【问题描述】：
我在使用 G++ 编译时遇到包含标准 C++ 库文件的问题 这是我尝试编译的代码：
#include <iostream>
int main()
{
return 0;
}
编译时出现错误：
test.cpp:1:20: fatal error: iostream: No such file or directory
#include <iostream>
我不知道为什么... 任何提示将不胜感激，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：这是使用 -v 编译时的日志任何建议都会很棒... :)

【问题讨论】：
-
Win7-64，这就是我要编译的，只是include语句，main方法，然后返回0
-
Win7-64 不附带 g++。 Cygwin，您使用的是什么版本的 g++？明威？其他？该命令是从 DOS 提示符、批处理文件等运行的吗？
-
看看这个 SO 条目。 stackoverflow.com/questions/20307507/…
-
MinGW，它是从一个名为 SCITE 的编辑器中运行的，但它也不能在 CMD Prompt 上运行
