How to get resolve with function redefinition error

I am getting sick    with this error, function Redefinition !!! .
 
 I am building a log file, So that i can keep track of my program memroy allocation and deallocation, to get rid of memory leaks.For that i have build a function template in a Namespace. What i am doing is that , i will  pass Object to this function, this object could be of any type, and getting information about that Object.
 

// MemTrack.h


#ifndef MEMTRACK_H
#define MEMTRACK_H

#include <f32file.h>

namespace MemTracker
{

   void LogInit(const char* logName = NULL)
   {
      //Doing Something with logName
   }

   template<class T>

   void MemLog( T* mVar )
   {
      // Doing something with mVar
   }

};

#endif

Now when i include this template function file in one file it is fine

// Myclass.cpp

#include "MemTrack.h"

MyClass::MyClass()
{
   MemTracker::MemLog(this);  //Working fine , no error
}


But when i include this MemTrack.h file in another file(s) it give me error given below

error LNK2005: "void __cdecl MemTracker::LogInit(char const *)" (?LogInit@MemTracker@@YAXPBD@Z) already defined in SEARCHFILECONTAINER.obj

PLease help me , and tell me how could i able to get access this function in multiple files  : .
