If I use boost::log::formatters::attr("TimeStamp") nothing is written to the log file.
That's odd. Could you send a short code sample that shows the problem?
here's the entire program: ---------- #include <boost/log/sources/severity_logger.hpp> #include <boost/log/logging_core.hpp> #include <boost/log/utility/init/to_file.hpp> #include <boost/log/utility/init/common_attributes.hpp> #include <boost/log/formatters/format.hpp> #include <boost/log/formatters/attr.hpp> #include <boost/log/formatters/message.hpp> #include <boost/shared_ptr.hpp> boost::log::sources::severity_logger logger; int main() { boost::log::add_common_attributes(); boost::shared_ptr<boost::log::sinks::synchronous_sink<boost::log::sinks::text_ostream_backend>> sink = boost::log::init_log_to_file("test.txt"); sink->locked_backend()->set_formatter(boost::log::formatters::format("[%1%] %2%") % boost::log::formatters::attr("TimeStamp") % boost::log::formatters::message()); sink->locked_backend()->auto_flush(true); BOOST_LOG(logger) << "message"; } ---------- If I build it with VC++ 9.0 SP1 the file test.txt contains afterwards: [] message Only if I use boost::log::formatters::date_time("TimeStamp") the timestamp is written.
