View Full Version : How to use phonon on Ubuntu

19th May 2013, 22:50
I'm using Ubuntu 10.4 to compile my project. Since the installed Qt is 4.6, I reinstalled Qt 4.8. But when I try to compile my program, it gives me the error "cannot find 'phonon' no such file or directory".

The steps I did are:
1. Dowload "Qt libraries 4.8.4 for Linux/X11 (225 MB)" fromhttp://qt-project.org/downloads
2. Decompress the package and run "./configure" in the directory.
3. Run "make" and then run "sudo make install", Qt 4.8 is installed into "/usr/local/Trolltech". I checked the new installed "lib" folder but there's no "phonon" inside.
4. Use "sudo apt-get install libphonon-dev phonon-backend-gstreamer" to install the phonon libraries.
5. Going to my project, make sure the .pro file contains "QT += phonon" and compile the program.

The problem is when I use the 4.6 qamke (in /usr/share/) to compile, there's no phonon missing error.
But when I use 4.8, the error raises.

Thanks in advance.

You are obvioulsy missing some build dependencies for Phonon, so configure detects that it can't build Phonon and skips it.

Try installing the GStreamer development packages before running configure.

apt-get build-dep phonon-backend-gstreamer

might do the correct thing.
