iOS模拟器编译错误

Question

我尝试从Github（https://github.com/smartface/iOS-Emulator）编译iOS模拟器，以便能够在iOS 8.3上使用它，但编译过程失败并出现以下错误：

(null): "_OBJC_CLASS_$_ESpratIOSPlayer", referenced from: (null): "splog(int, char const*, char const*, ...)", referenced from: (null): "SpEventGroup::FireEvent(TEventID, int, char*, SpBrParcelable*)", referenced from: (null): "SpBrParcelable::GetEventGroup()", referenced from: (null): Linker command failed with exit code 1 (use -v to see invocation)
