Description Reaz 2003-05-16 09:22:44 UTC
Hear is a small program which give the following error when compiling under
redhat 9.0 but with redhat 7.0 it work fine when  using g++ or gcc
*************************************************************
#include <iostream>
#include<fstream>
class Customer
{
private:
	char mobileNo[11];
	char name [25];
	char dateofBirth [9];
	char billingAddress [51];
	char city [25];
	char phoneNo [11];
	float amountOutstanding;
public:
	void print()
	{
	        cout << endl << "Mobile Phone number: " ;
                cout << mobileNo << endl;
		cout << "Name: ";
		cout << name << endl;

that error

************************************************************************an 
another small one

#include <iostream.h>
int main()
{
	cout << "hello";
	return 0;
}

************************************************************************it give 
the following error

In file included from /usr/include/c++/3.2.2/backward/iostream.h:31,

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.
But when compiling this one
#include <iostream.>
int main()
{
	cout << "hello";
	return 0;
}
the following error is given

i have update the following package
glibc-2.3.2-27.9.i386.rpm
glibc-2.3.2-27.9.i686.rpm
glibc-2.3.2-27.9.src.rpm

with out any result

any one can help me

Comment 1 Jakub Jelinek 2003-06-19 13:39:49 UTC
GCC 3.x attempts to conform to ISO C++ 98, so you cannot throw at it random
non-standard code and expect it to compile.
The message printed in backward/backward_warning.h is not an error, just
a warning which tells you you should convert your program to ISO C++ 98
(which means either replacing cout in your code with std::cout, or adding
using std::cout;
or
using namespace std;
).
no match for `std::basic_ostream<char, std::char_traits<char> >& < <unknown type>' operator
error is because you wrote <endl, instead of <<endl on line 61.
