环境搭建
操作系统：windows10
mysys2：https://github.com/msys2/msys2-installer/releases/
popt1.16：http://ftp.rpm.org/popt/releases/historical/
mingw-64 32位：https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/
gnu make for windows：下载地址
将下载后的mysys2安装，根据提示来即可
到mysys2安装目录找到msys2_shell.cmd，右键编辑，将
rem set MSYS2_PATH_TYPE=inherit
改为
set MSYS2_PATH_TYPE=inherit
作用是取消注释，使得mysys2可以继承windows系统的环境变量，以使用之后的mingw进行编译
将popt-1.16.tar.gz解压到自定义目录，我解压到C:\Users\m\Downloads\popt-1.16.tar\
将下载的i686-5.2.0-release-win32-sjlj-rt_v4-rev1.7z解压到自定义目录，将其中的bin目录加入到windows系统环境变量path中
将下载的make.exe拷贝到mysys2安装目录的usr/bin目录下
到mysys目录打开msys2_shell.cmd，出现mysys窗口，输入gcc -v和make -v，弹出相应信息表示环境配置成功
对于代码的修改
程序是针对linux系统写的，对于windows系统，需要加以修改。这里参考：
https://github.com/mxe/mxe/blob/master/src/popt-1-win32.patch
列出的修改后的代码与原代码差异

编译
打开msys2_shell.cmd启动mysys2，切换到popt源码目录
cd /C/Users/m/Downloads/popt-1.16.tar/popt-1.16
输入以下命令编译
./configure --build=x86 --prefix=/C/Users/m/Downloads/popt-1.16.tar/popt-1.16/build
make
make install
编译后的文件存在于prefix参数指定的文件夹内，也就是C:\Users\m\Downloads\popt-1.16.tar\popt-1.16\build
include文件夹包含头文件，lib文件夹包含库文件，lib/pkgconfig文件夹包含popt.pc文件，可以被pkg-config工具识别并使用
