This tutorial shows one way to get KDE from trunk running on Linux/BSD systems. Throughout the tutorial the bash shell is used. If you are interested in building KDE on other systems such as Solaris, MacOS or Microsoft Windows, please visit the Build page and see the links at the bottom for the respective operating systems.
Warning |
---|
Expect a higher risk of build failure on Mondays when critical changes are implemented. Dashboard reports unexpected breakages. You are encouraged to fix failing modules. |
The following must be installed first before you can successfully complete this tutorial:
You may also want to have the following installed:
In Kubuntu 7.04 (Feisty) the build dependencies you need are installed with:
sudo aptitude install build-essential cdbs debhelper cmake \
libxml2-dev libxslt1-dev libbz2-dev libclucene-dev librdf-dev \
shared-mime-info libgl1-mesa-dev libglu1-mesa-dev mesa-common-dev \
libxext-dev libjpeg-dev libpng-dev subversion libsm-dev libxinerama-dev \
libxrender-dev libfontconfig-dev libboost-dev libxcursor-dev doxygen \
libungif4-dev libdbus-1-dev
You can skip the manual installation of Qt 4.3, CMake 2.4.6 and DBus by installing the following packages (and their dependencies). Please Note: This will not work for Qt for KDE4 after Alpha 1 (Kubuntu feisty contains Qt4.3beta, not Qt4.3 final as required. Skip down to building Qt from svn below):
sudo aptitude install libqt4-dev-kdecopy libdbus-1-dev cmake
And for fully functional apidox frame work you also need:
sudo aptitude install graphviz
In openSUSE 10.2 and newer, you can install packages using Zypper:
sudo zypper install <package-name>
In older releases of SUSE, you can use YaST:
su
yast -i <packagename>
Required Packages
The packages you will need to install are:
xorg-x11-devel
libxml2-devel
kdesdk3
clucene-core-devel
boost-devel
libjpeg-devel
liblrdf-devel
libpng-devel
libxslt-devel
redland-devel
Mesa-devel
giflib-devel
subversion
gcc
gcc-c++
Optional Packages
You can skip the manual installation of Qt 4.3, CMake 2.4.6 and DBus by installing the adding the openSUSE Build Service KDE4 Repository to your installation sources.
For openSUSE 10.2 and newer do:
sudo zypper service-add http://software.opensuse.org/download/KDE:/KDE4/openSUSE_10.2 KDE4-102
For older versions of SUSE Linux do:
su
installation_sources -a http://software.opensuse.org/download/KDE:/KDE4/[YOUR SUSE LINUX VERSION]
Now install the following packages (and their dependencies):
cmake
dbus-1-devel
libqt4-devel
And for fully functional apidox frame work you also need:
graphviz
CMake binary packages for openSUSE are available from openSUSE build service.
You can use most stable ebuilds just remember to sync your portage before you begin.
We need to be unmasked and/or kept at a lower version to continue.
These are the packages you will need to install, some may already be installed so you may skip those by adding the update flag to emerge.
$ emerge -avu ebuild/name
sys-devel/gcc dev-util/subversion dev-util/pkgconfig x11-base/xorg-x11 media-libs/glut media-libs/mesa media-libs/jpeg media-libs/libpng media-libs/giflib dev-cpp/clucene dev-util/cppunit media-libs/liblrdf dev-libs/libxml2 dev-libs/libxslt x11-misc/shared-mime-info kde-base/kdesdk-scripts dev-libs/boost x11-libs/qt dev-util/cmake sys-apps/dbus dev-libs/redland
You will start compiling by hand from the Strigi section.
Good Luck!
Note |
---|
Some people like to have a separate user account for KDE 4 (for instance an old bug deleted files by mistake), and the instructions below were written with that approach.
However it is much more efficient to do everything with a single user account, see Increased Productivity in KDE4 with Scripts for more details. You can still follow the instructions below, but don't put the environment variables in your .bashrc, put them in a separate file that you source to switch to the KDE 4 environment. |
useradd -m kde-devel
passwd kde-devel
Instead of using the commands above, you can also use the User module in the KDE Control Center if you already have KDE3 installed.
