i'm going to guess that your app is built to use one version of the C/MFC runtimes and your LibTiff project is setup to use another.
look at the properties for both projects and compare the "C++ / Code Generation / Runtime Library" settings. they should match for the app and the library. if they don't match, you're mixing versions of the C-runtimes, and you'll get lots of multiply-defined symbol errors.
