[Dev-C++] #include <ios>

[Bob W. <bo...@ph...>]

I am working my way through Andrews Koenig's and Barbara E. Moo's book
"Accelerated C++, Practical Programming by Example" and have a bit of a
problem with an include file. The program starts:

#include <iomanip>
#include <iostream>
#include <string>
#include <ios>

using std::cin;            using std::setprecision;
using std::cout;          using std::string;
using std::endl;          using std::streamsize;

Unfortunately I get the following error message:

"ios: No such file or directory"

MSVC .NET compiles it just fine. What am I missing?

Regards,

Bob

It is:

#include <iomanip>
#include <iostream>
#include <string>
#ifndef __GNUC__
#include <ios>
#endif

It is not a solution. :) It's something ugly that checks if it is GCC,
and if it isn't it #include <ios> else it doesn't. This assumes that GCC
provides the facilities of <ios> in another header file and that GCC
gives an error for <ios>.

I do not like it. Nope, i don't.

<ios> is part of the standard library. Obviously it has not been
implemented in GCC 2.9.x line. I guess that this has been fixed in the
3.x line, or will be fixed in a future version.

Nothing. <ios> belongs to the ANSI C++ standard. But the standard is
very recent, so something is missing here and there in every compiler. 

As the time passes compilers will be getting more standard compliant.
