dev-libs/icu-50_rc-r1:0/50

[andrewwalker27]

I'm having serious problems with upgrading dev-libs/icu-50_rc-r1:0/50 which makes my machine unusable until I downgrade to icu-49.1.2:0
I keep getting errors about missing libicuuc.so.49 but I'm not sure what package is dependant on the older version. I can't even start KDE until I downgrade, I tried revdep-rebuild but it didn't help.
Is anyone else experiencing this or have an idea how to fix it?

Guess I'm not the only one having troubles! It's been downgraded back to 49 now in unstable.

Yeh- I hit this mess on all my Gentoo ~Arch installs. I think this is only if you're running gcc-4.7.x, but not sure.

Boost, gptfdisk, and a few other packages seem involved too, and Chromium wouldn't update.

In my case, all terminals (Konsole, Terminator, xterm, whatever) opened, but had no prompts. Finally figured out you had to do a ctrl-alt-F1 to get a non-X functional terminal.

Then you can easily fix it up with:

I just made my toolchain upgrade using:

It is masked for a reason:
1. At a previous icu revision stage I could compile libreoffice but not chromium.
2. Today I can compile chromium but not libreoffice And the two days old libreoffice cannot start anymore.

With gcc-4.7.2 there is the implementation of new general c++ standard. Previous gcc versions had their own GNU-c++. To have ABI compatibility across our Gentoo distribution all is turned back to GNU-c++ for the time being.

Excuse my ignorance but what do I need to do to fix this?
After downgrading back to icu-49.1.2 I can't seem to either revdep-rebuild or update anything without problems.
Here's what versions I'm running, I'm using ~x86_64. I can't seem to upgrade KDE to 4.9.3 hence my other post

http://forums.gentoo.org/viewtopic-t-942062-highlight-.html

and I suspect this is due to the icu update/downgrade and I can't revdep-rebuild because most of the packages fail as well. I get openldap-4.9.3 failing to build along gnutls errors, samba fails because of openldap and so it goes on.

Here's a list of packages installed in case it helps

@andrewwalker27,
you normally get through by sticking to a single Gentoo release of the two (amd64 or ~amd64).
As you are at Gentoo~current there may be short times difficulties when transitions occur:
So I don't know what about boost-1.52 and boost-build-1.52 at this moment. (Because I am running all of these unreleased and masked packages at the moment.) You would surely get through by stibilizing to boost-1.49.0~r2 as long as you stick to gcc-4.6.3 and icu-49.1.2.

The steps I would do
- remove your specials in /etc/portage/package.unmask
- purge all of gcc but current~ gcc-4.6.3 _or_ try with fixlafiles tool and gcc-config.
- emerge -e @system
- emege $(qlist -IC kde) _or_ just normal emerge -uDN @world

Looks like downgrading boot isn't an option, it needs glibc downgrading as a dependancy.

000038 * Messages for package sys-libs/glibc-2.15-r3:
000040 * Sanity check to keep you from breaking your system:
000041 * Downgrading glibc is not supported and a sure way to destruction
000042 * ERROR: sys-libs/glibc-2.15-r3 failed (setup phase):
000043 * aborting to save your system

Tried lafilefixer --justfixit but everything said already clean, skipping update.

emerge -e @system seems a bit drastic but I'll give it a go tomorrow.
