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...

Book Review: “A Philosophy of Software Design” by John Ousterhout
“Complexity is anything related to the structure of a software system that makes it hard to understand and modify the system.” John Ousterhout, The Philosophy of Software Design, Chapter 2 Complexity is also known as technical debt, which quickly grows into technical inflation. Strategic programmers understand that they must do everything to make progams...

Breaking Dependency Cycles in Qt Applications
A fairly common anti-pattern found in Qt applications is to derive a class MyApplication from QApplication and to have it hand out pointers to a dozen or more major components of the application. Similar to Qt’s qApp macro, these applications introduce a macro myApp pointing to the single MyApplication object. The global variable myApp...

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...
