This is version 3.5.13 of the Trinity Desktop Environment [TDE] 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 an alphabetical list:
ARTS (analog realtime synthesizer) is a environment of small modules
that one can plug together to process multimedia data. This directory
contains KDE wrapper and KDE user interface elements for ARTS.
The desktop communication program allows even shell scripts to
communicate with KDE applications. It's also the base for KParts.
kparts interface for text editors, mediaplayer and scripting.
OBSOLETE, see kabc: Used to be the address book library, but now only
used to convert kab-Addressbooks into kabc format.
The address book library.
KPart for 'kate', the KDE advanced text editor.
Personal certification manager.
Auto-Updater for config files.
This is the core collection of KDE stuff. Non GUI classes reside here.
The KDE daemon checks for newly installed software, update files
or hostname changes and takes according actions.
Library with pixmap effects.
The very versatile printing subsystem of KDE.
Library for password entering and handling
The main collection of misc. user interface classes (widgets).
KSpell and related classes are a frontend to ispell for use within a
For developers: KDE's custom widgets for Qt Designer.
Contains mostly stuff convert XML docbook files via XSLT into
human readable stuff.
The next generation HTML rendering widget designed for Konqueror. This
supports HTML 4, CSS, and a variety of other web related standards.
An all purpose extension to the qimgio class that supports various
Process launcher, used for fast KDE startup
Classes that fetch and decode URLs are contained here. This library also
contains "ksycoca", the system configure cache containing services,
applications, servicetypes and mimetypes.
I/O subprocesses to handle files, ftp, http, gzip and bzip2 streams.
KDE component model.
The theme engine lies within. It handles nearly anything relating to
customizing the appearance of widgets.
Client and backend to store values in encrypted files.
MIDI file handling and midi mapper (manages output of midi files to
Library for making KDE screensavers.
System independed dlopen() handler.
Contains texts of all used licenses.
Database of mime types.
Database of icons.
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
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.
If configure claims Qt cannot be found, look at http://www.trolltech.com
to get a copy of Qt, version 3.3.0 or newer. If you have peeked there
already, grab the SVN module qt-copy from anonsvn.kde.org, or a snapshot
thereof. Alternatively the svn module qt-copy from svn.kde.org can also be
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 3.0 installed, just copy all your .k*rc
files from $HOME to $HOME/.trinity/share/config. In the other case, default
values are used for most apps.
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
http://developer.kde.org/build/compilationfaq.html for known issues in certain OS
environments before reporting bugs or going mad :).
gcc 3.0/3.0.1 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 <will@FreeBSD.org> and Arun Sharma <firstname.lastname@example.org>
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 http://egcs.cygnus.com
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 avalanche of bug reports.
They spend hours figuring out which bug reports are valid and which aren't,
which bug reports are due to bugs or due to installation problems.
They can be of 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 distributor. 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 http://bugs.trinitydesktop.org 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. :-)
http://www.kde.org is a good starting point for info on KDE. If you are a
developer, you may also point your browser to http://developer.kde.org.
There is a plethora of mailing lists available, you can gain an overview
quickly by looking at http://lists.kde.org.
