Question

在使用G ++编译时，我遇到了包括标准C ++库文件在内的问题这是我试图编译的代码：

#include <iostream>
int main()
{
  return 0;
}

编译时我得到一个错误：

test.cpp:1:20: fatal error: iostream: No such file or directory
#include <iostream>

我无法弄清楚为什么...... 任何提示都将不胜感激，谢谢。

编辑：这是我用来编译的命令

g ++ -pedantic -Wall -Wextra -std = c ++ 11 test.cpp -o test

编辑：这是用-v编译的日志。任何建议都会很棒...... :)

我可以通过重新安装MinGW来解决这个问题

不能包含使用GCC-G ++的标准C ++库文件
