未找到 libprotobuf-c 和 libev4

我正在尝试在我的 Ubuntu VPS 上设置 Openconnect 服务器，首先我必须编译它，但每次运行时./configure都会出现 2 个错误：

configure: WARNING: ***
*** libprotobuf-c was not found.
***
checking for libev... no
configure: error: ***
*** libev4 was not found.
***

当我尝试安装时，libprotobuf-c我得到以下输出

root@MY_VPS_NAME:~# apt install libprotobuf-c
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libprotobuf-c

当我尝试安装时，libev4我得到以下输出：

root@MY_VPS_NAME:~# apt install libev4
Reading package lists... Done

答案1

protobuf 包现在称为libprotobuf-c1。 在libev4那里，如果您无法安装它，则您有通用存储库问题。
您的 Ubuntu 15.04 已过时，请升级到 15.10。 这可能是缺少软件包的原因。

答案2

我在 Ubuntu 18.04 中遇到了同样的问题，并且我安装了它libev-dev来修复它。
