With the current master branch of Gambit, given the files:
==> foo.scm <==
(define-macro (hello)
'(display "Hello world\n"))
==> foo.sld <==
(define-library (foo)
(export hello)
(import (scheme base) (gambit))
(include "foo.scm"))
The following error occurs:
$ gsi .
> (import (foo))
> (hello)
*** ERROR IN (stdin)@2.2 -- Unbound variable: foo#hello
Using ##define-macro instead of define-macro has the same effect, as do
`gsi -:r7rs .`, using (load "foo.scm") instead of (import (foo)), and
using the compiler instead of the interpreter. However, copy/pasting the
define-macro form into the REPL works fine. Exporting procedures
(instead of macros) works fine. What is the best current practice for
exporting macros?
