Qt 6 installed using Qt online installer

The homepage of the Qt Framework is https://www.qt.io . Go to this web page, create an online account. https://www.qt.io/download-open-source > "Download the Qt Online Installer" > Linux > "Qt Online Installer for Linux (64-bit)" > download a file named e.g. qt-unified-linux-x64-4.6.1-online.run into the directory e.g. "~/Downloads".

ls -la ~/Downloads # The downloaded file needs to have the "executable" chmod bit set.
chmod +x ~/Downloads/qt-unified-linux-x64-4.6.1-online.run
~/Downloads/qt-unified-linux-x64-4.6.1-online.run

Login using your Qt online account. Next > check the checkbox "I have read and agree to the terms and conditions of using OpenSource Qt", check the checkbox "I'm an individual and do not use Qt for any company" > Next > Next > enable "Help us improve" > Next > Custom installation, notice that the install directory is "~/Qt" > Next. Install the latest version of Qt6 and the latest version of the Qt Creator integrated development environment (IDE). There are some Qt6 components that are not used by KDE and can be left out when installing Qt6 e.g. WebAssembly, Android, Sources, Qt Quick 3D, Qt 3D, "Quick: 3D Physics", "Qt debug Information Files".

In the KDE Plasma app launcher you now have the application "Qt Maintenance Tool".

Set up kde-builder from scratch as usual.

Edit the file kdesrc-buildrc to look like:

global
...
    qt-install-dir  ~/Qt/6.6.0/gcc_64 # Where to install Qt6 if kdesrc-build supplies it
    libname lib
...
end global

Because we use libname lib, on the Linux OSes that use usr/lib/x86_64-linux-gnu/ instead of usr/lib/ some files are installed into ~/kde/usr/lib/x86_64-linux-gnu/, some files are installed into ~/kde/usr/lib/.

E.g. in prefix.sh, make sure to have both ~/kde/usr/lib/x86_64-linux-gnu/ and ~/kde/usr/lib/. E.g.:

export QT_PLUGIN_PATH=/home/username/kde/usr/lib/x86_64-linux-gnu/plugins:/home/username/kde/usr/lib/plugins:$QT_PLUGIN_PATH
export QML2_IMPORT_PATH=/home/username/kde/usr/lib/x86_64-linux-gnu/qml:/home/username/kde/usr/lib/qml:$QML2_IMPORT_PATH

export QT_QUICK_CONTROLS_STYLE_PATH=/home/username/kde/usr/lib/x86_64-linux-gnu/qml/QtQuick/Controls.2/:/home/username/kde/usr/lib/qml/QtQuick/Controls.2/:$QT_QUICK_CONTROLS_STYLE_PATH

How to write the entire verbose STDOUT and STDERR of kdesrc-build to a file

script -eq -c "kdesrc-build kconfig --no-src --no-include-dependencies --refresh-build --debug" ~/a.txt ;  sed -i $'s/\033\[[0-9]\+m//g' ~/a.txt

The sed part removes the terminal ANSI color escape codes.

script -eq -c "command" ~/a.txt is better than command |& tee ~/a.txt because kdesrc-build behaves differently if it is run in a user interactive terminal session (isatty).

If using tee, part of the output of kdesrc-build will not be written to file. E.g. the output of the cmake step, the final part of the make -j step, the final part of the make install step.
