As it appears here that you are trying to export everything from that
module (in a somewhat incorrect formulation -- I can explain if you
like), and that seems to be a sort of pattern, I'd suggest that instead
we offer a module-export-all! function. Here is some code to provide
such a function for pre-2.0 guile:
(cond-expand
((not guile-2)
(define (module-export-all! mod)
(define (fresh-interface!)
(let ((iface (make-module)))
(set-module-name! iface (module-name mod))
;; for guile 2: (set-module-version! iface (module-version mod))
(set-module-kind! iface 'interface)
(set-module-public-interface! mod iface)
iface))
(let ((iface (or (module-public-interface mod)
(fresh-interface!))))
(set-module-obarray! iface (module-obarray mod))))))
Use that to export all bindings instead. As it is, there are some shims
for %module-public-interface hackery to keep on working if deprecated
code is compiled in, but you should migrate to calling
module-export-all!, I think.
Then your C code would unconditionally:
scm_call_1 (scm_variable_ref (module_export_all_var), mod);

Andy
