== Abstract ==
== Introduction ==


Some or all of these packages should be available for installation [[build requirements|from your distribution]]. For ease of installation and upgrading it is a good idea to install distribution packages if a recent enough version is provided. Software required to build KDE4 includes:
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.


* gcc and g++, preferably version 4.2 or higher
=== Required Steps ===
* svn, the subversion revision control client
* pkg-config
* development libraries and headers for X11, OpenGL (mesa-common-dev and libglu1-mesa-dev), libjpeg, libpng, libungif, [http://download.librdf.org/source/ librdf], libxml2 and libxslt
* the <tt>makeobj</tt> script, which is included in kdesdk. You can install it from kdesdk (kdesdk-scripts on Debian) or similar packages, or download at [http://websvn.kde.org/*checkout*/trunk/KDE/kdesdk/scripts/makeobj WebSVN]
* the [http://freedesktop.org/wiki/Software/shared-mime-info shared-mime-info package], is the freedesktop MIME standard now used in KDE
* the [http://oscaf.sourceforge.net/ shared-desktop-ontologies package] is required to build and run all Nepomuk semantic desktop/desktop search modules.
* [http://boost.org/ boost], used by kdebase; after build and/or install, in order to make cmake aware about its location (FindBoost),  add the boost directory (which contains the include subdirectory) to CMAKE_INCLUDE_PATH or set a environment variable called BOOST_ROOT that points to the boost directory.
* [http://docbook.org/schemas/4x.html DocBook XML DTDs (v4.2)] and [http://wiki.docbook.org/topic/DocBookXslStylesheets related XSL stylesheets], used by KDE help system; their packages are available in most distributions


== D-Bus ==
You need to have completed the following steps:
D-Bus is the messaging framework used to allow different programs on the system to communicate with each other. It is used by both Qt and KDE.
* Set up your [[../Environment|Build Environment]]
* Selected your [[../Recipes|Build Recipes]]


Get [http://www.freedesktop.org/wiki/Software/dbus dbus] from your distribution, current stable release is version 1.4. Additionally you will also need dbus-glib. Be sure to also install the corresponding lib- and -devel packages.
== Definitions ==


D-Bus 1.4.0 or higher is highly recommended as it fixes a bug when multiple threads access the same session bus. D-Bus 1.2 series should work (aside from that issue) but you should upgrade as soon as feasible.
The Build Requirements for each Module will be documented in a common table format as follows:


== CMake ==
{| border="1" cellpadding="5" cellspacing="0"
You need to have [http://cmake.org/ CMake] >=2.6.4 installed.  
|+ '''Build Requirements'''
You should be able to directly use the binary packages available on the [http://cmake.org/HTML/index.html CMake site]. There are also distribution specific packages available.

| A library to enable KDE Software to foo your bar.
|}


== Qt ==
The fields in this table are defined as follows:
Next we need to get Qt4. KDE 4.5 builds against Qt 4.6, however KDE trunk requires Qt 4.7. If you plan to build trunk on an ongoing basis, it is probably easier to track kde-qt, especially as KDE trunk may occasionally require a pre-release version of Qt.


Most up-to-date distributions will have packages of sufficiently new Qt to build the latest KDE stable branch. Some distributions may even package kde-qt; if so, using it is a viable option. If the distribution you use does not provide packages of the necessary version of Qt, it will be necessary to use the recipe below. More information can be found in the sections of the tutorial specific to each distribution.

; README
TODO: Complete updating this list
Please read the [http://qt.gitorious.org/+kde-developers/qt/kde-qt/blobs/master/README.kde-qt README.kde-qt] file for the necessary Qt configure options as well as currently known issues.


=== The Recipe ===
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.
cs    # Note: cs is not a typo. See [[Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc|<font color=red>.bashrc</font>]]
git clone git://gitorious.org/+kde-developers/qt/kde-qt.git qt-kde
cd qt-kde
./configure ''[copy/paste configure line from README.kde-qt replacing <installdir> with $QTDIR]''
make -j2 # use 'make -j(X+1)' where X is your number of processors, to compile faster
make install


Note that you need to install Qt and Phonon from Qt and then later to install Phonon KDE from git at the same location. This will ensure you get sounds in Qt-based applications as well as in KDE ones.
Requirements as at 2011-03-02.