Copy the ~/.bashrc from your normal user account to the new kde-devel account. Next, copy and paste the contents of the example .bashrc into ~kde-devel/.bashrc. Be sure to comment out the line alias make=makeobj if you do not have the makeobj command available. You will probably also want to modify the path to make sure it doesn't include your kde3 paths. To make it run, you have to open a new bash or to execute
source ~/.bashrc
This will provide access to commands such as cmakekde that are used in this tutorial as well as ensure that the proper paths are in place for Qt, KDE and CMake binaries.
For more information, please read the Getting Started/Increased Productivity in KDE4 with Scripts tutorial.
Switch to the user kde-devel: (don't forget the dash)
su - kde-devel
The rest of this tutorial assumes you are running as the kde-devel user.
On some systems a new user is configured by default to use /bin/sh. If this is not the case on your system, you can skip this section. Using /bin/sh can be very inconvenient to work with and you may want to change it to /bin/bash or another shell.
If you don't have root privileges and your system supports the changing of your own shell with the chsh application, then you could try to change your shell to /bin/bash by using:
chsh -s /bin/bash kde-devel
If your system comes with the usermod application you can run the following command as root: usermod -s /bin/bash.
Another option is to use the vipw application as root to safely edit your /etc/passwd. Locate 'kde-devel' in the the file. Change '/bin/sh' at the end of the line to read '/bin/bash', save your changes and exit.
The new shell will be started automatically when you log in as the kde-devel user again.
QtDBus and KDE are known to work with D-Bus versions 0.62, as well as 0.92 and upwards. Versions 0.60 and 0.61 may work too but are not tested. Versions 0.90 and 0.91 are known not to work. We recommend using post-1.0 release versions (at least 0.94), so consider upgrading if you haven't done so.
You may skip this section if you have a recent D-Bus version or if you don't want to upgrade.
Before running these steps in the recipe, make sure your X11 headers and libraries are available. The configure script run on line 5 should output:
Building X11 code: yes
Tip |
---|
Make sure you did set up your environment correctly as described above. This is necessary for the cs and cb functions to work. |
cs # 'cs' is a bash function, click here to learn more wget http://dbus.freedesktop.org/releases/dbus/dbus-1.0.2.tar.gz tar -xvzf dbus-1.0.2.tar.gz cd dbus-1.0.2/ ./configure --prefix=$DBUSDIR --localstatedir=/var make make install dbus-uuidgen --ensure
After changing into the source directory (line 1), D-Bus source code is downloaded from freedesktop.org (line 2) and unpacked (line 3). After going into the newly created D-Bus directory (line 4), the build is set up using the supplied configure script (line 5). After building (line 6) and installing (line 7) D-Bus, we use the dbus-uuidgen tool to install a machine identification file that allows the bus to start automatically when the desktop session starts (line 8).
Note that you need write access to /var for the last two steps. If your system does not have the sudo command, you can use the su command instead, e.g. su -c "make install".
If you get the error makeobj: command not found you are lacking the command makeobj.
Skip this if you have CMake >=2.4.5 installed. You should be able to directly use the binary packages available on the CMake site. There are also distribution specific packages available.
cs # 'cs' is a bash function, click Here to learn more wget http://www.cmake.org/files/v2.4/cmake-2.4.6.tar.gz tar -zxf cmake-2.4.6.tar.gz mkdir cmake-build cd cmake-build ../cmake-2.4.6/bootstrap make sudo make install
First, we go back to the kde-devel user's source directory (line 1), get the CMake sources (line 2) and unpack them (line 3). We create a directory to build CMake in (line 4) and go into it (line 5). We then run the CMake bootstrap script to set up the CMake build (line 6), then make (line 7) and install it (line 8) using the root user.
