specialized constructor in specialized class

[Frank Winter <frank.winter@xxxxxxx>]

Dear list,

I try to specialize a copy constructor in a specialized class. I 
keep getting:

"explicit specialization in non-namespace scope class RComplex<double>"

from the compiler. I use GNU g++
gcc version 4.3.4

How can the specialized constructor be defined?

Frank





template<class T> class RComplex
{
public:
  RComplex() {}
  ~RComplex() {}
private:
  T re;
  T im;
};


template<>
class RComplex<double>
{
public:
  RComplex() {}
  ~RComplex() {}

  template<class T>
  RComplex(T arg)
  {
  }

  template<>
  RComplex(int arg)
  {
  }

private:
  double F[2];
};


int main()
{
  int i=1;
  RComplex<double> z(i);

  return 0;
}
