How to enhance LiveCode?

[DevBoyLars]

Hi there,
how can I enhance LiveCode? If I need a feature, like the finger-scanner on iOS, how can I access them?

[Klaus]

HI Lars,

you need (to write) an external for this kind of enhancements!
Here you find the SDK at the bottom of the page:

Hi Klaus,
ok, I know this, but how to start? Are there any examples out there? Tutorials?

[Klaus]

Ah, OK, sorry, that (Subj) C++--- stuff is way over my head

[DevBoyLars]

ObjectC is not the problem for me, but I need a way to start

I, for my part, is interested in building externals for the mac. Since the switch to a more cocoa friendly version of livecode, has the externals SDK been updated (I mean desktop, not iOS)? I specifically need 64 bit support for scientific computations, and I would like to use the accelerate framework, which is optimized for multicore processors.
