Any advice or suggestions?
I strongly recommend calling cffi:load-foreign-library at run time only (never before delivery). That gives you control over how the library is loaded on startup (for example reporting errors to the user).
Thanks for your input. I guess that is a very sensible approach on all Lisps except Allegro which bundles the shared objects.
Luis, would you consider a patch to add a special variable *cffi-wrapper-delay-load* which would set a special mode for the generated wrapper.lisps?
This mode would inhibit the loading of generated shared objects and the definition of functions depending on them, so that the image can be saved. When the image is loaded then the definitions should be made at that time.
