Resolved: | |
| Product: | Mac OS X |
Product Version: | 10.6.0/10A432 |
| Classification: | Other Bug |
Reproducible: | Not Applicable |
Summary:
The Mac OS X 10.6 source release at http://opensource.apple.com/release/mac-os-x-106/ includes the ld64 project at version 95.2.12, but it cannot be built due to a missing dependency on libunwind, the sources for which do not appear to be available.
Steps to Reproduce:
1. Fetch http://opensource.apple.com/tarballs/ld64/ld64-95.2.12.tar.gz.
2. Try to build it.
Expected Results:
It should be possible to build ld64 as distributed.
Actual Results:
Due to missing headers from libunwind, ld64 cannot be built as is.
Regression:
Haven't tried, but cf. Notes.
Notes:
Cf. e.g. http://www.opensource.apple.com/source/ld64/ld64-95.2.12/src/ld/MachOReaderRelocatable.hpp, with some of its includes:
#include <libunwind/DwarfInstructions.hpp>
#include <libunwind/AddressSpace.hpp>
#include <libunwind/Registers.hpp>
10.5.8's ld64 doesn't appear to require libunwind: http://opensource.apple.com/source/ld64/ld64-77.1/src/MachOReaderRelocatable.hpp

Please only post information for Radars that you have filed yourself, and please do

libunwind now available
here: http://www.opensource.apple.com/tarballs/libunwind/ and in older versions of lldb SVN tree.
Yep, I did see that — unfortunately, only after filing that radar. Mea culpa.
Not necessary to file (extra) radars on this
See http://lists.apple.com/archives/Darwin-dev/2009/Sep/msg00031.html and the follow-ups. The reason is that this is a legal rather than a technical issue, and somehow multiple radars are counterproductive in that case.
What is the legal issue here? I am no lawyer (far from it!), but it seems Apple has not had issues releasing their changes to other MIT-licensed projects.
