Problem building an application over SFL

Hi all,
I'm trying to build (VC++) a very simple command-line application which
does (or should do ...) following operations:

* login & sign
* login & verify

There is no problem for the login. It works well (verified by means of
debug)
using CSM_AppLogin class (using Free3 CTIL & Crypto++ 3.1).
The problem is signing. When I try to insert instructions into C++ code for
instancing
CSM_MsgToSign class (static instance defining a class variable or dynamic
instance
using a pointer and 'new' keyword), the linker return to me a lot of errors

I can't understand what is wrong!!!
I would appreciate any help!!!
Thank's
Gianluca Ramunno


*******************************************
code causing errors:

CSM_MsgToSign *m_pESSignMsg;  //this definition is in a header file
(escmd.h)
CSM_Buffer *p;
p= new CSM_Buffer(DATA_TO_BE_SIGNED_FILENAME);
m_pESSignMsg= (CSM_MsgToSign *) new CSM_MsgToSign(p);

or

CSM_MsgToSign m_ESSignMsg;


***********************
Some info about building

* Win32 Console application (escmd.exe), Debug Multithread
* from header file (escmd.h):
	#include "sm_api.h"
	#include "sm_AppLogin.h"
* I copied all SFL libraries (.lib and .dll) in a directory under root dir
of my project (setting this
libraries in linker options)
* I set include path in compiler options to all SmimeR1.6 include
directories
