I've previously mentioned that SWT-based Java apps need some work to run on Intel Macs. This is still true if you're building against Eclipse 3.1.

Fortunately, it's dead simple - all you need to do is download the Universal Eclipse 3.1.2 (available as an attachment to Bug 98889) and copy some of its files into your app.

First, you need the JAR containing the architecture-specific SWT jnilib. Assuming Eclipse is unpacked into /Applications/Eclipse, and you're in your app's .app folder:

If you're building an RCP-based app, you should update the Eclipse launcher, too -- otherwise Rosetta will drag along and you'll have a several second delay when starting your app. Thanks to the simplicity of the launcher - which determines class loading based on the name it's called by - you can just copy the Univeral Eclipse launcher onto your app's launcher. Assuming you're in your .app folder, and your app is called MyRCPApp:

There it is -- zip this up and you've got a Universal app. (Or better yet, update your 3.1.2 delta pack so your build process does this automatically) and you've got a Universal build.

(Sorry if this seems elementary or obvious -- I was feeling bad about not having updated my blog recently, and I thought an easy entry would kickstart me into writing more!)
