SYMPTOMS
An ambiguous C2966 error is generated if any members of a nested template class are defined externally. The sample code shown in the "More Information" section of this article reproduces this problem and gives the following error message:
RESOLUTION
Define members of a nested template class inline only.
NOTE: external definitions with the inline keyword will still generate the ambiguous C2966 error.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.
MORE INFORMATION
Sample Code to Reproduce Problem
// Compile option needed: none
template<class T> class Outer {
public:
class Inner {
public:
static T sobj;
static T smfunc(T arg);
};
};
//Initialize nested class static object
template <class T> T Outer<T>::Inner::sobj = T();
// Out-of-line definition of nested class static member function
// Moving this definition inside class resolves the error
template <class T> T Outer<T>::Inner::smfunc(T arg)
{
return arg + sobj;
}
