| == kdesrc-build Qt5 ==
| | kde-builder has replaced the previous KDE build framework named kdesrc-build. |
| | |
| kdesrc-build by default uses Qt6. Your kdesrc-build installation is configured for Qt6 if in the configuration file <code>kdesrc-buildrc</code> you have <code>branch-group kf6-qt6</code>.
| |
| | |
| You can convert your kdesrc-build installation from Qt6 to Qt5 by editing the existing kdesrc-buildrc file to replace all occurrences of the letter "6" with the letter "5".
| |
| | |
| Set up kdesrc-build following the "Set up kdesrc-build" procedure. The resulting kdesrc-build installation will be of type kf6-qt6. In kdesrc-buildrc in the "global" section you will have "branch-group kf6-qt6".
| |
| | |
| Edit the file <code>~/.config/kdesrc-buildrc</code>
| |
| * Replace all "6" with "5".

| ==== Building without kdesrc-build ==== | | == Other operating systems == |
|
| |
|
| You can build a single repository using the [https://community.kde.org/Neon/Containers KDE Neon Unstable docker image]. We will be using the <code>plasma:unstable</code> image, which comes with the latest KDE software and libraries, and we will be using the minimal version, which requires you to install development libraries before compiling your projects.
| | === Kubuntu >= 24.10 === |
|
| |
|
| After installing distrobox and podman, run the following to create a new distrobox container:
| | The default configuration of kde-builder requires Qt version 6.7. Kubuntu 24.10 has Qt version 6.6. It is recommended that you use a [[Get_Involved/development#Operating_system|Linux OS that is better supported by kde-builder]]. |
|
| |
|
| {{Input|
| | If you are a more seasoned developer you might be able to use Kubuntu for kde-builder by [https://develop.kde.org/docs/getting-started/building/kde-builder-setup/#qt6-online installing Qt6 using the Qt online installer] or by [https://develop.kde.org/docs/getting-started/building/kde-builder-setup/#qt6-build building Qt6 using kde-builder]. |
| podman pull invent-registry.kde.org/neon/docker-images/plasma:unstable
| |
| distrobox create --image invent-registry.kde.org/neon/docker-images/plasma:unstable
| |
| }}
| |
|
| |
|
| This will create a distrobox container named '''plasma-unstable'''.
| | === Alpine Linux === |
|
| |
|
| {{Note|The plasma:unstable image size is 5.6 GB.}}
| | <pre> |
| | | apk add git perl doas-sudo-shim |
| Lastly, enter the generated container:
| | </pre> |
| | |
| {{Input|
| |
| distrobox enter plasma-unstable
| |
| }}
| |
| | |
| You can then just clone the desired repository in your home folder and build it while being inside the container. If any development libraries are missing, you can just install them the same way you would install on Debian/Ubuntu/KDE Neon:
| |
| | |
| {{Input|
| |
| sudo apt install packagename-dev
| |
| }}
| |
| | |
| You can also use <code>build-dep</code> to let apt install the required libraries for the program you will be compiling. For example, to install the development libraries for Kate, you can run:
| |
| | |
| {{Input|
| |
| sudo apt-get build-dep kate
| |
| }}
| |
| | |
| ==== Building with kdesrc-build ====
| |
| | |
| First, install distrobox and podman from your distribution repositories. Then run:
| |
| | |
