# Ready Lisp for OS X Leopard

Posted by John Wiegley on November 9, 2007 with labels: SBCL, SLIME

After upgrading my system to Leopard this weekend, I decided to refresh Ready Lisp as well. It now contains both 32-bit and 64-bit builds of SBCL (which has been bumped to 1.0.11), so if you have a Core 2 Duo machine, you’ll be running Lisp at full 64-bit! Alas, Emacs itself cannot support 64-bit as a Carbon app, because there are no 64-bit Carbon libraries. SLIME has also been updated, to CVS latest as of today. Aquamacs is still the same version at 1.2a.

I did spend several hours trying to build a fully Universal package that would run on PowerPC as well (I have a PowerBook G4 in addition to this MacBook Pro), but it seems Leopard has broken the PowerPC port of SBCL. Some of the core OS structures have changed, such as os_context_t.

Ready Lisp is now being versioned according to the SBCL version it contains, which makes today’s release ReadyLisp-1.0.11-10.5-x86.dmg. The older version, which still works on 10.4, can be downloaded here.

NOTE: The recent loading bug for Leopard users has been fixed. Please re-download. Also, it still does not work on OS X 10.4 (Tiger) at the moment. I will have to create a separate build of SBCL for that version this weekend.
