openCV2.4.13 安装

openCV2.4.13 安装

  1. 下载并解压

    
    unzip opencv-2.4.13.zip
    
  2. 进入openCV目录,建立release文件夹

    
    cd opencv-2.4.13
    mkdir release
    
  3. 安装依赖库

    
    sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev 
    
    sudo apt-get install -x264 v4l-utils ffmpeg 
    
  4. 进入release目录,cmake编译,把lib安装到 /usr/local/目录下

    
    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 ..
    
  5. 安装

    
    sudo make install
    

如果不想安装到/usr/local目录下的话,咋整?

  1. 
    CMake Error at CMakeLists.txt:14 (find_package):
      By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
      asked CMake to find a package configuration file provided by "Qt5Core", but
      CMake did not find one.
    
      Could not find a package configuration file provided by "Qt5Core"
      (requested version 5.0) with any of the following names:
    
        Qt5CoreConfig.cmake
        qt5core-config.cmake
    

    需要安装依赖 Qt5Core

    
    sudo apt install qtbase5-dev
