You have managed toexpose a problem with the forum software making it impossible to reply with most browsers.
If you are linking in Visual Studio, a buildlog might be useful.
I assume you are invoking IPP intentionally. It looks like you may be mixing up cdecl and the ancient stdcall (with @24) references.
If the question is specific to IPP, the IPP forum may be more helpful.
