Eclipse C++, не собирается Hello world Опции

[Zelepuk]

Сегодня перестал собираться элементарный Хеллоу Ворлд

CODE

#include <iostream>
int main()
{
std::cout<<"Hello, world!\n";
}

Eclipse пишет: Symbol 'cout' could not be resolved

в консоли получаю сообщение

CODE

помогите понять, что стряслось?
