This project targets a new embedded platform, the Raspberry Pi. Qt officially supports the Raspberry Pi 2, but we got the project running without any trouble on a Raspberry Pi 3. If you do not have one of these devices, it might be nonetheless interesting to read this section to know how the cross-compilation works and how to configure your own kit in Qt Creator. The rest of the chapter will work on a desktop platform anyway.
Before diving into the Raspberry Pi's configuration, let's take a step back to understand our aim. Your computer is probably running on an x86 CPU architecture. This means that every program you run will be executed with the x86 instructions set of your CPU. In Qt Creator, this translates to your available kits. A kit must match your target platform. On startup, Qt Creator searches for available kits in your...
