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

. sudo apt-get update

. 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--dev libxine-dev libgstreamer0.-dev libgstreamer-plugins-base0.-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils

. sudo add-apt-repository ppa:jon-severinsson/ffmpeg

. sudo apt-get update

. sudo apt-get install ffmpeg

. 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

. cd opencv-3.1.

. mkdir build

. cd build

. 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./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".

解决方法：https://askubuntu.com/questions/691889/opencv-with-cuda-on-ubuntu-14-04-installation-error/691931#691931?newreg=470a4d740d374683be7b530f5df59393

The problem was the missing libnvcuvid library which could be solved with the two following commands:

. sudo ln -s /usr/lib/nvidia-/libnvcuvid.so /usr/lib/libnvcuvid.so

. sudo ln -s /usr/lib/nvidia-/libnvcuvid.so. /usr/lib/libnvcuvid.so.

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：

……

然后执行以下命令：

. make -j4

编译出现错误（2）如下：

解决方法：http://answers.opencv.org/question/41575/no-rule-to-make-target-usrliblibnvcuvidso-needed-by-liblibopencv_gpuso2/

Find out where libnvcuvid.so is located and create a softlink to it:

. locate libnvcuvid.so

. 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./build$ locate libnvcuvid.so

/usr/lib/nvidia-/libnvcuvid.so

/usr/lib/nvidia-/libnvcuvid.so.

/usr/lib/nvidia-/libnvcuvid.so.367.57

/usr/lib32/nvidia-/libnvcuvid.so

/usr/lib32/nvidia-/libnvcuvid.so.

/usr/lib32/nvidia-/libnvcuvid.so.367.57

yuanlibin@yuanlibin:~/opencv-3.1./build$

本文软链接命令如下：

. sudo ln -s /usr/lib/nvidia-/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：

解决方法：http://blog.csdn.net/xuzhongxiong/article/details/52717285

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

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

yuanlibin@yuanlibin:~/opencv-3.1./build$

最后执行安装命令：

. 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。
