Show the code and/or the properties file you are using.

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));

props.setProperty (LOG4CPLUS_TEXT ("File"), LOG4CPLUS_TEXT ("logfile.log"));

props.setProperty (LOG4CPLUS_TEXT ("PatternLayout"),LOG4CPLUS_TEXT ("%c"));

log4cplus::Layout pattlayout = new log4cplus::PatternLayout(props);

Well, the documentation is not that good as it should be. If in doubt, look
into the code :)

What part of my example is not clear?

Oh, I can see what you mean. Sorry. Try to take a look at the tests in tests
directory. There is even a patternlayout_test.
