. Stay tuned for updates about new versions. This is also mentioned below in the step 6. For Qt 5.12.2 to 5.12.5, the build configuration file must be set to linux-rasp-pi-g++ instead of linux-rasp-pi3-g++ in the -device argument. Note: this tutorial works for Qt 5.12 and 5.12.2 to 5.12.5 (it doesn’t for 5.12.1 due to some bugs). We would really appreciate your support to our work and website if this is fine for you.

Raspberry Pi Zero WH (WiFi and pre-soldered header).

Again, the tutorial steps should be quite similar in other configurations. The desktop Operating System (OS) is Linux (it works in most common Linux distributions: Ubuntu, openSUSE, Debian, Fedora, etc.) and the Raspberry Pi OS is Raspbian Buster, any version works (Raspbian Stretch is also supported). This tutorial considers Raspberry Pi 3 model B+ and Qt 5.12 branch, however these instructions should be similar for new Qt releases, as well as other Raspberry Pi board versions.

Updated for Qt 5.12.4 & 5.12.5, and Raspbian Busterįirst version for Qt 5.12, later updated for Qt 5.12.2 Qt creator is a powerful multi-platform Integrated Development Environment (IDE) to create and deploy your Qt apps and it is available for Linux, macOS and Windows.

This will allow you to design and build your Raspberry Pi apps in your computer thanks to Qt Creator and, execute and debug them directly in your Raspberry Pi.

QT SYNC TUTORIAL HOW TO

In this tutorial, you will learn how to cross-compile Qt 5.12 for Raspberry Pi in your computer and install it in your Raspberry. If you are not familiar with it, Qt is a rich framework with plenty of ready-to-use multi-platform components for diverse areas such as multimedia, network, connectivity, graphics, and much more. Qt 5.12 is a long-term support (LTS) release of the popular Qt framework.
