ubuntu-16.04 - ubuntu 中的编译故障错误“SSL_CTX_ctrl”从指针目标类型中丢弃“const”限定符 [-Werror=discarded-qualifiers]

Question

我已经下载了hitch 1.4.8，我已经安装了以下软件包，libev-dev libssl-dev automake python-docutils flex bison pkg-config，./configure 输出没有错误，但是当我使用时继续下一步并执行“make”，它给出了这个错误：

make  all-recursive

make[2]: Entering directory '/root/hitch-1.4.8/src/util'

我以前在 ubuntu 16.04 上做过这个，但我不确定发生了什么。我在使用 aws 服务器的 linuxacademy 上执行此操作。有什么想法吗？
