Fix for Scigraph build error

Friday, September 3, 2004

The current McCLIM CVS sources of Scigraph generate a package lock error during compilation or loading with recent versions of CMUCL, I think the 19a prerelease and release series. It is caused by a conflict with the cl:variable symbol. The problem can be fixed by editing the file Apps/Scigraph/scigraph/package.lisp in the McCLIM source distribution. Change the form:

(eval-when (compile load eval)
  (defpackage GRAPH
    #-allegro (:nicknames gr)           ; "GR" names something already.
    #+allegro (:shadow variable)        ; shouldn't be inherited but is
    #+MCL     (:shadow copy)
    (:use dwim-lisp tool statistics)))

(eval-when (compile load eval)
  (defpackage GRAPH
    #-allegro (:nicknames gr)           ; "GR" names something already.
    (:shadow variable)                  ; shouldn't be inherited but is
    #+MCL     (:shadow copy)
    (:use dwim-lisp tool statistics)))
