lispbuilder-sdl and lispbuilder-sdl-ttf conditionally load different CFFI forms depending on the availability of a particular library. [...] Is there a mechanism in CFFI to enable this if define-foreign-library cannot be used?
If you really want it to signal an error, you could add a clause such as (t (:or)). E.g.: (define-foreign-library sdl-glue (:windows "lispbuilder-sdl-glue.dll") (t (:or))) In this case, I suppose you could also do something like: (defparameter *glue-loaded-p* #+windows t #-windows nil) Or, perhaps even better: (defparameter *glue-loaded-p* (foreign-library-loaded-p 'sdl-glue)) -- Luís Oliveira http://r42.eu/~luis/
