Introduction
This page details the build requirements for Qt and some related packages. For most of these requirements it is preferable to use your distribution supplied packages, however in some case you will need to build some requirements yourself and this page will also explain how to do so.
Required Steps
You need to have completed the following steps:
- Set up your [[../Environment|Build Environment]]
- Selected your [[../Recipes|Build Recipes]]
- Installed the [[../Requirements|System Requirements]]
- Understand the [[../Requirements#Definitions|Requirements Table format]]
makeobj
Makeobj is a shell script to assist make.
| Requirement | Stable Requires | Unstable Requires | Devel Pkgs? | Details |
|---|---|---|---|---|
| makeobj | r1215872 | r1215872 | No | A make helper shell script |
It is a part of the kdesdk module and, while optional, is strongly recommended when building KDE modules. If you have kdesdk installed on your system then this version should be sufficient, but r1215872 is recommended when working with Git.
To install it download via WebSVN and install into your path somewhere, preferably ~/.bin. Once you have built kdesdk from source you should then remove this copy.
Qt
Qt is the development freamework that all KDE Software is built upon.
| Requirement | Stable Requires | Unstable Requires | Devel Pkgs? | Details |
|---|---|---|---|---|
| Qt | >= 4.7.0 | >= 4.7.0 | Yes | The Qt development framework |
Most distributions package a recent enough Qt to build KDE, although you may need to add an extra repository to do so. Building Qt can take a long time, so packages are preferred for a quick start.
At some stage, KDE master may switch to relying on a development version of Qt, or may require patches to Qt for bug-fixes that have not yet been released by Qt. In this case you may need to build your own copy of Qt to build KDE against. You can choose use either the main Qt repository on Gitorious or the KDE copy of Qt. You can choose to overwrite your system Qt install when doing so but this is not recommended. You are advised to set your build environment $QTDIR install directory to a local folder different to $KDEDIR to allow easy switching between Qt versions.
Please see the KDE Qt project page for further details. It is recommended to read the INSTALL file for more details.
Note that you need to install Qt and Phonon from Qt and then later to install Phonon KDE from git at the same location. This will ensure you get sound in Qt-based applications as well as in KDE ones.
Easy Recipe
Ensure you setup your environment $QTDIR to point to somewhere suitable, e.g. /usr/local.
cd <your source directory> git clone kde:qt cd qt ./configure <configure options, use $QTDIR as your 'installdir'> nice make -j2 # for faster compiles use -j(X+1)' where X is your number of processor cores make install
Full Recipe
cd <your source directory> git clone git://anongit.kde.org/qt cd qt ./configure <configure options> nice make -j2 # for faster compiles use -j(X+1)' where X is your number of processor cores make install
Troubleshooting
If ./configure produces errors about missing headers, run the following command before trying again:
QTDIR=`pwd` bin/syncqt
Make sure which qmake delivers something out of $QTDIR, e.g. /home/kde-devel/qt-kde/bin/qmake
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.
Generating local API documentation
It's nice to have the Qt documentation locally for nice integration with KDevelop, and doing this is really quite easy:
cd $KDE_SRC/qt make docs ./config.status make install
Note that it is necessary to do this only once, even if you rebuild Qt later.
DBusMenu-Qt
DBusMenu-Qt is a library providing a Qt implementation of the DBusMenu spec.
| Requirement | Stable Requires | Unstable Requires | Devel Pkgs? | Details |
|---|---|---|---|---|
| DBusMenu-Qt | Yes | A Qt implementation of the DBusMenu spec. |
Your distribution packages should be sufficient for this requirement. If you need to build your own copy using the Easy or Full Recipe then ... \n
The Business 9 Women Kept A Secret For Three Decades
Somewhere in West Tennessee, not far from Graceland, nine women -- or "The 9 Nanas," as they prefer to be called -- gather in the darkness of night. At 4am they begin their daily routine -- a ritual that no one, not even their husbands, knew about for 30 years. They have one mission and one mission only: to create happiness. And it all begins with baked goods.One of us starts sifting the flour and another washing the eggs,

The World Waits For You
Its so easy to give up on our dreams; its so easy to do what everybody expects us to be doing; its so easy to blend in, to be like everybody else, just another person in the crowd, having nothing interested to say, nothing interesting to show, nothing interesting to share with the world. Its so easy to stay in our comfort zone, away from our doubts, fears and worries; away from change and all that is unfamiliar; away from growth and evolution; away from all the opportunities life has to offer us; away from all that is beautiful, empowering and great away from life.
