Hi Ian,
unfortunately I can't help you with automatic code generation but i've
written a binding for libSDL (and libSDL_image) manually. It's not
complete but covers quite a usable part of SDL (video, events, joystick
and some more). If it helps you in any way, feel free to use / fork the
code. It's on github:

I'm playing around with an FFI for SDL. Rather than slog through all
the headers by hand, I went looking for some code that may do a bit of
the parsing and translation. On PLaneT, I found dherman's c.plt:
http://planet.racket-lang.org/display.ss?package=c.plt&owner=dherman
I got stuck when it appeared that I'd need to provide it with a list
of symbols that were typedef-ed:
http://planet.racket-lang.org/package-source/dherman/c.plt/4/0/planet-docs/c/parsing.html#(part._include)
I bit of preprocessing seems to make this still quite a bit of work:
gcc -D "__extension__=" -D "__attribute__(ARGS)=" -E
/usr/include/SDL/SDL.h | sed '/^\#/d' | indent -st -i2 |grep -vE
'^[[:space:]]*$' > sdl.h
Has anyone else gone down this road before? Also, Besides Eli's
paper, any general advice for Racket FFIs?
Thanks,
