[enb141]

Hi guys I'm trying to compile the nJoy plugin, I just got all files in http://dolphin-emu.googlecode.com/svn/trunk/ (3173) but when I try to compile nJoy_SDL it gives me this error
[color=#FF0000]
Error 5 fatal error C1083: Cannot open include file: 'dinput.h': No such file or directory d:\tests\dolphin\3173\source\plugins\plugin_njoy_sdl\src\njoy.h 68 Plugin_nJoy_SDL[/color]

I'm using Visual Studio 2008 Windows XP SP3

and when I try to compile nJoy_SDL_Test in x64 it gives me this error:
