iPhone apps crash if debugged on a jailbroken iPhone OS 2.2.1 (libgcc version?)

Question

Hi,

I'm new to iPhone development. I used a jailbraked iPhone (OS 2.2) for for some time with no problems. Recently I had to upgrade to OS 2.2.1 and after the update I am no longer able to debug apps on the phone. In the console I'm getting the following warning and the apps crash at launch (only when debugged) :

...
warning: UUID mismatch detected with the loaded library - on disk is:
    /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/usr/lib/libgcc_s.1.dylib
=uuid-mismatch-with-loaded-file,file="/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/usr/lib/libgcc_s.1.dylib"
warning: Unable to read symbols for "/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/usr/lib/iPhoneHE.dylib" (file not found).
warning: Unable to read symbols for "/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/usr/lib/libsubstrate.dylib" (file not found).

warning: Unable to read symbols for "/Library/MobileSubstrate/MobileSubstrate.dylib" (file not found).
Program received signal:  “EXC_BAD_ACCESS”.

I searched on the web, but was not able to find clear answers. Is this a familiar problem with iPhone OS 2.2.1 on a jailbraked phone? Is there a solution to this?

Many thanks,

Ori

Answer 1

A little late, but it looks like you're having a problem with MobileSubstrate. Just upgrade to the latest version and to OS 3.1.2 and you'll be fine. (You've probably fixed this by now though...)

Answer 2

I know this is old but I thought I would like to pop in and say that jumping into Safe Mode from SBSettings Power option allowed for Debugging on my jailbroken phone.
