Getting error after updating xcode 5.0 to 5.1

Question

I have updated the xcode 5.0 to 5.1 today. I run the existed project but getting the error now. I had no issues while running that project on 5.0 version. The error is below :

ld: library not found for -lIOKit
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please someone help.

I re-added the frameworks but now I get another error which is below

ld: 62 duplicate symbols for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Try going to your project configuration -> Build Settings -> Architechtures -> Valid architectures

Check if you've got the armv7s label duplicated.

You can also try to set to YES the Build Architechtures Only.

Answer 2

请检查：-转到构建设置，在搜索栏“ GCC”中写入，检查天气编译器是否已安装（LLMV 5.xx）。
