Building KDE4 From Source/Requirements

Introduction

This page details the software requirements that need to be installed on your system before you can start building KDE Software. For most of these requirements it is preferable to use your distribution supplied packages, however in some case you will need to build some requirements yourself and this page will also explain how to do so.

Required Steps

You need to have completed the following steps:

Set up your [[../Environment|Build Environment]]
Selected your [[../Recipes|Build Recipes]]

Definitions

The Build Requirements for each Module will be documented in a common table format as follows:

**Build Requirements**
Requirement	Stable Requires	Unstable Requires	Devel Pkgs?	Details
Foobar	>= 2.0	>= 1.0	Yes	A library to enable KDE Software to foo your bar.

The fields in this table are defined as follows:

Requirement	The project that KDE Software depends on, including a link to the Project home page.]
Stable Requires	The version of the Project that the current Stable KDE Release requires. The background color indicates if the requirement is optional (green) or mandatory (red). Stable is currently KDE Release 4.6.
Unstable Requires	The version of the Project that the current Unstable development version requires. The background color indicates if the requirement is optional (green) or mandatory (red). Unstable is currently targeting KDE Release 4.7.
Devel Pkgs?	If installing from distribution packages, whether you also need to install the -devel packages.
Details	More information about the Project and the requirement

System Prerequisites

TODO: Complete updating this list

All of these packages should be installed from your distribution. If you cannot meet these requirements from your distribution, it is recommended to either update to a more recent distribution or to build KDE in a virtual machine.

Requirements as at 2011-03-02.

**KDE Software Build Requirements**
Requirement	Stable Requires	Unstable Requires	Devel Pkgs?	Details
GCC / G++	>= 4.2	>= 4.2	No
Git			No	Revision control software, required for development builds.
Subversion			No	Revision control software, required for development builds.
pkg-config	>=	>=	No
CMake	>= 2.6.4	>= 2.6.4	No	Build configuration tool
DBus	>= 1.4.0	>= 1.4.0	Yes	Also dbus-glib
X11	>=	>=	Yes
Mesa	>=	>=	Yes	mesa-common-dev and libglu1-mesa-dev
libjpeg	>=	>=	Yes
libpng	>=	>=	Yes
libungif	>=	>=	Yes
librdf	>=	>=	Yes
libbz2	>=	>=	Yes
libxml2	>=	>=	Yes
libxslt	>=	>=	Yes
Boost	>=	>=	Yes
libmysqlclient	>=	>=	Yes
shared-mime-info	>=	>=	Yes
Shared-Desktop-Ontologies	>=	>=	No
DocBook XML DTD's	>= 4.2	>= 4.2	No	Required for the KDE documentation and help
DocBook XSl Stylesheets	>= 4.2	>= 4.2	No	Required for the KDE documentation and help

Hardware Libraries

HAL (Hardware Abstraction Layer) is required by KDE 4.5 and earlier for interfacing with your hardware. Your distribution supplied packages should be sufficient for this.

From KDE 4.6 onwards HAL has been deprecated in favor of uDisk, uPower and related projects, but all but the most recent distributions will still require HAL.

Distributions

Many distributions provide shortcut meta-packages or install commands to simplify installing all the KDE requirements. Check the Distributions page first to see if your distribution provides a simple way to install the requirements.

Shared-Desktop-Ontologies

The Ontologies are a shared resource required for the semantic desktop.

**KDE Software Build Requirements**
Requirement	Stable Requires	Unstable Requires	Devel Pkgs?	Details
Shared-Desktop-Ontologies	>=	>= 0.7	No

Your distribution packages should be sufficient for this package but some older distributions may not have them so you may need to build them yourself using either the Easy Recipe or Full Recipe.

To obtain the source you can either download a tarball from the website or use the following git command:

git clone git://oscaf.git.sourceforge.net/gitroot/oscaf/shared-desktop-ontologies

Next Step

Once all requirements have been installed it is time to install Qt
