1.配置opencv

首先在vs中新建个项目，把下载到的tgz文件解压，然后把hpp的放到头文件，cpp文件放到原文件，然后调整项目的属性，引入opencv。
参考https://blog.csdn.net/gu1857035894/article/details/125473159，配置opencv
之后运行回报错，提示没有cv.h和highgui.h、IplImage未定义
就在头文件把引入cv的代码换成如下
#include<opencv/cv.h>
#include<opencv/highgui.h>
#include “opencv2/imgproc.hpp”

2.调整代码

首先注意调整地址和修改main中argc的默认值，使其为0：
在这里插入图片描述

使用了可能未初始化的本地指针变量“det”、‘l1’，新版cpp要初始化指针，给他们赋值NULL就行
目前我就遇到指针初始化和引入库的问题，如果小伙伴们遇到其他问题，根据错误提示修改就行
编译，执行会得到

3.perl、gnuplot

perl是生产gnuplot能够认识的代码，perl执行的是.pl文件，作者在eval__tool中写好了,注意也要修改一些地址：

#!/usr/bin/perl -w
use strict;
#### VARIABLES TO EDIT ####
# where gnuplot is gnuplot的exe文件绝对路径
my $GNUPLOT = "D:/gnuplot/gnuplot/bin/wgnuplot"; 
# where the binary is evaluate的exe文件绝对路径
my $evaluateBin = "F:/evaluation/evaluation/evaluate.cpp"; 
# where the images are fddb图片总路径
my $imDir = "F:/FDDB/originalPics/"; 
# where the folds are fddb路径信息、真值框信息文档路径
my $fddbDir = "F:/FDDB/FDDB-folds"; 
# where the detections are 最终生成的ROC图像存放位置
my $detDir = "F:/FDDB/";

sub makeGNUplotFile
{

my $pngFile = shift;
