iTunes for Windows XP can be run on Fedora 9 using Wine, an Open Source implementation of the Windows API on top of X and OpenGL. Please note that iTunes runs a bit slow over Wine and I have yet to test an iPhone or iPod with this configuration.
First, install all the wine packages.
sudo yum install wine*
Now, install the pulseaudio alsa plugin for sound support
sudo yum install alsa-plugins-pulseaudio*
Now, install iTunes using wine
You can now run iTunes manually like so:
env WINEPREFIX="$HOME/.wine" wine "C:\Program Files\iTunes\iTunes.exe"
If you get an error regarding the registry, ignore it by clicking OK.
Here is a screenshot of iTunes running on Fedora 9. Note that there is an icon for iTunes in Gnome’s Notification Area (system tray).
