[gentoo-user] gcc 4.1 with gentoo 2006.1

[gentoo-user] gcc 4.1 with gentoo 2006.1

[Stefan G. Weichinger]

I just was doing heavy updates here to use up my monthly download-volume
 when I got in via eix-sync that there was a stable gcc-4.1.1.

Browsed the web a bit and saw that Gentoo 2006.1 was released.

Hooray ! ;-)

I just *ask* ....

Is it recommended/worth it/useful to recompile my stuff now?

Remembering recent threads I assume this leads to some "emerge -e
system; emerge -e world" to get the full BANG out of it.

Any pointers to some infos on the improvements with gcc-4.1.1 that are
also understandable for a non-programmer?

Greets to you, have a nice september,

Stefan.

Ok, ok, I am following the GCC Upgrade Guide now ...
Sorry for FAQing.

I updated to 4.1.1 some time ago & have been recompiling packages
only when there's a newer version; others remain compiled by 3.4.5 or 3.3.6 .
It doesn't seem to break anything.  I never do 'emerge world' anyway.

HTH FWIW ...

But according to the guide and to some threads here, it is highly
advised to do the emerge -e system and a emerge -e world as in the
guide.  It !currently! says this:

Since this is a major upgrade you may want to reconsider.  So I guess it
depends on how much risk you want to take with it.  If anything, at
least do a emerge -e system.  That should get you booted even if the GUI
fails for some reason.

As has always been the case, C++ applications are probably the most 
likely to be affected by ABI changes.  So, if you run KDE or Qt apps, 
then it is probably a very good idea to rebuild world.

what about glibc upgrade (was: Re: [gentoo-user] gcc 4.1 with gentoo 2006.1)

[tdrueke]

Sorry for capturing the thread. :)

What about the glibc upgrade from 2.3 to 2.4.
Does the same concerning "emerge -e world" apply here
(e.g. it is recommended to do it) ?

Or is it a more relaxed situation and simply emerging glibc 2.4 is
enough ?

When you emerge -e world for the gcc upgrade, you will get the new glibc.

[tdrueke]

Sorry, didn't make my point clear.

I already upgraded to gcc-4.1.1 with profile 2006.0
(by ~x86 keyword) with "emerge -e system && emerge -e world".
Switching to 2006.1 now leads to glibc upgrade.

Is it necessary to perform "emerge -e world" again ?

No.  Simply library updates never require rebuilding the packages that
use them, unless the major version number changes.  FEX if it
installed libc.so.7 instead of libc.so.6.

Thanks for the info. Saved two days of compiling... :)

simply emerging glibc 2.4 should be enough. I can't remember that I ever did 
an -e world after a glibc update.

Or just rebuild QT and KDE. That's all I did, along with glibc to be on
the safe side, with no apparent problems. Although I do run ~arch, so
most packages get rebuilt quite often in the normal course of events.

Exactly: Gentoo is all about managing your own system the way you like it,
so you remerge pkgs only when you want to or dependencies demand it.
