iOS CLLocation Linker Error

[twain249]

I have this line in my code

CLLocation *myLoc = [[CLLocation alloc] initWithLatitude:coordinate.latitude
						longitude: coordinate.longitude];

and I have this in my .h file

#import <CoreLocation/CoreLocation.h>

but when I try to build I get this error

Ld build/Debug-iphonesimulator/Metro-Atlanta-Arts-App.app/Metro-Atlanta-Arts-App normal i386
