'''A'''nalog '''R'''eal '''T'''ime '''S'''ynthesizer è una libreria audio utilizzata in KDE 2, KDE 3 ed in TDE avente lo scopo di simulare un sintetizzatore analogico utilizzato dall'ambiente grafico e dalle sue applicazioni. La libreria fornisce '''un sound server integrato''', il software '''artsd''', avente il compito di mixare diversi flussi sonori in tempo reale. Nelle distribuzioni Linux recenti la funziona di mixer è stata passata ad [http://www.alsa-project.org/main/index.php/Main_Page '''ALSA'''] il sottosistema sonoro del kernel Linux. La libreria ARts '''non è più attivamente supportata dal 2004''' ed è stata sostituita dalla nuova '''API Phonon''' in KDE 4.
'''A'''nalog '''R'''eal '''T'''ime '''S'''ynthesizer is a multimedia library used by KDE 2, KDE 3 and TDE whose main goal consists of simulating an analog synthesizer used by the desktop environments and their many applications. '''An integrated sound server''', the '''artsd''' daemon, is part of the library and is used to merge distinct sound streams in real time. In later Linux distributions the mixer function shifted to [http://www.alsa-project.org/main/index.php/Main_Page '''ALSA'''] the Linux kernel sound subsystem. ARts '''is no longer in active development and hasn't been since 2004''' when it was replaced by '''the Phonon API''' in KDE 4.

ARts is part of the prerequisite packages for TDE. Its build scripts '''were ported to [http://www.cmake.org cmake]''' therefore the '''autotools''' build suite is no longer needed to configure and compile the source code. A build script was written based on the official ''' Slackware 13.0 slackbuild script for ARts''' with some updates to integrate cmake. The '''/opt/trinity''' directory was used as root directory for the package both to ensure a pacific coexistence with KDE 4 and to uniform ARts configuration to the other packages. The '''-DCMAKE_SKIP_RPATH="OFF"''' flag was imposed to the cmake command as suggested int the [http://www.trinitydesktop.org/wiki/bin/view/Developers/HowToBuild TDE build how-to]. The flag will allow ARTs to execute command during the build process.
The slackbuild script for the ARts package is part of the archive found at the following [http://www.giustetti.net/resource/slackbuild/tde/35132/arts.tar.gz link]. Some comments to the commands used through the script to ensure a smooth build follow.
First of all you need to '''clean the cmake cache'''. Task accomplished by lines:
<syntaxhighlight lang="bash">
# Clean cmake cache
# Clean cmake cache
find . -name CMakeCache.txt -exec rm {} \;
find . -name CMakeCache.txt -exec rm {} \;
</syntaxhighlight>
Then you must '''create a directory''' where to compile the source code and store output files. ''Cmake seems to have a preference for '''build''' as directory name. It won't work otherwise'':
<syntaxhighlight lang="bash">
# Create a directory where to build source (cmake wants the name to be build).
# Create a directory where to build source (cmake wants the name to be build).
cd ${TMP}/tmp-${PRGNAM}
cd ${TMP}/tmp-${PRGNAM}
mkdir build
mkdir build
cd build
cd build
</syntaxhighlight>
'''Qt library paths are needed''' for scripts to find binary files while building the source code:
<syntaxhighlight lang="bash">
# Add temporary paths to handle new libraries during build
# Add temporary paths to handle new libraries during build
export QTDIR=/opt/trinity
export QTDIR=/opt/trinity
export LD_LIBRARY_PATH=/usr/lib${LIBDIRSUFFIX}:/opt/trinity/lib${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:$PKG_CONFIG_PATH
export PKG_CONFIG_PATH=:/usr/lib${LIBDIRSUFFIX}/pkgconfig:/opt/trinity/lib${LIBDIRSUFFIX}/pkgconfig:$PKG_CONFIG_PATH
</syntaxhighlight>
Finally you can run cmake with the aforementioned option:
<syntaxhighlight lang="bash">
-DCMAKE_C_FLAGS:STRING="${SLKCFLAGS}" \
-DCMAKE_CXX_FLAGS:STRING="${SLKCFLAGS}" \
-DCMAKE_CXX_FLAGS:STRING="${SLKCFLAGS}" \
-DCMAKE_INSTALL_PREFIX=${PREFIX} \
-DCMAKE_INSTALL_PREFIX=${PREFIX} \
-DQT_INCLUDE_DIR=/opt/trinity/include \
-DQT_INCLUDE_DIR=/opt/trinity/include \
2>&1 | tee ${OUTPUT}/${PRGNAM}_configure.log
2>&1 | tee ${OUTPUT}/${PRGNAM}_configure.log
</syntaxhighlight>
And go on running the '''make''' command to build all then execute the packaging steps.
The outcome package can be installed recurring to the '''installpkg''' command as usual in Slackware linux.
