Linux 我如何获得 Ubuntu 源代码？

How do I get the Ubuntu source code?

提问by Tom

Where can I find the source code for the latest Ubuntu release?

在哪里可以找到最新 Ubuntu 版本的源代码？

Also, how would I view the code? Would it just be lots of .cpp and .h files I could view in Visual Studio?

另外，我将如何查看代码？我可以在 Visual Studio 中查看很多 .cpp 和 .h 文件吗？

1. archive.ubuntu.com
2. Most of them are .c and .h files (not sure about C++), but certainly not all (some perl, some Python, etc). There will also be a lot of documentation files that aren't saved with .txt, just like READMEand LICENSE.

The source code for ubuntu is divided up by package - from a running ubuntu system you can easily retreive the source for any package by doing:

ubuntu 的源代码按包划分 - 从正在运行的 ubuntu 系统中，您可以通过执行以下操作轻松检索任何包的源代码：

apt-get source (package name)

Otherwise, go to launchpad, and search up the package in question. For example, here's the download page for the source code for a specific version of curl: https://launchpad.net/ubuntu/+source/curl/7.21.2-4ubuntu1

否则，请转到launchpad并搜索有问题的包。例如，这里是特定版本 curl 的源代码下载页面：https: //launchpad.net/ubuntu/+source/curl/7.21.2-4ubuntu1

That said, it's a lot easier if you're on a Linux system already - the package sources are divided into an original source tarball plus ubuntu patches, so if you don't use apt-get source, you'll need to manually apply the patch to the source code. And new-style packages are even divided into multiple packages.

也就是说，如果您已经在 Linux 系统上，这会容易得多 - 包源分为原始源 tarball 和 ubuntu 补丁，因此如果您不使用apt-get source，则需要手动将补丁应用到源代码。甚至新式包被分成多个包。

What's more, the packages are generally not designed to be cross-compiled from a non-Linux system. Even if you download them and open them in VS, you won't be able to build them from a Windows system.

更重要的是，这些包通常不是为了从非 Linux 系统交叉编译而设计的。即使您下载它们并在 VS 中打开它们，您也无法从 Windows 系统构建它们。

Finally, note that not everything is in C and C++ - there are packages in just about any language you can imagine. But I suppose most of them could be opened in VS as text files :)

最后，请注意，并非所有内容都使用 C 和 C++ - 您可以想象的几乎任何语言都有包。但我想它们中的大多数都可以在 VS 中作为文本文件打开:)

Note: If you really, reallywant all of it, and I can't stress enough how silly it would be to download everythingjust to start learning about the system, you can use the debmirrortool, available in ubuntu, to do this:

注意：如果你真的，真的想要所有的东西，而且我再怎么强调都不过分，为了开始学习系统而下载所有东西是多么愚蠢，你可以使用debmirrorubuntu 中提供的工具来做到这一点：

debmirror -a none \
          --source \
          -s main \
          -d lucid,lucid-security,lucid-updates \
          -r /ubuntu \ 
          --progress \
          -e http \
          -h archive.ubuntu.com \ ## or other ubuntu archive mirror
          destpath

This will be an absolutely huge download. Have several tens of GBs of space available. Note that this downloads only core packages - replace -s mainwith -s main,universe,multiverse,restrictedto get everything.

这将是一个绝对巨大的下载。有几十 GB 的可用空间。请注意，这仅下载核心包 - 替换-s main为-s main,universe,multiverse,restricted以获取所有内容。

Once you have the package files, you can extract the source by running dpkg-source -xon a .dsc file of interest.

获得包文件后，您可以通过运行dpkg-source -x感兴趣的 .dsc 文件来提取源代码。
