[Gcl-devel] load and package interaction

[Gabriel Dos Reis]

Camm --

  I came across a strange behaviour of GCL-2.6.8pre (CVS) that
I believe might be a GCL bug.  What follows is a reduction of
the issue.

Consider 3 files:

  * file f.lisp contains:

      (defpackage "FOO")

  * file g.lisp contains:

      (eval-when (eval load compile)
                 (load "f"))

      (defpackage "BAR"
        (:use "FOO"))

  * file h.lisp contains:

      (eval-when (eval load compile)
                 (load "g"))


Files f.lisp and g.lisp compile just fine.  However, compiling
g.lisp (after f.lisp and g.lisp) yields the mysterious failure:

address@hidden:~/tmp/gcl-bugs> gcl -batch -eval '(compile-file "h.lisp")'

Compiling h.lisp.

Error: "FOO" is not of type (LISP:OR LISP:SYMBOL LISP:STRING ...).
Fast links are on: do (si::use-fast-links nil) for debugging
Error signalled by LISP:USE-PACKAGE.
Backtrace: compiler::t1expr > system:error-set > lisp:eval > lisp:eval >

; (LOAD "g") is being compiled.
;;; The form (LOAD "g") was not evaluated successfully.
;;; You are recommended to compile again.
No FASL generated.



I see no problem with SBCL, CLISP, and ECL.
