I have some doubts regarding multiple definitions error in C++. Lets say I definition of have 3 files in a program. One header file and 2 .cpp files. I have included the header file in both the .cpp files. Lets say 1.) I have declared a class in the header file and I have defined the class in each of the .cpp files in exactly the same way.So will this type of implementation cause multiple definitions error?If so,is it because it has two copies of class definitions and the compiler doesn't know which one to take multiple definition of during linkage of two .o files? Can we solve this problem by using extern in header file and defining the class in only one of the files?If we can solve the issue by using this method,do we have to include the .cpp(with class definition) into other .cpp file(with no class definition)? 2.) I have declared and defined a class in header file.Is this case the same as above(mentioned in 1) ? 3.) I have declared a class in the header file and I have defined the class in each of the .cpp files but the definitions(function bodies)differs.So will this type of implementation causes multiple definitions error?If so,How can we solve this problem where the functions bodies differs in the .cpp files? c++ compiler-errors linkage multiple-definition-error share|improve this question asked Sep 20 '13 at 10:07 starkk92 1,05131728 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted 1) You solve this by 'defining the class' in only one cpp file. Why would you want to define it in two files? 2) Don't define things in header files, only declare them. There are exceptions to this rule, for instance inline functions. Also classes themselves can defined more than once (by this I mean declaring the methods and data members of the class, (i.e. writing class XYZ { ... };) but each definition must be identical. The simplest way to achieve this is to define a c Search Username Password Remember Me?

It claims that I have multiple definitions of the constuctor, destructor, and the function UpdateStatus. What usually causes this type of problem? Here is the code for the ServerHandler.hpp and ServerHandler.cpp files. The ServerHandler is derived from a SocketHandler class which has a virtual destructor and two constructors. Thanks for any help, Kevin Nowaczyk Code: #ifndef _SERVERHANDLER_H #define _SERVERHANDLER_H #include
