=== Qt 5 ===
 
Qt 5 (http://qt-project.org/) is the base of KDE software. You can either make an own Qt 5 build or use the pre-built development packages of your distribution. The next two sections show both ways. Choose one of them.
 
 
 
==== Either: Make own Qt5 build ====
 
* PRO: full control and debugging capabilities
 
* CON: takes long to compile on the first time, might be an additional source of errors for beginners
 
 
 
To build all of qt5 execute:
 
<syntaxhighlight lang="bash">
 
git clone git://anongit.kde.org/qt/qt5.git --branch 5.3
 
cd qt5
 
./init-repository
 
./configure -prefix $PWD/qtbase -opensource -confirm-license -nomake tests -nomake examples -dbus -no-separate-debug-info -xcb -qpa xcb -no-gtkstyle -developer-build
 
make
 
</syntaxhighlight>
 
 
 
To update qt5 later:
 
<syntaxhighlight lang="bash">
 
git pull
 
git submodule sync
 
git submodule update --recursive
 
</syntaxhighlight>
 
 
 
If you saw changes (i.e. qt5.git got updated since last time),
 
<syntaxhighlight lang="bash">
 
./configure [...same as above...]
 
make
 
echo $?    # you should make extra sure that 'make' didn't abort with an error, especially when using -j
 
</syntaxhighlight>
 
 
 
Experimental and not officially supported: if you don't have enough time and disk space for all of qt5, you could restrict yourself to separate checkouts of qtbase.git, qtsvg.git, qtx11extras.git, qtscript.git and qttools.git, this is enough to build  frameworks/* (but not enough for plasma-framework).
 
 
 
<b>NOTE for ArchLinux users</b>: qtwebkit uses python to generate some files, but it uses python2 syntax. So you have to either [https://projects.archlinux.org/svntogit/packages.git/plain/trunk/use-python2.patch?h=packages/qt5 patch the qtwebkit code] or make /usr/bin/python point to /usr/bin/python2. See also https://wiki.archlinux.org/index.php/Python
 
 
 
==== Or: use pre-built development packages ====
 
* PRO: faster to get started, one source of errors less
 
 
 
Note that the Qt version currently must be >= 5.3
 
 
 
1) openSUSE 13.1:
 
* add the repository http://download.opensuse.org/repositories/KDE:/Qt53/openSUSE_13.1/
 
* install packages:
 
$ sudo zypper install libqt5-qttools libgypsy0 libqt5-creator libqt5-linguist libqt5-qtbase-common-devel libqt5-qtbase-debugsource libqt5-qtbase-devel libqt5-qtbase-doc libqt5-qtbase-examples libqt5-qtdeclarative-debugsource libqt5-qtdeclarative-devel libqt5-qtdeclarative-examples libqt5-qtdeclarative-tools libqt5-qtdoc libqt5-qtgraphicaleffects libqt5-qtimageformats libqt5-qtimageformats-debugsource libqt5-qtimageformats-devel libqt5-qtmultimedia-devel libqt5-qtmultimedia-examples libqt5-qtquick1-devel libqt5-qtquickcontrols libqt5-qtscript-devel libqt5-qtscript-examples libqt5-qtsvg-devel libqt5-qttools-debugsource libqt5-qttools-devel libqt5-qtx11extras-devel libqt5-qtxmlpatterns-devel libqt5-qtxmlpatterns-examples libQt5CLucene5 libQt5Concurrent-devel libQt5Concurrent5 libQt5Core-devel libQt5Core5 libQt5DBus-devel libQt5DBus5 libQt5Declarative5 libQt5Designer5 libQt5DesignerComponents5 libQt5Gui-devel libQt5Gui5 libQt5Help5 libQt5Multimedia5 libQt5Network-devel libQt5Network5 libQt5OpenGL-devel libQt5OpenGL5 libQt5Positioning5 libQt5PrintSupport-devel libQt5PrintSupport5 libQt5Script5 libQt5Sensors5 libQt5Sql-devel libQt5Sql5 libQt5Sql5-mysql libQt5Sql5-postgresql libQt5Sql5-sqlite libQt5Sql5-unixODBC libQt5Svg5 libQt5Test-devel libQt5Test5 libQt5WebKit5 libQt5WebKitWidgets5 libQt5Widgets-devel libQt5Widgets5 libQt5X11Extras5 libQt5Xml-devel libQt5Xml5 libQt5XmlPatterns5 libQtQuick5 Qt5WebKitWidgets-devel libqt5-qtbase-private-headers-devel
 
(these might be too much packages but with those the KF5 build worked)
 
 
 
2) Other distributions: yet to be documented.
 
