D-Bus is a software library used for easy inter process communication and message handling. D-Bus was adopted by many modern desktop environments such as GNOME or KDE to allow applications to talk to one another. The dbus-tqt package contains libraries integrating D-Bus to QT3 and, together with its twin dbus-1-tqt, is a prerequisite for building and running the Trinity Desktop Environment. More information about D-Bus can be found at the web site of project freedesktop which coordinates software development and documentation management.
D-Bus-Tqt and Slackware
There is no dbus-tqt equivalent among the Slackware 13.0 KDE 3 packages. A build script was written using the TDE documentation and the out of support TDE build kit for Slackware as reference. All packages listed in the prerequisite category were ported from autotools to cmake and dbus-tqt is no exception. Cmake is used to configure and execute a full build from source code. In accordance to other packages configuration, /opt/trinity was used ad root directory for dbus-tqt. Cmake was configured to use standard TDE build options as no special requirement emerged from the documentation. Some of the main script lines and related comments will follow.
The build script must clean the cmake cache:
# Clean cmake cache
find . -name CMakeCache.txt -exec rm {} \;
Then create a new directory where to build source code and save output binary files. As for previously built packages the directory was named build in order for cmake to find it:
# Create a directory where to build source (cmake wants the name to be build).
cd ${TMP}/tmp-${PRGNAM}
mkdir build
cd build
The build script specifically sets Qt libraries path in order for build 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
And eventually runs the cmake command with standard options as suggested in the official documentation:
cmake ${TMP}/tmp-${PRGNAM}/${PRGNAM}-${VERSION} \1
-DCMAKE_C_FLAGS:STRING="${SLKCFLAGS}" \
-DCMAKE_CXX_FLAGS:STRING="${SLKCFLAGS}" \
-DCMAKE_INSTALL_PREFIX=${PREFIX} \
-DSYSCONF_INSTALL_DIR="/etc/trinity" \
-DLIB_SUFFIX=${LIBDIRSUFFIX} \
-DQT_VERSION=3 \
-DQT_INCLUDE_DIR=/opt/trinity/include \
2>&1 | tee ${OUTPUT}/${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 by mean of command installpkg as usual in Slackware Linux.
