If we have two template classes in hierarchy and try to take type of the
topmost class, gcc shows error message while VC 8.0 and Comeau C/C++ 4.3.3 does
not.
The following exapmle shows code that generates the error:
template <typename T>
class A
{
public:
typedef int TType;
private:
typedef T tmp;
};
template <typename T>
class B : public A<T>
{
public:
typedef char* TType;
private:
typedef T tmp;
};
template <typename T>
class Test
{
public:
static void test()
{
typename B<T>::A::TType a = 0;
typename B<T>::TType b = "test";
}
};
int main(int argc, char* argv[])
{
Test<int>::test();
}
Error message is following:
test.cpp: In static member function `static void Test<T>:
:test() [with T = int]':
test.cpp:35: instantiated from here
test.cpp:27: error: no type named `A' in `class B<int>'
