class-dump gives error "Error: Cannot find offset for address in dataOffset for addr"
I am trying to dump the springboard headers from my mac
using following command
class-dump /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/CoreServices/SpringBoard.app/SpringBoard -H
but I am getting the following error :
2010-09-13 16:14:23.325 class-dump[1955:10b] Error: Cannot find offset for address 0x38a56a2c in dataOffsetForAddress:
I downloaded the class-dump command line tool from http://www.codethecode.com/projects/class-dump/ and copied the class-dump file to my usr/bin/ directory
So anyone please let me know what went wrong???
