Hi,

I am trying to use templates recursively to define (at compile-time) a d-tuple of doubles. The code below compiles fine with Visual Studio 2010, but g++ fails and complains that it "cannot call constructor 'point<1>::point' directly".

Could anyone please shed some light on what is going on here?

Many thanks, Jo

#include <iostream>
#include <utility>

using namespace std;

template <const int N>
class point
{

private:
  pair<double, point<N-1> > coordPointPair;

public:

  point()
  {
    coordPointPair.first = 0;
    coordPointPair.second.point<N-1>::point();
  }

};

template<>
class point<1>
{

private:
  double coord;

public:

  point()
  {
    coord= 0;
  }

};

int main()
{
  point<5> myPoint;

  return 0; 
}
