There are several ways to install KDE SC so that you can use and develop KDE software. Below are complete instructions for installing KDE4 on a Linux system based on whether you want an Official Release, a Nightly Build, Stable 4.x Release, or Trunk.
|Official Release||Nightly Build||Stable from Source||Trunk|
|For the casual user, or a developer who is working on applications outside of KDE SC||For application developers or package managers who are not modifying the core of KDE SC||For KDE SC and applications developers that want to spend less time setting up a build system||For developers working on core KDE SC functionality, and desire/need up-to-the-minute changes|
|1. Use a Distribution with KDE to set up a fully functional KDE system in one step. Also install the "developer packages" if you want to compile KDE software||1. Install build requirements from your distribution||1. Install build requirements from your distribution||1. Install build requirements from your distribution|
|2. Download and setup KDE SC easily using Project Neon||2. Download KDE source from SVN||2. Download KDE source from SVN|
|3. Build a stable 4.x release||3. Build KDE SC from trunk|
|4. Set up scripts to ease KDE development||4. Set up scripts to ease KDE development|
For instructions on installing KDE SC on Windows, BSD, or Mac OS X, or instructions for installing KDE3, please see the other supported platforms page. There are also upgrade instructions from a branch to trunk.
Below is additional information you may be interested in before installing KDE.
In each installation scenario above, Qt is installed in the most appropriate way. For your reference, there are three ways to install it:
Currently, KDE SC source code is accessed using svn, but in the future, we are migrating to Git. Amarok has already migrated to Git, as well as a few other modules (phonon, parts of kdesupport). Until we are fully migrated at least, it is recommended to use kdesrc-build if you can, as it takes care of all of this for you.
Compile and Linking errors are frequent sources of discouragement. Make careful note of the first occurrence of an error in your build process. It could be as simple as a bad environment variable, an unexpected version of a library or missing prerequisite.
If you are building from trunk and following the instructions linked from here or from Build KDE 4.5 on Kubuntu and would like free support, please contact:
You will likely want to use a stable package from your distribution instead of the ones of the KDE version you are working on.
For most development topics, and documentation, see Development
You may not need the latest bleeding-edge version of KDE with which to develop. Much of the code will be similar between versions and your patch might work. However, Trunk is where major changes are introduced, and branches are mostly for maintenance/bug fixes. In other words, it's best to either ask someone if they can either reproduce it in trunk (on IRC or what have you), and/or (if applicable), check bugs.kde.org for your issue.
If the patch is made against an older version of KDE (anything other than Trunk), but the issue still exists, post it to reviewboard as usual, and a developer will commit it to Trunk for you, and resolve any possible conflictions (since code gets reshuffled over time).
