Comment 2 Agostino Sarubbo gentoo-dev 2012-09-15 21:00:39 UTC
did you try emerge -1 sys-libs/libunwind ?
Comment 3 Jay Maynard 2012-09-15 21:05:15 UTC
When I started, I had libunwind-0.99 on the system. I manually emerged libunwind-1.0.1-r1 and tried again; the result is in the logs.

I just did the emerge -1 as you suggested, and got the same result.
Comment 4 Pacho Ramos gentoo-dev 2012-09-15 21:31:11 UTC
mono doesn't work on ia64 (it's not even keyworded)
Comment 5 Jay Maynard 2012-09-15 21:35:12 UTC
Mono's *supposed* to work on ia64, and it's supported there. That's what libunwind's all about. See .

Lots of things work that aren't keyworded. Once you get away from the all-the-world's-an-x86_64, you find that you have to tell portage to ignore the lack of a keyword to get lots of things done.
Comment 6 Pacho Ramos gentoo-dev 2012-09-15 21:48:11 UTC
It wasn't never keyworded and looks like it doesn't even compile, will CC libwind maintainers to figure out why it's not being detected, but you also need to attach config.log file. Also, not sure why do you expect we support mono on arches where it's not even keyworded, posting a link referring to a port in 2005 is not enough, you would be surprised how many obsolete webpages are still floating in, maybe it worked in the past but later broke again in more recent versions
Comment 7 Jay Maynard 2012-09-15 23:38:21 UTC
Seems I'm not the only one to trip over libunwind...see . I've been fiddling with various things in /lib and /usr/lib, but can't get it to be found no matter what I do.

I do note that that function only exists in libunwind-0.9.9, so that should be marked as a requirement.

And as for not being keyworded, I must repeat: keywording only gets done for i386 and x86_64; everything else is hit or miss. That something isn't keyworded for ia64 doesn't mean that it won't work, or that the keyword wouldn't be added.

config.log from install attempt

As requested. This shows the error generated from configure.
Comment 9 SpanKY gentoo-dev 2012-09-16 05:20:52 UTC
the error isn't that libunwind wasn't found (it was), it's that mono tried to use a symbol that isn't exported by it (the libunwind provided by gcc)

/var/tmp/portage/dev-lang/mono-2.10.9-r2/work/mono-2.10.9/conftest.c:213: undefined reference to `_U_dyn_register'
Comment 10 Pacho Ramos gentoo-dev 2012-09-16 07:49:02 UTC
Then, report this to upstream please:

Regarding this, I guess you have tried to send bugs asking to keyword things that already work ;)
Comment 12 Jay Maynard 2012-09-16 07:52:16 UTC
The symbol *is* exported by libunwind-0.9.9 as emerged in and found in /usr/lib/

And yes, I have submitted bugs asking for keywording, as it happens. Just not recently, and not under this email.
Comment 13 Jay Maynard 2012-09-16 08:01:17 UTC
Reported upstream:

I'm still not sure this isn't a Gentoo packaging error, however. Why doesn't emerging libunwind completely replace what's already there?
Comment 14 SpanKY gentoo-dev 2012-09-16 21:49:51 UTC
ia64's gcc has always built/installed libunwind itself because it relies on it for unwinding things at runtime.  that does not provide the symbol in question.
Comment 15 Jay Maynard 2012-09-16 21:55:58 UTC
Same question, though. Since gcc's libunwind doesn't work, how do we force it to use the one that does?
Comment 16 Jay Maynard 2012-09-16 22:54:45 UTC
Just answered my own question: mv the gcc-supplied one out of the way. Then it finds the emerged 0.9.9 library and configures and builds fine.

The problem is that it still looks to not work with sys-libs/libunwind-1.0.1-r1 and forcing a depend on older libunwind version would lead us to bug 414997 :(
Comment 18 Jay Maynard 2012-09-17 12:10:17 UTC
Hm. OTOH, 0.9.9 and 1.0.1 do use a different library level (0.9.9 is level 7, 1.x is level 8). Perhaps 1.x should be given a different name, since it uses a different interface?
Comment 19 SpanKY gentoo-dev 2012-09-17 17:12:36 UTC
(In reply to comment #18)

it already uses a different name -- .7 vs .8

we're not diverging from upstream libunwind which means renaming libs isn't going to happen
Comment 20 Pacho Ramos gentoo-dev 2012-09-17 19:17:33 UTC
Not sure if slotting libunwind would be possible :/
Comment 21 SpanKY gentoo-dev 2012-09-17 19:35:21 UTC
i don't think it would, and it'd make life hell for everyone else i think
Comment 22 Pacho Ramos gentoo-dev 2013-05-24 19:07:22 UTC
This will need to wait for upstream as no fix/workaround that we could apply looks to be available. 

As a side note, 3.0.7 was just bumped, maybe something changed in that new upstream version :|
