Thanks to everyone who's replied to my previous boost logging question -
still having some issues I'm afraid :S
I've been struggling with boost log for a while now - I got their simple
example writing to a log file
(http://boost-log.sourceforge.net/libs/log/example/doc/tutorial_file.cpp).
However, when I try to copy that code into my own 'Logger' class, I
can't get it to write to the log file. I can see the file `default.log`
get created, but there is nothing in it.
I'm on debian 7 64bit. Everything compiles fine - compile line is:
g++ -o build/Logger.o -c -std=c++11 -Wall -g -O0
-DBOOST_LOG_DYN_LINK -DDEBUG src/Logger.cpp
g++ -o build/logtest build/Logger.o -lboost_log -lboost_log_setup
-lboost_date_time -lboost_thread -lboost_wave -lboost_regex
-lboost_program_options
Here's my code:
`Logger.cpp`
#include "Logger.h"
namespace logging = boost::log;
namespace sinks = boost::log::sinks;
namespace src = boost::log::sources;
namespace expr = boost::log::expressions;
namespace attrs = boost::log::attributes;
namespace keywords = boost::log::keywords;
namespace dhlogging {
Logger::Logger(std::string fileName)
{
initialize(fileName);
}
Logger::Logger(Logger const&)
{
}
Logger::~Logger()
{
}
Logger* Logger::logger_ = nullptr;
Logger* Logger::getInstance(std::string logFile)
{
if ( Logger::logger_ == nullptr ) {
logging::add_file_log( logFile );
logging::core::get()->set_filter
(
logging::trivial::severity >= logging::trivial::info
);
logging::add_common_attributes();
Logger::logger_ = new Logger(logFile);
}
return Logger::logger_;
}
void Logger::initialize(std::string fileName)
{
BOOST_LOG(log_) << "Hello, World!";
BOOST_LOG_SEV(log_, info) << "Hello, World2!";
}
void Logger::logInfo(std::string message)
{
BOOST_LOG_SEV(log_, info) << message;
}
void Logger::logDebug(std::string message)
{
BOOST_LOG_SEV(log_, debug) << message;
}
void Logger::logWarn(std::string message)
{
BOOST_LOG_SEV(log_, warning) << message;
}
void Logger::logError(std::string message)
{
BOOST_LOG_SEV(log_, error) << message;
}
void Logger::logFatal(std::string message)
{
BOOST_LOG_SEV(log_, fatal) << message;
}
}
int main(int, char*[])
{
logging::add_common_attributes();
using namespace logging::trivial;
dhlogging::Logger::getInstance()->logInfo("himom");
return 0;
}
