运行 CPP 文件时出现奇怪的错误

我在 CPP 中创建了一个非常简单的文件，即trash.cpp。使用以下命令运行它：gcc trash.cpp

#include <iostream>
#include <string>

int main() {
    try{
        throw 6;
    }
    catch(int e) {
        std::cout << "Int exception thrown " << std::to_string(e) << std::endl;
    }
}

它显示了非常奇怪的错误。我不知道该搜索什么，所以我在这里发布了我的问题。

粗略地猜测一下，我已经搞砸了我的依赖关系。

请看一看。

[编辑] 另外，另一个粗略的猜测是，也许我需要包含 GCC 外部的库。但不确定。[编辑] 不过这是一个非常愚蠢的问题。

您正在尝试使用C编译器，不是C++要使用 C++ 编译器进行编译，请尝试以下命令：

g++ trash.cpp
