Light weight log lib for c++.
OS version: only for linux. C++ version: c++11 or above.
example: 1: normal case const char* file_path = "test.log"; std::shared_ptrLog4CPP::Formatter file_formatter(new Log4CPP::FileFormatter); std::shared_ptrLog4CPP::FileAppender file_appender(new Log4CPP::FileAppender(file_path)); file_appender->SetFormatter(file_formatter);
const char* module = "test";
std::shared_ptr<Log4CPP::Logger> logger = Log4CPP::Logger::GetLogger(module);
logger->AddAppender(file_appender);
logger->SetLevel(Log4CPP::Level::ALL);
logger->Debug("this debug log.");
logger->Error("this error log.");
logger->Warn("this warn log.");
logger->Info("this info log.");
logger->Fatal("this fatal log.");
2: stream case std::shared_ptrLog4CPP::Formatter console_formatter(new Log4CPP::ConsoleFormatter); std::shared_ptrLog4CPP::Appender console_appender = Log4CPP::ConsoleAppender::Get(); console_appender->SetFormatter(console_formatter);
const char* module = "test";
std::shared_ptr<Log4CPP::Logger> logger = Log4CPP::Logger::GetLogger(module);
logger->AddAppender(console_appender);
logger->SetLevel(Log4CPP::Level::ALL);
int times = 0;
logger->Debug() << "this debug log." << times++ << Log4CPP::Endl;
logger->Error() << "this error log." << times++ << Log4CPP::Endl;
logger->Warn() << "this warn log." << times++ << Log4CPP::Endl;
logger->Info() << "this info log." << times++ << Log4CPP::Endl;
logger->Fatal() << "this fatal log." << times++ << Log4CPP::Endl;
