如何使RPM依赖于包A或包B? [英] How can I make an RPM depend on package a OR package b?

问题描述

这似乎是一个简单的问题，但是文档在这个问题上似乎没什么可说的.我想做类似Requires: vim or emacs的操作，但是当我这样做时，实际上我依赖于vim，or和emacs.依赖于两个软件包中的一个或另一个的语法是什么?

This seems like a simple question, but the docs don't seem to have anything to say on the subject. I would like to do something like Requires: vim or emacs but when I do that, I in fact depend on vim, or and emacs. What is the syntax for depending on one or another of two packages?

推荐答案

做到这一点的标准方法是通过虚拟提供:提供RPM的每个状态表明它们提供了虚拟包，而从属RPM则需要该虚拟包.因此，在您的示例中，vim和emacs都为Provides: text-editor，而您的软件包为Requires: text-editor.

The standard way to do this is via virtual provides: the providing RPMs each state that they provide a virtual package, and the dependent RPM requires that virtual package. So, in your example, vim and emacs both Provides: text-editor, and your package would Requires: text-editor.

如果您所依赖的软件包没有提供适当的虚拟软件包，那么您可以自己构建一个虚拟软件包.分别创建分别为Requires: vim和Requires: emacs以及Provides: my-package-text-editor的虚拟my-package-vim-mode和my-package-emacs-mode RPM，然后将其包装为Requires: my-package-text-editor.

If the packages that you're depending on don't provide an appropriate virtual package, you could probably hack around this by making up your own. Make dummy my-package-vim-mode and my-package-emacs-mode RPMs that Requires: vim and Requires: emacs, respectively, and Provides: my-package-text-editor, then have your package Requires: my-package-text-editor.
