ubuntu16.04下CUDA9.1+OPENCV3.1安裝記錄

之前總是分開裝CUDA和nvidia驅動，時常導致各種bug，於是這次一怒之下使用cuda官網的deb方式安裝，同時裝好cuda和nvidia驅動，但是cuda裝的卻是最新版本9.1,還沒裝opencv之前就想到一定會出現各種bug……

 一開始選擇的是opencv2.4.13,結果cmake報錯：

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_nppi_LIBRARY (ADVANCED)
linked by target "opencv_cudev" in directory D:/Cproject/opencv/opencv/sources/modules/cudev

按http://blog.csdn.net/u014613745/article/details/78310916  的解決方法確實可以解決這個cmake的問題。

然而！

make的時候卻一直碰到no rule to target “……libnppist.so”的問題，嘗試了一晚都解決不了。

於是最後改裝opcv3.1……但仍然bug不斷，好在最好都解決了……

1.cmake報錯：（跟opencv2.4.13的一樣）

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_nppi_LIBRARY (ADVANCED)

但要注意的是，改完之後，camke輸入要加上 -D CUDA_GENERATION=Kepler ，

否則會報CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206 (message):

  Error generating 的錯誤

2.make報錯：

*** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o] Error 1 

make[1]: *** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/all] Error 2 

make: *** [all] Error 2
