ubuntu装opencv error: ‘NppiGraphcutState‘ has not been declared

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
