[Boost-users] [boost] [log] Link error with trivial logging

Hi, I just built boost 1.43 with the latest version of boost-log included (from boost-log.sourceforge.net). I'm currently using the static, multi-threaded debug libraries from the build: libboost_log-vc80-mt-sgd-1_43.lib At the end of this e-mail you can see the main() from my win32 console application. However, I'm receiving many link errors like the following: libboost_log-vc80-mt-sgd-1_43.lib(trivial.obj) : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_system_category(void)" (?get_system_category@system@boost@@YAABVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'system_category''(void)" (??__Esystem_category@system@boost@@YAXXZ) Any thoughts on what might be causing this? Below is my main(). Thanks! ------------------ #include // For "trivial" logging API #include <iostream> #include <string> void main(int argc, char* argv[]) { BOOST_LOG_TRIVIAL(trace) << "A trace severity message"; BOOST_LOG_TRIVIAL(debug) << "A debug severity message"; BOOST_LOG_TRIVIAL(info) << "An informational severity message"; BOOST_LOG_TRIVIAL(warning) << "A warning severity message"; BOOST_LOG_TRIVIAL(error) << "An error severity message"; BOOST_LOG_TRIVIAL(fatal) << "A fatal severity message"; // keep cmd window open std::cout << "press a key..."; std::string whateva; std::cin >> whateva; } ------------------
