我试图安装camlzip(一个安装在opam中的OCaml软件包),但是当我运行opam install camlzip时,我得到了这个:

=> This package relies on external (system) dependencies that may be missing. `opam depext camlzip.1.05' may help you find the correct installation for your system.

现在我认为很明显它并没有实际上缺少依赖关系,但我仍然可以提出建议的命令,它说我并没有错过任何依赖关系。

据推测问题出在zlibstubs.c文件中,但我并不完全确定发生了什么。

有人可以解雇我吗?

TL; DR

opam install depext
opam depext camlzip

说明

opam install depext命令将安装一个能够安装外部依赖项的opam插件。它会向depext工具添加opam命令。

opam depext camlzip将使用系统包管理器安装外部依赖项。如果不支持包管理器,则命令将失败。在这种情况下,您可以使用

opam list --external --required-by=camlzip

为包维护者已知的所有发行版和包管理系统获取camlzip的所有外部依赖项。根据此信息,您可以推断出您的分发包的名称。一旦成功,将这些信息反馈给维护者也是一个好主意。
