Compiler appears to complain about a missing copy constructor that is actually defined.
Compiles fine on IRIX 6.5.x MIPSpro 7.3.1.1m compiler.

==== Place in TriangleIterator.hpp ====

#ifndef _GFX_TRIANGLEITERATOR_HPP_
#define _GFX_TRIANGLEITERATOR_HPP_

#include <stdexcept>

typedef unsigned int Int;

class Triangle
{
public:
  Triangle() {}
  Triangle(const Triangle& t);
  virtual ~Triangle() {}
};

class TriangleContainer;

class TriangleIterator 
	: public std::iterator<std::input_iterator_tag, Triangle, Int, const Triangle*, const Triangle&>
{
public:
  explicit TriangleIterator(const TriangleIterator& iter);
  virtual ~TriangleIterator();

  TriangleIterator(const TriangleContainer& triangles, bool begin);
  
};

#endif



===== Place in TriangleContainer.hpp ===========


#ifndef _GFX_TRIANGLECONTAINER_HPP_
#define _GFX_TRIANGLECONTAINER_HPP_

class TriangleIterator;

class TriangleContainer
{
public:
  typedef TriangleIterator const_iterator;

  virtual const_iterator begin() const;
  
protected:

  friend class TriangleIterator;
};

#endif



======== Place in TriangleContainer.cpp ===========

#include "TriangleContainer.hpp"
#include "TriangleIterator.hpp"

TriangleContainer::const_iterator TriangleContainer::begin() const
{
	return TriangleIterator(*this, true); 
}



====== Issue compile command: =========

g++ -c TriangleContainer.cpp -o TriangleContainer.o
TriangleContainer.cpp: In method `TriangleIterator 
TriangleContainer::begin () const':
TriangleContainer.cpp:6: no matching function for call to 
`TriangleIterator::TriangleIterator (TriangleIterator)'
