Link error while accessing NSSpeechSynthesizer

I'm trying to compile a trivial command-line tool with XCode:

#import <Cocoa/Cocoa.h>

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    //NSSpeechSynthesizer *speeker = [[NSSpeechSynthesizer alloc] initWithVoice: nil];

    NSLog(@"%@", [NSSpeechSynthesizer availableVoices]);

    NSLog(@"Hello, World!");
    [pool drain];
    return 0;
}

and even thought I'm importing Cocoa.h, I'm getting a link error:

Undefined symbols:
"_OBJC_CLASS_$_NSSpeechSynthesizer", referenced from: objc-class-ref-to-NSSpeechSynthesizer in byc.o ld: symbol(s) not found collect2: ld returned 1 exit status

Anybody knows what's going on???

You imported the header, so compilation worked, but linking failed because you didn't link against a framework that provides NSSpeechSynthesizer. You need to link against either the Application Kit framework (in addition to Foundation) or the Cocoa umbrella framework (instead of Foundation).

Whichever framework you choose, add it to your Linked Frameworks group in your project's group tree (by right-clicking on the group and choosing “Add Existing Framework”), and make sure you also add it to your target.
