1、openGL安装
sudo apt-get install build-essential libgl1-mesa-dev sudo apt-get install freeglut3-dev sudo apt-get install libglew-dev libsdl2-dev libsdl2-image-dev libglm-dev libfreetype6-dev
2、cmake安装
sudo apt-get install cmake
3、git安装
sudo apt-get install git
4、opencv 安装
下载地址这里:https://opencv.org/opencv-3-4/
注:opencv4以上的是不默认生成.pc文件的,设置OPENCV_GENERATE_PKGCONFIG=ON后就会生成,其他版本设置了也没事.
依赖安装:
$ sudo apt-get install build-essential $ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev # 可选安装 $ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
opencv编译:
unzip opencv-3.4.0.zip cd opencv-3.4.0 mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DOPENCV_GENERATE_PKGCONFIG=ON -DCMAKE_INSTALL_PREFIX=/usr/local .. //$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON -D WITH_XINE=ON -D WITH_OPENGL=ON -D WITH_TBB=ON -D BUILD_EXAMPLES=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON .. make -j4 sudo make install
配置环境:
$ vim /etc/ld.so.conf.d/opencv.conf # 在文件中添加‘/usr/local/lib’ #先查看下opencv的共享库路径是在 /usr/local/lib 还是在 /usr/local/lib64 里面 $ sudo ldconfig
$ sudo cp -f /usr/local/lib/pkgconfig/opencv.pc /usr/lib/pkgconfig/
$ vim /etc/bash.bashrc # 在文件尾添加:‘PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH’
测试:
g++ `pkg-config --libs --cflags opencv` file.cc
