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 似乎没有什么要说的.我想做类似 Requires: vim or emacs 但是当我这样做时，我实际上依赖于 vim、or 和 emacs.依赖两个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

执行此操作的标准方法是通过虚拟提供:提供 RPM 的每个状态都表明它们提供了一个虚拟包，并且依赖的 RPM 需要该虚拟包.因此，在您的示例中，vim 和 emacs 都 Provides: text-editor，而您的包将 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，您可能会通过自己制作来解决这个问题.制作 Requires: vim 和 Requires: emacs 的虚拟 my-package-vim-mode 和 my-package-emacs-mode RPM，分别和Provides: my-package-text-editor，然后让你的包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.
