Can't quickload paiprolog in clisp #2

Open ksvanhorn opened 11 years ago

ksvanhorn commented 11 years ago

(ql:quickload "paiprolog") gets the following error:

\ - Continuable Error DEFUN/DEFMACRO(DEFMETHOD): # is locked.

The quickload maintainer says this is a problem with paiprolog itself.

Which implementation are you using? On SBCL 1.1.4 (ql:quickload "paiprolog") is successed.

As I said, I'm using CLISP 2.49. I have no problem on Clozure Common Lisp.

OK, I guess I didn't mention CLISP in the problem report. :-(

In any event, this may be a problem with CLISP, as the call (compile-file "foo.lisp") gives an error (cannot redefine setq), where the contents of foo.lisp are

--- begin foo.lisp --- (unless t (defmacro setq (a b) nil))

(setq var 'value) --- end foo.lisp ---

But I'm not certain that my understanding of the compilation process is correct, so my diagnosis may be wrong.
