Problem Compiling...

[mangeli]

Ok, I'm a newbie, so bear with me...
I'm running Mandrake 9.1.

I picked up a copy of Sams Teach yourself C++ in 21 days, and I created my hello.cpp file.

#include <iostream>

int main()
{
     std::cout << "Hello World!\n";
     return 0;
}

I know, its the most basic thing all programmers learn to do.

However, when I run

#: gcc -o hello hello.cpp

I get errors and nothing is created.

In function `main' :
: undefined reference to `std::cout'

and it goes from there....

just remove the std:: infront of cout, and everything should be fine.

So the code would be:

#include <iostream>

int main()
{
    cout << "Hello world\n";
    return  0;
}

I alread tried that. I get

`cout' undeclaired (first use this function)

Redhead: He actually must put "std::" before it since he isn't
using the namespace "std".

Mangeli: I suggest you include <iostream.h> instead of
<iostream>, It might be that you still have the old iostream.

[mangeli]

when I try iostream.h I get an error about that being the old version of GCC (I'm running 3.2.2)

Try 'g++' instead of 'gcc', that might work.

That got it.

Thanks.
