在CUDA8.0下指定位置编译安装OpenCV3.1.0
一、本人电脑配置：ubuntu 14.04, NVIDIA GTX1060。
二、编译OpenCV3.1.0前，读者需要成功安装CUDA8.0(网上有相关教程)。
三、在CUDA8.0下编译安装OpenCV3.1.0。
1. 安装依赖库
1. sudo apt-get update 2. sudo apt-get install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils 3. sudo add-apt-repository ppa:jon-severinsson/ffmpeg 4. sudo apt-get update 5. sudo apt-get install ffmpeg 6. sudo apt-get install frei0r-plugins
2. 下载OpenCV资源
在OpenCV官网：https://opencv.org/releases.html，选择3.1.0，点击Source,下载opencv-3.1.0源码文件夹。
本人将opencv-3.1.0文件夹放置到 /home/yuanlibin目录下。
3. 编译安装
1. cd opencv-3.1.0 2. mkdir build 3. cd build 4. cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local/opencv_3.1.0 -D WITH_CUDA=ON -D WITH_CUBLAS=ON -D CUDA_FAST_MATH=ON -D WITH_CUFFT=ON -D WITH_NVCUVID=ON -D WITH_V4L=ON -D WITH_LIBV4L=ON -D WITH_OPENGL=ON -D WITH_FFMPEG=ON -D INSTALL_C_EXAMPLES=ON -D BUILD_EXAMPLES=ON ..
编译出现错误（1）如下：
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_nvcuvid_LIBRARY (ADVANCED) linked by target "opencv_cudacodec" in directory /home/yuanlibin/opencv-3.1.0/modules/cudacodec -- Configuring incomplete, errors occurred! See also "/home/yuanlibin/opencv-3.1.0/build/CMakeFiles/CMakeOutput.log". See also "/home/yuanlibin/opencv-3.1.0/build/CMakeFiles/CMakeError.log".
The problem was the missing libnvcuvid library which could be solved with the two following commands:
1. sudo ln -s /usr/lib/nvidia-346/libnvcuvid.so /usr/lib/libnvcuvid.so 2. sudo ln -s /usr/lib/nvidia-346/libnvcuvid.so.1 /usr/lib/libnvcuvid.so.1
This solves the cmake error and afterwards allows to use the cuda video codec with opencv.
（说明：ln是linux中一个非常重要命令。它的功能是为某一个文件在另外一个位置建立一个同步的软链接，这个命令最常用的参数是-s,具体用法是：ln -s 源文件路径 目标文件路径。）
再次编译之后，终端显示如下：
…… Parallel framework: pthreads -- -- Other third-party libraries: -- Use IPP: 9.0.1 [9.0.1] -- at: /home/yuanlibin/opencv-3.1.0/3rdparty/ippicv/unpack/ippicv_lnx -- Use IPP Async: NO -- Use VA: NO -- Use Intel VA-API/OpenCL: NO -- Use Eigen: YES (ver 3.2.0) -- Use Cuda: YES (ver 8.0) -- Use OpenCL: YES -- Use custom HAL: NO -- -- NVIDIA CUDA -- Use CUFFT: YES -- Use CUBLAS: YES -- USE NVCUVID: YES -- NVIDIA GPU arch: 20 21 30 35 -- NVIDIA PTX archs: 30 -- Use fast math: YES ……
然后执行以下命令：
1. make -j4
编译出现错误（2）如下：

Find out where libnvcuvid.so is located and create a softlink to it:
1. locate libnvcuvid.so 2. sudo ln -s /path/to/found/libnvcuvid.so /usr/lib/libnvcuvid.so
locate命令找到相应的路径。
yuanlibin@yuanlibin:~/opencv-3.1.0/build$ locate libnvcuvid.so /usr/lib/nvidia-367/libnvcuvid.so /usr/lib/nvidia-367/libnvcuvid.so.1 /usr/lib/nvidia-367/libnvcuvid.so.367.57 /usr/lib32/nvidia-367/libnvcuvid.so /usr/lib32/nvidia-367/libnvcuvid.so.1 /usr/lib32/nvidia-367/libnvcuvid.so.367.57 yuanlibin@yuanlibin:~/opencv-3.1.0/build$
本文软链接命令如下：
1. sudo ln -s /usr/lib/nvidia-367/libnvcuvid.so /usr/lib/libnvcuvid.so
如果显示已经存在，把相应的/usr/lib/libnvcuvid.so删除，重新编译。
编译出现错误（3）如下：

这是因为opecv3.0与cuda8.0不兼容导致的。修改 /home/yuanlibin/opencv-3.1.0/modules/cudalegacy/src/graphcuts.cpp文件内容，如下：
//#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)//ziji zhushi #if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION>=8000)//ziji tianjia
重新编译出现错误（4）如下：

解决方法：https://github.com/opencv/opencv/issues/5859
For fixing the problem, one more permanent solution is to add in /home/yuanlibin/opencv-3.1.0/samples/gpu/CMakeLists.txt the following lines:
find_package(OpenGL REQUIRED)#ziji tianjia
find_package(GLUT REQUIRED)#ziji tianjia
#ocv_target_link_libraries(${the_target} ${OPENCV_LINKER_LIBS} ${OPENCV_CUDA_SAMPLES_REQUIRED_DEPS})#yuanlaide
ocv_target_link_libraries(${the_target} ${OPENCV_LINKER_LIBS} ${OPENCV_CUDA_SAMPLES_REQUIRED_DEPS} ${OPENGL_LIBRARIES} ${GLUT_LIBRARY})#ziji tianjia

最后执行安装命令：
1. sudo make install
至此OpenCV3.1.0编译安装全部完成，指定安装到路径/usr/local/opencv_3.1.0。
这样GPU版本的opencv就编译安装完成了，可以调用opencv中GPU相关的函数。
