Axter EzLogger - 如何删除警告或错误消息？ i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1

Question

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

我尝试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，我收到这样的警告消息：

In file included from src/ezlogger_headers.hpp:18,
src/ezlogger.hpp: In static member function ‘static void axter::ezlogger<EZLOGGER_OUTPUT_POLICY, EZLOGGER_FORMAT_POLICY, EZLOGGER_VERBOSITY_LEVEL_POLICY>::log_out(const char*, int, const char*, axter::ext_data, bool, const T&)’:

有没有办法删除警告信息？

Answer 1

我不确定我是否找到了自己问题的答案。

首先，我注意到post，它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，方法“应该”明确指定该方法属于哪个基类。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。
