RE: Problem with code or gcc?

["Kedzierski, Artur CIV NAVSURFWARCENDIV CORONA" <artur dot kedzierski at navy dot mil>]

	Philippe and Ryan, thank You for your responses.
	One thing that I find it strange is that I can use
MyStruct::CONST in other ways without a problem:

MyStruct m;
int a = m.CONST
std::vector<int> v;
v.push_back(static_cast<int>(m.CONST));
if (b == m.CONST) 
  ...

	However, only when I use 'v.push_back(m.CONST)', I
get a linker error. Shouldn't I get a linker error in
those other cases?

Hello,

This is not a valid C++ code, you cannot define the
value of CONST inside the struct declaration.

A more correct code would be :

struct MyStruct {
 static const int CONST;
};

const int MyStruct::CONST = 1;

Regards,

PH
