cannot include <fstream>

[nils]

Hi all,

Recently I started migrating a gcc project to Visual Studio C++ (dotnet).
The problem is that I cannot include any iostream header-file:

#include <fstream>
int main (int argc, char * argv)
{
printf("hello world");
return 0;
}

This will result in the following compilation error:

D:\TEMP\dotnettest>cl test.C
Microsoft (R) 32-bit C/C++ Standard Compiler Version 13.10.3077 for 80x86
Copyright (C) Microsoft Corporation 1984-2002. All rights reserved.

test.C
test.C(1) : fatal error C1083: Cannot open include file: 'fstream': No such
file or directory


After investigation, it seems that on my whole system, none of the following
files is available: iostream, fstream, ios. I have installed the .net
framework 1.1, and the CORE-Platform-SDK. The latter should contain the
headerfiles, doesn't it?

==> Do I have a corrupt installation, or is there another problem?

I'd appreciate it, if someone could point me in the right direction,

Thanks,

Nils

This is off topic here, but I'll answer anyway.

The problem is that you don't have Visual C++. You have the .Net Framework
SDK, which indeed comes with a C++ compiler. But this version of the
Microsoft C++ compiler is intended only for creating Managed C++
applications, not for creating normal unmanaged applications. Although it is
capable of doing it (it is, after all, the same compiler that ships with
Visual C++ .Net 2003 Standard Edition) it does not have the ability to
optimise (because it's the Standard Edition) and it doesn't come with an
implementation of the Standard C/C++ Libraries.

So you can't use this compiler for creating 'normal' C++ applications of any
real use. You must either purchase Visual C++ .Net 2003 Standard Edition,
Visual Studio .Net 2003 (any edition), or switch to another free compiler
like g++.

Sorry, it is topical, I was under the impression I was in a different
newsgroup... ^_^

And on a final note, I just saw this download on MSDN:

It's probably what you want.

Thanx Sven! I'l give it a try.
