Can't symbolicate crash log - why?

Question

I have a crash file from a user, and a DSYM dir from the xarchive build for the app store. Despite that, I don't get a translation of addresses to function names. Can anybody tell me why?

Command line:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash TypO\ Lite_2012-05-26-221125_GC-64-4G-iPad.crash TypO\ Lite.app.dSYM

Output:

Error: No developer directory found at /Developer. Run /usr/bin/xcode-select to update the developer directory path.

Have you check this somewhat related question: http://stackoverflow.com/questions/3498389/why-would-one-crash-log-symbolicate-and-not-another — nhahtdh, May 27 '12 at 09:12
try to drag and drop the crash log in the xcode organizer .. it will be symbolicated automatically. — Malek_Jundi, May 27 '12 at 10:20
Hmm, dragging at dropping does nothing except giving me a message about that XCode is scanning the file, but nothing else happens. — Anders Sewerin Johansen, May 27 '12 at 11:04

Could you please add the -v parameter. That should give you some lots of errors for each library it tries to symbolicate. I suspect neither the iOS 5.1.1 symbols, nor the app specific symbols could be found via spotlight.

Did you upgrade a device to 5.1.1 and did Xcode extract the symbols? Check ~/Library/Developer/Xcode/iOS DeviceSupport. It should contain a directory named 5.1.1 (9B206).

Regarding your apps symbols: was that from a debug build? If so, did you execute another build afterwards? If so, this is the reason it won't symbolicate the app specific items too. The symbolication script needs the app binary and the exact corresponding dSYM for it.

See this answer for more details on that: backtrace still not readable after symbolicating iPad crash log

Added the information. Seems to me that I just don't have the right build available anywhere :( – Anders Sewerin Johansen Jun 01 '12 at 08:36
Right. To get the iOS symbols, update any of your developer devices to 5.1.1 and connect it to Xcode. It should then import the symbols. Regarding your app, make sure to use Xcode archive for every beta or release distribution. This will archive the dSYM and app binary for later use, e.g. symbolication of crash reports. If you don't archive, every build run will overwrite the files from the last build, making it impossible to symbolicate. You could in addition use a crash reporting framework and or services to automate everything, e.g. HockeyKit.net or HockeyApp.net (I am a developer of both) – Kerni Jun 01 '12 at 09:53

I suppose the answer is right in front of you. The first line of your log states:

Error: No developer directory found at /Developer. Run /usr/bin/xcode-select to update the developer directory path.

Your Xcode.app is in /Applications. Formerly (before Xcode was delivered via the Mac App Store), Xcode used to be in /Developer. So if you run:

/usr/bin/xcode-select -print-path

The output will be: /Developer While it should be /Applications

So the solution is to run:

sudo /usr/bin/xcode-select -switch /Applications

(It must be run as root to change the setting). Then restart Xcode and click on the log in Organizer. Or import the log if it is not in the list. Now it should symbolicate correctly.

BTW, thanks for your verbose question. It brought me to this solution, because I was having the same problem right now. And because I used Xcode, I did not see the error message about Xcode-select.

I am wondering if anybody that had Xcode installed in /Developer has the same problem.

Alternatively: Do what I did, and sign up with Crittercism. They have a very nice system for error tracking and reporting, that will also symbolicate your crash reports. You do have to upload the DSYMs, but from that point on their system will properly match DSYM files to the crashes. — Anders Sewerin Johansen, Aug 07 '12 at 16:13
Switching to /Applications returned an error "invalid developer directory" for me, but switching to "/Applications/Xcode.app/Contents/Developer" as suggested by http://stackoverflow.com/a/17980786/462162 worked. — arlomedia, Feb 03 '14 at 20:44

Can't symbolicate crash log - why?
