Objective-C runtime via FFI

[Boris D.]

Hello, I am interested in interacting with the Objective-C runtime from other languages through FFI bindings.

In particular, I need to be able to load Foundation or other classes dynamically. What needs to be done to load these classes in the runtime? Here's an example illustrating the issue I'm facing:

// clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` simple.c -o simple

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])

{

Class c = objc_getClass("NSObject");

printf("Got a class: %s\n", c ? "pass" : "fail");

return 0;

}

Currently it fails.
