I'm going crazy about this error. I followed the installation guide, making sure that "Additional Include Directories" and "Additional Library Directories" were correct.
When i try to build the ALVARWrapper1.3 project, VS2008 gives me back this issue.
Using VS2008, XNA game studio 3.1, openCV1.0, alvar 1.3.0 and newton 1.53.
Thanks in advance.
