I have the latest version of stable software (yesterday I made the last emerge rsync).
While I'm trying to compile my programm with icc, I have the following errors:
/usr/include/stdio.h(44): error #77: this declaration has no storage
class or type specifier
__BEGIN_NAMESPACE_STD

and so on.
What's wrong? |

| You have provided insufficient information for anyone to be able to tell you whats wrong. Most likely, your program is just plain incorrect. |

My programms worked perfectly 1 month ago (from that time I haven't compiled my progs). A make emerge rsync every weekend. A have only stable official packages. Only root I compiled with icc by myself (and it works for now).
The following code gives the same beginning of errors:
| Code: |
#include <iostream.h>
main()
{
cout << "Hello, World!\n";
return 0;
}
|
Of course I tried to re-emerge icc.
What extra info do you need  |

I wouldn't be surprised if one month ago you were using a different compiler. :)
Your code should look like:
| Code: |
#include <iostream>
int main()
{
std::cout << "Hello, World!\n";
return 0;
}
|
Which compiles fine with icc 7.0 and g++ 3.2.1 over here. icc is sometimes more strict by default in what it accepts as legal. |

There is another way, setting the std so you don't need to change every cout. (I don't remember it right now, I usually code in C)

Put this in your code | Code: | | using namspace std; |

| Yeah, the problem is that cout isn't visible. Adding a "using namespace std" at file scope will bring the whole standard namespace into the picture, but that might be overkill for larger programs. A "using std::cout" at file scope would just bring in cout. |

System is up-to-date, stable.
g++ compiles
| Code: |
#include <iostream>
int main()
{
std::cout << "Hello, World!\n";
return 0;
}
|
and
| Code: |
using namespace std;
#include <iostream>
int main()
{
cout << "Hello, World!\n";
return 0;
}
|
But this
| Code: |
#include <iostream>
int main()
{
cout << "Hello, World!\n";
return 0;
}
|
doesn't.
icc doesn't work with any code above. Version of icc is 6.0.
It wrties:
| Code: |
test.C(1):error: name must be a namespace name
using namespace std;
^
|
BTW, why not 7.0 in stable release |

Sorry for asking something stupid, but are you sure you compiled your C++ program with icpc and NOT with icc
( the icc is the C, the icpc the C++ compiler from intel!) |

Everything was OK before upgrade at that time. icc worked perfectly with C++ code.
P.S. Anyway, changing to icpc doesn't help. |

cout is undefined there. If icc 6 accepts it, you just got lucky - icc 7 doesn't. That icc 6 is the default choice is probably just an oversight. |
