My enum is not a class or namespace

Question

Hi I have files called MyCode.h and MyCode.cpp

In MyCode.h I have declared

enum MyEnum {Something = 0, SomethingElse = 1};  class MyClass {  MyEnum enumInstance; void Foo();  };  

Then in MyCode.cpp:

#include "MyCode.h"  void MyClass::Foo() {     enumInstance = MyEnum::SomethingElse; } 

but when compiling with g++ I get the error 'MyEnum' is not a class or namespace...

(works fine in MS VS2010 but not linux g++)

Any ideas? Thanks Thomas

The syntax MyEnum::SomethingElse is a Microsoft extension. It happens to be one I like, but it's not Standard C++. enum values are added to the surrounding namespace:

 // header  enum MyEnum {Something = 0, SomethingElse = 1};   class MyClass {   MyEnum enumInstance;  void Foo();   }   // implementation  #include "MyClass.h"   void Foo() {      enumInstance = SomethingElse;  }
