Hi,
Actually the build of my solution gives as result an EXE and some DLLs.
Now, I am creating a new configuration that tranform the DLLs into LIBs.
The following semplified code explains one of the problems that arise
using a solution with a console project that creates the EXE and a lib
project that creates the LIB.
//------------------------------------------------------------------------
// console project
////Main Console file
#include "stdafx.h"
#include "registration.h"
#include <iostream>
int _tmain(int argc, _TCHAR* argv[])
{
std::cout << "# of registrations : [" << GetLen() << "]" << std::endl;
return 0;
}
//------------------------------------------------------------------------
// lib project
//// registration.h
#if !defined(REGISTRATION_H)
#define REGISTRATION_H
#include <set>
size_t GetLen();
bool Registration(int);
#endif //REGISTRATION_H
//// registration.cpp
#include "stdafx.h"
#include "registration.h"
std::set<int> & GetTheSet()
{
static std::set<int> s_set;
return s_set;
}
size_t GetLen()
{
return GetTheSet().size();
}
bool Registration(int id)
{
TRACE("registration of [%d]\n", id);
GetTheSet().insert(id);
return true;
}
namespace
{
const bool bReg1 = Registration(1);
} //!namespace
In this way all work fine and the output is
# of registrations : [1]
But the real case is this:
//------------------------------------------------------------------------
// lib project
////--- registration.h
#if !defined(REGISTRATION_H)
#define REGISTRATION_H
#include <set>
size_t GetLen();
bool Registration(int);
#endif //REGISTRATION_H
////--- registration.cpp
#include "stdafx.h"
#include "registration.h"
std::set<int> & GetTheSet()
{
static std::set<int> s_set;
return s_set;
}
size_t GetLen()
{
return GetTheSet().size();
}
bool Registration(int id)
{
TRACE("registration of [%d]\n", id);
GetTheSet().insert(id);
return true;
}
////--- source1.cpp
#include "stdafx.h"
#include "registration.h"
namespace
{
const bool bReg1 = Registration(1);
} //!namespace
In this way the output is
# of registrations : [0]
I am wondering where is the problem.
TIA.
Marco.
