Unit Tests Failure At Xcode 3.2.4, iOS 4.1 SDK Using Hamcrest Assertion

We upgraded to Xcode 3.2.4 with iOS 4.1 SDK, now our tests are failing.

First because of this An internal error occurred when handling command output: -[XCBuildLogCommandInvocationSectionRecorder endMarker]: unrecognized selector sent to instance 0x201aa7200 then we used the patch suggested by apple forums (http://gist.github.com/586296) and now the test fail on the first Hamcrest assertion.

NSNumber * c1 = ...
NSNumber * c2 = ...
assertThat(c1, is(c2))

Here's the log:

-[NSCFNumber conformsToProtocol:]: unrecognized selector sent to instance 0x2116890

Any one see that before? it was working perfectly on 3.1.3 SDK.

This is fixed, by using the latest OCHamcrest as a static library instead of a framework and add -lstdc++ to other linker flags.

Hope that save someone time.
