SIGABRT error when building

[Chickenboy]

this block below is located in my Other Sources file in main.m and i get a SIGABRT error at this code below when i try to build the program

#import <UIKit/UIKit.h>

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

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil);          >>>Thread 1: Program received signal: "SIGABRT".
[pool release];
return retVal;
}

when i look at the debug navigator it says Thread 1: Stopped after step at the leave step below

0x9470a14c  <+0000>  push   %ebp
