Compiler Error: Undefined References; Codeblocks

[h3llpunk]

Hi I get the common Undefined References error in CodeBlocks I am pretty sure The code is right.

case WM_PAINT:
		{
            BITMAP bm;
			PAINTSTRUCT ps;

			HDC hdc = BeginPaint(hwnd, &ps);

			HDC hdcMem = CreateCompatibleDC(hdc);
			HBITMAP hbmOld = (HBITMAP)SelectObject(hdcMem, g_hbmAnime);

			GetObject(g_hbmAnime, sizeof(bm), &bm);

			BitBlt(hdc, 150, 100, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

			SelectObject(hdcMem, hbmOld);
			DeleteDC(hdcMem);

			EndPaint(hwnd, &ps);
		}

compiler error:

You need to link "gdi32.dll" into your project :)