If ./configure produces errors about missing headers, run the following command before trying again: <code>QTDIR=`pwd` bin/syncqt</code>

'''Make sure <tt>which qmake</tt> delivers something out of $QTDIR, e.g.:'''
=== Hardware Libraries ===
  /home/kde-devel/qt-kde/bin/qmake
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.   


=== What's Happening ===
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.
We switch back to the <tt>kde-devel</tt> user's home directory (line 1) and download the source code, KDE branch, from gitorious using git (line 2). After changing into the resulting {{path|qt-kde}} directory (line 3), we then set up the build using the <tt>configure</tt> script (line 4). The various command line options used are explained in the {{path|qt-kde/README.kde-qt}} file. Finally, we build the minimal requirements for KDE (line 6) and install (line 9) Qt. If install dir is the same as the current dir (line 7), then we just free some space (line 8) instead. If you want all the example and demo applications, you can either build them individually or simply do a <tt>make</tt> from the {{path|qt-kde}} directory.  


Note that the installation does not require root as it installs Qt locally into {{path|$QTDIR}}. Installation is necessary if {{path|$QTDIR}} differs from the source directory.
=== Distributions ===
In the end, we make sure the cmake macro to find the Qt directory will work. It must be able to find qmake in $QTDIR.


=== Troubleshooting ===
Many distributions provide shortcut meta-packages or install commands to simplify installing all the KDE requirements.  Check the [[Getting_Started/Build/Distributions|Distributions page]] first to see if your distribution provides a simple way to install the requirements.
If you get "error: X11/Xlib.h: No such file or directory", install the devel package of <tt>xorg</tt> (the actual name may vary between operating systems, for example it is <tt>xorg-dev</tt> on Ubuntu based systems such as Kubuntu).  


If you get an error in the configure step about missing defines, check the value of <tt>$QMAKESPEC</tt>.  Some distributions set this to point directly to the system-installed Qt.  If <tt>unset QMAKESPEC</tt> solves the problem, you probably want to add it to the <tt>~/.bashrc</tt> script.
== Shared-Desktop-Ontologies ==
 
If you get an error ".pch/debug-shared/QtCore", this is because Qt-4.3 enables precompiled headers if your gcc supports it, but for some reason it doesn't work for you. If you use distcc, configure qt with -no-pch. If you use icecream, update to the latest icecream from svn trunk.
 
Try running any Qt program, like {{program|assistant}}. '''Note:''' You may need to run <tt>xhost +local:kde-devel</tt> as your regular kde3 user to run this application.  If it crashes in QSpanData::adjustSpanMethods, then your problem is the oxygen style. Try removing {{path|lib/kde4/plugins/styles/kstyle-oxygen.so}} and {{path|lib/kde4/plugins/styles/oxygen.so}} if they exist in the KDE install prefix.
 
=== Generating local API documentation ===
It's nice to have the Qt documentation locally for nice integration with [[Getting_Started/Set_up_KDE_4_for_development#KDevelop|KDevelop]], and doing this is really quite easy (also shown in {{path|README.kde-qt}}):
cd $KDE_SRC/qt-kde
make docs
./config.status
make install
Note that it is necessary to do this only once, even if you rebuild Qt later.
 
== HAL ==
 
{{tip|You can use qdbusviewer to see if you have org.freedesktop.hal. If not, you might need a newer version of hal. If you have org.freedesktop.hal, you probably don't need to, and don't ''want'' to, roll your own HAL.}}
 
If your system requires you to build a newer version of HAL, there's a decent chance you'll need to build other stuff as well, some of which may not be straight forward. This, however, should only be required for older distros.
 
== kdesupport Git dependencies ==
 
===Automoc ===
git clone git://anongit.kde.org/automoc.git
 
Please see [http://projects.kde.org/projects/kdesupport/automoc http://projects.kde.org/projects/kdesupport/automoc]
 
Please note that automoc should be built '''FIRST''' from git as a kdesupport dependency.
 
