以编程方式提取 .deb 包
我有 .deb 包，我需要以编程方式提取其内容。但是，我无法找到有关该主题的任何资源，例如 .deb 包格式规范，这将使我更多地了解如何在不对整个问题进行逆向工程的情况下解决问题。
有什么想法吗？
I have .deb package whose contents I need to extract in a programmatic way. However, I am not able to find any resources on the topic, such as .deb package format specification, which would give me some more idea how to approach the problem without going and reverse engineering the whole thing.
Any ideas?

实际上很简单。
要从 C 内部调用，您可以使用
system：Quite simple, actually.
To call from within C, you could use
system:如果您找不到这样的库（我也没有），并且无法诉诸运行系统命令，您始终可以实现自己的库来读取 ar 档案。 ar 文件格式并不是很复杂。
If you don't find a library for this (I didn't, either), and cannot resort to running system commands, you can always implement your own to read ar archives. The ar file format isn't terribly complicated.
.deb包格式的设计目标之一是使用现有工具和/或库轻松提取。顶层结构确实是一个 ar 文件，但在其中，您会发现另一层结构，传统上是一对 tar 文件。有关更多文档，请参阅 http://en.wikipedia.org/wiki/Deb_(file_format)如果您找不到现有的库，您可能可以使用 GNU ar 源代码来构建自己的库，我希望有 ar / tar / cpio / 的通用库。你。
One of the design goals for the
.debpackage format was to make it easy to extract using existing tools and/or libraries. The top-level structure is indeed anarfile, but inside that, you will find another level of structure, which is traditionally a pair oftarfiles. For more documentation, see e.g. http://en.wikipedia.org/wiki/Deb_(file_format)You can probably use the GNU
arsources to build a library of your own if you cannot find an existing library. I would expect there to be general libraries for ar / tar / cpio / what have you.我刚刚看到 libarchive 支持
ar格式，以及大量其他人的。I just saw libarchive supports the
arformat, along with a ton of others.
