从Ubuntu 12.04上的源代码构建的Qt 4.8.4无法正常工作

Question

I have tried for some time now to build Qt example systray . Everything works fine if I build it with Qt from official ubuntu repositoy.

Now I'm trying to build it using Qt 4.8.4 which is built from source. In this case, tray icons wont appear in system tray.

I have followed instructions on official Qt pages (requirements for X11 platforms, installation instructions), looked for possible solutions on qt web pages, ubuntu forums, stackoverflow, etc. but with no luck.

To compile and install Qt I made following steps: 1) installed suggested required packages 2) downloaded Qt 4.8.4 from offiacial web 3) configured with

./configure -release -nomake demos,examples,docs -no-webkit -no-script -no-scripttools -no-qt3support

4) installed with

make
sudo make install

5) added bin dir to PATH

Problem probably is not in built libs because if I copy them to another Ubuntu PC (not virtual machine) the example program works. I have only tried this with one non-virtual machine so I cant confirm if this may be the cause of problem.

I have tried this procedure on several virtual machines but with no luck. Am I missing something?

Ubuntu provides sni-qt package and patched Qt so you can use QSystemTrayIcon class from Qt with notification area in Unity (see http://bazaar.launchpad.net/~indicator-applet-developers/sni-qt/trunk.13.04/view/head:/README ).

You'll need to patch Qt source code before building it or use other desktop environment -- possibly you could just use other panel that provides classic tray area.
