I did not realise it before, yes, it does output to console. That is because
BasicConfigurator automatically adds ConsoleAppender to rootLogger. If you
want to avoid that, use PropertyConfigurator instead.

To make the FileAppender append to existing file, configure it with the
Append=true property. Something like this:

log4cplus::helpers::Properties props;
props.setProperty (LOG4CPLUS_TEXT ("Append"), LOG4CPLUS_TEXT ("true"));
props.setProperty (LOG4CPLUS_TEXT ("File"), LOG4CPLUS_TEXT ("logfile.log"));
log4cplus::SharedAppenderPtr fileapp (new log4cplus::FileAppender (props));
