Bugzilla Bug 70456

~x86 got upgraded to gcc-3.4.3 today. In course of a world update, portage
wanted to emerge kdenetwork-3.3.1-r1, which failed with following error
message:

This looks like libtool still wants to access the libstdc++ lib from gcc-3.4.2,
which does not reside on the system anymore as did upgrade to gcc-3.4.3 before
trying to emerge kdenetwork. However, all other kde ebuilds were built with
gcc-3.4.2 (and not upgraded) which might explain part of the error.

However, for minor gcc updates (e.g. 3.4.2->3.4.3) the c++ ABIs are binary
compatible and therefore should not be causing problems when upgrading.

Btw, the new gcc ebuild failed to automatically update the gcc-profile from
3.4.2 to 3.4.3, I had to do that myself with gcc-config.

I re-emerged libtool, did a ccache -C and cleaned out /var/tmp/portage, to no
avail.

Reproducible: Always
Steps to Reproduce:
1. emerge kde with gcc-3.4.2 (kdenetwork-3.3.1)
2. upgrade to gcc-3.4.3, re-emerge libtool, ccache -C
3. emerge kdenetwork-3.3.1-r1

Actual Results:  
emerge kdenetwork-3.3.1-r1 failed to emerge immediately after upgrading from
gcc-3.4.2-r3 to gcc-3.4.3.

Expected Results:  
kdenetwork-3.3.1-r1 should build and emerge successfully.

you can try runniong from root: 'fix_libtool_files.sh 3.4.2' 

on my system it was done automatically.. But I had to do the gcc-config by hand.

Thx for your hint Simone, my system is still builduing but it already passed
the obstacle mentioned in the bug report.
It seems to me the new gcc-3.4.3 ebuild is having some difficulties, as
emerging it did neither update my profile with gcc-config nor
fix_libtool_files.sh on my system. I had to manually do both before everything
went back to normal.
I'd suggest changing the bug reports component from KDE to Core Utils.

So it seems --> bug 70437.

Changes to paths (to point to 3.4.3 instead of some other version) in
/etc/env.d/05gcc needed and env-update re-run to regenerate  /etc/ld.so.cache
as far as I can tell.
