I have received GINA, a user interface managment system for use with CLM (Motif) and CLOS. The README file for GINA says that it runs with Sun Common Lisp 3.0 and PCL but not with the CLOS provided in Sun Common Lisp 4.0. Has anyone ported GINA to Sun Common Lisp 4.0? Is there much involved? We will attempt to install GINA on Lucid 4.0 real soon but are prevented from doing so at the moment because of the EGC bug that was reported in the Lisp news group recently.

Michael Spenke, one of the developers of GINA, and I went back and forth with Lucid on this one. The reason is doesn't run with Lucid CL 4.0 is because of an AFTER method bug in Lucid Common Lisp. If you want to see if your Lucid CL has this bug, try out the following: (defclass label-1 () ((slot-1 :accessor slot-1 :initform 1))) (DEFMETHOD (SETF slot-1) :AFTER (NEW-value (X label-1)) (format t "hello-1~%")) (setq l1 (make-instance 'label-1)) (setf (slot-1 l1) 5) This works fine: whenever the last expression is called, the deamon prints out his message. But as soon as I define another class (defclass lab () ((slot-1 :accessor slot-1 :initform 1))) the deamon is not called anymore. That is, when you type (setf (slot-1 l1 5) "hello-1~%" isn't printed. If you have this bug, I suggest you get a new clos.sbin and a new Lucid binary. I got a new clos.sbin from Lucid and it fixed the AFTER method bug but then if I tried to recompile the old binaries there was a missing function! (Sorry, I don't recall which function and I don't have time to check). I suspect this new function is defined in a new Lucid binary so get a new Lucid binary too when you get a new clos.sbin. -- Scott Simpson TRW scott@coyote.trw.com

The proper procedure here is to get a coordinated set of patches from
Sun (I presume you are talking about Sun Common Lisp on the Sun4?)
I'm aware of several bugs in the base image that ought to be patched,
and likely one of them is needed before you apply the cited CLOS patch
(or, before using a clos.sbin repacked later than the original 4.0
