安裝cuda以後再安裝opencv時出現錯誤：

 /data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:120:54: error: ‘NppiGraphcutState’ has not been declared  
      typedef NppStatus (*init_func_t)(NppiSize oSize, NppiGraphcutState** ppStat ^ /data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:135:18: error: ‘NppiGraphcutState’ does not name a type operator NppiGraphcutState*() ^ /data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:141:9: error: ‘NppiGraphcutState’ does not name a type NppiGraphcutState* pState;

cuda8.0較新，opencv-2.4.11較早，要編譯經過須要修改源碼：spa

修改/data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp源碼

將 it

#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) 編譯

改成 opencv

#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000) class

從新編譯便可。module
