Qt 6 installed using the Qt online installer
A screen recording version is available https://www.youtube.com/watch?v=3BIbYN2vIZw
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 x64 > "Qt Online Installer for Linux (x64)" > download a file named e.g. qt-online-installer-linux-x64-4.8.1.run into the directory e.g. "~/Downloads".
ls -la ~/Downloads # The downloaded file needs to have the "executable" chmod bit set. chmod u+x ~/Downloads/qt-online-installer-linux-x64-4.8.1.run ~/Downloads/qt-online-installer-linux-x64-4.8.1.run
A graphical user interface (GUI) installer wizard starts. 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. Qt Design Studio, WebAssembly, Android, Sources, Qt Quick 3D, Qt 3D, Qt Quick 3D Physics, "Qt Debug Information Files". Next > enable "I have read and agree" > Next > Install.
In the KDE Plasma app launcher (start menu) you now have the application "Qt Maintenance Tool".
Set up kde-builder from scratch as usual.
Edit the file kde-builder.yaml to look like:
global: ... qt-install-dir: ~/Qt/6.8.1/gcc_64 # Directory to install Qt if kde-builder supplies it
Build Qt using kde-builder
Qt6
If you cannot build the KDE frameworks using kde-builder and the Qt provided by your Linux distribution is outdated, you might want to build the Qt framework using kde-builder.
In your configuration file use the qt-install-dir option (in the global section) with non-empty value, for example:
global qt-install-dir ~/kde/usr branch-group kf6-qt6 end global
It is recommended that if you build Qt6 using kde-builder, you also build qtwebengine. Edit the file ~/.local/state/sysadmin-repo-metadata/module-definitions/qt6.ksb. Follow the instructions found in the file: if you want qtwebengine, add it to use-modules after "qtwebchannel" and comment out the line "ignore-modules qtwebengine".
kde-builder qtbase --refresh-build --debug
Press Ctrl+C after the CMake configure summary for qtbase. Make sure that you have the needed dependencies. Should find libb2-dev, libproxy-dev, libmd4c-dev, libmd4c-html0-dev, libxcb-xinput-dev, libatspi2.0-dev, libsqlite3-dev, unixodbc-dev, libmysqlclient-dev, postgresql-client, libecpg-dev, libpq-dev. Optional dependencies libsctp-dev, libts-dev.
kde-builder qtwebengine
This will build the Qt6 modules from qtbase up to qtwebengine. qtwebengine will probably be built incorrectly because some needed dependencies are missing.
kde-builder qtwebengine --refresh-build --debug
Press Ctrl+C after the CMake configure summary for qtwebengine. Make sure that you have the needed dependencies. Should find node.js >= 14, libdbus-1-dev, libxcomposite-dev, libxshmfence-dev, libxdamage-dev, libharfbuzz-dev, libvpx-dev, libpci-dev, libevent-dev, libre2-dev, libsnappy-dev, libcups2-dev, libxkbfile-dev.
Then build Qt6:
kde-builder qt6-set
To compile Qt6 with Qt X11 Extras (which is a necessary library to compile KWindowSystem), you should enable XCB feature during compilation
kde-builder qt6-set --cmake-options="-DQT_FEATURE_xcb=ON"
OpenIndiana >= 2024.04
pkg update pkg install git pkg install build-essential cmake ninja qt6
