TDE - Base Packages

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 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.

To the final user the tdemultimedia package provides a set of tools and applications able to read and reproduce many sound or video file formats through easy to use graphical interfaces. Some common use included programs are:

  • artscontrol: A graphical interface for easy sound server configuring and monitoring.
  • juk: A virtual jukebox able to build and manage music collections.
  • kaboodle: A small and easy to use media player.
  • kaudiocreator: A CD ripper.
  • kmid: A midi file player.
  • kmix: The TDE integrated mixer.
  • krec: A sound recorder.
  • kscd: A music CD player.
  • noatun: A small, feature rich multimedia player.

Many of the listed programs functionalities can be enhanced recurring to plug-ins and optional expansion modules.

Tdemultimedia and Slackware

The tdemultimendia package replaces kdemultimendia for KDE 3.5. The build system relies on autotools and has not been ported to 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:

  • Directory /opt/trinity was set as package root directory.
  • Some missing makefiles were created running the make command from inside the main directory of the code extracted from the source archive.
  • 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 configure options specific to tdemultimedia were used: --with-musicbrainz=no and --with-akode=no.

Some script lines of code and related comments follow.

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

   # Prepare the package for building (Create the configure script).
   echo "(II) admin makefile run here" >> ${OUTPUT}/${PRGNAM}_configure.log
   make -f admin/Makefile.common \
      2>&1 | tee -a ${OUTPUT}/${PRGNAM}_configure.log

A patch is needed to solve a libtool package version mismatch conflict:

   # Patch the admin/ltmain.sh script in order to solve a version mismatch.
   patch -p0 -i ${SRCDIR}/ltmain_version_update.patch

The script specifically sets Qt libraries paths in order for other scripts to find them at build time:

   # Add temporary paths to handle new libraries during build
   export QTDIR=/opt/trinity
   export PATH=/opt/trinity/bin:/usr/bin:$PATH
   export LIBDIR=/usr/lib${LIBDIRSUFFIX}
   export LD_LIBRARY_PATH=/usr/lib${LIBDIRSUFFIX}:/opt/trinity/lib${LIBDIRSUFFIX}
   export PKG_CONFIG_PATH=:/usr/lib${LIBDIRSUFFIX}/pkgconfig:/opt/trinity/lib${LIBDIRSUFFIX}/pkgconfig:$PKG_CONFIG_PATH

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

   # Configure the package
   ../${PRGNAM}-${VERSION}/configure \
      --prefix=${PREFIX} \
      --sysconfdir="/etc/trinity" \
      --libdir=${LIBDIR} \
      --mandir=${PREFIX}/man \
      --with-qt-dir=${QTDIR} \
      --with-qt-includes=${PREFIX}/include \
      --with-qt-libraries=${PREFIX}/lib${LIBDIRSUFFIX} \
      --disable-rpath \
      --with-musicbrainz=no \
      --with-akode=no \
      --enable-closure \
      2>&1 | tee -a ${OUTPUT}/${PRGNAM}_configure.log

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

A full script can be downloaded from the following link. The output package can be installed using command installpkg as usual in Slackware Linux.
