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. 坑

   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
