C1133: Such an initialization requires STATIC CONST INTEGRAL member

[ERROR]

Description

A static CONST member of integral type may be initialized by a constant expression in its member declaration within the class declaration.

Example

  int e = 0;

  class A{

  public:

    static int a = 1; // ERROR: non-const initialized

    const int b = 2; // ERROR: non-static initialized

    static const float c = 3.0;// ERROR: non-integral

                               // initializer

  static const int d = e; // ERROR: non-const initializer

    // ...

};

Tips

  class A{

  public:

    static const int a = 5; // Initialization

    // ...

};

  const int A::a;             // Definition

or the other way round:

  class A{

  public:

    static const int a;     // Definition

    // ...

};

  const int A::a = 5;         // Initialization
