We''re using DirectX 8.1. In our "engine" we made some DirectInput components, and this worked just fine. Now it has been a while since we opened the project, and suddenly we get al sorts of errors regarding DirectInput! Some of the errors: error LNK2001: unresolved external symbol _GUID_SysMouse error LNK2001: unresolved external symbol _GUID_SysKeyboard error LNK2001: unresolved external symbol _IID_IDirectInput8A Etc. There was installed a DX9 SDK. We''ve removed this one and installed the DX8.1 SDK again. Could this have anything to do with our problems? Thnx

Are you sure you included the libraries dinput8.lib? But if it worked before you probably did. If it worked before and it doesn''t now, IMO it must be the SDK install..

Yup the lib is included... so it can''t be that, it''s also exactly the same version, that''s why we don''t know whats wrong..

It can''t find the definitions for these functions in the libraries/headers. DirectX 8 libraries are not installed...

Clue... _IDirectInput8A

Reinstalling DX8.1 should have fixed it. Manually uninstall DirectX SDK then reinstall DX8.1 to ensure there are no conflicts.
