Unresolved Visual C++ Externals

Question

What is the reason for the following unresolved externals?

The Chilkat C++ libs are unmanaged libs, not Managed C++. Notice the "__clrcall" in the error messages. If using Managed C++ in MSVC++, then make sure to wrap the include statements in "pragma unmanaged".

#pragma unmanaged
#include "CkZip.h"
#pragma managed

Alternatively, it is possible to use the Chilkat .NET assembly from Managed C++.
