gcc-4.2 failed with exit code 1 iphone

Question

I've seen this error with different variations on discussion forums but being a non programmer I'm not sure how to progress this.

Basically I have code which I found to help me with changing the background colors of cells on a grouped uitableview. The code introduced a line as such:

CGContextAddArcToPoint(c, minx, miny, midx, miny, ROUND_SIZE);

This gave an error indicated that it wasn't declared, so I added to my .h file the following under import uikit:

#import <UIKit/UIKit.h>
#define ROUND_SIZE 10

Now it shows that I have an error:

Command/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 iphone

Some discussions talk about libraries but because I don't have a programming background I don't understand what to do. I also see that some people show a log output but I'm not sure where that comes from as I don't get any debug windows because I'm guessing it doesn't get that far. I simply click 'Build and Go' and I get this error in the Message window.

Any thoughts?

Answer 1

As you can see from the many different responses this error is caused by many different problems. Luckily, I have found the Meta Solution!

In xcode, right click the error line and choose "Open These Latest Results as Transcript Text File". This will open the real xcode output log, which should contain a better description of the error then was previously seen.

I have gone through that same problem. There may be some file which has no refference . You can see that type of file in red letter. Remove that file.

Answer 3

You probably don't have the CoreGraphics.framework added to your frameworks list.

To make sure, click the "Frameworks" folder on Xcode. If the framework isn't listed on the table to the right, you'll need to add it by right-clicking the Frameworks folder, chooseing "Add Existing Framework..." and then choosing it from the list.

I've found the problem after seeing the Build Results window that Dave mentioned (thank you!!!). I had a different version of the same .h and .m file because I was testing with different code. I deleted the unnecessary files as it was seeing something in there as a duplicate. The build was successful. Thank you!
