Xcode 9 compile error after integrating weex sdk

Question

I builded the WeexSDK.framework by myself with Xcode 9. Then integrated the framework into my project. Got weird compile error log when build my app, could someone help me?

Undefined symbols for architecture arm64:
  "___llvm_profile_runtime", referenced from:
      ___llvm_profile_runtime_user in WeexSDK(WXDisplayQueue.o)
      ___llvm_profile_runtime_user in WeexSDK(WXResourceRequestHandlerDefaultImpl.o)
      ___llvm_profile_runtime_user in WeexSDK(WXSwitchComponent.o)
      ___llvm_profile_runtime_user in WeexSDK(WXRootView.o)
      ___llvm_profile_runtime_user in WeexSDK(WXRecyclerUpdateController.o)
      ___llvm_profile_runtime_user in WeexSDK(WXRecyclerComponent.o)
      ___llvm_profile_runtime_user in WeexSDK(WXThreadSafeMutableDictionary.o)
      ...
     (maybe you meant: ___llvm_profile_runtime_user)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Add -fprofile-instr-generate to Other Linker Flags solved the compile errors.
