Hi,

I've just downloaded digital mars and have started to play around with it.
So far I like what I see except that it seems that I have to use the
old-style way of including headers. So, for example:

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

compiles whereas:

#include <iostream>
using namespace std;
int main() {
    cout << "hello\n";
    return 0;
}

does not. The compiler says 'unable to open input file iostream'. I'm
wondering if dm simply does not support the newer way of including files or
if the problem lies in my setup. I'm using dm version 8.26n on windows 2000.

Thanks in advance,

Richard.

That's because that file does not yet exist in the package!

Surely it's the same file? As I understand it you can include iostream by
typing "#include <iostream.h>" but the proper way of doing it is by typing
"#include <iostream>".  Whichever method you use you're still talking about
the same header file aren't you??

AFAIK yes.
iostream could just #include <iostream.h>...

Actually, I've just created an 'iostream' that does just that ;o)

However, I've just realised this still doesn't give me the 'std' namespace -
but that's too much like hardwork to sort out right now so maybe I'll forget
about namespaces for now...

The compiler doesn't seem to support namespaces either?!

#include <iostream>

int main()
{
    std::cout << "Hello World!" << std::endl;

    return 0;
}

This produces errors, when compiled, even if iostream.h is used instead...

Can this be true?? I thought this compiler was good!

It's supposed to be defined in the std namespace though isn't it?

So this compiler is not ANSI/ISO compliant in the least bit? According to
ANSI/ISO compliance, cout is defined int the std namespace. In practice,
this means that most modern, compliant code cannot be compiled with this
compiler. That's a shame.

I think the compiler does support namespaces (in the sense that you can
create your own namespaces) but the standard c++ headers have not been
placed in the std namespace as they are supposed to be. That's why you can't
use std::cout.

Richard.

Correct to some extend. Walter is working on this.

 but the standard c++ headers have not been placed in the std namespace as they
 are supposed to be. That's why you can't use std::cout.

Correct.
