我正在使用Boost-Log 2.0,它与版本1存在一些差异,我很难输出"Severity"属性.
我正在使用"Boost.Format-style"格式化程序
"%TimeStamp% [%Uptime%] (%LineID%) <%Severity%>: %Message%"
TimeStamp,LineID和Message是common_attributes.Uptime是我添加的属性attrs::timer().我认为Severity在使用时会自动添加severity_logger,但显然不是,这是我的问题.我得到空的严重性,例如:
2013-Apr-06 19:21:52.408974 [00:00:00.001337] (3) <>: A warning severity message
注意空<>.我试图添加严重性,register_simple_formatter_factory但后来我得到编译器错误:
error: no matching function for call to ‘register_simple_formatter_factory(const char [9])’
而且我不明白为什么.
