You are mistaken. GCL does have CLOS. It uses PCL. I recall even the ancient 2.4 version had CLOS, although I think PCL was an add-on at the time. Recent versions include pcl as part of the build---at least 2.6.8 does. Ray

Could you please tell me where I could download a version of the GNU Common LISP which does have CLOS (yes, in the form of PCL.) regards, Antti J. Ylikoski Helsinki, Finland, the E.U.

A few seconds with google produced http://ftp.gnu.org/gnu/gcl/binaries/stable/ which appear to be for Windows. But you can probably get binaries for common Linux distributions. ftp.gnu.org/pub/gnu/gcl appears to have sources for various versions. Ray

I wrote the following short CLOS test, and loading the file into the GCL ended with an error message, whereas with the Clozure CCL the file will load impeccably. ------------------------------ ;;; Test of CLOS. (defclass a () (zap)) (defclass b () (zup)) (defclass c () (zip)) (defclass alla (a b c) (zop)) (defmethod a-print ((x a)) (print 'foo-bar-baz)) ;;; With GNU Common LISP, exits with the error message ;;; "Error: The function DEFCLASS is undefined." ;;; ;;; With the Clozure Common Lisp Version 1.4-r13122 (WindowsX8664), ;;; the file loads with no difficulties. ;;; ;;; ------------------------------ One plausible explanation is that that version of GCL has the CLOS but it needs to be (LOAD ...) ed from somewhere. Portable CommonLOOPS was such a system. regards, Antti Ylikoski Helsinki, Finland, the E.U.

No, I'm not sure.

Or even (find-package "PCL"). I guess if the latter fails, that means the binaries don't have CLOS. I didn't do anything special when I built gcl, other than configuring with --enable-ansi. Ray |
