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
 
= Running unit tests =
 
<pre>
eval `dbus-launch`
kdeinit5
make test
</pre>
 
= Building KDE frameworks with Qt 5 =
 
This is experimental and not the recommended way to contribute to KDE Frameworks at this point.
 
Make sure to pass -DQT5_BUILD=TRUE to cmake.
 
You might have to build your own libdbusmenu-qt first. Apply this patch to make it build with ECM and Qt5: http://www.davidfaure.fr/2012/libdbusmenu-qt.diff
 
== Qt5-specific setup instructions ==
<pre>
export QT_MESSAGE_PATTERN='%{appname}(%{pid})/%{category} %{function}: %{message}'
</pre>
so that qDebug behaves almost like kDebug.
