c++ mark enum value as deprecated?

Question

Is it possible to mark an enum value as deprecated?

e.g.

enum MyEnum {
    firstvalue = 0
    secondvalue,
    thirdvalue, // deprecated
    fourthva         


        

Answer 1

you could do this:

enum MyEnum {
    firstvalue = 0,
    secondvalue,
    thirdvalue, // deprecated
    fourthvalue
};
#pragma deprecated(thirdvalue)

then when ever the variable is used, the compiler will output the following:

warning C4995: 'thirdvalue': name was marked as #pragma deprecated

EDIT
This looks a bit hacky and i dont have a GCC compiler to confirm (could someone do that for me?) but it should work:

enum MyEnum {
    firstvalue = 0,
    secondvalue,
#ifdef _MSC_VER
    thirdvalue,
#endif
    fourthvalue = secondvalue + 2
};

#ifdef __GNUC__
__attribute__ ((deprecated)) const MyEnum thirdvalue = MyEnum(secondvalue + 1);
#elif defined _MSC_VER
#pragma deprecated(thirdvalue)
#endif

it's a combination of my answer and MSalters' answer
