Loki's SmallObjAllocator of of memory

Question

#include "stdafx.h"                            //In order to use Visual C++

#include <iostream>
#include <Loki\SmallObj.h>                    //The header file to manage
                                              // smalls objects allocator

class MySmallObj : public Loki::SmallObjAllocator    //inherit from the base
                                                     //class SmallObjAllocator 
{
public:
    MySmallObj():SmallObjAllocator(sizeof(char), sizeof(long),0){};
};

int _tmain(int argc, _TCHAR* argv[])
{
    MySmallObj * premier = new MySmallObj;                                                      //declaring my object derived from smallobjallcator
    char * myChar = static_cast<char*>( premier->Allocate(1, true));            //calling allocate from my object and conveting the void pointer to char*
    premier.Deallocate(myChar, 1);

    return 0;
}

The loki library uses essentially generic programming in c++ I have got the code up there using Small object allocator of memory(Loki::SmallObjAllocator) I m using visual c++ 2010

I get those errors:

  >  MyLoki.cpp
1>MyLoki.obj : error LNK2019: unresolved external symbol "public: void __thiscall Loki::SmallObjAllocator::Deallocate(void *,unsigned int)" (?Deallocate@SmallObjAllocator@Loki@@QAEXPAXI@Z) referenced in function _wmain

Answer 1

I have founded an answer to my first question.

#include "stdafx.h"                            //In order to use Visual C++

#include <iostream>
#include <Loki\SmallObj.h>                    //The header file to manage
                                              // smalls objects allocator

class MySmallObj : public Loki::SmallObjAllocator    //inherit from the base
                                                     //class SmallObjAllocator
{
public:
    MySmallObj():SmallObjAllocator(sizeof(char), sizeof(long),1){};  //the chunkSize < maxObjsize
};
int _tmain(int argc, _TCHAR* argv[])
{
    MySmallObj * premier = new MySmallObj;                                                      //declaring my object derived from smallobjallcator
    char * myChar = static_cast<char*>( premier->Allocate(1, true));            //calling allocate from my object and conveting the void pointer to char*
    premier->Deallocate(myChar, 1);

    return 0;
}

the errors of multiple

unresolved external symbol

are because of SmallObj.cpp , of Loki that was not included to the project

for example of Loki::SmallObjAllocator, Loki::SmallObject here
