Loki's SmallObjAllocator of of memory - c++

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

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
