Xcode Linker

I ran into an interesting scenario where I have a static library used by two different apps. App 1 is built and run successfully but App 2 isn't, failing on a missing symbol from the static library. I used 'nm' to verify that symbol was indeed undefined. So my question is what causes this difference and how is possible for App 1 to be built with success (shouldn't the linker resolve all the symbols at build time)? 

Note that the library is  made out of a set of C++ code and the apps are written in Objective-C.
