GCC

22 Jul 2004

      Hi there!

I am running a SuSE Linux 9.0 machine.
These are the header files of the C++ pr0gram I am
trying to compile.

Header of the file Array.h 

#ifndef _ARRAY_H_
#define _ARRAY_H_

#include <stdio.h>

template <class T>
class Array
{
...
}
#endif 

Header of the file Array.cc 

#include "Array.h"

template <class T>
Array<T> &Array<T>::operator=(const Array<T> &other)
{
...
}

Header of the file Array_templ_Main.cc 

#include <iostream.h>

#include "Array.h"

int main()
{
...
}

The compilation command with GCC is as follows:

ntienjem@njueya:~/examples> gcc -o mar Array.cc
Array_templ_main.cc

I got the following errors:

In file included from
/usr/include/g++/backward/iostream.h:31,
                 from Array_templ_main.cc:1:
/usr/include/g++/backward/backward_warning.h:32:2:
warning: #warning This file includes at least one
deprecated or antiquated header. Please consider using
one of the 32 headers found in section 17.4.1.2 of the
C++ standard. Examples include substituting the <X>
header for the <X.h> header for C++ includes, or
<sstream> instead of the deprecated header
<strstream.h>. To disable this warning use
-Wno-deprecated.

QUESTION:

Does someone know how to solve this problem?

Thanks so much in advance for your valuable hints.
