I have some doubts about your question: are you using the named_acope
attribute yet? If that is the case, just needs to include some other tags
like the next example
> boost::log::keywords::format = "%n (%f : %l)")
This line would print something like: "void main() (main.cpp : 25)"
If that is not the case, please, could you be more specific about how did
you set your logger? I have been struggling the past weeks with that and I
may help you. Best regards!
