- Microsoft Windows CE Embedded Toolkit for Visual C++ 5.0 
- Microsoft Windows CE Platform Builder, version 2.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

Building an application results in one or more of the following errors:

  

  file.obj : error LNK2001: unresolved external
       symbol "const  type_info::`vftable'" (??_7type_info@@6B@)

  

  file.obj : error LNK2001: unresolved external
       symbol __CxxThrowException

CAUSE
=====

This product does not currently support C++ exception handling or run-time Type
Information.

RESOLUTION
==========

Remove all references to C++ exception handling from the project. These
include:

- /GX switch

- /GR switch

- Use of catch-and-throw keywords

STATUS
======

This behavior is by design.

NOTE: Microsoft Windows CE Toolkit for Visual C++ 6.0 now generates warning C4531
when compiling for Windows CE version 2.10 and later.

MORE INFORMATION

Steps to Reproduce Behavior
---------------------------

     #include <windows.h>

     int WINAPI WinMain(
         HINSTANCE hInstance,
         HINSTANCE hPrevInstance,
         LPTSTR lpCmdLine,
         int nCmdShow )
