一、先安装的配置文件 sudo apt-get install build-essential sudo apt-get install cmake sudo apt-get install pkg-config sudo apt-get install libgtk2.0-dev sudo apt-get install libavcodec-dev sudo apt-get install libavformat-dev sudo apt-get install libswscale-dev sudo apt-get install libtiff-dev sudo apt-get install libjasper-dev sudo apt-get install libopencv-dev
二、编译OpenCV源码（先下载opencv2.4.9安装包） sudo unzip opencv-2.4.9.zip cd opencv-2.4.9 sudo mkdir release cd release sudo cmake -DCMAKE_BUILD_TYPE=RELEASE -DWITH_FFMPEG=OFF -DENABLE_PRECOMPILED_HEADERS=OFF -DCMAKE_INSTALL_PREFIX=/usr/local .. /**************************出现错误********************************/ 第一个错误与解决 linux/videodev.h not found sudo apt-get install libv4l-dev sudo ln -s /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h 第二个错误与解决 sys/videoio.h not found sudo cp /usr/include/opencv2/videoio/videoio_c.h /usr/include/arm-linux-gnueabihf/sys sudo ln -s /usr/include/arm-linux-gnueabihf/sys/videoio_c.h /usr/include/arm-linux-gnueabihf/sys/videoio.h 第三个错误与解决 Cmake error in cmakefile********SMP4300 sudo apt-get install gedit sudo gedit /home/pi/Downloads/opencv-2.4.9/cmake/OpenCVEetectCXXCompiler.cmake 将原文全部删除，改为如下内容，重新执行sudo cmake ****指令