 
 
= Build KDE Frameworks and its dependencies =
 
== Git remote prefix ==
 
Let's setup a "kde:" prefix for git commands. Add the following text to your ~/.gitconfig:
 
<syntaxhighlight lang="ini">
 
[url "git://anongit.kde.org/"]
 
  insteadOf = kde:
 
[url "ssh://[email protected]/"]
 
  pushInsteadOf = kde:
 
</syntaxhighlight>
 
 
 
== Clone kdesrc-build ==
 
First you need kdesrc-build, it can be done with the following commands:
 
<pre>
 
mkdir -p extragear/utils
 
git clone kde:kdesrc-build extragear/utils/kdesrc-build
 
ln -s extragear/utils/kdesrc-build/kdesrc-build .
 
</pre>
 
 
 
== Download the configuration file ==
 
At this point,
 
# download http://www.davidfaure.fr/kde/kf5-qt5-kdesrc-buildrc into your source dir
 
# rename it to '''kdesrc-buildrc'''
 
You can use this command:
 
<pre>
 
wget "http://www.davidfaure.fr/kde/kf5-qt5-kdesrc-buildrc" -O "kdesrc-buildrc"
 
</pre>
 
== Adjust the paths ==
 
Take a look at those lines in the configuration file you've downloaded:
 
<pre>
 
  qtdir /d/qt/5/kde/qtbase
 
  source-dir /d/kde/src/5
 
  build-dir /d/kde/build/5
 
  kdedir /d/kde/inst/kde_frameworks
 
</pre>
 
and adjust the paths the way you want.
 
* qtdir = Where Qt 5 is installed, or qtbase build dir if using uninstalled
 
* source-dir = where KDE Frameworks 5 sources should be downloaded
 
* build-dir = where KDE Frameworks 5 should be built
 
* kde-dir = your KDE Frameworks 5 installation directory
 
 
 
{{Note|The value of <tt>'''''kde-dir'''''/share</tt> must be included in the environment variable <tt>'''XDG_DATA_DIRS'''</tt> or otherwise the build will fail. kdesrc-build should handle this for you.}}
 
{{Note|The Qt dir must be included in the environment variable <tt>'''CMAKE_PREFIX_PATH'''</tt> otherwise kdesrc-build will fail to configure most modules.}}
 
 
 
== Build kdesrc-build ==
 
{{Note|Note that this script uses GIT and Bazaar to download the sources, so ensure you have both installed. }}
 
You just have to run <code>./kdesrc-build</code> to build the KDE Frameworks.
 
It is the preferred way of building KDE Frameworks.
 
 
 
{{Note|kdesrc-build will only pick up the kdesrc-buildrc file you downloaded and edited above if it is in the same directory you run kdesrc-build from.  If you save it to ~/.kdesrc-buildrc, however, it will be used no matter where you run kdesrc-build from. }}
 
 
 
If you want you can also do the work by hand following the detailed instructions: [[Frameworks/Building/Details]].
 
 
 
== Use project neon 5 tools ==
 
Project Neon 5 in KUbuntu provides neon5-env and neon5-cmake tools which makes building KDE Frameworks easy. For more details see: http://community.kde.org/Frameworks/Building/ProjectNeon5
 
 
 
= Runtime setup =
 
To use your new KF5 install prefix (let's call it $KF5) :
 
<syntaxhighlight lang="bash">
 
export KF5=<path to your intended frameworks install directory>
 
export QTDIR=<path to your qt5 install dir, or qtbase build dir if using uninstalled>
 
export XDG_DATA_DIRS=$KF5/share:$XDG_DATA_DIRS:/usr/share
 
export XDG_CONFIG_DIRS=$KF5/etc/xdg:$XDG_CONFIG_DIRS:/etc/xdg
 
export PATH=$KF5/bin:$QTDIR/bin:$PATH
 
export QT_PLUGIN_PATH=$KF5/lib/plugins:$KF5/lib64/plugins:$KF5/lib/x86_64-linux-gnu/plugins:$QTDIR/plugins:$QT_PLUGIN_PATH
 
