Subject: Re: [plt-scheme] foreign: am I missing something basic? - msg#00493List: plt-schemeso I assumed it would be the same for _scheme. Rereading your original post I see you successfully tried your original code on OS X, suggesting the error is Windows specific. My long-ago experience with DLLs on Windows is that they're a bit wack: you have to mess around with dllexport declarations or something, but I don't know how all this busy work actually affects the generated DLL. I can only suggest spending some time w/ Google in hopes of more enlightenment. N.
