本文介绍如何解决在使用CUDA编译OpenCV过程中遇到的关于NppiGraphcutState未声明的错误。通过简单的源代码修改即可完成修复，使编译顺利进行。

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler -DOPENCV_EXTRA_MODULES_PATH=/usr/opencv/opencv_contrib-3.2.0/modules ..
CFLAGS=-fPIC make

make install

DOPENCV_EXTRA_MODULES_PATH 参数制定额外的模块

-------------------------------------------------------------------------------

如果出现下面错误可按此下修改

/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*()
                  ^

         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)
