ubuntu22.04 搭建 Opencv & C++ 环境

一、编译源码

安装依赖

sudo apt-get install libgtk2.0-dev pkg-config libcanberra-gtk-module libcanberra-gtk3-module

下载opencv源码

OpenCV官网

解压

unzip opencv-XXX.zip

进入

cd opencv-XXX/

创建cmake build

mkdir build && cd build

编译

cmake -D CMAKE_BUILD_TYPE=Release \-D CMAKE_INSTALL_PREFIX=/usr/local \-D WITH_GTK=ON ..

make -j$(nproc)

安装

sudo make install

这时候会安装到/usr/local/include目录中

用法：

#include  <opencv4/opencv2/opencv.hpp>

int main() {
    
    std::string image_path ="./test.jpg";
    auto image = cv::imread(image_path);

    cv::imshow("image", image);
    cv::waitKey(0);

    
    

    return 0;
}

成功
