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. -
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?
