Question

我已编写此代码以使用opencv库从网络摄像头捕获照片。

#include <opencv2/highgui/highgui.hpp>
#include<windows.h>
#include<iostream>

using namespace std;
using namespace cv;

void camcapture()
{
   VideoCapture cap(0);
    char name[100];
int i=0;
while(1){
    Sleep(1000);
    sprintf(name,"%s%d.jpg","test",i++);
Mat save_img;
cap >> save_img;

if(save_img.empty())
{
  std::cerr << "Something is wrong with the webcam, could not get frame." << std::endl;
}
// Save the frame into a file
imwrite(name, save_img); // A JPG FILE IS BEING SAVED
printf("image %s saved\n",name);
}

}
int main()
{
    camcapture();

}

然后我静态链接到一些必需的opencv库，使其可移植。当我编译代码时，可执行文件的大小是4.73，有没有办法减少可执行文件的大小而不影响可移植性？我不想动态链接库。这是编译日志。

这取决于您想要如何使用它。除了注释中的响应，您还可以使用可执行的打包程序，如UPX。

减少与opencv静态链接的可执行文件的大小
