Would really like an end-to-end guide on compiling C with objective C (and possibly some example code in gambit that shows the interfacing you did).

I'd love to be able to do this with ECL (http://ecls.sourceforge.net/) to build apps in common lisp for iOS (possibly android). I know about MOCL, but I'm a pretty cheap guy, so would rather stick to open technologies and do the work myself.

I'm not a scheme guy, but until you get a writeup done, would you mind posting any info you have on interfacing gambit with iOS?

Good work, and thanks for sharing!!
