The log file remains empty . What's wrong?

For performance reasons, files are not flushed immediately. Try any of the following methods:

my_logger->flush_on(spdlog::level::info);      // my_logger will flush when "info" or higher message is logged
spdlog::flush_on(spdlog::level::info);         // all loggers will flush when "info" or higher message is logged on all loggers
spdlog::flush_every(std::chrono::seconds(5));  // flush periodically every 5 seconds (caution: must be _mt logger)

See the flush policy for details.
