Hi there!

I have read  there are problems with gcc-2.1 and template classes, which
define non-inline element functions. Does anyone know, if there are problems
generating friend functions for template classes?
How can I correctly build something like that:

#include <iostream.h>

template <class A, class B>
class hubo {
   A avar;
   B bvar;
  public:
   hubo(void):avar(0),bvar(0) {}
   hubo(A a, B b):avar(a), bvar(b) {}
   friend ostream& operator<<(ostream& o, hubo& h);
   
   friend istream& operator>>(istream& i, hubo& h)
     {
       return i >> h.avar >> h.bvar ;
       
     }
};


ostream& operator<<(ostream& o,  hubo< WHAT_COMES, HERE? >& h)
{
  return o << "Hubo[" << h.avar << ',' << h.bvar << "]\n";
}

main()
{
  hubo<double,int> C;
  
  cout << C << '\n';
  
}



When inserting this piece of code [

ostream& operator<<(ostream& o, hubo<double,int>& h)
{
  return o << "Hubo[" << h.avar << ',' << h.bvar << "]\n";
}
 
] instead of something else, gcc-2.1 complains about a missing type conversion
for the ostream& operator<< :

TTest.cc: In function `int  main ()':
TTest.cc:40: type conversion required for type `hubo<double ,int>'

...and what makes things even more strange: when looking at the assembly output
gcc does generate the correct name for operator<< (its the same when defining it
inside the class declaration)

What's wrong?
