Problem with DirectInput (DirectInput8Create)

[avrs]

Not sure if it belongs here.

I've started working with DirectX, trying to create a DLL for my game in order to get state,info and use force feedback with my joysticks.

Problem is when I try to create a Direct Input 8 object, the compiler throws the following error:

c:\CPP Projects\DXi\main.cpp|21|undefined reference to `_IID_IDirectInput8A'|

Code: (note I am creating a simple commandline test app for starters)

#define DIRECTINPUT_VERSION 0x0800

#include <windows.h>
#include <windowsx.h>
#include <dinput.h>

#include <iostream.h>

#pragma comment ( lib, "dinput8.lib" )
#pragma comment ( lib, "dxguid.lib" )


LPDIRECTINPUT8 diObject;
LPDIRECTINPUTDEVICE8 joystick;
HRESULT hresult;

int main()
{

// Create a DirectInput device
hresult = DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (VOID**)&diObject, NULL);
//if (hresult == FAILED){cout<<"Error creating Dinput object";system("PAUSE");return 0;}

    system("PAUSE");
    return 0;
}

My IDE is Codeblocks, using newest Windows SDK with DirectX SDK (August 2009)
