when i compile an iOS project with using the three part library, i got "Apple Mach-O linker Error"

Question

I've added a library named "*.a" from three part and added its header file in my XCode project. While I compile the project, there are many "Apple Mach-O linker Error". Here the error info:

Any one help me to fix this issue. Thanks!

Looks like the library uses C++. Try adding libstdc++ to your target.

I've add libstdc++ to my target, but this does not make sense. I don't know how to fix this issue. – Qijin Mar 17 '14 at 05:10

Try to add libstdc++.6 instead – maros Jan 21 '15 at 11:27
Ran into the same issue when trying to build with the Red Laser SDK from eBay. The instructions from their own READ ME doc didn't help but this link did. Thx – xdeleon Dec 08 '15 at 21:25

Thanks it helped me to repair my project, during switching from SDK 6 to SDK 8 had the same errors.

With adding libstdc++6 i could solve my problem.

Try changing the C++ Standard Library from Compiler Default to libstdc++ (GNU C++ standard library) in the Target --- > Build Settings --> C++ standard library

This solved my problem .

The answer from @Phillip Mills was great hint to solve many errors but instead of that to terminate all errors I changed C++ Standard Library settings under Apple LLVM 8.0 - Language - C++ to libstdc++ as shown in the screenshot. I have safely removed the libstdc++ library from the target.

when i compile an iOS project with using the three part library, i got "Apple Mach-O linker Error"
