I try to use the static library in my MFC project, but I get the following linker error:

The name of the static library is kriptolib.lib, it is my own product. He does not use MFC. I can’t understand what the problem is.
The problem occurs when I try to create a new object from criptolib.
theApp.encryption = new RC4();
If I comment on the line below, the compiler does not detect any errors.
