How to Set Up QtCreator for Cross-Compilation with CMake in 5 Minutes
Setting up QtCreator for cross-compilation with CMake took me 15-20 hours the first two or three times. The next half a dozen times took me 4 hours on average. The last two times took me 5 minutes – using the script presented in this post. I can cross-compile the Qt application for my embedded...

Showing Wayland Compositor Fullscreen in Portrait Orientation
Our Qt embedded system is displayed on a monitor mounted in portrait orientation. The system runs the Wayland compositor Weston as a window manager. HMI applications are shown rotated by 90 degrees – in landscape orientation. The system toolbar of Weston is visible. How can we configure Weston so that the applications are shown...
Determining the Architecture of Qt Embedded Systems: Getting Started
Which system-on-chip is best suited for your Qt embedded system? Should you build a custom Linux system with Yocto, use a container OS or a desktop Linux? Should you use Qt Commercial or Qt LGPLv3? How will the system be updated? What are the operating conditions of the system? How does the system communicate...
Cross-Compiling Qt Embedded Applications with QtCreator and CMake
We change the code of our Qt application in QtCreator and press the Run button to try the changes on an embedded device. QtCreator cross-compiles the application, deploys it to the device and runs it on the device. QtCreator performs these steps in a breeze, because we spent quite some time to define a...

CppDepend: A C++ Dependency Analyser
I evaluated the dependency analyser CppDepend on a real-life embedded application. My goal was to find all dependency cycles between classes in the application. I know that the application contains 50+ dependency cycles. CppDepend only found less than 10% of the cycles. Without rewriting the the source code, CppDepend would have found no cycles...
Webinar: Building Embedded Applications from QtCreator with Docker
In a webinar organised by The Qt Company on 8 July 2020, I showed how QtCreator builds an embedded application against a Qt SDK encapsulated in a Docker container. QtCreator doesn’t know which Yocto version was used for building the Qt SDK and which environment variables must be set for the SDK. QtCreator forwards...
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...
