====Qt====

How to get up and running using Qt on Linux.

===Environment===

Kali Linux

===Operating System===

Windows 10 WSL1

===Update===

<code>
sudo -s
apt update
apt full-upgrade
apt autoremove
</code>

===Install===

==Qt5==

__Creator__
<code>
apt install qtcreator
</code>

__Base__
<code>
apt install qtbase5-dev
</code>

__Serial__
<code>
apt install qt5serialport-examples libqt5serialport5-dev
</code>

__Strip__

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

<code>
strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
</code>

==Qt6==

__Base__
<code>
apt install qt6-base-dev
</code>

__Strip__
<code>
strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt6Core.so.6
</code>

===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.
