Re: [Sbcl-help] SLIME, SBCL, saving and using images

[Jean-Philippe P. <hex...@gm...>]

There was a great post about that by Zach on some mailing list or
other some time ago but I couldn't find it so I'll paraphrase.

The easiest way to dump an image is to do the dumping before threads
even enter the picture at all.

So you make a load.lisp file containing the code to load everything
you need in the image, and the last thing this file does is invoke
SAVE-LISP-AND-DIE.

Then it's a simple matter of "sbcl --script load.lisp" and you have your image!
