1. Do a Clean of your project and delete all the Debug and Release folders.
2. Make sure that you have added all the files into the project correctly.
3. Check that all #include statements have the correct path prefix where necessary.
4. Rebuild the project and correct any errors.
5. Repeat as necessary.

1. Post your query in the correct forum.
2. Format your code properly and put it inside <pre> tags for readability.
