Cannot understand what linker is complaining about

When compiling my project that uses boost logging library, I am getting following linker error.
LNK2001 unresolved external symbol "public: static class
boost::log::v2s_mt_nt6::sources::severity_logger_mt __cdecl
my_logger::construct_logger(void)"
(?construct_logger@my_logger@@SA?AV?$severity_logger_mt@W4severity_level@trivial@v2s_mt_nt6@log@boost@@@sources@v2s_mt_nt6@log@boost@@XZ)
I don't know how to read this error message with mangled function names. Can anyone tell me in human readable way what function it cannot find?

i have read the links provided and it does not help me at all as those answers are very generic. Please help me understand this specific scenario.

In short: have you been linking against the correct boost library (.lib) files?

Your linker is more informative than most. The first line tells you the linker is trying to find a symbol (something with a name, such as a function) needed in order for your program to run, but not finding it. The second line has unmangled information about that missing symbol - it is a function namedmy_logger::construct_logger(void)(thevoidmeans it is called with no arguments) and has a return type ofboost::log::v2s_mt_nt6::sources::severity_logger_mt. The__cdeclis compiler/system specific, but describes the calling convention of your function. The rest is the mangled name.

Googling "boost log unresolved external symbol" leads to https://www.boost.org/doc/libs/1_59_0/libs/log/doc/html/log/rationale/namespace_mangling.html (first, highlighted hit) which describes BOOST_LOG_DYN_LINK.
This incidentally also the most frequent answer on SO: https://stackoverflow.com/search?tab=votes&q=%5bboost-log%5d%20linker
However ABI issues can play a role, see e.g. Unresolved external when using boost log
