Unexpected end of file error

I hope you can help me, cause I have no idea about what’s going on. I’m having the following error while trying to add Beecrypt library to my project:

fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add ‘#include “stdafx.h”‘ to your source?

Actually I did not forget to add #include “stdafx” to my source. The compiler points the error to be at the end of this .cxx file:

#define BEECRYPT_CXX_DLL_EXPORT

#ifdef HAVE_CONFIG_H
# include "config.h"

Sorry for so much code.