#  (lib64 instead of lib, on OpenSUSE and similar)
 
export QML2_IMPORT_PATH=$KF5/lib/qml:$KF5/lib64/qml:$KF5/lib/x86_64-linux-gnu/qml:$QTDIR/qml
 
export QML_IMPORT_PATH=$QML2_IMPORT_PATH
 
export KDE_SESSION_VERSION=5
 
export KDE_FULL_SESSION=true
 
</syntaxhighlight>
 
 
 
Note that LD_LIBRARY_PATH isn't set. You shouldn't set it, the builtin rpath works magic instead, and if you set it you'll have issues when running tools that use uninstalled libs while building frameworks (e.g. meinproc, kconfig_compiler...)
 
 
 
To use separate user settings for KF5:
 
<syntaxhighlight lang="bash">
 
export XDG_DATA_HOME=$HOME/.local5/share
 
export XDG_CONFIG_HOME=$HOME/.config5
 
export XDG_CACHE_HOME=$HOME/.cache5
 
</syntaxhighlight>
 
 
 
To be able to compile other stuff on top of KF5:
 
<syntaxhighlight lang="bash">
 
export CMAKE_PREFIX_PATH=$KF5:$CMAKE_PREFIX_PATH
 
</syntaxhighlight>
 
 
 
To get more information out of qDebug statements (i.e. make it more like kDebug) :
 
<syntaxhighlight lang="bash">
 
export QT_MESSAGE_PATTERN='%{appname}(%{pid})/%{category} %{function}: %{message}'
 
</syntaxhighlight>
 
or even better, to get colors:
 
<syntaxhighlight lang="bash">
 
c=`echo -e "\033"`
 
export QT_MESSAGE_PATTERN="%{appname}(%{pid})/(%{category}) ${c}[31m%{if-debug}${c}[34m%{endif}%{function}${c}[0m: %{message}"
 
unset c
 
</syntaxhighlight>
 
 
 
Don't bother with KDEDIR and KDEHOME etc.  this stuff isn't used anymore.
 
 
 
= Running unit tests =
 
Unit tests are ran from the build dir of each framework, you should first cd into it.
 
 
 
You need a separate DBus session because the dbus server needs to have the right value of XDG_DATA_DIRS, in order to find $KF5/share/dbus-1/services for starting services (e.g. kded5).
 
 
 
<pre>
 
eval `dbus-launch`
 
kdeinit5
 
make test
 
</pre>
 
 
 
Warning: never start a KDE 4 application in this separate DBus session, it would conflict with your running Plasma 4 desktop.
 
Note: KDE_FULL_SESSION=true is needed to make sure that the correct QPA will be loaded.
 
 
 
Many of the tests require an X server, and will pop up windows briefly.  An easy way to allow these tests to run without interfering with your normal X session is to do <pre>
 
xvfb-run -s '-screen 0 1024x768x24' make test
 
</pre>
 
(the -s argument tells Xvfb to set the first screen to be 1024x768 pixels, with a depth of 24; at least one test requires a depth greater than 8).  In this case, if you also ensure <tt>DBUS_SESSION_BUS_ADDRESS</tt> is not set, the tests should not find your existing D-Bus session, and instead launch a new D-Bus instance.
 
 
 
Note that the KWindowSystem tests require a NETWM-compatible window manager to be running.  One way to do this is to create a script to run such a window manager, followed by whatever is passed to it.  For example, if you have the window manager [http://awesome.naquadah.org/ awesome] installed, you could create a script called <tt>awesome-run</tt> as follows: <syntaxhighlight lang="bash">
 
#!/bin/sh
 
awesome &
 
 
</syntaxhighlight>
 
and then run the tests as <pre>
 
xvfb-run -s '-screen 0 1024x768x24' /path/to/awesome-run make test
 
</pre>
 
 
 
If you want to publish your test results, instead of "make test" run <pre>
 
make Experimental
 
</pre>
 
The test results will appear on http://my.cdash.org/index.php?project=&lt;projectname&gt;
