So I heard good things about boost log. This claims its existence:
http://boost-log.sourceforge.net/libs/log/doc/html/index.html
This is the tutorial:
If I interpret Andrew's answer correctly, his recommendation is to not use one of the packaged version of Boost.Log but do an SVN checkout from the boost-log SVN repository on SourceForge. I had a quick look at the files in the trunk there and can't find any reference to a v1.
And no, I'm pretty sure that he isn't talking about John Torjo's Boost.Log v2, but a newer version of his Boost.Log that hasn't been packaged for a release yet.
We are using Boost.Log and I'm pretty happy with it so far; your question actually helped me figure out what to do in order to build Boost.Log with 1.46.1...
