Compiler Warning (level 1) C4926

  • Article

'identifier': symbol is already defined: attributes ignored

A forward declaration was found but an attributed construct with the same name already exists. The attributes for the forward declaration are ignored.

The following sample generates C4926:

// C4926.cpp
// compile with: /W1
[module(name="MyLib")];

[coclass]
struct a {
};

[coclass]
struct a;   // C4926

int main() {
}
