如何构建苹果的开源libc? [英] How to build apple's opensource libc?

问题描述

我正在尝试构建Apple的开源libc(来自 http://在我的OS X 10.6.8笔记本电脑上www.opensource.apple.com/source/Libc/Libc-763.11/).这实际上是为了获取/usr/lib/libSystem.B.dylib的本地生成的副本，我打算对此做进一步的实验.

I'm trying to build apple's opensource libc (from http://www.opensource.apple.com/source/Libc/Libc-763.11/) on my OS X 10.6.8 laptop. This is in an attempt to essentially get a locally generated replica of /usr/lib/libSystem.B.dylib, which I intend to experiment on further.

不过，我看到了几个基本的障碍(除非，很明显，我缺少一些基本的东西):

I see a couple basic roadblocks though (unless, obviously, I'm missing something basic):

• 没有有关如何进行构建的说明.我在上面引用的URL中有几个Makefile文件，但是当我尝试做简单的make时，它们却无法构建:

$ make -f Makefile

$make -f Makefile

Makefile:14:***缺少分隔符.停止.

Makefile:14: *** missing separator. Stop.

• 我怀疑可下载的源不完整.从Apple并未揭示所有更改的角度来看，这并不是不完整的，但是从(大概)没有被Apple修改的源文件的角度而言，这并不是完整的，因此不包含在集合中.例如，我看不到开放"窗口的实现.调用(在gnu libc层次结构中，可从io/open.c获得)

经过一番谷歌搜索后，我能找到的最接近的参考文献是:

The closest reference I could find after some googling was this: http://www.projectosx.com/forum/index.php?showtopic=1922&st=0&p=12457&#entry12457 but it still isn't close enough for my taste!

有指针吗?

谢谢！

推荐答案

仅一些通用指针(尽管某些链接正在讨论较旧的OSX版本):

Only some general pointers (although some links are discussing older OSX versions):
