Hello, I am trying to build a boost.log example and I keep getting "undefined references" messages. I searched for how to fix them and came to the conclusion that they are not related to boost.log, but to boost.thread instead. Also, they are coming from a tss.hpp source file found in the boost.thread code. Here is the patebin of the full message: http://pastebin.com/xcsPRVak I am using mingw (gcc 4.7) and boost 1.51 (and codeblocks though I doubt this is relevant). If anyone could please help me I would greatly appreciate it. Best regards, *Alexandru Geana* E-mail address: *alex@alegen.net*
