Installing binary packages

On Linux, using packages for your favorite distribution is the recommended way to get access to KDE Frameworks. Binary package distro install instructions.

Compiling from sources

The complete source code for KDE Frameworks 5.12.0 may be freely downloaded. Instructions on compiling and installing KDE Frameworks 5.12.0 are available from the KDE Frameworks 5.12.0 Info Page.

Building from source is possible using the basic cmake .; make; make install commands. For a single Tier 1 framework, this is often the easiest solution. People interested in contributing to frameworks or tracking progress in development of the entire set are encouraged to use kdesrc-build. Frameworks 5.12.0 requires Qt 5.2.

A detailed listing of all Frameworks and other third party Qt libraries is at inqlude.org, the curated archive of Qt libraries. A complete list with API documentation is on api.kde.org.


Those interested in following and contributing to the development of Frameworks can check out the git repositories, follow the discussions on the KDE Frameworks Development mailing list and contribute patches through review board. Policies and the current state of the project and plans are available at the Frameworks wiki. Real-time discussions take place on the #kde-devel IRC channel on freenode.net.

You can discuss and share ideas on this release in the comments section of the dot article.
