Support for other operating systems
Adium is only available on Mac OS X.
Adium is written with very Mac specific code—mostly, but not entirely, Cocoa. Porting it to another platform would require rewriting the entire application.
Read below which alternatives we suggest for each operating system.
Windows
Several multi-protocol
There are some skins available for Trillian and Miranda which modify them to look like Adium in some ways, such as this skin for Miranda.
Linux
Several multi-protocol
If you're using GTK+, we recommend Pidgin. Adium uses Pidgin's core (libpurple) for most protocols.
If you're using KDE, we recommend Kopete. Kopete even works with Adium message view styles.
But couldn't you use GNUStep?
We use Cocoa Bindings, Carbon, Quartz, Core Foundation, and Search Kit, among other
There was a GNUStep implementation very long ago, but it fell out of date and was missing features.
Mac OS 9
Look on MacUpdate to see if there are any clients that may work for you. Otherwise you may want to start looking at moving to OS X.
