[gambit-list] Error compiling macros

I did try adding each one of these: (load "~~lib/syntax-case") (load "~~/lib/syntax-case") (include "~~lib/syntax-case.scm") at the beginning of the file, but I keep getting:


*** ERROR IN "/home/octavio/test.scm"@5.17 -- Ill-formed expression


Where line 5 is:


(syntax-rules ()


I have no idea why this is happening, gambit supports macros and this macros is supposed to be legal. Don't know if it helps, but I'm using the code from this tutorial http://www.willdonnelly.net/blog/scheme-syntax-rules/

Thanks for your time!

Try manually loading the syntax-case library in test.scm before you use it.  With:

(load "~~/lib/syntax-case")

Hi all, I'm trying to compile a simple program using macros but for some reason it won't work.
This is the code in test.scm

    (define-syntax while
      (syntax-rules ()
        ((while condition body ...)
         (let loop ()
           (if condition
               (begin
                 body ...
                 (loop))
               #f)))))

    (define x 0)
    (while (< x 5)
      (set! x (+ x 1))
      (print x))

When I load the file into the interpreter (with the -:s option) it works, but when I try to compile it (using gambitc -:s -exe test.scm) I get the following error:
*** ERROR -- missing or invalid linking information for module "/usr/lib/gambit-c/_gambit"

I tried compiling with the interactive mode using
    (compile-file-to-target "test.scm")
    (quit)
    gambitc -exe test.c
and it compiles well, but when I try to run the exe I get:
    *** ERROR IN | test| -- Operator is not a PROCEDURE
    (#!unbound
     '#(syntax-object while ((top) #(ribcage #(while) #((top)) #(while))))
     '#<procedure #2>
     '*top*)

No matter how hard I try I can't compile any code that makes use of macros. Any help appreciated!
(I'm using Arch Linux and I installed gambit from Arch's repositroy, everything else apart from macros works well)
