- a full rebuild of quantal
right?
why? not every package like LibreOffice turns off verbose build logs so you can
see from the log how the package was built.
Im getting really cautious to jump to comclusions, but I kinda suspect there is
still dirty C++11 ABI in quantal somewhere:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1017125/comments/27
Im getting quite desparate here. I also looked at libreoffice with
LD_DEBUG=all, but didnt find an obvious clue.
So short of recompiling all of the build-deps of LlbreOffice (which are 417
plus those that are already on the buildd by default) and then toggling through
each package to see which one is 'guilty', Im out of ideas.
As for recompiling: Thats also not trivial: If I start from quantal I risk
keeping the dirty stuff in somewhere (e.g. via static linking). If I start from
precise, I would need to carefully figure out the incremental build order to
keep the deps happy, which might be nontrivial.
So, hints and ideas welcome (and desparately needed).
Best,
Bjoern
P.S.: BTW AFAIK both Fedora and SUSEs build services do a full rebuild of all
reverse dependencies on package update. That clearly would have prevented some
pain here.
I don't know where are the state of our C++ libs, but I got confirmation
that after they got the gcc 4.7 ABI fix for c++11, they indeed rebuild
the whole std stack, including libsigc++. Are we safe in that regard?
(can I try to switch unity back to 4.7?)
Thanks,
Didier
