I'm currently using gcc on RHEL WS v3(Taroon) , and I can't get it to work compile Hello World" .

The program follows .

#include<iostream>

using namespace std;

int main()
{
cout<<"\nHello World";
}


GCC outputs :

In function int main
undefined reference to cout
Use the function first

or something similar .

Any help ?

I'm no C programmer, (and I'm sure one who actually knows what (s)he's talking about will come by shortly, but don't you need a return value (eg return 0)

Also, try some spaces between the characters.

I'll try returning . Anything else ?

The compiler said it doesn't know what is "cout".

You can't use C++ stuff just like that with gcc - it's for compiling C, not C++. If you want to stick with C++, use another compiler - e.g. g++.

Or you can simply change the code and use stdio.h and printf instead.

Google groups search for "cout gcc" for more information.

..and isn't "\n" supposed to go after hello world?

also it is iostream.h not iostream

#include<stdio.h>

int main()
{
printf("\nHello World!\n");
return 0;
}


// Most Modern compilers will also accept

#include<stdio.h>
void main(){printf("\nHello World!\n");}

IMHO, cout would require the library called conio.h (console i/o)
Actually I always automatically put conio et stdio since they are almost always required.
