Analysing iPhone crash log
<p>I got a crash log from a customer using my iPhone app and trying to get symbolic information out of, and failing spectacularly ... what I found online as instruction is this (to be executed on a Mac):</p>

<p>symbolicatecrash crash-log-file.crash symbol-file.dSYM > report-with-symbols.crash</p>

<ul>
<li>crash-log-file.crash is the crash log obtained by the user via iTunes, a text file</li>
<li>symbol-file.dSYM is created by XCode each time you build the application and contains the symbols file (within a series of folders)</li>
</ul>

<p>Unfortunately my attempts have all failed:
- with a version of symbolicatecrash I have (don't recall where &amp; when I found it), the output is identical to the input file, without symbols
- with another version I found on my disk, I get this error message (note: I tried to point to the symbol file itself within the .dSYM tree - still no help):</p>

<p>/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash failedstart.crash ScanBizCards.app.dSYM/Contents/Resources/DWARF/ScanBizCards > crashwithsymbols</p>

<p>Can't understand the output from otool ( -> '\/Developer\/Platforms\/iPhoneOS.platform\/Developer\/usr\/bin\/otool -arch armv7 -l /Users/patrickq/Projects/icr/OCR/newOCR/build/Debug-iphonesimulator/ScanBizCards.app/ScanBizCards') at /Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash line 301.</p>

<p>Help anyone?</p>

<p>I don't even mind doing the math myself for symbols but don't know how to open the symbols file ...</p>
