сумасшедшие сообщения об ошибках компилятора C ++ о конструкторе копирования из MinGW32

Я начинающий студент C ++, использую jGRASP и установил MinGW32, потому что мы дистанционно превращаем наши назначения в машину Linux, что помогает гарантировать его правильную работу, моделируя среду Linux в Windows или что-то в этом роде. Для MinGW32 я установил «базовый пакет», а затем вручную выбрал опцию компилятора C ++. В jGRASP я пошел в settings>>PATH/CLASSPATH>>workspace и добавил новый каталог PATH в C:\MinGW\mingw32\bin так что он будет знать, где находится компилятор g ++.

Я получаю эти сумасшедшие сообщения об ошибках при компиляции в jGRASP, которые я не могу понять. Я думаю, что это как-то связано с моим заголовком из-за iostream.

#include <string.h>
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;

Вот сообщения об ошибках компилятора:
