AWS. HTTP event logging.

How can I use functions RpGetHttpLogItemCount and RpBuildHttpEventStrings? When i try to compile code i become errors: undefined reference to RpGetHttpLogItemCount' undefined reference to RpBuildHttpEventStrings’ PBuilder generate source with AsExtern.h header, but IMHO it should with RpExtern.h header. How do I configure pbuilder to using HTTP event logging? Maybe I need modify source manualy? :-/ – Regards! Jacek Szumigaj
