I'm having problem while trying to use boost log. I'm getting following error message:

I'm not really sure what is wrong. The libraries are there, the linker finds them. Just not symbols in them. Any tips?
Ok, figured it out. Problem was, that boost was compiled with _WIN32_WINNT 0x0601 while I was building with 0x0501. Just changed mine to 0x0601 as well and it linked fine.
But this program or application you created works in windows 7 or more. It does not supports for Windows XP.
If you want to create application that supports for windows XP, then you can use BOOST 1.58 version. This version is last which supports from Windows XP. Then later versions supports more than windows XP (i.e.)From vista only.