| {{Input|
| |
| distrobox enter
| |
| }}
| |
| | |
| This should create a container based on your current Linux OS and enter it. It is preferable to use one of the Linux distributions that is better suited for kdesrc-build, as mentioned [[Get_Involved/development#Operating_system|in this wiki page]], so if your distribution does not provide very up-to-date packages, you can download and use a different container image for your distrobox from [https://hub.docker.com/search?type=image Dockerhub]. For example, with openSUSE Tumbleweed:
| |
| | |
| {{Input|
| |
| podman pull opensuse/tumbleweed
| |
| distrobox create --image opensuse/tumbleweed --name tumbleweed
| |
| distrobox enter tumbleweed
| |
| }}
| |
| | |
| Then it's a matter of downloading and running kdesrc-build as detailed in [[Get_Involved/development/Set_up_a_development_environment]]:
| |
| | |
| <syntaxhighlight lang="bash"> | |
| mkdir -p ~/kde/src
| |
| cd ~/kde/src
| |
| git clone https://invent.kde.org/sdk/kdesrc-build.git | |
| cd kdesrc-build
| |
| ./kdesrc-build --initial-setup
| |
| source ~/.bashrc
| |
| </syntaxhighlight> | |
| | |
| From this point on, one important thing to bear in mind is that a distrobox container is transparent in its user space and containerized in its root space: when you are inside a distrobox container, you can see the content of system's home folder, but not your system's root folders, only the container's root folders. This means that you can install packages inside the container using root privileges and access those packages to compile your programs stored in your home, without ever installing those packages in your actual system!
| |
| | |
| You can take advantage of this by installing, for instance, Qt development packages used for kdesrc-build from inside the container. This way, it is not necessary to compile Qt with kdesrc-build. This is particularly convenient if you want to compile KDE software with Qt6 quickly.
| |
| | |
| Likewise, you should [https://community.kde.org/Get_Involved/development/Install_the_dependencies install the required dependencies] from inside the distrobox rather than from your system's repositories. Then you can start compiling as usual.
| |
| | |
| After compiling your program with kdesrc-build from inside the distrobox, you can run it with <code>kdesrc-build run</code>, and despite it originating from inside a container and using the libraries from the container, it will run just fine as a GUI application on your system!
| |
| | |
| The only few gotchas to using this method are:
| |
| | |
| * You cannot use a [[Get_Involved/development/Build_software_with_kdesrc-build#Plasma|full Plasma Desktop session]] made from git.
| |
| * You will need qqc2-desktop-style and Breeze to show the correct theme for your applications.
| |
| * You will need the QtWayland library and its respective development package to run your applications natively on a Wayland session.
| |
| | |
| == Other operating systems ==
| |
| | |
| === Kubuntu 23.10 ===
| |
| | |
| The default configuration of kdesrc-build requires Qt version 6.5. Kubuntu 23.10 has Qt version 6.4.2. It is recommended that you use a [[Get_Involved/development#Operating_system|Linux OS that is better supported by kdesrc-build]].

