[cl-unification-devel] Problems compiling code use #T template
by John Leuner 20 Jul '06

20 Jul '06

When I compile the following code in SBCL (using C-c C-k in Slime), (in-package :cl-user) (defun check-recipient () (unify:unify #T(list ?a ?b ?c) '(1 2 3))) I get this error report: ; file: /home/jbominji/jbominji/extra.lisp ; in: DEFUN CHECK-RECIPIENT ; (CL.EXT.DACF.UNIFICATION:UNIFY #T(LIST ?A ?B ?C) '(1 2 3)) ; ==> ; #T(LIST ?A ?B ?C) ; ; caught ERROR: ; don't know how to dump #T(LIST ?A ?B ?C) (default MAKE-LOAD-FORM method called). ; ; note: The first argument never returns a value. ; '(1 2 3) ; ; note: deleting unreachable code ; ; compilation unit finished ; caught 1 ERROR condition ; printed 2 notes ; /home/jbominji/jbominji/extra.fasl written ; compilation finished in 0:00:00 STYLE-WARNING: redefining CHECK-RECIPIENT in DEFUN This code works when the compiler does not have to write a fasl file. What should I be doing to allow make-load-form to succeed? Thanks John Leuner

[cl-unification-devel] Re: cl-unification library fails

Hi John I saw your message today on the CL-UNIFICATION mailing list and I answered there. As I said, it looks to me a problem with Slime + Reader Macros. The #T(...) reader macro expands into a template instance. Maybe that is the problem.
