Remove one of the typedef struct node. –Eregrith Jun 12 '15 at 8:20 1 Or even better yet: Move your definition of your struct node and its typedefto another file dedicated to doing that. –Eregrith Jun 12 '15 at 8:21 You might want to show the relevant lines from those

My header file looks like: #ifndef _MyQueue_h #define _MyQueue_h using namespace std; template class MyQueue { public: MyQueue(); ~MyQueue(); void enqueue(T element); T peek(); void dequeue(); int size(); bool empty(); private: int count; stack stk1; stack stk2; }; # include "MyQueue.cpp" # endif And my cpp (implementation) file looks like: #include #include "MyQueue.h" using namespace std; http://stackoverflow.com/questions/19965300/c-error-message-redefinition-of-functions template MyQueue::MyQueue() { count = 0; } template MyQueue::~ MyQueue() { } template void MyQueue::enqueue(T element) { stk1.push(element); count ++; } (other functions omitted). However, using Xcode 4.5, it keeps saying that my functions (MyQueue, ~MyQueue, enqueue, peek, etc.) are redefined. Can anyone help me to clarify where have I redefined them? Thank you c++ class stack queue redefinition share|improve this question asked Nov 13 '13 at 22:02 Hayden Coyle 11112 2 You should never include a source file (i.e files ending in .cpp, .cc, or .C). Also, make sure to include the header file in which your stack is defined, unless you are using the STL stack. –noobProgrammer Nov 13 '13 at 22:07 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote You're trying something which I really don't like. It's a pretence. Remove #include "MyQueue.cpp", replace it with the content of MyQueue.cpp, delete the file MyQueue.cpp. Now everything will work. You are trying to pretend the template code can be split into header file and implementation file. But because it can't you have to cheat by including the implementation file in the header file. It's less confusing if you don't cheat o

Any help is really appreciated, thanks, John 12-01-2009 #2 hk_mp5kpdw View Profile View Forum Posts Registered User Join Date Jan 2002 Location Northern Virginia/Washington DC Metropolitan Area Posts 3,817 You probably have an object (show_all_passengers) error redefinition of in a header somewhere that's getting included multiple times which to the compilers point of view is attempting to have several different objects with the same name created (this is bad). If this is the case, remove the objects declaration from the header (or at least make it "extern" within the header) and make sure an actual declaration exists only in a single source file. ... or something along those lines.
