Re: Problem with modules in Guile 2.0

[Gubinelli Massimiliano <m.gubinelli@gmail.com>]

Thanks for the prompt reply to both of you. However the proposed solution do not work in my case. After implementing the begin-for-syntax alternative I now get

scheme@(guile-user)> (load "main.scm")
;;; compiling /Users/mgubi/t/build-64-guile-2.0/test-modules/main.scm
;;; note: source file /Users/mgubi/t/build-64-guile-2.0/test-modules/test-modules.scm
;;;       newer than compiled /Users/mgubi/.cache/guile/ccache/2.0-LE-8-2.0/Users/mgubi/t/build-64-guile-2.0/test-modules/test-modules.scm.go

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> 

if I understand correctly this backtrace it seems that the module is not completely loaded at compile time and there is not public interface available. How can I force the evaluation of the loaded modules in order to get a list of exported symbols?

Best
