 +__Strip__
 +
 +Due to a problem with WSL1 the Qt5 core library file needs to be stripped.

 +===Demo===
 +
 +QT Creator is used to create project files and edit source code.
 +
 +<code>
 +qtcreator
 +</code>
 +
 +Follow this guide to create a simple project.
 +
 +<code>
 +Create Project...
 +  Application (Qt)
 +    Qt Console Application
 +      Name: QApp
 +      Build system: qmake
 +      Language: <none>
 +      Kit Selection: Desktop
 +</code>
 +
 +__main.cpp__
 +
 +This is clearly not a good example of a Qt application, but this code is just a demo.
 +<code>
 +#include <QCoreApplication>
 +#include <iostream>
 +
 +int
 +main(int argc, char **argv)
 +{
 +        QCoreApplication App(argc, argv);
 +
 +        std::cout << "Hello World!" << std::endl;
 +
 +        return 0;
 +}
 +</code>
 +
 +Qt5 make is used to create a working `Makefile' which is used to build the application.
 +
 +<code>
 +qmake
 +make
 +./QApp
 +Hello World!
 +</code>
 +
 +To build for Qt6, use qmake6 instead of qmake above.
