Installing the Qt-libraries on Linux for both Linux and Windows platforms to
allow cross-compiling for Windows.
To use an installer a Qt account is needed and is created on the register page.
Open the installer page here
which immediately starts downloading the Linux installer.
For the Windows version click on the 'Windows' link to start its download.
Make the installer (qt-unified-linux-x64-?.?.?-online.run) executable using chmod +x *.run.
Run the installer ./qt-unified-linux-x64-?.?.?-online.run as a normal user and
use ~/lib/Qt as the requested Installation Folder.
When selecting components use Latest supported releases.
From section Qt6.6.x select the components:
2024-07: As of writing, the Windows installer
qt-unified-windows-x64-?.?.?-online.execannot be run yet
using Wine v9.0.
The only solution is to run it from a Windows VM and copy the result to a Linux filesystem.
To run the installer, sadly, the Windows OS system is needed.
Microsoft provides "Windows Development Environments" images for downloading.
For this a virtualizer is needed and VirtualBox and install
a development environment downloaded from here.
To install the latest Virtualbox follow this page.
Share a folder in Linux with the VirtualBox Machine as a drive (R:) to the home directory so the
Qt-installer can install it in R:\lib\QtWin.
When Qt updates its libraries and tools the Maintenance Tool can download them.
~/lib/Qt/MaintenanceTool
2024-07: The application
MaintenanceTool.exewill not run on Wine v9.0 at this moment so only a Windows VM is the only option.
To run the Windows Qt Maintenance Tool Wine is needed and to install the latest stable version follow
this page.
wine ~/lib/QtWin/MaintenanceTool.exe
QtWinTo make the ~/lib/QtWin directory usable for cross-compiling Windows targets some things need to be fixed.
For this a script is available
from this repository.
The script looks for the highest Linux Qt version directory ~/Qt/x.x.x and creates in the ~/QtWin/x.x.x
directory symlinks for Linux executables and overwrites some .cmake files which are referring to .exe files.
With each new Qt version the script could be subject to change since Linux and Windows are diverted a bit.
