Hi!
Why can I compile this in BuilderX, but not in BCB6?
And is there a solution to this?
template <typename T, unsigned int N>
class RefArray
{
RefArray<T,N>(T * pElements)
{
}
};
template <typename T>
class RefArray<T,1>
{
RefArray <T,1>(T* pElements)
{
}
};

It seems that a problem with non-type template parameters was fixed
from C++ Builder 6 to C++BuilderX.

My first shot would be to try substituting the unsigned int parameter
by a type parameter. Something like:
template <unsigned int N>
struct IntToType
{
enum
{
value = N
};
};
template <typename T, typename IntToTypeInstance>
class RefArray
{
RefArray(T * pElements)
{
}
};
template <typename T>
class RefArray<T, IntToType<1> >
{
RefArray(T* pElements)
{
}
};
