| | #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
| |
| | |
| === Qt 5 ===
| |
| | |
| To build qt5 execute:
| |
| $ git clone git://gitorious.org/qt/qt5.git --branch dev
| |
| $ cd qt5
| |
| $ git checkout dev
| |
| $ ./init-repository
| |
| $ mkdir build
| |
| $ cd build
| |
| $ ../configure -prefix $KF5 -opensource -confirm-license -nomake examples -qpa xcb -no-gtkstyle
| |
| $ make
| |
| $ make install
| |
| | |
| <b>NOTE for ArchLinux users</b>: qtwebkit uses python to generate some files, but it uses python2 syntax. So if you have installed python3, you'll get a compilation error on the file itab.py bevause print is no longer a statement, but a function. So, you would like to make /usr/bin/python to point to /usr/bin/python2. See also https://wiki.archlinux.org/index.php/Python
| |
| | |
| === Qt5-based dependencies ===
| |
| | |
| First, let's setup a "kde:" prefix for git commands. Add the following text to your ~/.gitconfig:
| |
| [url "git://anongit.kde.org/"]
| |
| insteadOf = kde:
| |
| | |
| pushInsteadOf = kde:
| |
| | |
| At this point you can continue building things by hand, or download http://www.davidfaure.fr/kde/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 phonon4qt5
| |
| $ mkdir phonon/build
| |
| $ cd phonon/build
| |
| $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_PREFIX_PATH=$KF5 ..
| |
| $ make
| |
| $ make install
| |
| | |
| Then build attica (branch master), and strigi (branch master, with submodules) and install them into the same prefix.
| |
| | |
| To build the patched libdbusmenu-qt execute:
| |
| $ bzr branch lp:libdbusmenu-qt
| |
| $ wget http://www.davidfaure.fr/2013/libdbusmenu-qt-fixup.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
| |
| | |
| = Build KDE frameworks =
| |
| Current state of KDE framework exist in frameworks branch of kdelibs.
| |
| | |
| Execute:
| |
| $ git clone kde:kdelibs --branch frameworks
| |
| $ mkdir kdelibs/build
| |
| $ cd kdelibs/build
| |
| $ cmake -DCMAKE_INSTALL_PREFIX=$KF5 -DCMAKE_PREFIX_PATH=$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>
| |
| | |
| To get more information out of qDebug statements (i.e. make it more like kDebug) :
| |
| <pre>
| |
| export QT_MESSAGE_PATTERN='%{appname}(%{pid})/%{category} %{function}: %{message}'
| |
| </pre>
| |
| | |
| Don't bother with KDEDIR and KDEHOME etc. this stuff isn't used anymore.
| |
| | |
| = Running unit tests =
| |
| 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 KDE4 application in this separate DBus session, it would conflict with your running KDE4 desktop.
