preprocessor

i am trying to use following pattern.

#ifndef TRACER_H
#include "Tracer.h"
#endif

This is statement is added to each file in the code such that tracer.h is added only once. Still i am getting an error saying multiple objects

Also Tracer.h contains

#ifndef TRACER_H
#define TRACER_H

The preprocessor in C and C++ deserves an entire essay on its own to explore its rich possibilities for obfuscation. It is true that the C++ (and C) preprocessor can be used for a lot of powerful stuff. #ifdefs and #defines are often used to determine platforms, compilers and backends. Manipulating… >>> More
