Guard Malloc in Xcode 2.5


  • Subject: Guard Malloc in Xcode 2.5

I attempted to enable Guard Malloc in Xcode 2.5 under 10.5.1. When I launched my program in the debugger, it exited immediately saying it could not find /usr/lib/libgmalloc.dylib. Sure enough, there was no such library in /usr/lib.

I found a lib called libgmalloc.B.dylib in the usr subfolder of the Xcode2.5 folder, so I copied it to /usr/lib. After doing so, I saw the following error:

dyld: Symbol not found: _NXCreateChildZone
Referenced from: /usr/lib/libgmalloc.dylib
Expected in: /usr/lib/libSystem.B.dylib

This leads me to wonder whether I have a messed-up install, but I've seen no other similar problems. GDB itself seems to work fine. Has anyone had any success with Guard Malloc in this configuration?

David Z.