If your system does not have the sudo command, you can instead do su -c "make install".
Next we need to get the Qt4 that is in KDE's source repository. KDE is guaranteed to build against any Qt 4.3. Qt 4.2 and earlier are not supported and will not work. Qt 4.3 has been released only recently, so your distribution probably doesn't have packages for it yet (known exceptions: Kubuntu(feisty:Qt4.3 beta), openSUSE, Fedora, Gentoo, Debian experimental). You should use the copy in the KDE Subversion servers.
cd svn checkout svn://anonsvn.kde.org/home/kde/trunk/qt-copy cd qt-copy ./apply_patches ./configure -qt-gif -no-exceptions -debug -fast \ -prefix $QTDIR -qdbus -pch -nomake examples \ -nomake demos make -j2
# do copy files if the target doesnt match current dir, # clear obj files to save disk space otherwise if [ $QTDIR = `pwd` ]; then \ find . -name '*.o' -exec rm {} \; ; \ else make install; fi;
We switch back to the kde-devel user's home directory (line 1) and download the source code using subversion (svn) from KDE's repository (line 2). After changing into the resulting qt-copy directory (line 3), we run a script that manages the patches that come with qt-copy (line 4).
Once the patches have been applied, we then set up the build using the configure script (line 5-7). The various command line options used are explained in the qt-copy/README.qt-copy file. Finally, we build the minimal requirements for KDE (line 8) and install (line 9-10) Qt. If you want all the example and demo applications, you can either build them individually or simply do a make from the qt-copy directory.
Note that the installation does not require root as it installs Qt locally into $QTDIR. Anyway, installation is only needed if $QTDIR differs from $HOME/qt-copy, which is not the case if you have exactly followed the instructions.
If you get "error: X11/Xlib.h: No such file or directory", install the devel package of xorg (the actual name may vary between operating systems, for example it is xorg-dev on Ubuntu based systems such as Kubuntu).
If you get an error in the configure step about missing defines, check the value of $QMAKESPEC. Some distributions set this to point directly to the system-installed Qt. If unset QMAKESPEC solves the problem, you probably want to add it to the ~/.bashrc script.
If you get an error ".pch/debug-shared/QtCore", this is because Qt-4.3 enables precompiled headers if your gcc supports it, but for some reason it doesn't work for you. If you use distcc, configure qt with -no-pch. If you use icecream, update to the latest icecream from svn trunk.
Try running any Qt program, like assistant. Note: You may need to run xhost +local:kde-devel as your regular kde3 user to run this application. If it crashes in QSpanData::adjustSpanMethods, then your problem is the oxygen style. Try removing lib/kde4/plugins/styles/kstyle-oxygen.so and lib/kde4/plugins/styles/oxygen.so if they exist in the KDE install prefix.

If you have jumped to this section without reading Setting Up The Environment, the recipes provided will not work. The recipes are not in error; cs and cb are not typos. Your environment needs to be set up correctly for these instructions to work for you. |
There are several libraries that KDE applications rely on in the kdesupport module. This includes Strigi and Soprano for file metadata and search, eigen for visual effects in applications such as Kalzium, taglib for music players and qca for some cryptographic needs.
Strigi itself has a few dependencies as well: you will need the libraries and headers for libz, libbz2, openssl (libcrypto or libssl), libclucene (=0.9.16; version 0.9.17 does not work), and either libxml2 or libexpat.
cs # cs is not a typo svn checkout svn://anonsvn.kde.org/home/kde/trunk/kdesupport/ cd kdesupport cmakekde
We change to the base source directory (line 1). We download the sources in kdesupport using subversion (line 2), go into the new ~/src/kdesupport directory (line 3), and commence the build (line 4). This will leave us in the kdesupport build directory after the build is completed.
If you get
CMake Error: This project requires some variables to be set, and cmake can not find them. Please set the following variables: LIBXML2_INCLUDE_DIR (ADVANCED)
you should install the development package for libxml2.
