Look in the appropiate subdirectories or files to get more information
about the authors.
The package is maintained by Kalle Dalheimer <>, however
numerous people, too many to count, have contributed to kdelibs as a
whole. If you have a specific question, dig up the appropiate mailing
list address, and ask away.

About kdelibs
This is version 2.2 of the KDE libraries.
This package includes libraries that are central to the development and
execution of a KDE program, as well as internationalization files for these
libraries, misc HTML documentation, theme modules, and regression tests.
Here is a list:
* kdecore
This is the core collection of KDE stuff. Non GUI classes reside here.
* kdeui
The main collection of misc. user interface classes (widgets).
* kimgio
An all purpose extension to the qimgio class that supports some obscure
image formats.
* kfile
This library contains the KFileDialog in all its glory.
* kspell
KSpell and related classes are a frontend to ispell for use within a
GUI app.
* kab
The address book library.
* khtml
The next generation HTML rendering widget designed for Konqueror
(kfm's successor). This supports HTML 4, CSS, and a variety of other web
related standards.
* kio
Classes that fetch and decode URLs are contained here. This library also
contains "ksycoca", the system configure cache containing services,
applications, servicetypes and mimetypes.
* kjs
KDE's implementation of ECMAScript (aka JavaScript).
* kparts
KDE component model.
* kstyles
The theme engine lies within. It handles nearly anything relating to
customizing the appearance of widgets.
* dcop
The desktop communication program allows even shell scripts to communicate
with KDE applications. It's also the base for KParts.
* kssl
An SSL intergration for KDE. It currently uses OpenSSL.
* arts
ARTS (analog realtime synthesizer) is a environment of small modules
that one can plug together to process multimedia data.
* kdesu
Library for password entering and handling
* kinit
Process launcher, used for fast KDE startup
* ksgmltools
Docbook and SGML tools needed to generate documentation for KDE.
* libkmid
MIDI file handling and midi mapper (manages output of midi files to
various devices).
* interfaces
kparts interface for text editors
* libtldl
System independed dlopen() handler.
* mimetypes
Database of mime types.
* pics
Database of icons.
* libkscreensaver
Library for making KDE screensavers.
The libraries themselves have been covered (since Saturday, June 21st, 1997)
by the GNU Library General Public License (LGPL). Any other programs (such as
the examples) are covered by the GNU General Public License (GPL). All the
gory details for the LGPL reside in COPYING.LIB, and for the GPL reside in
Various parts are also covered under a BSD style license, detailed in
COPYING.BSD. Currently, code covered under such license is copyrighted by
Theo de Raadt.
When in doubt, check the individual file, they should all have license
headings and other identifying marks.
Common Mistakes
If configure claims Qt cannot be found, have a look at
to get a copy of Qt, version 2.2.3 or newer. If you have peeked there
already, grab the CVS module qt-copy from, or a snapshot
You can use --enable-debug with the configure script, if you want to have
debug code in your KDE libs. If you have the space and can stand code that's
somewhat slower, this is worth it. The extra information really
helps debugging and thus bugfixing.
On the other hand, --disable-debug removes all debug messages, leading
to a faster and cleaner desktop.
See also the file DEBUG.
If you have an kdebase older than 2.0 installed, just copy all your .k*rc
files from $HOME to $HOME/.kde/share/config. In the other case, default
values are used for most apps.
Compile Problems
Often, KDE compile failures are not KDE's faults but the one of the
compiler or the distribution used. For that reason, please have a look at for know issues in certain OS
environments before reporting bugs or going mad :).
gcc 3.0 is not yet able to compile all of KDE without errors, mostly due
to bugs in this version of the compiler. Some older version of gcc 2.96
also have problems compiling KDE due to compiler bugs. Even though
compilation may not report errors with these compiler, the usage of these
compilers may cause crashes when using the resulting executables.
If you are running a FreeBSD system, you will need to make sure that LIBS
is set to "-Wl,-export-dynamic". The easiest way to do this is to prefix
configure with it, i.e.: LIBS="-Wl,-export-dynamic" ./configure. Thanks to
Will Andrews <> and Arun Sharma <>
for identifying what needed to be done, and how to do it, and such.
If you get odd error such as:
as: Error: /var/tmp/ccK1Cfxa.s, line 2827: Truncating token:
and you're using egcs, try re-compiling all your C++ libs with -fsquangle,
and then recompiling whatever you were working on with -fsquangle. It
should help, and more information about this is available on the egcs FAQ
available at
How to report
Reporting bugs is an art. Why? Because bug reports can help and hinder.
They hinder if the developers are just buried in an avanche of bug reports.
They spend hours figuring out which bug reports are valid and which non,
which bug reports are due to bugs or due to installation problems.
They can be a tremendous help to notify developers on problems in areas that
they normally don't have access (e.g. KDE on AIX) to.
So, here are some tips on bug reporting:
* make sure your bug is due to KDE ... and not due to a packaging problem of
your Linux distrubutor. For example, most "I can not install the XYZ.rpm"
problem are due to packaging issues. Refer with such questions to your
Linux Distributor and his appropriate mailing list or bug reporting tool.
* The chance is high that your bug has already been dealt with ... so look
if there is a newer version of kdelibs available. Reporting bugs for
older, deprecated versions usually don't get that much attention :-)
* Also the chance is high that another one experienced your problem. The
bug report wizard at will help you to find out if your
problem has already been reported.
* The best bug report for a project based on voluntary work is of course one
that comes with a patch that solves the problem. :-)
