Ubuntu14.04安装Opencv2.4.9

环境:win7+vmware12,64位
虚拟机:Ubuntu-14.04,32位.


1.获得源代码
源代码:opencv-2.4.9.zip
链接:https://pan.baidu.com/s/1bpbKc4R
密码:5oq7
mkdir ~/tmp
cd ~/tmp
将文件复制到~/tmp目录.
unzip opencv-2.4.9.zip
cd opencv-2.4.9


2.卸载ffmpeg和x264
sudo apt-get -qq remove ffmpeg x264 libx264-dev


3.安装依赖
sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm 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 
对于非英伟达显卡机器,使用ocl-icd-libopencl1替代libopencv-dev
笔者未实验,可以都试试.


4.安装ffmpeg
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg


5.编译安装
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
make -j2
sudo make install
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
—重启电脑


6.测试
cd /usr/local/share/OpenCV/samples/c 
sudo chmod +x build_all.sh 
sudo ./build_all.sh 
./facedetect "/usr/share/opencv/haarcascades/haarcascade_frontalface_alt.xml" lena.jpg 
或者 
./facedetect --cascade="/usr/share/opencv/haarcascades/haarcascade_frontalface_alt.xml" lena.jpg
笔者执行第二条指令成功了.
