And what is your problem? From your letter a little unclear...

Hi guys, I want to define a global logger that can be used in other place. The severity level always be "info". I init the log like this:
#include <cstdlib> #include
#include #include #include #include #include // Here we define our application severity levels. enum severity_level { normal, notification, warning, error, critical };
// The formatting logic for the severity level template< typename CharT, typename TraitsT > inline std::basic_ostream< CharT, TraitsT >& operator<< (std::basic_ostream< CharT, TraitsT >& strm, severity_level lvl) { static const char* const str[] = { "normal", "notification", "warning", "error", "critical" }; if (static_caststd::size_t(lvl) < (sizeof(str) / sizeof(*str))) strm << str[lvl]; else strm << static_cast<int>(lvl); return strm; }
// Global logger declaration BOOST_LOG_INLINE_GLOBAL_LOGGER_DEFAULT(test_lg, boost::log::sources::severity_logger_mt
) void try_logging() { boost::log::sources::severity_logger_mt
& lg = test_lg::get(); // TODO: // always write "info" record, Unknown reason! BOOST_LOG_SEV(lg, normal) << "This is a normal severity record"; BOOST_LOG_SEV(lg, notification) << "This is a notification severity record"; BOOST_LOG_SEV(lg, warning) << "This is a warning severity record"; BOOST_LOG_SEV(lg, error) << "This is a error severity record"; BOOST_LOG_SEV(lg, critical) << "This is a critical severity record"; }
int main(int argc, char* argv[]) { try_logging();
return EXIT_SUCCESS; }
In the log i got this: [2015-01-14 19:00:34.800935] [0x40000300] [info] This is a normal severity re cord [2015-01-14 19:00:34.805935] [0x40000300] [info] This is a notification sever ity record [2015-01-14 19:00:34.806935] [0x40000300] [info] This is a warning severity r ecord [2015-01-14 19:00:34.806935] [0x40000300] [info] This is a error severity rec ord [2015-01-14 19:00:34.806935] [0x40000300] [info] This is a critical severity record
What do i miss? Thank you!
Bill
