Hi Jim,looks like no one who really knows this stuff is offering anything - so I will suggest some of my naive solutions / possibilities:
- as far as I know C functions, structs etc are brought into macruby by the bridgesupport project:
http://bridgesupport.macosforge.org/trac/ - however I cannot seem to find much information on it - however they do their stuff, you could copy - if you could find some docs ;-)
- you could just use C in ruby the normal way via the inline gem
http://www.zenspider.com/ZSS/Products/RubyInline/ - works for me so far with simple stuff. I thought I read somewhere you could also use Objective C with this gem - but I cannot find anything on google at the moment.
- or you could proxy through a custom objective C class - eg I managed to proxy some opengl function calls (not that there is a need to if you have a NSOpenGLView class - it was more a proof of concept) - alas it failed when calling GLUT functions (malloc errors).
Hope one of those helps you, I would be curious as to how you finally do it.
Cheers,
John

Is there a way to expose some c structs and functions from a custom Objective-C framework to MacRuby?
For instance, in my framework I have a 3-D point struct, such as:
typedef struct {
CGFloat x, y, z;
} JPoint3;
In addition, I have creation functions such as 'JPoint3Make(x, y, z)' etc.
How do I make these usable from MacRuby, like NSPoint and NSMakePoint are?
Jim
