KUniqueApplication complains ' Cannot find the D-Bus session server'

[Hui Jin]

Hi All,

Thanks for your generous help. I now could run kopete without problem.
I would like to share the experience with you. Sorry, I could not add
this post to the blog, since Blogger seems down today. I would add it
ASAP.

This HOWTO assume you have installed Qt4 and kdelibs4 before, and you
would like to upgrade it to the HEAD. The Qt4 is insalled in
/usr/local/Trolltech/Qt-4.1.3, and a symbol link is created in
/usr/qt/4; kdelibs is installed in /usr/local/KDE-4.0.

Let's start from the begining:
0. Read PORTING-TO-DBUS.txt in kdelibs4_snapshot
1. build dbus-0.62+
2. fetch kdesupport, build qt-dbus binding. I install it to
/usr/local/KDE-4.0, YMMV.
  cd ~/kdesupport; mkdir obj; cd obj;
  cmake -DCMAKE_INSTALL_PREFIX=/usr/local/KDE-4.0 -DCMAKE_BUILD_TYPE=debug ../
  make && sudo make install

3. Add this line to your .bashrc to make pkg-config happy:
export PKG_CONFIG_PATH=/usr/local/KDE-4.0/lib/pkgconfig:/usr/qt/4/lib
So you would not set it up later.

4. Build kdelibs
  cd kdelibs; mkdir obj; cd obj;
  source ~/.bashrc
  cmake -DCMAKE_INSTALL_PREFIX=/usr/local/KDE-4.0 -DCMAKE_BUILD_TYPE=debug ../
  make && sudo make install

5. Build kopete
  cd kdenetwork; mkdir obj; cd obj;
  cmake -DCMAKE_INSTALL_PREFIX=/usr/local/KDE-4.0 -DCMAKE_BUILD_TYPE=debug ../
  make && make install

I met some problems here:
the make just complains that dbus/qdbus.h is not found. Here is a
quick-and-dirty hack, add the hard-coded directory to the
CMakeList.txt : Ln 33

include_directories ( /usr/local/KDE-4.0/include/dbus-1.0
${QDBUS_INCLUDE_DIRS} ${CMAKE_SOURCE_DIR} ${CMAKE_BINARY_DIR}
${KDE4_INCLUDES})

6. start dbus
  $ dbus-launch --sh-syntax
It looks like the DBus environment is not corrected exported. So I
manually export the variables from the output:
export DBUS_SESSION_BUS_ADDRESS='unix:abstract=/tmp/dbus-29IavvsbXU,guid=fc11a244b8f599eb607605fa0b449100'
export DBUS_SESSION_BUS_PID=11244

7 start kopete
  $ kopete
Ok, kopete launches, but no account available here. I checked the
output, and found the version number confliction of
/var/tmp/kdecache-YOURNAME, just delete it and restart the kopete. It
works.

Thanks for your patience to go so far. :-)
