Compilation problem with gcc 3.2 on Mandrake 9.0

Compilation problem with gcc 3.2 on Mandrake 9.0

[Patrick H. E. Foubet]

Hi every body,

I work with the GNU gcc v 3.2 on Mandrake 9.0
For information, when I execute "gcc -v" I get :
Reading specs from /usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.2/specs
Configured with: ../configure --prefix=/usr --libdir=/usr/lib 
--with-slibdir=/lib --mandir=/usr/share/man --infodir=/usr/share/info 
--enable-shared --enable-threads=posix --disable-checking 
--enable-long-long --enable-__cxa_atexit 
--enable-languages=c,c++,ada,f77,objc,java 
--host=i586-mandrake-linux-gnu --with-system-zlib
Thread model: posix
gcc version 3.2 (Mandrake Linux 9.0 3.2-1mdk)

I think that there are some problems but I want to be sure that it is 
not in your part.
For instance, consider a simple program (hello.cpp) like this :

#include <iostream>
int main(void)
{
    cout << "Hello World !" << endl;
}

when I compile il with "g++ hello.cpp" I get :

hello.cpp: In function `int main()':
hello.cpp:6: `cout' undeclared (first use this function)
hello.cpp:6: (Each undeclared identifier is reported only once for each 
function it appears in.)
hello.cpp:6: `endl' undeclared (first use this function)

If I replace <iostream> by <iostream.h> it works but I get :

In file included from /usr/include/c++/3.2/backward/iostream.h:31,
                  from hello.cpp:2:
/usr/include/c++/3.2/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.

Is it normal ?

Merry Christmas and best regards.

Patrick

This is a FAQ.  
The C++ standard library is put in the namespace std.  Please,
consider a recent book on C++ like the third edition of "The C++
Programming Language" by B. Stroustrup.

Yes.
