boost-log

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

On upgrading to boost 1.60.0 some applications are failing to link with boost log when built with MinGw 4.9.2 on Windows 7. I get the following linker errors: undefined reference to `_imp___ZN5boost3log9v2_mt_nt67trivial6logger3getEv' undefined reference to `_imp___ZN5boost3log9v2_mt_nt63aux15stream_providerIcE17allocate_compoundERNS1_6recordE' undefined reference to `_imp___ZN5boost3log9v2_mt_nt63aux25unhandled_exception_countEv' undefined reference to `_imp___ZN5boost3log9v2_mt_nt611record_view11public_data7destroyEPKS3_' bad reloc address 0x1 in section `.text$

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 = "[

While using Boost.Log, I am trying to keep my TimeStamp formatter such as: logging::add_file_log ( keywords::file_name = "my.log", keywords::format = ( expr::stream << expr::format_date_time< boost::posix_time::ptime >("TimeStamp", "%Y-%m-%d %H:%M:%S") << "," << expr::attr< int >("Line") << " " << expr::attr< std::string >("File") << " " << logging::trivial::severity << " - " << expr::smessage ) ); It is said that I cannot use the other form of formatter since I'll have much difficulties turning "TimeStamp" into my custom format: static void my_formatter(logging::record_view const& rec,

I am trying to use the new Boost.Log library in a project I am working on. The project is built with CMake. I am receiving link errors claiming that the linker has come across undefined references to Boost.Log Linking CXX executable main CMakeFiles/main.dir/main.cpp.o: In function `main': main.cpp:(.text+0x30): undefined reference to `boost::log::v2s_mt_posix::trivial::logger::get()' I have a simple hello world test that fails with these errors. If I am linking against the Boost.Log libraries what would cause it to generate an undefined reference error? main.cpp: #include <boost/log/trivial

I'm using Boost-Log 2.0, which has some differences from version 1, and I have a hard time outputting the "Severity" attribute. I'm using the "Boost.Format-style" formatters "%TimeStamp% [%Uptime%] (%LineID%) <%Severity%>: %Message%" TimeStamp , LineID , and Message are common_attributes . Uptime is an attribute I added using attrs::timer() . I thought that Severity was automatically added when using severity_logger , but apparently it isn't and that's my problem. I get empty severities, eg: 2013-Apr-06 19:21:52.408974 [00:00:00.001337] (3) <>: A warning severity message Notice the empty <> .
