NSAutoreleasePool is unavailable

Question

I am following \"Programming in Objective-C\" 3^rd edition and I am having problems with the first example.

I keep getting this error:

Answer 1

The compiler is being asked to compile the file with ARC (automatic reference counting) enabled. Turn that off or, better yet, modernize your example:

int main (int argc, const char * argv[]) {
    @autoreleasepool {
        NSLog (@"Programming is fun!");
    }
    return 0;
}

(No, I can't tell you how, specifically, to turn off ARC, if that was the route you were to go down due to the aforementioned NDA.)
