visual studio code(vscode) c++ 编译opencv并运行调试

    vscode的优点我想用过都知道,这里只针对opencv编译贴上一些配置信息,对于用惯于IDE的我来说.配置这些还是要花一些时间去找资料的.

    准备工作: 1.opencv的安装已经完成(包插mingw-64,cmake)

                    2.vscode安装并安装cpptool支持插件

                    

vscode c++编译器中文输出乱码,如printf()或者cout,

        解决方法:将当前文件的编码格式改为gbk即可,  vscode窗口的右下角,点击显示的当前编码格式,输入gbk,保存,重新f5 进入debug中文打印就是正常了

配置vscode项目:

launch.json,task.json,c_cpp_properties.json

mian.cpp

#include <iostream>

#include <opencv2/opencv.hpp>
using namespace cv;
int main(int arg, char** args) {
	std::cout << "aa" << std::endl;

    std::string img = "D:\\timg.jpg";
    Mat srcImage = imread(img);
    if (!srcImage.data) {
        return 1;
    }
    imshow("srcImage", srcImage);
    cvWaitKey(0);
    return 0;
}

贴一个网上找的c++编译运行命令

linux->

g++ -o test test.cpp -I/usr/local/include -I/usr/local/include/opencv -I/usr/local/include/opencv2 -L /usr/local/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lpthread

参数解释:

    gcc -i 参数说明:包含头文件 -include和-I参数  

    gcc -l 参数说明: libopencv_core330  完整dll文件名,上面args载入的就是D:/opencv/build/x64/mingw/lib/libopencv_core330.dll.a
