Dear all,
I am trying to add the security flavor to an application. To achieve this
objective, I wrote the codes to establish a security tunnel between the server
and the client with VC2008. When I build the whole project, there are tens of
similar errors. All of them are as follows:

I am not sure if I forgot some necessary steps before the project setup.
Could you please help me to point out the reason? I really appreciate your
help. Thank you.
Best Regards,
