| | #REDIRECT [[Get Involved/development]] |
| 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:
| |
| | |
| 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:$QT_PLUGIN_PATH
| |
| (lib64 instead of lib, on OpenSUSE)
| |
| </pre>
| |
| | |
| To use separate user settings for KF5:
| |
| <pre>
| |
| export XDG_DATA_HOME=$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 =
| |
| | |
| This is experimental and not the recommended way to contribute to KDE Frameworks at this point.
| |
| | |
| Make sure your Qt5 installation appears '''after''' your Qt4 installation in CMAKE_SYSTEM_PREFIX_PATH.
| |
| | |
| If you have Phonon for Qt4 installed, you must install Phonon 5 for Qt5 in a directory listed in CMAKE_SYSTEM_PREFIX_PATH '''after''' the directory containing Phonon for Qt4.
| |
| | |
| You will also have to build a patched libdbusmenu-qt with Qt5, and, like phonon, it must be installed in a directory listed in CMAKE_SYSTEM_PREFIX_PATH '''after''' the directory containing libdbusmenu-qt for Qt4.
| |
| | |
| The recommended way to do this is to install Qt5, Phonon 5, and the patched libdbusmenu-qt in your $KF5 directory, and pass -DCMAKE_SYSTEM_PREFIX_PATH=/usr:/usr/local:$KF5 to cmake when building KDE Frameworks.
| |
| | |
| 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
| |
| | |
| To build phonon execute:
| |
| $ git clone kde:phonon --branch five
| |
| $ mkdir phonon/build
| |
| $ cd phonon/build
| |
| $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_SYSTEM_PREFIX_PATH=/usr:/usr/local:$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=$KF5 -DCMAKE_SYSTEM_PREFIX_PATH=/usr:/usr/local:$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.
