link errors when creating release

Hi. Im trying to create a release version of my program but im getting errors. Im using directx9, c++ in vs.net. And am creating the release by rebuilding the solution in release mode but get the following errors.

Release/Spaceships.exe : fatal error LNK1120: 23 unresolved externals
Anyone know why these errors are apparent when creating the release and not when creating the debug version, and how to get rid? Cheers Stuart [/source]
