使用默认全局记录器的Boost.Log自定义严重性

Question

我尝试使用Boost.Log v1.54设置自定义严重性级别虽然我已经遇到了迄今为​​止在任何Boost.Log stackoverflow条目中都没有提到的问题

以下是代码：

//Within ILogger abstract class header under public:
enum LogLevel
{
    kAll = 0,
    kDebug,
    kInfo,
    kWarning,
    kError,
    kFatal,
    kOff,
};


//Within Logger.cpp
#include "ILogger.h"

BOOST_LOG_INLINE_GLOBAL_LOGGER_DEFAULT( _logger, sources::severity_logger_mt< ILogger::LogLevel > )

以下是错误：
