This builds fine for me:

#include <iostream>

#include "itkLineConstIterator.h"

int main(int argc, char *argv[])
{
  typedef itk::Image<unsigned char, 2> ImageType;
  ImageType::Pointer image = ImageType::New();

  typedef itk::LineConstIterator< ImageType > LineIteratorType;
  ImageType::IndexType point0;
  point0[0] = 170.91;
  point0[1] = 144.438;

  ImageType::IndexType point1;
  point1[0] = 170.91;
  point1[1] = 450.510;

  LineIteratorType it( image, point0, point1);
  it.GoToBegin();
  while (!it.IsAtEnd())
    {
    std::cout << (float)it.Get() << std::endl;
    ++it;
    }

  return EXIT_SUCCESS;
}
