icc compiling problem.

[KBAKEP]

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

and so on.
What's wrong?

[KBAKEP]

Is it problem of glibc or what?
Any suggestions?

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: Select all

#include <iostream.h>

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

Of course I tried to re-emerge icc.

What extra info do you need

[pilla]

can you compile it with g++?

[Zadeh]

I wouldn't be surprised if one month ago you were using a different compiler. :)

Your code should look like:

Code: Select all

#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.

[pilla]

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: Select all

using namspace std;

[Zadeh]

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.

[KBAKEP]

System is up-to-date, stable.
g++ compiles

Code: Select all

#include <iostream>

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

and

Code: Select all

using namespace std;
#include <iostream>

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

But this

Code: Select all

#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: Select all

test.C(1):error: name must be a namespace name
    using namespace std;
                    ^

BTW, why not 7.0 in stable release

[Starfox]

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!)

[KBAKEP]

Everything was OK before upgrade at that time. icc worked perfectly with C++ code.

P.S. Anyway, changing to icpc doesn't help.

[Zadeh]

#include <iostream>

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

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.
