How to deploy a phonon based application on ubuntu OS?



  • Dears,
    I have writed an application using phonon to play back and can work well under my developing system(ubuntu 10.04). When I deploy it to another machine without installing the Qt library, errors occur. I follow the steps described in Qt document about 'Deloping Qt application on X11 platforms',here the linking site:http://doc.qt.nokia.com/latest/deployment-x11.html .
    Following are the files I begin to deploy:

    • musicPlay
    • musicPlay.sh(bq. the same contents as the plugandpaint.sh)
    • libphonon.so.4
    • libQtCore.so.4
    • libQtGui.so.4
    • libQtXml.so.4
    • libtag.so.1(bq. for using TagLib)
    • libQtDBus.so.4
    • libgstreamer-0.10.so
    • libaudio.so.2
    • phonon_backend/ (bq. including phonon_gstreamer.so,phonon_xine.so)

    Just want to work well ,the files may be more than what I really need.

    First, I run musicPlay.sh in my current system and it can work. then,I copy the files to another machine(the same OS but not installing Qt) and do it again,somethings unexpected happen:
    @WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded
    Segmentation fault
    @
    It seems to mean that I have missed the phonon backend plugin,but I have alreadly created the phonon_backend directory and put the plugins inside it.
    I hope someone may give me a suggestion, Thank you.



  • If you're using GStreamer you also need to ship GStreamer plugins, but you should really check its documentation to see how...



  • Thanks the reply.Yes,I use the default GStreamer as backend.I read the 'phonon' documentation and know that the libgstreamer-plugins-base0.10-0 should be required.But there is another question.This package is automatically installed through 'apt-get install' command on ubuntu,and I don't know where it is located.If any commands can help to search the package?
