Qt Embedded Systems – Part 2: Building a Qt SDK with Yocto

We want to develop the Internet radio application for the Raspberry Pi in the same way as for a PC. We change the source code in QtCreator and run the application. QtCreator cross-builds the application on the PC for the Raspberry Pi, deploys it with SSH to the Pi and runs it on the Pi. We need a Qt SDK for this to work. In addition to the target libraries from the Linux image, the Qt SDK contains the library headers, a cross-compiler, a cross-linker, a cross-debugger and more.

Using Docker Containers for Yocto Builds

We want to build a custom Linux image with Yocto for the Raspberry Pi 3 model B (BCM2837). The Linux image contains a very simple Internet radio application using Qt 5.11 and the eglfs graphics backend. Our colleagues shall be able to repeat the build easily – now, in three years and even in ten years.

I’ll explain why Docker is an excellent choice to build custom Linux images and give you a step-by-step guide how to do it. At the end of the post, you will be able to run a simple Internet radio on a custom Linux image on a Raspberry Pi 3.
