this is a better example of the error msg. This example does not introduce
extraneous class definitions.
I assume I get unresolved externals.because of a preprocessor directive?
This example linkes with the tools.lib (itl.lib)
//============================================
#include "stdafx.h"
#include <rtl/ustring.hxx>
#include <include/tools/rtti.hxx>
#include <include/tools/errinf.hxx>
int main(int argc, char* argv[])
{
sal_uIntPtr t = 4;
sal_uIntPtr lUserId = 4;
sal_uInt16 nMask = 4;
DynamicErrorInfo err(lUserId,nMask);
return 0;
}
// libs itl.lib ( tools )

Not a library...probably a preprocessor directive?

Subject: 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 )
/*
