A new committer from Sun has joined the Eclipse project and contributed source changes needed to support Solaris x86. As of 3.2RC4, Solaris x86 is an officially supported build. This was announced during a keynote address by Erick Gamma and John Wiegand. I'll have more on the keynote itself in a separate article.
According to Eclipse director Mike Milinkovich, this represents the first Sun committer on an Eclipse project, and also set a new record for the quickest turn-around from contribution to new platform supported. Sun will be in charge of doing the actual builds on their own servers, and sending them to appear on the eclipse.org web site. It is hoped that this kind of cooperation can be replicated to other platforms, opening up Eclipse to run on a much wider variety of machines.
Eclipse for Solaris x86 is available now from eclipse.org. Go to the downloads page, select "All versions", then "3.2RC4" (or later), and then the package for "Solaris (x86/GTK 2)". See bug 84344 for more information.
