I am trying to build libunwind on Mac for both iOS and Mac, I was able to resolve few of the compilation problem.
Building on Mac
I configured the project using
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
And copied elf.h from google's breakpad project.
https://google-breakpad.googlecode.com/svn-history/r1017/trunk/src/common/android/include/elf.h
I get the following error now:
/usr/include/elf.h:58:15: fatal error: 'elf.h' file not found
#include_next <elf.h>
Can anybody help me in solving this problem Or there is some other procedure for build libunwind?
I would also like to know if something else has to be done to build libunwind for iOS.
I got an answer from libunwind developer forum.
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.
In short libunwind is not supported on Mac OS X.