===Attica ===
git clone git://anongit.kde.org/attica.git
 
Please see [http://projects.kde.org/projects/kdesupport/attica http://projects.kde.org/projects/kdesupport/attica]
 
===Polkit Qt===
git clone git://anongit.kde.org/polkit-qt-1.git
 
It is recommended to have '''polkit >= 0.98''', however Polkit-Qt-1 will build with any polkit-1 version.
 
Please see [http://projects.kde.org/projects/kdesupport/polkit-qt-1 http://projects.kde.org/projects/kdesupport/polkit-qt-1]
 
===Soprano===
git clone git://anongit.kde.org/soprano.git
 
Please see [http://projects.kde.org/projects/kdesupport/soprano http://projects.kde.org/projects/kdesupport/soprano]
 
=== Akonadi ===
git clone git://anongit.kde.org/akonadi.git
 
Please see [http://projects.kde.org/projects/kdesupport/akonadi http://projects.kde.org/projects/kdesupport/akonadi]
 
Please note that Akonadi should come '''AFTER Soprano''' in the build.
 
===Cagibi===
Cagibi is a runtime dependency for UPnP.
 
git clone git://anongit.kde.org/cagibi.git
 
Please see [http://projects.kde.org/projects/kdesupport/cagibi http://projects.kde.org/projects/kdesupport/cagibi]
 
----
 
''For all the above you build by doing'':
cd <dir> (<dir> being either automoc, akonadi, attica, polkit-qt-1 or soprano or cagibi)
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$KDEDIR -DCMAKE_BUILD_TYPE=debugfull  \-DKDE4_BUILD_TESTS=TRUE
make
make install
 
=== RSA Key fingerprint for git.kde.org===
c8:45:ba:89:85:11:78:b5:a4:09:d9:31:f6:7f:7c:79
 
== kdesupport svn dependencies ==
 
{{warning|Don't forget to read the [[Getting_Started/Build/KDE4#Setting_up_the_environment|Setting Up The Environment]] section first.}}
 
There are several libraries that KDE applications rely on in the kdesupport module. This includes Strigi and Soprano for file metadata and search, QImageBlitz for image manipulation needed in kdebase, eigen for visual effects in applications such as Kalzium, taglib for music players and qca for some cryptographic needs.
 
Strigi itself has a few dependencies as well: you will need the libraries and headers for libz, libbz2, openssl (libcrypto or libssl), libclucene (>=0.9.16a but watch out: version 0.9.17 does '''not''' work), and either libxml2 or libexpat.
 
[[Getting_Started/Build/KDE4/Prerequisites#DBusMenu|'''Phonon''']] is not in kdesupport anymore but in a git repository.
 
Some dependencies moved from svn kdesupport to KDE git repository, see below.
 
There is a new dependency: [[Getting_Started/Build/KDE4/Prerequisites#DBusMenu|'''DBusMenu''']].
 
Please remember that if you use openSUSE, you can install the needed packages from the KDE:KDE4 buildservice repository and do not have to bother with fiddling the details below. Skip to the kdelibs section.
 
=== The Recipe ===
<!--'cs' and 'cb' are NOT typos!-->
cs # [[Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc|'cs' is a bash function, click here to learn more]]
svn checkout svn://anonsvn.kde.org/home/kde/trunk/kdesupport/
cd kdesupport
cmakekde
 
=== What's Happening ===
We change to the base source directory (line 1). We download the sources in kdesupport using subversion (line 2), go into the new {{path|~/kde/src/kdesupport}} directory (line 3), and commence the build (line 4). This will leave us in the kdesupport build directory after the build is completed.
 
=== Troubleshooting ===
If you get
  cmakekde: command not found
then you have to go manually into the kdesupport directory in ~ and execute the command cmakekde. if this still doesn't work, then something is wrong with your bashrc.
 
If you get
CMake Error: This project requires some variables to be set,
and cmake can not find them.
Please set the following variables:
LIBXML2_INCLUDE_DIR (ADVANCED)
you should install the development package for libxml2.
 
