/home/usrname/OpenCV-3.0.0/modules/cudalegacy/src/graphcuts.cpp:120:54: error: ‘NppiGraphcutState’
has not been declared
typedef NppStatus (*init_func_t)(NppiSize oSize, NppiGraphcutState** ppStat
^
/home/usrname/opencv-3.0.0/modules/cudalegacy/src/graphcuts.cpp:135:18: error: ‘NppiGraphcutState’ does not name a type
operator NppiGraphcutState*()

/home/usrname/opencv-3.0.0/modules/cudalegacy/src/graphcuts.cpp:141:9: error: ‘NppiGraphcutState’ does not name a type
NppiGraphcutState* pState;
解决方案：需要修改一处源码：
在graphcuts.cpp中将
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)
改为
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)
