[Insight-users] ITK vs VC++ Conflict in stream files?

[Luis Ibanez]

Hi Martin,

VC++ offers support for both the
old and new iostream libraries.

The traditional library use the header
#include <iostream.h> and do not use
namespaces.

The new library use the header
#include <iostream>   // without ".h"
and use the namespace "std".
So, what previously was "cout" now
is "std::cout".


The selection between both libraries is
not done by checking a check-box in some
menu option as anybody would like but by
the following quite-fuzzy rule:

   "If you include first <iostream.h> the
   traditional iostream library will be used,
   if you include first <iostream> then the
   new libraries will be used."


ITK use the new iostream library and takes
advantage of namespaces.

When you combine ITK code with your project
you have to make sure that an ITK header
is the first to be included.  ITK headers
will make sure that <iostream> is included
before any <iostream.h> you may have in your
project. (or that may exist in the other
libraries used by your project).

Note that in addition to making sure that
an ITK header is included first, you may
want to start using the new headers and
start using namespaces.


Please let us know if you have further questions.


   Thanks


    Luis
