Question

Am getting a SIGABRT error in my main file, and don’t know what to do.

Maim file is:

#import <UIKit/UIKit.h>

int main(int argc, char *argv[])
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

The error message highlights the line reading:

int retVal = UIApplicationMain(argc, argv, nil, nil);

and reads: “Thread 1: Program received signal: “SIGABRT”

Can you tell me what’s wrong, and what I need to do to get it compile?

Thank you.

It’s an error elsewhere in your application. You’ll have to run the debugger and step through the screen that causes the crash until you reach the line where it jumps to SIGABRT in main. Usually it’ll have something to do with memory management (over-releasing an object and then accessing it) or improper initialisation of UIKit objects, which UIKit then attempts to render (which includes returning an object of the wrong type, or accidentally assigning the wrong tag to a UI element so it’s sent a message it can’t handle). If it’s improper initialisation, though, you should get an additional error printed to inform you of that.

EDIT: Actually, yes, you mention it can’t compile? SIGABRT is a signal sent to the running application, so I don’t see how it can come up during compilation.
