problem on linking sqlite to xcode 4

I use fmdatabase for my sqlite project, i add lib to my frameworks and could run on simulator, when i wa开发者_Go百科nt to release my project have a linking error. does anyone know how to fix it? Thanks

Look at capital and small letters. Device is different from Simulator in that point. Your letters must be the same. Also try to read error message, it helps a lot. It is also possible that you have different SDK version(iOS) on device and Simulator. Check it.