| == Advanced kdesrc-build ==
| |
| | |
| After you have edited a git repository and you want to build it, <code>--no-src</code> will make sure that <code>kdesrc-build</code> does not overwrite your changes with the latest source code from the official git repository (remote "origin" / https://invent/kde.org).
| |
| | |
| <code>--no-include-dependencies</code> only builds the git repository that you give as parameter to <code>kdesrc-build</code>.
| |
| | |
| <code>--debug</code> shows verbose output.
| |
| | |
| <code>--refresh-build</code> forces a rebuild (not an incremental build) and a full reinstall.
| |
| | |
| E.g. you have edited kcalc. You run:
| |
| <pre>
| |
| kdesrc-build kcalc --no-src --no-include-dependencies --refresh-build --debug |& tee ~/a.txt
| |
| </pre> | | </pre> |

| |
| | |
| If you are interested in or need separate builds of KDE software, like when building with Qt5 or Qt6, you can create a self-contained, portable installation of kdesrc-build in its own folder. This way, you can manage your kdesrc-build configuration files each in their own environment without mixing configurations or having to rebuild the universe every time you want to test a different one.

kde-builder has replaced the previous KDE build framework named kdesrc-build.
Develop in a Linux container
When you start programming for KDE, it is recommended that you use kde-builder in your main operating system or in a virtual machine running on a Linux operating system that is better supported by kde-builder.
As an alternative, you can run kde-builder in a Linux container (docker, podman, toolbx, distrobox).
distrobox
It is possible to start developing KDE software using container images that are able to see inside your home folder. This can be done using distrobox and podman.
This solution is particularly useful for users on immutable distributions like Fedora Kinoite, openSUSE Kalpa or Valve's SteamOS 3
To learn how to build KDE software with distrobox, see: https://develop.kde.org/docs/getting-started/building/containers-distrobox/
Other operating systems
Kubuntu >= 24.10
The default configuration of kde-builder requires Qt version 6.7. Kubuntu 24.10 has Qt version 6.6. It is recommended that you use a Linux OS that is better supported by kde-builder.
If you are a more seasoned developer you might be able to use Kubuntu for kde-builder by installing Qt6 using the Qt online installer or by building Qt6 using kde-builder.
Alpine Linux
apk add git perl doas-sudo-shim
FreeBSD
Install the latest release of FreeBSD with KDE Plasma Desktop on your hardware computer or in a virtual machine.
Your user should be member of the "wheel" user group (e.g. this can be configured in the FreeBSD installer, when creating your user you can select additional user groups for your user). Your user should be able to use sudo:
pkg install sudo
visudo
# Uncomment the line: %wheel ALL=(ALL:ALL) ALL
Then set up kde-builder using the same procedure as when installing kde-builder on a Linux operating system. FreeBSD is currently supported by kde-builder. See https://www.youtube.com/watch?v=AhDHUg81M_I and https://www.youtube.com/watch?v=HRiKzaw8cAw .
OpenBSD >= 7.5
Install OpenBSD version greater than or equal to 7.5. In the installer keep the defaults, the user created by the installer is named "administrator" in this example.

After you install kde-builder:
# Edit the kdesrc-buildrc file e.g.:
cmake-options -DCMAKE_BUILD_TYPE=RelWithDebInfo -DKF_IGNORE_PLATFORM_CHECK=ON
# Also set environment variable:
export CMAKE_PREFIX_PATH=/usr/local/lib/qt6/cmake
# Or
export CMAKE_PREFIX_PATH=/usr/local/lib/qt5/cmake

kf6-qt6 vs. kf5-qt5
Many KDE git repositories can build correctly and run correctly using "kde-builder kf6-qt6".
The KDE git repositories that can build correctly and run correctly using "kde-builder kf6-qt6" have two long lived git branches:
- A long lived git branch that does not contain the deprecated symbols from kf5-qt5, named e.g. "master".
- And another long lived git branch for qt5-kf5, where the deprecated symbols still exist.
What is "kf6-qt6"? You just set up kde-builder following the procedure. The resulting kde-builder installation will be of type kf6-qt6. In kde-builder.yaml in the "global:" section you will have "branch-group: kf6-qt6". The git repositories that have only one long lived git branch e.g. named "master" will use that. The git repositories that have a second long lived git branch, will use the git branch where the deprecated symbols do not exist e.g. named "master".
What is "kf5-qt5"? Follow the chapter "kde-builder Qt5". The resulting kde-builder installation will be of type kf5-qt5. In kde-builder.yaml in the "global:" section you will have "branch-group: kf5-qt5". The git repositories that have only one long lived git branch e.g. named "master" will use that. The git repositories that have a second long lived git branch where the deprecated symbols still exist e.g. named "kf5" will use that.
Two independent kde-builder configurations: kf6-qt6 and kf5-qt5
You can switch between configurations with --rc-file
command line option. Generate another config, make the changes for the source-dir
, build-dir
, install-dir
,
and other changes you want. Make sure you use different value for persistent-data-file
option, to not mix things up.
As an alternative, you can utilize custom variable to make switch from a single config:
global
_ver 5 # <-- Change this to switch
source-dir ~/kde${_ver}/src
build-dir ~/kde${_ver}/build
install-dir ~/kde${_ver}/usr
persistent-data-file ~/kde${_ver}/persistent-options.json
end global
include ~/.local/share/kdesrc-build/data/build-include/kf${_ver}-qt${_ver}.ksb
Other CPU architectures than x86_64/amd64
You can build and develop KDE projects using a Linux OS installed on an ARM architecture CPU.
kde-builder issues
"kde-builder kpat" fails because of black-hole-solitaire
This happens on Debian/Ubuntu/Kubuntu. Because there is no Linux distribution binary package for https://github.com/shlomif/black-hole-solitaire.
Solution: append at the end of kdesrc-buildrc file:
options kpat
cmake-options -DWITH_BH_SOLVER=OFF
end options
