Until xcode 4 final (I was using 3.latest and 4 GM for the time it was available) this didn\'t happen. When I upgraded to xcode 4 final version, I started getting a linking
In iOS SDK 4.3, it looks like the linker will simply refuse to use a armv6 library in an armv7 binary - this wasn't the case before.
That's why I had to update the http://code.google.com/p/ios-static-libraries/ project to generate both armv6 and armv7 versions of the libraries.
