错误提示都不看的吗，

configure: error: Couldn't find libc-ares. Try installing libc-ares-dev or c-ares-devel.

提示你缺少c-ares库，自己先把缺少的库给编译了。 需要具体步骤看这里http://www.chengcan.me/windows/%E5%9C%A8Ubuntu%E4%B8%8A%E4%BA%A4%E5%8F%89%E7%BC%96%E8%AF%91Windows%E7%89%88%E6%9C%AC%E7%9A%84ss-local%E5%92%8Csimple-ofbs.html

打开cygwin setup > 搜索libcares-devel > 从Libs中找到libcares-devel安装

MinGW 下需要自己编译 c-ares https://github.com/c-ares/c-ares/blob/master/INSTALL.md
