一、系統環境
Ubuntu：16.04
Linux kernel：4.4.0-130-generic
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.11)
二、OpenCV3.0.0安裝
解決環境依賴
根據官網安裝的教程 https://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html，選擇3.0.0版本的安裝教程，官網給出要求的依賴包爲
Required Packages
- GCC 4.4.x or later
- CMake 2.8.7 or higher
- Git
- GTK+2.x or higher, including headers (libgtk2.0-dev)
- pkg-config
- Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)
- ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev
- [optional] libtbb2 libtbb-dev
- [optional] libdc1394 2.x
- [optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev
依次系統的配置是否滿足要求(主要是GCC是否滿足)，其餘依賴包使用如下命令安裝：
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
獲取OpenCV源碼與編譯安裝
cd ~/
wget https://github.com/Itseez/opencv/archive/3.0.0-beta.zip
git clone https://github.com/Itseez/opencv_contrib.git
查看opencv和opencv_contrib兩個文件夾大小
vslyu@vslyu-Lenovo-G510:/media/vslyu$ du -sh opencv-3.0.0-beta/
185M opencv-3.0.0-beta/
vslyu@vslyu-Lenovo-G510:/media/vslyu$ du -sh opencv_contrib/
231M opencv_contrib/
保證 opencv 文件夾所掛載的磁盤剩餘空間大小在6GiB以上，進入opencv文件夾：
cd ~/opencv
mkdir build
cd build
在build文件下輸入如下指令配置CMakeLists.txt文件：
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
等待配置完成後，開始編譯：
