错误：/home/usrname/opencv-3.1.0/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-3.1.0/modules/cudalegacy/src/graphcuts.cpp:135:18: error: ‘NppiGraphcutState‘ does not name a type
operator NppiGraphcutState*()
^
/home/usrname/opencv-3.1.0/modules/cudalegacy/src/graphcuts.cpp:141:9: error: ‘NppiGraphcutState‘ does not name a type
NppiGraphcutState* pState;
.......
解决方案：
进入opencv-3.1.0/modules/cudalegacy/src/目录，修改graphcuts.cpp文件，将：
#include "precomp.hpp"
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)
改为
#include "precomp.hpp"
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)
然后make编译就可以了