If you get
CMake Error: Could NOT find REDLAND
then you need librdf from the Redland.
If your distribution does not provide the librdf package, you can download the source there: [http://download.librdf.org/source/ http://download.librdf.org/source/] and build it.
(Gentoo users: The ebuild for librdf is named dev-libs/redland)
 
If you get
Fetching external item into 'kdesupport/admin'
Error validating server certificate for 'https://...'
see [[Getting_Started/Sources/Using_Subversion_with_KDE|Using Subversion with KDE]]
 
If you get
FILE cannot create directory: /usr/lib[64]/qt4/plugins/crypto. Maybe need administrative privileges.
make: *** [install] Error 255
take a second look in the .bashrc file described above, are paths correct?  ($QTDIR and $PATH are used to get the QT installation path)
Alternatively, you may see this error if you decided to use a distribution installed version of qt4 and skipped the Qt install above.  Either install qt-kde as describe above, or "sudo make install". If you use "sudo make install", make sure that you change the ownership back to your user for some of the ~/kde subdirectories that were effected by using sudo (ie. "<tt>sudo chown -R kde-devel:kde-devel ~/kde</tt>").
 
If you get a message related to
  target libQtTest.so not found
you may need to recompile qt-kde. This time you should take out
  -nomake demos -nomake examples
from the configure command, so that Qt generates library QtTest.


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


If you get
{| border="1" cellpadding="5" cellspacing="0"
      CMake Error: Qt qmake not found!
|+ '''KDE Software Build Requirements'''
Then:
|-
      1) uncomment Qt section in .bashrc script (QTDIR, QT_PLUGINS_DIR,

If you get
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.
      "CMake Error: Could NOT find BZip2"
then
      sudo apt-get install libbz2-dev
or
      urpmi libbzip2_1-devel


If you get
To obtain the source you can either download a tarball from the website or use the following git command:
      message that MySql support cannot be enabled
then
      you need to install corresponding devel package. (libmysqlclient-devel  for SuSe 11.1)
 
== Phonon ==
You need to build it as Phonon from Qt is not enough for KDE sound to work.
 
=== The Recipe ===
<!--'cs' and 'cb' are NOT typos!-->
cs # [[Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc|'cs' is a bash function, click here to learn more]]
git clone git://anongit.kde.org/phonon
cd phonon
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$QTDIR -DCMAKE_BUILD_TYPE=debugfull \-DKDE4_BUILD_TESTS=TRUE
make
make install
 
'''Note''' that you need to install this Phonon in the same location than Phonon from Qt i.e. in $QTDIR.
 
Building the main Phonon module is sufficient for building KDE.  If you also want to play sound then you need to build a backend.  Choose a suitable backend from those available below:
 
git clone git://anongit.kde.org/phonon-directshow
git clone git://anongit.kde.org/phonon-gstreamer
git clone git://anongit.kde.org/phonon-mmf
git clone git://anongit.kde.org/phonon-quicktime
git clone git://anongit.kde.org/phonon-waveout
git clone git://anongit.kde.org/phonon-xine
 
=== Troubleshooting ===
 
If you get an error like
 
designer: symbol lookup error: /path/to/kde/lib/kde4/plugins/phonon_backend/phonon_xine.so: undefined symbol: _ZN6Phonon12PulseSupport11getInstanceEv
 
while running Qt Designer you need to:
 
rm $QTDIR/lib/libphonon.so.4
 
== DBusMenu ==
 
Since the 26th April 2010, DBusMenu is a new dependency for kdebase. You can either get it from
http://people.canonical.com/~agateau/dbusmenu/index.html
as a tarball (latest is libdbusmenu-qt-0.6.3.tar.bz2)
or from its it repository
 
=== The Recipe ===
<!--'cs' and 'cb' are NOT typos!-->
cs # [[Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc|'cs' is a bash function, click here to learn more]]
git clone git://gitorious.org/dbusmenu/dbusmenu-qt.git dbusmenu
cd dbusmenu
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$KDEDIR -DCMAKE_BUILD_TYPE=debugfull \-DKDE4_BUILD_TESTS=TRUE
make
make install
=== Troubleshooting ===
You need json to build the tests.
 
If your version is not correct, you will lose the context menu for the systray icons.
 
== Shared-Desktop-Ontologies ==
Website: http://sourceforge.net/projects/oscaf/files/


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

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

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
