boost-logging

I'm playing with Boost.Log in boost 1.54.0 to see if it is a viable option for my application. In general, I don't have a problem with the buffering, so I'm not looking to turn on auto_flush or anything... but I noticed that messages that are logged before I call fork() are duplicated, and I'm wondering if it's because they are buffered, the buffer gets duplicated when the process image is copied, and then both processes eventually write their buffer copies to the log file... So basically, I'd like to just do a manual flush on the log, one time only, immediately before I call fork() in order

I'm using Boost(1.55.0) Logging in my C++ application. I have been able to generate log of this format [2014-Jul-15 10:47:26.137959]: <debug> A regular message I want to be able to add source file name and line number where the log is generated. [2014-Jul-15 10:47:26.137959]: <debug> [filename:line_no] A regular message example: [2014-Jul-15 10:47:26.137959]: <debug> [helloworld.cpp : 12] A regular message Source Code: #include <boost/log/core.hpp> #include <boost/log/trivial.hpp> #include <boost/log/expressions.hpp> #include <boost/log/sinks/text_file_backend.hpp> #include <boost/log/utility

I need a global logger that I can use across multiple classes in my project. I want to have logger settings in an ini file. I start following example here and combined it with some suggestions at my earlier question here . My Logger.h is as follows. #pragma once #include <boost/log/common.hpp> #include <boost/log/attributes.hpp> #include <boost/log/utility/setup/from_stream.hpp> #include <boost/regex.hpp> #include <boost/log/expressions.hpp> #include <boost/log/sources/global_logger_storage.hpp> #include <boost/log/support/date_time.hpp> #include <boost/log/trivial.hpp> #include <boost/log

I use the add_file_log() function to initialize a logging sink that stores log records into a text file. When I define several sinks, I have observed: a file is created for each sink. the output is copied to all files. This is my logger: class logger { public: logger(const logger&) =delete; logger(logger&&) =delete; logger& operator=(const logger&) =delete; logger& operator=(logger&&) =delete; static logger& get_instance( const std::string& file, bool console ) { boost::log::register_simple_formatter_factory< boost::log::trivial::severity_level, char >("Severity"); std::string the_format = "[

I am trying to create a Global Logger within my entire application so I can use src::severity_logger_mt< >& lg = my_logger::get(); to get the global logger for different classes (resided in different files) logging. I try to follow the example listed in boost.org (as listed below). But does not seems to work. Did anyone know any example I can follow or what I need to do make if works. Thanks. http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/detailed/sources.html BOOST_LOG_GLOBAL_LOGGER(my_logger, src::severity_logger_mt) // my_logger.h // =========== #include "my_logger.h" BOOST_LOG
