Cant compile with Error 1 error LNK2001: unresolved external symbol Nothing

[Nenad Vujic]

Hello,
i am trying to compile uMod latest or older version [OTM]
i compile with
uMod_DX9_dll_DIRECT_INJECTION.def it gives me error unresolved external symbol Nothing
and with
uMod_DX9_dll_HOOK_INJECTION.def it gives me error unresolved external symbol InstallHook and RemoveHook

if i remove Nothing from uMod_DX9_dll_DIRECT_INJECTION.def it compiles but uMod tool gives me error unable to find function Nothing

Any help?
Thanks in advance
