ubuntu22.04安装C++Opencv库

一、编译源码

cd opencv-XXX/

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
