Hello,
global logger declaration as follows
BOOST_LOG_INLINE_GLOBAL_LOGGER_DEFAULT(mylog_master, boost::log::sources::severity_loggerboost::log::trivial::severity_level);
issues a lots of warnings (see below) pointing to some smart_ptr code.
If anyone could advice - does it look like my problem or something else – it would be greatly appreciated.
Cheers,
Valerii.
