我正在尝试在 Mac 上为 iOS 和 Mac 构建 libunwind，我能够解决一些编译问题。
在 Mac 上构建
我使用
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
并elf.h从 google 的 breakpad 项目中复制。
https://google-breakpad.googlecode.com/svn-history/r1017/trunk/src/common/android/include/elf.h
我现在收到以下错误：
/usr/include/elf.h:58:15: fatal error: 'elf.h' file not found
#include_next <elf.h>
任何人都可以帮我解决这个问题或者还有其他一些构建 libunwind 的程序吗？
我还想知道是否需要做其他事情来为 iOS 构建 libunwind。
libunwind 包含在 clang 中，并且从 MacOS 10.6 开始支持
我从 libunwind 开发者论坛得到了答案。
I don't think it will work. There's no OS X support in libunwind at the moment,
and the platform is quite different.
There is a sort of a libunwind (which has little or nothing to do with this one) in the
OS itself though. See http://opensource.apple.com/source/libunwind/
There's also some sort of symbolization library for post-processing. IIRC
you more or less want to use the tools that ship with base OS or at least Xcode,
otherwise you are up against writing quite a lot of tooling yourself.
简而言之，Mac OS X 不支持 libunwind。
