A Yocto Recipe for Qt Applications Built with CMake

How hard can it be to write a Yocto recipe for building a Qt application with CMake? Actually, it turns out to be pretty hard. I have seen my fair share of slow-and-dirty workarounds (nothing is ever quick with Yocto, not even the diry workarounds) how to force the Qt application into the Linux image and onto the device. Over the years, I turned my own slow-and-dirty workarounds into a hopefully quick-and-clean solution. Here it comes.

Creating A Custom Yocto Layer

After having built the reference Linux image from a SoM, SoC or terminal maker and having run it on the board, we must inevitably custom-tailor this image to our needs. We must create our own Yocto layer. We must remove all the unnecessary packages and make our core application start automatically on power-up. Here is a step-by-step guide how to turn the application layer for a Toradex Verdin iMX8M Plus board into our own custom layer. The guide should also work for other boards.

A Basic Continuous Integration Pipeline with GitHub Actions

In a previous post, I built a basic CI pipeline with CTest that uploaded its results to a CDash board. It worked fine except that we had to start the pipeline manually from the command line. In this post, we define a pipeline with GitHub Actions that runs the CI pipeline whenever a developer pushes a code change to a GitHub repository.
