自ビルドしたNeoが使えないです

extern const AVSFunction Device_filters[] = {
{ "OnCPU", BUILTIN_FUNC_PREFIX, "c[num_prefetch]i", OnDevice::Create, (void*)DEV_TYPE_CPU },
{ "OnCUDA", BUILTIN_FUNC_PREFIX, "c[num_prefetch]i[device_index]i", OnDevice::Create, (void*)DEV_TYPE_CUDA },
{ "OnCPU", BUILTIN_FUNC_PREFIX, "n", OnDevice::Create, (void*)DEV_TYPE_CPU },
{ "OnCUDA", BUILTIN_FUNC_PREFIX, "n[device_index]i", OnDevice::Create, (void*)DEV_TYPE_CUDA },
{ 0 }
};

ここの "n" って文字がunknownだと怒られる
