This means you are effectivelly disabling the macro because it will expand
into empty space. Also "the error"? What error do you mean? Have you included
<log4cplus/loggingmacros.h>?

Just today somebody has reported a bug that BasicConfigurator uses wrong name
for the ConsoleAppender (it should be "log4cplus::ConsoleAppender") and thus
this will not set up output to console correctly with 1.0.3-RC5. It is fixed
in Subversion repository and it will fixed in the next RC. I will probably
roll RC6 this weekend.
