If you called a different function name instead of a template one, I get the
following error:
t.cc: In function �void foo(const A<T>&)�:
t.cc:7: error: there are no arguments to �foo1� that depend on a template
parameter, so a declaration of
�foo1� must be available
t.cc:7: error: (if you use �-fpermissive�, G++ will accept your code, but
allowing the use of an
undeclared name is deprecated)
template <class T> struct A { T t; };
// Swap following 2 functions to get conforming C++
template <int i> struct B {static const int t = i;};
template<class T> void foo(const A<T>& data)
{
foo1((int)data.t);
}
void foo1(int data);
In fact this has nothing to do with dependent or not, see the following code
(which gives the same error
message in 3.3.3 also):
template <class T> struct A { T t; };
// Swap following 2 functions to get conforming C++
template <int i> struct B {static const int t = i;};
template<class T> void foo1(const A<T>& data);
void foo(const A<int>& data)
{
foo1((int)data.t);
}
void foo1(int data);
So the error message problem, in fact that is PR 17166 which I am going to mark
this as a dup of.
