c++ - 如何在 Windows 10 上安装 jpeglib

Question

我有 64 位 Windows 10 操作系统。我已经从 JPEG 网站下载了 jpegsr9b 库，用于读取 JPEG 头文件。我用 C 编写了程序来读取 JPEG 文件，如下所示:

#include<stdio.h>
#include<jpeglib.h>
#include <stdlib.h>

int main()
{

struct jpeg_decompress_struct cinfo;

 struct jpeg_error_mgr jerr;

int height,width,pixel_size,colorspace,i,j,k,res;

FILE *infile = fopen("e:/Images/im.jpg", "rb");
cinfo.err = jpeg_std_error(&jerr);

jpeg_create_decompress(&cinfo);
jpeg_stdio_src(&cinfo, infile);
jpeg_read_header(&cinfo, TRUE);
jpeg_start_decompress(&cinfo);
width = cinfo.output_width;
height = cinfo.output_height;

printf("\nWidth = %d",width);
printf("\nHeight = %d",height);
}

然后编译为

gcc demo.c -ljpeg

但是报错

In file included from demo.c:2:0: jpeglib.h:25:62: fatal error: jconfig.h: No such file or directory compilation terminated.

如何解决问题？

从 here 安装二进制文件然后在 visual studio 中包含安装的 include 文件夹。
