Hello,

Im getting the error

Command /Developer/usr/bin/gcc-4.2 failed with exit code 1

and when the full log is opened, the error is more accurately listed as:

collect2: ld returned 1 exit status

from this simple Cocoa script:

#import "Controller.h"

@implementation Controller

int skillcheck (int level, int modifer, int difficulty)
{
    if (level + modifer >= difficulty)
    {
        return 1;
    }
    if (level + modifer <= difficulty)
    {
        return 0;
    }

}

int main ()
{
    skillcheck(10, 2, 10);
}

@end

the .h file is this:

//
//  Controller.h
//

//

#import <Cocoa/Cocoa.h>

@interface Controller : NSObject 
{
    int skillcheck;
    int contestcheck;
}

@end

and no line was specified that the error came from, does anyone know what the source of this error is, and more importantly, how to fix it?

EDIT:

I removed the class so now I have this:

//
//  Controller.m
//
//  Created by Duo Oratar on 15/01/2011.
//  Copyright 2011 __MyCompanyName__. All rights reserved.
//

#import "Controller.h"

int skillcheck (int level, int modifer, int difficulty)
{
    if (level + modifer >= difficulty)
    {
        return 1;
    }
    if (level + modifer <= difficulty)
    {
        return 0;
    }

}

int main ()
{
    skillcheck(10, 2, 10);
}

and for the .h file:

//
//  Controller.h
//
//  Created by Duo Oratar on 15/01/2011.
//  Copyright 2011 __MyCompanyName__. All rights reserved.
//

#import <Cocoa/Cocoa.h>

and the log says: (thanks to the guy who said how to open it)
