I downloaded Boost.Log from http://www.torjo.com/code/log2.zip to give it a try but ran into two problems immediately (with VC++ 9.0 on Windows XP): * In the (old?) documentation at http://www.torjo.com/log2/doc/html/miscelaneous.html#misc_unicode a macro called BOOST_LOG_DONOT_USE_WCHAR_T is mentioned which can be defined on Windows to use char-based classes instead of wchar_t-based classes. This macro doesn't seem to work though. I couldn't find any other macro I might be able to define to use char-based classes if UNICODE is defined? * The linker is trying to find a library called boost_log-vc90-mt-gd-1_34_1.lib while the filename is really libboost_log-vc90-mt-gd-1_34_1.lib. I renamed the file but got then a linker error (unresolved external symbol "... boost::logging::find_log_by_name(...)"). My code consists only of BOOST_DECLARE_LOG and BOOST_DEFINE_LOG though (thus I would expect I can't make much wrong here :)? Anyone can help? Or is the zip archive I downloaded actually the latest code? Boris
