## 安装依赖 ##

for linaro 12.04

sudo apt-get install 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 libqt4-dev libgtk2.0-dev ffmpeg

for ubuntu 16.04

sudo apt-get install build-essential checkinstall cmake pkg-config yasm libtiff5-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev  python-dev python-numpy libqt4-dev libgtk2.0-dev ffmpeg

#### 卸载不必要的组件 ####

sudo apt-get remove libqt4-opengl-dev

## 安装OpenCV ##

下载，解压(省略)

wget opencv-xxx.zip
    
    unzip opencv-3.0.0-beta.zip
    
    cd opencv-3.0.0-beta

mkdir build
    
    cd build
    
    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local-D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D WITH_V4L=ON ..

cmake 编译选项

ccmake .

修改如下选项：

WITH_CUDA OFF
    
    WITH_CUFFT OFF
    
    WITH_OPENCLAMDBLAS OFF
    
    WITH_OPENCLAMDFFT OFF
    
    WITH_OPENGL OFF
    
    WITH_OPENCL OFF

按‘c’来configure，会提示错误，不用理会，按Esc返回。  
然后按’g’生成makefile

现在可以开始安装了

make
    
    sudo make install

大概两到三小时后安装完毕。

可能安装的目录为/usr/local-D/，如果是，则需要将该目录下的所有文件移动到/usr/local下

sudo mv /usr/local-D/* /usr/local/

然后运行以下命令使安装生效

sudo sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/opencv.conf'
    sudo ldconfig

## \[option\]配置pkconfig ##

vim /etc/bash.bashrc

添加

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig 
    export PKG_CONFIG_PATH

刷新使其生效

source /etc/bash.bashrc

测试是否成功

pkg-config --modversion opencv

## 测试OpenCV ##

新建一个Dis.cpp

#include <stdio.h>
    #include <opencv2/opencv.hpp>
    using namespace cv;
    int main( )
    {
        Mat image;
        image = imread("./lena.jpg", 1 );//目录按照自己的目录
        if ( !image.data )
        {
            printf("No image data \n");
            return -1;
        }
        namedWindow("Display Image", WINDOW_AUTOSIZE );
        imshow("Display Image", image);
        waitKey(0);
        return 0;
    }

编译

g++ Dis.cpp -o Dis.o `pkg-config --cflags --libs opencv`

可以看到输出一张美女图片
