'a': interface is not a COM interface; will not be emitted to IDL
An interface definition that you may have intended as a COM interface was not defined as a COM interface and therefore will not be emitted to the IDL file.
See Interface Attributes for a list attributes that indicate an interface is a COM interface.
The following sample generates C4096:
// C4096.cpp
// compile with: /W1 /LD
#include "windows.h"
[module(name="xx")];
// [object, uuid("00000000-0000-0000-0000-000000000001")]
__interface a
{
};
[coclass, uuid("00000000-0000-0000-0000-000000000002")]
struct b : a
{
}; // C4096, remove coclass or uncomment object
