TDEEDU

En/trinity_desktop_environment#Base_Packages

The tdeedu package includes some free programs developed by the KDE project for educational purposes. All programs are integrated in the Trinity Desktop Environment and translated in the project supported languages. All of the applications for students are grouped in four main categories:

• Languages: Some tools helpful to learn Yours or a foreign language.
• Mathematics: Some applications useful to learn algebra and geometry.
• Sciences: Offers a virtual planetarium and an element periodic table.
• Miscellaneous: Generic programs that cannot be included in any of the previously listed categories. An example is Ktouch a tool to learn typing.

The package is fully optional and no TDE functionality will go missing by not installing it.

Tdeedu and Slackware

The tdeedu package replaces kdeedu for KDE 3.5. The build system relies on autotools and has not been ported to cmake yet. The kdeedu build script can be used for tdeedu, but some updates and tweaks are due. The following rules were applied when compiling the package to ensure a clean build:

• 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 options were used for the configure command as the package seems not to need any. 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 \
     --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.
