Undefined symbols for architecture armv7 iOS 7.0

In Xcode when I build the app using "Deployment Target" 6.0 or 6.1 it works fine but if I change the target to 7.0 or higher I get undefined symbols error. I've tried removing the framework and adding it back in but still can't seem to get it to build. Not sure if this makes a difference but I have to use "-all_load" for "Other Linker Flags" for this framework. I've also made sure that "Valid Architectures" has armv7 included but I still can't figure this out. Can anyone help me out or point me in the right direction?

Undefined symbols for architecture armv7:
 "std::ios_base::Init::~Init()", referenced from:
     __GLOBAL__I_a in G4XSwiper(DownSample.o)
     __GLOBAL__I_a in G4XSwiper(FskController.o)
     __GLOBAL__I_a in G4XSwiper(WavBuffer.o)
     __GLOBAL__I_a in G4XSwiper(AE_ManchesterRealTimeDecoder.o)

try to set -ObjC -lstdc++ in Other Linker Flags or add the libstdc++.6.dylib in Project->Targets->Build Phases-> Link Binary With Libraries.
