I UNDERSTAND THAT IT’S UNABLE TO LOCATE THE FUNCTION IN LIBRARIES. BUT THERE WERE NO SHARED OBJECTS GENERATED. HOW CAN RESOLVE THIS?

That is a link error, not a compile error. The command line
you show
says to compile and link, but you didn't specify ant
libraries to link
against so it is not linking against log4cxx.
