cl创建opencv程序

环境

win8
VS2017或VS2013
opencv 3.2.0

配制环境变量

1. 解压opencv到某个目录,比如D:ProgramUninstall,把设置OPENCV_HOME为D:ProgramUninstallopencv320opencvuild
   2.添加 %OPENCV%in;%OPENCV%x64vc14in到path,这是为了程序在运行时能找到opencv要用的dll

测试程序

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace std;
using namespace cv;

int main(int argc, char **argv)
{
    Mat img = imread("2.png");
    if (img.empty())
    {
        cout << "adafd" << endl;
        return -1;
    }
    namedWindow("image", CV_WINDOW_AUTOSIZE);
    imshow("image", img);
    waitKey();
    return 0;
}

用以下命令编译链接,可以生成可执行文件.

cl /I D:ProgramUninstallopencv320opencvuildinclude  D:ProgramUninstallopencv320opencvuildx64vc14lib*.lib HelloOpencv.cpp /source-charset:utf-8

/I指定了头文件的位置.后面跟的是lib文件的位置./source-charset:utf-8指定utf8编码.
