CMake Cross-Compilation Based on Yocto SDK
We have succeeded in building embedded Linux with Yocto for a quad-core NXP i.MX6 (ARM Cortex-A9). Next, we want to cross-compile our own Qt application. As we use CMake for building our Qt application, we must create a CMake toolchain file. I am going to give a line-line by line explanation of the CMake toolchain file. I used Yocto Morty and CMake v3.5.1 (as it comes with Ubuntu 16.04 LTS).

30% Faster Startup Thanks to QtQuick Compiler
Update: Since Qt 5.12, the QtQuick compiler has been available under LGPLv3. Even if you don’t have a commercial Qt license, you will be able to enjoy a significantly faster startup of embedded QML applications.
It is not easy to find hard data about how much the QtQuick compiler can speed up the startup of real-life application. As I had some time on my hands this weekend, I measured the startup times of the HMI of a maize harvester running on a quad-core NXP/Freescale i.MX6 (Nit6Q_W_BCOM). Using the QtQuick compiler from Qt 5.7 brings the startup time from 2.72s down to 1.91s – a speedup of 30%!
