Sorry,
You're right I've made a mistake declaring my class but that wasn't
that I will want to understand.
But I have modified like you said, and like was the header file in the
first place.
So there is the file and the errors :
/**
* @file Vector2.h
* @brief A container with 2 components
* @author Alternative Shift (Guillaume Rous)
* @date 30/11/09
*/
#ifndef VECTOR2_H
#define VECTOR2_H
#include <math.h>
#include <typeinfo>
#include "../config/Define.h"
#include "../utilities/Utils.h"
namespace AS
{
/**
* @class CVector2
*
* @brief This class represents a vector with 2 components and its
main operations
*/
template <class T>
class CVector2
{
public :
CVector2(T _X, T _Y);
};
template <typename T>
inline CVector2<T>::CVector2(T _X, T _Y) :
X(_X),
Y(_Y)
{
}
} /* namespace AS */
#endif /* VECTOR2_H */
And there is the errors :

I want to know how to use template for Android NDK.
Because I try to port a code who was functionnal for C++ Compiler
(Unix), and for iPhone.
But I want to understand why the use of template, that I had before
doesn't work with the Android Compiler
