推荐答案

您永远不会声明符号 dir 。这条消息怎么可能不清楚？声明变量或类型成员。如果您已经具有相同名称的变量或成员的声明并且仍然存在此错误，则表示它是在您尝试使用此对象的内容中不可见的范围内完成的。 C ++范围和可见性规则非常简单，您可以立即学习它们。请做，否则你几乎不能走远。



请问，这个问题需要纯文本信息：一些代码示例+错误信息。以正确格式的文本形式在您的问题中提供此信息是否如此困难？毕竟，你有一个剪贴板。屏幕截图非常不方便。

You never declare the symbol dir. How can this message be unclear? Declare the variable or a type member. If you already have the declaration of the variable or member under the same name and still have this error, it means it is done in the scope not visible in the content you are trying to use this object. C++ scope and visibility rules are extremely simple, you can learn them in no time. Please do, otherwise you hardly can go far.

And please, this question requires pure textual information: some code sample + error information. Was it so difficult to provide this information in your question in the form of properly formatted text? After all, you have a clipboard. A screenshot is extremely inconvenient.

请注意 opendir 是一个 Linux 函数（参见 opendir手册页 [ ^ ]）。请查看此Stack Overflow问题以获取建议：Microsoft Visual Studio：opendir（）和readdir（），怎么样？ [ ^ ]。

Please note opendir is a Linux function (see opendir man page[^]). Look at this Stack Overflow question for suggestions: "Microsoft Visual Studio: opendir() and readdir(), how?"[^].
