This section provides information about '''hard''' (required) and '''optional''' software packages needed to build the KDE Framework.
 
 
 
=== Kdelibs packages ===
 
*'''deb-based distributions (Debian, Ubuntu...):''' All the dependencies used for the packages can be installed by running
 
$ apt-get build-dep {packagename}
 
*for instance on Ubuntu:
 
$ sudo apt-get build-dep kdelibs5
 
 
 
*'''OpenSuSE:''' All the dependencies used for building kdelibs can be installed by running:
 
$ zypper si -d kdelibs5
 
 
 
*'''Fedora:''' All the dependencies used for building kdelibs can be installed by running:
 
$ yum-builddep kdelibs5
 
 
 
=== CMake 2.10.1 ===
 
You need CMake 2.10.1 for KDE Frameworks 5. If you are already using 2.10.1 you can move on to next step
 
else download it from http://www.cmake.org/cmake/resources/software.html.
 
 
 
Alternative for CMake 2.10.1 using Git.
 
 
 
* Choose an install prefix, for instance
 
  $ export KF5=$HOME/kf5
 
 
 
To avoid repetition of command you can append ~/.bashrc file with above line and execute,
 
  $ source ~/.bashrc 
 
* Checkout and install Latest version of CMake using Git.
 
  $ git clone git://cmake.org/cmake.git
 
  $ cd cmake
 
  $ ./configure --prefix=$KF5
 
  $ make
 
  $ make install
 
 
 
=== Extra CMake Modules ===
 
 
 
* Checkout and build extra-cmake-modules
 
  $ git clone git://anongit.kde.org/extra-cmake-modules
 
  $ cd extra-cmake-modules
 
  $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 .
 
  $ make
 
  $ make install
 
 
 
= Build KDE frameworks =
 
Current state of KDE framework exist in frameworks branch of kdelibs.
 
 
 
To retrieve the source code from Git you have to use the following setup.Add the following text to your ~/.gitconfig:
 
  [url "git://anongit.kde.org/"]
 
    insteadOf = kde:
 
  [url "ssh://[email protected]/"]
 
    pushInsteadOf = kde:
 
Then execute
 
  $ git clone kde:kdelibs --branch frameworks
 
  $ mkdir  kdelibs/build
 
  $ cd kdelibs/build
 
  $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_SYSTEM_PREFIX_PATH=/usr:/usr/local:$KF5 ..
 
  $ make
 
  $ make install
 
 
 
Updating the already built framework.
 
If the source code has been checked from a branch, it is possible to update the source code with newly added changes and build again. Usually only changing parts will be built, so this operation would be faster than building the source code from scratch.
 
 
 
Go to your source directory and execute following commands.
 
  $ git pull --rebase
 
  $ cd build
 
  $ make
 
  $ make install
 
 
 
= Runtime setup =
 
To use your new KF5 install prefix (let's call it $KF5) :
 
<pre>
 
export XDG_DATA_DIRS=$KF5/share:$XDG_DATA_DIRS
 
export XDG_CONFIG_DIRS=$KF5/etc/xdg:$XDG_CONFIG_DIRS
 
export PATH=$KF5/bin:$PATH
 
export QT_PLUGIN_PATH=$KF5/lib/plugins:$QTDIR/plugins:$QT_PLUGIN_PATH
 
  (lib64 instead of lib, on OpenSUSE)
 
</pre>
 
 
 
To use separate user settings for KF5:
 
<pre>
 
export XDG_DATA_HOME=$HOME/.local5
 
export XDG_CONFIG_HOME=$HOME/.config5
 
export XDG_CACHE_HOME=$HOME/.cache5
 
</pre>
 
 
 
To be able to compile other stuff on top of KF5:
 
<pre>
 
export CMAKE_PREFIX_PATH=$KF5:$CMAKE_PREFIX_PATH
 
</pre>
 
 
 
Don't bother with KDEDIR and KDEHOME etc.  this stuff isn't used anymore.
 
 
 
= Running unit tests =
 
<pre>
 
eval `dbus-launch`
 
kdeinit5
 
make test
 
</pre>
 
 
 
= Building KDE frameworks with Qt 5 =
 
 
 
The recommended way to do this is to install Qt5, Phonon 5, and the patched libdbusmenu-qt in your $KF5 directory, and pass -DCMAKE_PREFIX_PATH=$KF5 to cmake when building KDE Frameworks. More details below.
 
 
 
To build qt5 execute:
 
  $ git clone git://gitorious.org/qt/qt5.git
 
  $ cd qt5
 
  $ ./init-repository
 
  $ mkdir build
 
  $ cd build
 
  $ ../configure -prefix $KF5 -opensource -confirm-license -nomake examples -qpa xcb -no-gtkstyle
 
  $ make
 
  $ make install
 
 
 
At this point you can continue building things by hand, or download http://www.davidfaure.fr/2012/kf5-qt5-kdesrc-buildrc into your source dir, adjust the paths and run kdesrc-build.
 
 
 
To build phonon by hand execute:
 
  $ git clone kde:phonon --branch five
 
  $ mkdir phonon/build
 
  $ cd phonon/build
 
  $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_PREFIX_PATH=$KF5 ..
 
  $ make
 
  $ make install
 
 
 
To build the patched libdbusmenu-qt execute:
 
  $ bzr branch lp:libdbusmenu-qt
 
  $ wget http://www.davidfaure.fr/2012/libdbusmenu-qt.diff
 
  $ cd libdbusmenu-qt
 
  $ patch -p0 -i ../libdbusmenu-qt.diff
 
  $ mkdir build
 
  $ cd build
 
  $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_PREFIX_PATH=$KF5 ..
 
  $ make
 
  $ make install
 
 
 
At this point, building KDE Frameworks works just the same as with Qt4.
 
 
 
== Qt5-specific setup instructions ==
 
<pre>
 
export QT_MESSAGE_PATTERN='%{appname}(%{pid})/%{category} %{function}: %{message}'
 
</pre>
 
so that qDebug behaves almost like kDebug.
