[MacRuby-devel] Exposing c structs and functions

[John Shea]

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
