My app compiles fine on the iPhone simulator running iOS 5.0, but it fails on my older physical iPod touch running iOS 4.2.1.

I'm getting the following error:

Undefined symbols for architecture armv6:
  "_OBJC_CLASS_$_TestFlight", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture armv6

I've looked at other questions about this: Undefined symbols for architecture armv6, Updating to iOS 4.3

But they're solutions do not work. Indeed, TestFlight.h was not in Compile sources, but dragging it to Compile Sources did not change the error message. (There is no TestFlight.m; I have libTestFlight.a in "Link Binary with Libraries"

Similarly, deleting and retyping #import "TestFlight.h" in AppDelegate.m did not change anything.

What else could be causing this compile error on my iPod?

First, a .h file is not a source file, so remove it from "Compile Sources" again.

About the error - you are probably using a version of the TestFlight SDK that does not support armv6 - they re-enabled this architecture in a recent version. Update to the newest version of the SDK and see if that helps.

Click on your project, select

Target

and then goto

Build Phases

In

Compile Sources

added AppDelegate.m, it might not be connected, compiler is unable to find the file. Also see link
