我正在尝试安装camlzip(位于opam中的OCaml软件包),但是当我运行opam install camlzip时,我得到了:

=> 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,我认为很明显并没有丢失依赖项,但是我仍然可以建议使用该命令,并且它说我没有丢失任何依赖项。

大概问题出在zlibstubs.c文件,但是我不确定是怎么回事。

有人可以帮我吗?

最佳答案

TL; DR

opam install depext
opam depext camlzip

说明
opam install depext命令将安装一个opam插件,该插件能够安装外部依赖项。它将向depext工具添加一个opam命令。
opam depext camlzip将使用系统软件包管理器安装外部依赖项。如果不支持您的软件包管理器,则该命令将失败。在这种情况下,您可以使用
opam list --external --required-by=camlzip

获取软件包维护者已知的所有发行版和软件包管理系统的camlzip的所有外部依赖关系。根据此信息,您可以推断出要分发的软件包的名称。一旦成功,将这些信息回馈给维护者也是一个好主意。
