vs下编译没有问题，g++下提示错误(pdfium)

#include <iostream>
namespace v8 {

	namespace internal {
		enum FunctionKind {
			kNormalFunction = 0,
			kArrowFunction = 1,
			kGeneratorFunction = 2,
			kConciseMethod = 4,
			kConciseGeneratorMethod = kGeneratorFunction | kConciseMethod,
			kDefaultConstructor = 8,
			kDefaultConstructorCallSuper = 16
		};
		inline bool IsValidFunctionKind(FunctionKind kind) {
			return kind == FunctionKind::kNormalFunction ||
				kind == FunctionKind::kArrowFunction ||
				kind == FunctionKind::kGeneratorFunction ||
				kind == FunctionKind::kConciseMethod ||
				kind == FunctionKind::kConciseGeneratorMethod ||
				kind == FunctionKind::kDefaultConstructor ||
				kind == FunctionKind::kDefaultConstructorCallSuper;
		}

		inline bool IsArrowFunction(FunctionKind kind) {

			return kind & FunctionKind::kArrowFunction;
		}


		inline bool IsGeneratorFunction(FunctionKind kind) {

			return kind & FunctionKind::kGeneratorFunction;
		}


		inline bool IsConciseMethod(FunctionKind kind) {

			return kind & FunctionKind::kConciseMethod;
		}


		inline bool IsDefaultConstructor(FunctionKind kind) {

			return kind & FunctionKind::kDefaultConstructor;
		}


		inline bool IsDefaultConstructorCallSuper(FunctionKind kind) {

			return kind & FunctionKind::kDefaultConstructorCallSuper;
		}

}

}
namespace i = v8::internal;
int main()
{
    std::cout << "Hello World!\n"; 
	system("PAUSE");
}

　　

 

编译器差异，直接if(x == F)就行了

转换为问题： linux g++编译器处理枚举类型的问题
