ubuntu16.04下CUDA9.1+OPENCV3.1安装记录

之前总是分开装CUDA和nvidia驱动，时常导致各种bug，于是这次一怒之下使用cuda官网的deb方式安装，同时装好cuda和nvidia驱动，但是cuda装的却是最新版本9.1,还没装opencv之前就想到一定会出现各种bug……

 一开始选择的是opencv2.4.13,结果cmake报错：

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)

按http://blog.csdn.net/u014613745/article/details/78310916  的解决方法确实可以解决这个cmake的问题。

然而！

make的时候却一直碰到no rule to target “……libnppist.so”的问题，尝试了一晚都解决不了。

于是最后改装opcv3.1……但仍然bug不断，好在最好都解决了……

1.cmake报错：（跟opencv2.4.13的一样）

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，改完之后，camke输入要加上 -D CUDA_GENERATION=Kepler ，

否则会报CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206 (message):

  Error generating 的错误

2.make报错：

*** [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
