HI to all...
I'm trying very hard to install phonon on my SLACKWARE PC. Im using Qt 4.6.1 (QtSDK 2010.1) on my Linux PC. I tried to execute phonon examples It is not getting compiled, Im getting error as Phonon NO SUCH DIRECTORY, class found etc. I came to know i want to install phonon Module, before that It needs back end support, In the phonon Doc they have G Streamer is required, I want to know which package should be installed for G Streamer, Initially i tried with G Streamer from site. It didn't get installed. Then i came to know liboil package should be installed , Then I installed liboil-0.3.16, glib-2.20.0,Then finally i tried with gstreamer-0.10.25. It got installed ,Then i tried to install Phonon in Qtsdk-2010.1/qt/

Qt Code: 
  1. ./configure -phonon
To copy to clipboard, switch view to plain text mode 
It went on for long time then I gave "gmake"... here i got full errors, I'm posting errors plz support me.I want to install phonon on My SLACKWARE PC.
