The .pro file in depth

When you click on the Build button, what exactly is Qt Creator doing? How does Qt handle the compilation of the different platforms with a single .pro file? What does the Q_OBJECT macro imply, exactly? We will dig into each of these questions in the following sections. Our example case will be the SysInfo application we just completed and we will study what Qt is doing under the hood.

We can start this study by digging into the .pro file. It is the main entry point for compiling any Qt project. Basically, a .pro file is a qmake project file that describes the sources and headers used by the project. It is a platform-agnostic definition of a Makefile. First, we can cover the different qmake keywords used in the ch02-sysinfo application:

Guillaume Lazar

Guillaume Lazar is a software engineer living in France, near Paris. He has worked in different companies, from start-ups to multinationals, for the last 10 years. He took the opportunity to observe and learn many team organizations and technologies. In 2014, he founded his own software development company at the age of 27. The current hierarchical organization that applies to most companies seems obsolete to him. With his own company, he wants to try a different approach. Although he defines himself as a Qt framework lover, he likes to mix different technologies and platforms. He also spends time on game development, machine learning, and electronics, because "things" become "alive".
