Hello,
I try to implement that a log entry also logs its line number with
boost::log. If any developer of it reads here, please also consider this a
wishlist item...
I think the best way to add an additional attribute for it
core::get()->add_global_attribute(
  "Line", attributes::mutable_constant(0)
);
in my logger config that is called once at startup.
#define logInfo(methodname, message)                                \
  boost::log::core::get()->get_global_attributes()["Line"].set(__LINE__);
\
  BOOST_LOG_SEV(_log, boost::log::trivial::severity_level::trace) <<
  message
\
Is my idea, but
boostlog.cpp:126:5: error: no member named 'set' in
'boost::log::v2_mt_posix::aux::attribute_set_reference_proxy'
getting the attribute somehow seems to work, but how can I set the value
of the attribute?
Thanks!
