Ошибка при попытке использовать iostream

[tetramin]

Добрый день.

Я пытался написать программу типа хелловорлд.
Компилятор показывет столько ошибок, что они не помещаются на стандартный вывод.
Думая, что ошибка где-то либо в using namespace std, или в std::cout << ..., я решил попробовать оставить только это:

Код: [Выделить]

#include <iostream>

int main ()
{
return 0;
}

Файл iostream, вместе со всеми, прописанными в нём, есть в /usr/include/c++/4.4/bits
Как я понял в итоге, проблема именно в этих файлах.

Ребята, в чём у меня проблема. Пробовал переустанавливать g++. Не помогает.

[__v1tos]

Код: [Выделить]

sudo apt-get install build-essential
Как компилируете?

[Mam(O)n]

Подозреваю, что компилируешь не с помощью g++. Ибо УМВР.

[tetramin]

build-essential у меня установлен

А компилирую так:

Код: [Выделить]

$ g++ -o hiall hiall.cpp

Я тут ещё попробовал math.h включить:

Что же это такое...?

[Mam(O)n]

Обычно главная ошибка идёт первой в списке, остальное это лишь последствия.

[__v1tos]

А как организовать вывод g++ в файл, что бы увидеть эти ошибки?
Я имею в виду перенаправить вывод в файл

g++ -o hiall hiall.cpp &> 1.txt

И меня такая команда интересовала), спасибо.

Вот начало вывода компилятора:

Всетаки у вас что то не то установлено.

Интересно, как это у тебя заголовочный файл из простого "C" затисался в "C++" каталог? Мне кажется, что тебе придётся грохнуть этот каталог (/usr/include/c++/4.4) полностью и переустановить пакеты, которые подскажет команда dpkg -S /usr/include/c++/4.4

[tetramin]

Снёс каталог /usr/include/c++/4.4
dpkg -S сказала, что нужно поставить libstdc+++-4.4. Поставил.
Попробовал скомпилировать. Ошибок значительно меньше стало. Теперь он просто говорил, что нет файла wchar.h
Я его скопировал из бэкапа папки 4.4 (которую как бы снёс).
Далее он начал ругаться на отсутствие locate.h
С ним я поступил так же, только скопировал его из папки /usr/include/bits
Ошибок стало больше... Решив, что проблема в каталоге /usr/include/bits и ещё, что такое копирование ни к чему хорошему не приведёт я просто написал

Код: [Выделить]

dpkg -S /usr/include/bits На что она мне ответила libc6-dev

Решилась проблема сносом и переустановкой libc6-dev и иже с ней.
Всем спасибо огромное!
