为Mac构建libunwind

Question

我试图在Mac上为iOS和Mac构建libunwind，我解决了很少的编译问题。

基于Mac的大楼

我使用以下方法配置了项目

./configure CC="cc -Ae -D_XOPEN_SOURCE=500"

并从谷歌的断续板项目中复制了elf.h。

https://google-breakpad.googlecode.com/svn-history/r1017/trunk/src/common/android/include/elf.h

我现在得到以下错误：

/usr/include/elf.h:58:15: fatal error: 'elf.h' file not found
#include_next <elf.h>

有人能帮我解决这个问题吗，或者还有其他一些程序来构建libunwind？

我还想知道是否还需要做些什么来为iOS构建libunwind。

Answer 1

我从libunwind开发者论坛上得到了一个答案。

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.

总之，Mac不支持。

Answer 2

libunwind包含在clang中，并由MacOS 10.6支持。
