XviD compile error - (portab.h: fatal error C1189)

[snopa]

Hello everybody,

I'm trying to compile XVID in Visual C++ and I put the simple call:
- xvid_encore(etc)

In the document header:
#include "xvid\xvid.h"
#include "xvid\encoder.h"

The next error message appears to me;

portab.h: fatal error C1189: #error : You are trying to compile XviD without defining address bus size.

Someone can help me?
