我正在使用 http://axter.com/ezlogger/index.htm 上提供的EzLogger

我试图从该网站编译简单的示例代码来测试 C++ 记录器。我有一些错误，我发现我可以使用 -fpermissive gcc 选项编译它。现在，我有这样的警告消息：

有没有办法删除警告信息？

我不确定我是否找到了自己问题的答案。

首先，我注意到一篇文章，其中暗示了在较新版本的 C++ 标准中可以更正的内容。当使用多个带有“模板”的基类时，“应该”明确指定方法属于哪个基类。在帖子中，将使用保留字“this”。在我的例子中，函数是静态的，我必须在函数前面加上 get_log_stream，前面带有双冒号的类名。
