FFI Troubleshooting
Last updated at 6:26 pm UTC on 14 March 2007
There are a number of errors you can get while using FFI and no clear documentation of what they mean. As you figure out what the message means and the kinds of things that need to be examined to fix it, please document it here:

Error: Callout mechanism not available
Means that Squeak can't find the SqueakFFIPrims plugin. Check to see if it's in the same directory as the rest of the plugins, or in the same directory as the image and that it's permissions readable/executable. There have been known occasions where even if the file is there this message can occur. Sometimes replacing the plugin file will help. (http://bugs.squeak.org/view.php?id=376)
