'''TDE Multimedia''' provides developers with a set of common interfaces, libraries, tools and applications aiming to abstract the machine installed multi-media hardware and consent to write portable code. In TDE the goal is achieved recurring to [http://www.giustetti.net/wiki/index.php?title=En/TDE_arts aRts]: the '''Analog Real-Time Synthesizer'''. The aRts back-end daemon provides a portable sound server able to record and reproduce sound streams, several encoding and decoding libraries and a real time sound processing framework.

The tdemultimendia package replaces kdemultimendia for KDE 3.5. The build system relies on '''autotools''' and has not been ported to [http://www.cmake.org cmake] yet. The kdemultimendia build script can be used for tdemultimendia, but some updates and tweaks are due. To guarantee a smooth build the following guidelines were followed:

* The source code '''was patched''' in order to '''solve a version mismatch issue with libtool''': the source code was configured for release 2.2.6, but 2.4.2 is installed along Slackware 14.0.

Some configuration scripts required by the build procedure are missing from the source tarball. We create the makefiles using the make command:

Finally the script runs the '''./configure''' command with the proper option list. Package tdemultimedia requires '''--enable-closure''', '''--with-musicbrainz=no''' and '''--with-akode=no'''.

Once the configuration successfully concludes, the script runs the make command then goes on with packaging the software.
