There is a new version of Ready Lisp for Mac OS X available. This version is based on SBCL 1.0.16, and requires OS X Leopard 10.5. The most notable change from the previous version is that 64-bit mode and experimental threading are no longer supported, since both have been known to have issues on OS X, while the purpose of Ready Lisp is to smoothly introduce Common Lisp to new users.

A couple of pathname issues were discovered in the release of Ready Lisp that was posted yesterday, leading to the inability to load asdf-install (or use it). These have been fixed in the new release uploaded today. If you now use asdf-install and choose a “system-wide” installation, the installed packages get saved in your Application bundle. However, due to the way that asdf-install itself works, if you then move your application bundle to another directory, symbolic links in the systems directory will get broken. So I recommend installing new packages into your home directory instead.

Also, the sources for SBCL are now included, meaning that if you use M-. (jump to definition) and pick a function like mapcar, it will drop you into the source code for SBCL’s mapcar implementation.

The new version is available here (the old link still works, it is now a reference to that one).

Lastly, I’ve created a new home page for the Ready Lisp project, which now lives here.

There is a new version of Ready Lisp for Mac OS X available. This version is based on SBCL 1.0.12.17, and requires OS X Leopard 10.5. The most notable change from the previous version is that it is now fully universal, supporting PowerPC and 32- bit and 64-bit Intel machines. Also, threading has been turned on for Intel processor. See the NEWS below.

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.
