Linker errors with library that I know is in the project

So I'm working with the 3dar SDK, and I had no problem building a standalone application that implemented the sdk and the resulting SM3Dar.h header. But now that I'm trying to use the same sdk as part of a larger project it doesn't seem to be functioning correctly. It seems like it knows the header file is in there but is not communicating correctly with that and the library. I'm trying to run it on an iPhone 5, and I have the latest XCode.

But I receive these errors

Add "-lc++" to Other Linker Flags in your Build Settings.

I believe the library was built for only armv7 not armv7s. To confirm that this is the problem, configure your project to build for armv7 only in the project build settings and see if that works. If that is the case, your options are to either get an updated version of the library or to build your code for armv7 only.
