[gentoo-dev] Gentoo 1.2 to 1.4 update, HowTo do it and not break everything

Wheehey.
 time for the preliminary upgrade instructions for all those adventurous
souls that dont want to break everything but only something :)


Overview: 
 how to update from gcc 2.95.3 to 3.2 without breaking too much

1) build gcc / glibc /binutils / gettext packages to backup with
  emerge --buildpkg gcc glibc gettext binutils   (all in gcc 2.95.3)

Move theese aside in a place tagged as gcc 2.95.3 .


2) build an replacement gcc systems
change the profile to default-x86-2.0

export USE="-* build"
emerge --buildpkg gcc 
emerge --buildpkg binutils gettext texinfo glibc
unset USE

This will now replace your gcc with one without c++ and other such
things.. "oops" gcc is now gcc 3.2.. thats good.

Now, We remove all traces of gcc, *shudder*  
emerge -C gcc
and install the binary again:
emerge --usepkg gcc

now, next step... we want a fully working and competent gcc, glibc and
other things:

emerge --buildpkg gcc
emerge --buildpkg binutils gettext texinfo glibc

Lovely, a complete gcc 3.2 system installed! and not a trace of gcc
2.95.3's libstdc++ ...  This is the time when you go "oops" and whine a
lot.

or.. is it?

move aside your gcc 3.2 complete binaries, copy in gcc 2.95.3 ones
emerge --usepkg =gcc-2.95.3-r7 (whatever version it was you had
installed)
emerge --usepkg gcc

Now, you've restored gcc 2.95.3's paths and data, and overwritten the
gcc, g++ and others with those of gcc 3.2

check with /usr/bin/gcc -v
it reports gcc 3.2 for me


Now, edit /etc/env.d/05gcc
add :
LDPATH=/usr/lib/gcc-lib/i686-pc-linux-gnu/2.95.3

then run "env-update"


now your old c++ code will work again... everything is normal, until ...
soon..


This is as far as I've come today, my system works, c++ code works,
galeon works, blackbox runs. 

Beware though... when you start to mix c++ codes it will probably break
in strange ways.  Solution: recompile :)

 I hope this helps.....

To make sure that we wipe all traces of the old gcc when we build the
new "clean" and fully functional version.

the "USE="build" stuff makes sure that /usr/bin/gcc is overwritten, but
doesnt create c++ things,  this will make sure that you have an
"uncontaminated" system which only runs gcc 3.2 when you build the final
gcc, glibc binutils and other things.

This is because the old gcc 2.95.3 package had its own /usr/bin/gcc
which you -dont- want right now, you want to simply overwrite the "gcc"
binary with the new one from gcc 3.2 (complete build)



I've ran this for a while, and all packages work neatly, including big
bloats like mozilla and galeon that depend on c++

When you rebuild one c++ thing though, you need to rebuild the things
that depend on it as well as to not get colliding libraries.


A tip: 

for i in /usr/lib/*.so; 
do ldd ${i}|grep "2.95.3" - >/dev/null && qpkg -fv ${i} ;
done

this will list all libraries that depend on c++ from 2.95.3

in my case it was imagemagick, and Mesa from xfree.

then you can scan the binaries, those are more common

Actually the user will want to know all versions, consider two different
SLOT.. then you get to know that the package foo++ has linked c++ code,
but not if its 1.0.55 or 2.1.91, that both nicely coexist and have
different library dependencies.. since I'm in that position myself with
some things (glade-- gnomemm gtkmm)  I prefer to know the exact
versions, and then I can take the time to clean out old stuff that are
caught with the SLOT updates while I'm still at it.  Makes my whole
system a bit cleaner.


here we count on our users to have SLOT unset in their early system
installs, and thus are likely to have multiple versions or the same -r
due to this.

I think we can / should be able to cut the procedure down :



original profile:

emerge --buildpkg gcc glibc binutils 
move aside

change profile
export USE="-* build"
emerge gcc texinfo binutils gettext 

unset USE
emerge --buildpkg glibc texinfo gettext binutils gcc


Now, the original USE="build" gcc replaced /usr/bin/gcc, and this second
"emerge gcc" then doesn't realize theres a different version of gcc
there, and overwrites gcc, c++ and all.. Neato. no more emerge -C gcc
anywhere.


After this, re-add the /etc/env.d/05gcc-old with the gcc 2.95.3 path,
run env-update and test by launching... mozilla?

OK. Then: s/-fv/-f -v/

It's just that Your above suggested switch won't work (over here, that 
is) ...

Tried just

$ emerge imagemagick

and got

$ "This compiler version is unable to build binaries ..." I must admit - 
that happened before too.

Ah, thats correct, it needs to be -f -v   (I'm too used to GNU syntax it

okay, debugging time! My favourite behind that glorious moment when all
things work ;)

run /usr/bin/gcc -v 
/usr/bin/c++ -v

check that both are gcc 3.2 _pre

make sure that /etc/ld.so.conf has both gcc paths in it 


look in //var/tmp/portage/imagemagick-*/work/imagemagick*/config.log and
check the exact compile message / errors.

to have mixed c++ and gcc versions will surely break things.  been
there, done that.

OK, I followed your excellent tutorial and now I have gcc-3.2.  I have 
to rebuild a bunch of stuff:
xfree, imagemagick, bcast, clanlib, fam-oss, gtkglext, gtkglarea, id3lib, 
postgresql, pspell, pspell-ispell, avifile and wxGTK.

I had to comment out the "no-mmx" stuff in xfree's ebuild because that 
option wasn't allowed.  xfree is building now.

But I still have c++ at 2.95 - how can I change that?

As expected... You installed the gcc 3.2 USE="build" binary on top of
gcc 2.95.3

emerge gcc ;
, will fix it, since gcc -v has the "right" version you dont
need to fool it for anything to get a correct c++ version.


After the emerge you'll have a c++ -v as "3.2" as well
