symbolicatecrash with XCode 4.2 not symbolicating system symbols

This is a very weird problem. I think I must be doing something wrong, but I don’t know what it is. I’ve been using symbolicatecrash for several years with no problems. The issue I’m seeing is that symbolicatecrash is not showing symbols for the system libraries, but it IS showing symbols for my application. I’ve tried everything I can think of to resolve this with no luck.

Note that I’m getting the same results on three different machines, 2 Lion, 1 Snow Leopard.

  • Modal UINavigationController - I cant stop rotation
  • OCUnit Tests giving errors in classes not being tested
  • xcode Organizer “Validate” fails with the “No other information is available about the problem.” message
  • UICollectionView align logic missing in horizontal paging scrollview
  • Use SIP in iPhone app
  • Prevent / Disable Xcode scroll navigation
  • Example command line:
    /Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash /Users/mike/Downloads/mycrash-iPad.crash

    Note also that I get the same results when I drag the file into the logs section of the XCode 4.2 logs organizer window and wait for XCode to symbolicate the file.

    Here’s an example of a crash in my code with the partially symbolicated symbols:

    I’ve run the symbolicate crash command with -v and it’s finding the app.dSym files okay, it just doesn’t seem to be finding the library symfiles which seems to be the opposite problem most people are having. Facepalm.

    For example, here’s the output from a -v run for the CoreFoundation lib:

    I really am at a loss to figure out what to try next.

    Does anyone have any ideas? I’m fresh out. Your help will be much appreciated!

    thanks,

    More info, now I’m getting an error in the symbolicatecrash output.

    2 Solutions Collect From Internet About “symbolicatecrash with XCode 4.2 not symbolicating system symbols”

    The following solved the problem for me:

    • Delete the folder ~/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)
    • Reattach your iOS device and it will automatically import the correct symbols.

    After that the crash reports could be symbolicated correctly. (to re-symbolicate a crash report, open the Organizer, click on ‘Reveal in Finder’ and delete the symbolicated version)

    It looks like this is an acknowledged bug with Xcode 4.2 and iOS 5:

    A new Xcode beta was released for Lion yesterday, does that work for you? I can’t try it myself because it’s not available for Snow Leopard yet.
