KTORRENT

TDE - Applications

Ktorrent is a BitTorrent client for the Trinity Desktop Environment. It enables users to download files through the BitTorrent protocol, frequently used by Linux distributions to share ISO images of their install media. Ktorrent can download many files at once, configure bandwidth utilization limiting the whole client or specific torrents, manage a download queue, block or filter peers and much more. The program is features rich and can be further enhanced installing plug-ins. The release used in this paper is the TEDE compatible one. Ktorrent was successfully ported to KDE release 4: to use Ktorrent 4 specific features, please refer to the official home page.

Ktorrent and Slackware

A Ktorrent official package has been part of Slackware for many releases, usually included in the KDE release 3 or 4 directory. The official SlackBuild script was used as an example to write one suitable for the 3.5.13.2 release of TDE. The project rules and conventions were strictly 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.
• No specific option was issued through the configure command as no one seems needed.

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 to configure source code in accordance to the destination environment:

   # Configure the package
   LDFLAGS="${SLKLDFLAGS}" \
   CFLAGS="${SLKCFLAGS}" \
   CXXFLAGS="${SLKCFLAGS}" \
   ../${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 \
      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.
