Hi all,
I'm wondering if it is possible to directly interface with the
objective-c runtime, as I've read [1] and I have some random
crashes in
my code right now.
Yes, it's possible since the Objective-C runtime is plain C
functions. You need to show us some code to be able to help you.
Someone can share some experience? I'm on 10.9...
To interface with Objective-C there are three options:
* Use the Objective-C runtime functions directly [1]
+ Works now, no language or library support is needed
- Cumbersome
- Verbose
- Easy to make mistakes
* Use an Objective-C/D bridge [2]
+ Fairly simple to use
- Bloat, both template and virtual method bloat. We're talking
60MB Hello World
* Extend the language to be ABI compatible [3, 4]
+ The compiler outputs the same code as the Objective-C
compiler would
+ Easy to use (or as easy as using Objective-C would be,
sometimes easier)
- Requires language support
I tried all of these options and personally I think the third
options is the best. As of a coincident I just finished (except
for exceptions) porting D/Objective-C to 64bit.

Hi Jacob,
Actually I'm using [1], that's why I was wandering about eventual
problems related to objc_msgSend_stret.
But I think that now the plan is to tryout [3]: that's the most
logical solution after all...
