A small C++ logging libraryGetting StartedYou will need the boost library (at least 1.34.0) you can find it here.

For help on how to compile boost: Getting Started.

Once boost is compiled, you can give it a try by compiling the examples

Download the loglite using svn. Go into the folder gcc and follow the instructions supplied in the README file.

You're done.

Much more is possible thanks to Boost.IOStreams and Boost.Asio.

Look at logging_test_iostream.cpp for an example of log compressed on the fly Look at logging_test_iostream_client.cpp and logging_test_iostream_server.cpp for logging through a network.

More examples in the trunk
