BUG: C2065 in External Definition of Nested Member Function
'Article ID: Q151586

Creation Date: 27-MAY-1996

Revision Date: 18-JUL-1996' The information in this article applies to:


 * The Microsoft C/C++ Compiler (CL.EXE), included with: Microsoft Visual C++, 32-bit Edition, versions 2.0, 2.1, 2.2, 4.0, 4.1, 4.2

SYMPTOMS

An undeclared id error C2065 in the external definition of nested member function for parameters of user-defined type, enum, struct, and class in the enclosed scope appears when typedef is used.

RESOLUTION

Please refer to the More Information section of this article for a sample code and workarounds.

STATUS

Microsoft has confirmed this to be bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The following code reproduces the error when compiled. The undeclared identifier error is reported for the enum E declared in the enclosed scope. Declarations in global scope do not produce this error.

//Compile option needed -- none

struct A {

enum E {e = 1};

struct B{              void g(int); void f(E); };   };

typedef A::B C;

void C::g(int i){} void C::f(E e){}  // error C2065: 'E' : undeclared identifier WORKAROUND


 * Define nested function internally. In the example, define function f(E) inside struct B.
 * Use C::f(A::E e) or, A::B::f(E e) for C::f(E e).
 * }
