Elaborated-type-specifier for a scoped enum must not use the ‘class’ keyword

c++, c++11, elaborated-type-specifier, enum-class, g++

Solution

Check the type you are deriving the `enum class` from exists. In this case, there was no typedef specified for `int8`.

Problem

I have the following enum specification: ``` enum class FaceDirection : int8 { Down, Up }; ``` g++ 4.8.1 gives the following error: warning: elaborated-type-specifier for a scoped enum must not use the ‘class’ keyword What causes this?
