The example works for me using SBCL which is weird as SBCL will usually kick up a fuss while CLISP will run almost anything thrown at it. I really need to add better error handling. But in any case, what seems to be happening is that the CFFI function that creates the SDL Window is not creating the SDL window. NIL or a NULL pointer is being returned to the function that is supposed to create a new SURFACE object. This function throws the error you are seeing. At least this is what I think is happening thanks to my wonderful error handling described earlier. Have you tried running any of the examples in the lispbuilder-sdl-examples package? If you can manage then please do and let us know if this same error is generated. I've been procrastinating when I should have been working off the numerous (501 and counting) SBCL notes and warnings generated by lispbuilder-sdl (CLISP reports no issues). I'm trying to clear up most of these which may hopefully shed more light on the problem you are experiencing. - Luke _______________________________________________ application-builder mailing list application-builder@lispniks.com http://www.lispniks.com/mailman/listinfo/application-builder
