I get these errors:

Error 84 error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_system_category(void)" ( ?get_system_category@system@boost@@YAAEBVerror_category@12@XZ)

Error 85 error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_generic_category(void)" ( ?get_generic_category@system@boost@@YAAEBVerror_category@12@XZ)

any tips?

I think the solution is: many boost libraries (those accessing operating system mainly, like filesystem, asio) themselves depend on boost_system library, so you need to link to boost_system library as well. Cheers, Boris thx
