Cocoa application built under OS X 10.6 crashes on OS X 10.7

Question

My Cocoa application works fine on Mac OS X 10.6, however if I try to run it under 10.7, it crashes with the following stack trace:

Thread 5 Crashed:

Can you please tell me, if it possible to fix the problem without rebuilding application under 10.7? Maybe I should somehow statically link Cocoa libraries and frameworks I'm using?

Please help!

Answer 1

Without rebuilding your whole program, you may have to check the version of certain libraries. If the system library changed from 10.6 to 10.7 then some of your call may need to be updated.

I don't know which dependencies you have, but maybe try to see if you have the latest version for your OSX 10.7

EDIT : I don't know if the library that contain the object calendar is something you built or not, but I would start by looking at its dependencies.

实际上，问题与NSLog类有关，出于某些愚蠢的原因，它在10.7中似乎是非线程安全的...
