the problem:
I use a typedef inside a class template, than I use this type
(dim_v<N1>::Typ e) to define the argument of a template function f
but when I call this function from main, the compiler (gcc 3.4.1)
tell me: "no matching function found".
If someone, more expert than me, could tell me what is wrong
I would be very happy
the code:
=============== =============== =============== =============== ===
file: scratch.h
---------------------------------------------------------------
#include <iostream>
typedef int dim_t;
typedef unsigned int rank_t;
template<typena me T, rank_t N>
class V
{
private :
T dm1;
rank_t dm2;
public :
V(T p1, rank_t p2) :
dm1(p1), dm2(p2+N)
{
}
rank_t get_2()
{
return dm2;
}
};
template<rank_t N1>
class dim_v
{
public :
typedef V<dim_t, N1> Type;
};
template<rank_t P>
void f(typename dim_v<P>::Type v)
{
std::cout << std::endl << v.get_2() << std::endl;
}

f(v); // ERROR !
return 0;
