I get 20 errors after having set up Open CV 2.1 and am going through the set up tutorials again to see if I did something wrong in Visual Studio and Win 7. Took some time to get the libraries linked properly is this something simple that people know how to solve? In the meantime I will continue going over any possible misteps again. Thanks
