Better logging library for C++ [closed]

Question

In our project now we using log4cxx, but those library don't develope some years, also we have some problems with it. Could you advise some library for logging in C++. Library must support multithreade logging, system-log. Also it'll be good if it support logging via << operator. Also lib license must be very democracy - like boost, apache etc Crossplatform support. Must support linux, windows. Better if it support solaris, aix, hp-ux, but it's not necessary.

Answer 1

boost::log is probably the most versatile and well-written logging library I've seen. It's pretty complicated but really genius at the same time. And it does everything you can think of and then some more.

Answer 2

I use the glog library, by google (because I could not install Boost.Log easily). It is both simple to use and powerfull.