If you get
CMake Error: Could NOT find REDLAND
then you need librdf from the Redland. If your distribution does not provide the librdf package, you can download the source there: http://download.librdf.org/source/ and build it. (Gentoo users: The ebuild for librdf is named dev-libs/redland)
With Qt4, Strigi, and Soprano built, we can now move on to building KDE's base libraries. If you use the aforementioned .bashrc this is where those new functions come in handy.
cd $KDE_SRC mkdir KDE && cd KDE svn checkout svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs cd kdelibs cmakekde
We change to the base source directory (line 1) then make and go into the KDE directory (line 2). We download the sources for kdelibs using subversion (line 3), go into the new ~/src/KDE/kdelibs directory (line 4), and commence the build (line 5). This will leave us in the kdelibs build directory after the build is completed.
Tip |
---|
There might be missing dependencies on your system! They are easily overlooked in the output of cmakekde. You might want to do a cmake $KDE_SRC/KDE/MODULE_NAME prior to compiling any kde modules (like kdelibs, kdepimlibs etc.) |
There are additional CMake modules in kdelibs/cmake/modules/ that are necessary for building KDE4 applications. These will be installed for you when kdelibs itself is installed.
If you have problems compiling kdelibs, first make sure the software in the Required Software section above is installed and works. Other possible hints include:
If cmakekde still gives the same error then try this
cd cmake -DCMAKE_INSTALL_PREFIX=$KDEDIR \ -DCMAKE_BUILD_TYPE=debugfull \ -DKDE4_BUILD_TESTS=ON \ ~/src/KDE/kdelibs make make install
CMake Error: KDE Requires Qt to be built with SSL support
, install openssl-devel, and re-compile QT.
kdelibs/kimgio/ico.cpp:188: undefined reference to `QImage::jumpTable()'
it means you compiled QT without QT3 support(no, linking to a true QT3 install won't work)After kdelibs, but before kdebase, you need to build and install kdepimlibs.
cs KDE # cs is not a typo svn checkout svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepimlibs cd kdepimlibs cmakekde
We go into the KDE source directory (line 1), download the source code for kdepimlibs using subversion (line 2) and then go into the new ~/src/KDE/kdepimlibs directory (line 3). We then commence the build (line 4). This will leave us in the kdepimlibs build directory after the build is completed.
You may need kdebase for some kioslaves.
cs KDE # cs is not a typo svn checkout svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase cd kdebase cmakekde
If you have troubles compiling kdebase:
Although the API documentation for KDE is available online at api.kde.org, it is sometimes useful to have it on your own disk, for example when you want to use KDevelop for browsing the documentation or when you are not able to be online all the time.
Be aware that generating the API documentation can take several hours and takes almost half a gigabyte of diskspace. The generation is handled by a script in kdelibs/doc/api, you need doxygen to be able to run it.
To build the API documentation for kdelibs, type the following:
cs KDE/kdelibs # cs is not a typo $KDE_SRC/KDE/kdelibs/doc/api/doxygen.sh \ --doxdatadir=$KDE_SRC/KDE/kdelibs/doc/common .
Repeat for other modules as desired.
cd <module home> $KDE_SRC/KDE/kdelibs/doc/api/doxygen.sh \ --doxdatadir=$KDE_SRC/KDE/kdelibs/doc/common .
What can happen over time, after some svn up commands, is that some of the tools used in the KDE build chain change their output format. For example, kcfg files are read by kconfig_compiler to produce configuration dialogs. CMake cannot detect those changes, and the compilation might fail. A workaround is to always force a re-generation of all such files:
find $KDE_SRC/kde/kdebase -name "*.kcfg" | xargs touch
The same applies to ui files as produced by Qt designer.
You are now ready to start building other svn modules in the same fashion as you built kdebase, running and testing KDE4 or writing your own patches and applications.
See the Set up KDE 4 for development tutorial for how to start KDE 4 applications and how to use KDevelop to work on them.
