which library needs to be linked to, that has implementation code for ErrorInfo::IsA

My env.  Cygwin + Visual Studio.  Windows 7

 

(1)    IsA in ErrorInfo comes from a macro in rtti.hxx

a.       /include/tools/errinfo.hxx

                                                               i.      class
ErrorInfo has as member, macro TYPEINFO() to include 5 methods, including
IsA

b.      /include/tools/rtti.hxx

                                                               i.      This
has macros, including TYPEINFO

c.       Tools/ref/errinf.cxx   ( implementation file, but does not include
implementations for five methods via TYPEINFO macro.

 

(2)    What library needs to be linked to that has  implementation code for
macros in rtti.hxx  for a Win32 Intel platform?

 

 

Here is a test code

//===========================================

#include "stdafx.h"

#include <rtl/ustring.hxx>

#include <include/tools/rtti.hxx>

 

typedef void* (*TypeId)();

class ErrorInfoX

{

private:

    sal_uIntPtr             lUserId;

public:

                            TYPEINFO();

                            ErrorInfoX( sal_uIntPtr lArgUserId ) :

                                lUserId( lArgUserId ){}

    virtual                 ~ErrorInfoX(){}

    sal_uIntPtr             GetErrorCode() const { return lUserId; }

    static ErrorInfoX*       GetErrorInfo(sal_uIntPtr);

};

int main(int argc, char* argv[])

{

                sal_uIntPtr t = 4;

                ErrorInfoX err(t);

                return 0;

}

//linked to lib(s)  itl.lib  ( tools )
