mach-o linker errors with metaio

Question

I am working with Metaio SDK and cloud plugin and I can not get past a huge collection of mach-o linker errors in xcode 5. Here are a few, but I have 118 of them:

Undefined symbols for architecture armv7s:
  "std::__throw_logic_error(char const*)", referenced from:
      tesseract::WordListLangModel::AddString32(int const*) in metaioSDK(word_list_lang_model.o)

After setting deployment target to 6.0, I have cut this down to 6 errors

ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

The error you shown for iOS 6 means, that some of the frameworks are missing, Please add all these frameworks shown in the image to make it work with iOS 6.

and this link can help you as well.

New Update:

After checking your code, i found some problems in the your project, You were missing the StoreKit and StoreKitUI and MeidaPlayer Frameworks.

And some of your build setting configuration was not correct. Please use the exact configurations show in this images. Other Linker flag must be like that:

and C Language dialect must be like that:

and this configuration be exactly like this image:

i have tested the your app by using all these configuration and now the app is working fine with iOS7 and iOS 6.
