[gentoo-user] *** WARNING *** - upgrade to libxcb-1.4 (-r1) breaks your system

[gentoo-user] *** WARNING *** - upgrade to libxcb-1.4 (-r1) breaks your system

[Helmut Jarausch]

Hi,

as I have just bitten by it, have a look at
http://bugs.gentoo.org/show_bug.cgi?id=285004

before upgrading to x11-libs/libxcb-1.4 (1.4.-r1)

since this breaks any X11-application (including your
browser to look at the URL above)

Such an update should be DOUBLY MASKED !!!

And the messages coming with libxcb just don't help.
revdep-rebuild doesn't help either.

And one cannot remerge the broken packages either,
since there configure bails out.

Oh dear, Gentoo !

Helmut.

The above URL doesn't help either,
so any help to 'survive' is appreciated.

Did  you read the elog message when you emerged the new version?

libxcb-xlib.so is no longer shipped by ${PN} but was kept on your system

While your system will still work, emerging new packages or updates
will likely fail. You can fix broken libtool .la files by running :

  ${FILESDIR}/xcb-rebuilder.sh

To completely get rid of libxcb-xlib.so references, please read :

Install links|links2|elinks|lynx and view the web page from the console

These text browsers are insanely useful things ;-)

Since my browser got broken, too, this took some time.
And following that advice takes even much more time, since
I have to rebuild half of my system.

Luckily it has 4 cores,

The gods must be favouring me for a change. I'm completely unaffected by this 
upgrade :-)

I had some breakage, but nothing significant. I only realised anything
was wrong because emerge @preserved-rebuild failed on most packages, so I
then RTFMed, ran the commands from that web page and all was fine.
Konqueror kept working fine, so I didn't need to remember how to work any
of the lynx variants.

You must be very lucky to have such a fast machine.

I'm following the recipe on
http://www.gentoo.org/proj/en/desktop/x/x11/libxcb-1.4-upgrade-guide.xml

which results in

emerge -v1 -j4 x11-proto/xcb-proto x11-libs/libxcb
emerge -v1 -j4 x11-proto/xproto x11-proto/xextproto x11-libs/libX11 x11-libs/libXext

/usr/portage/x11-libs/libxcb/files/xcb-rebuilder.sh

emerge -1 -j4 \
$(for i in x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
           x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
           x11-libs/pango x11-libs/gtk+ gnome-base/libgnomeui \
           x11-libs/qt-gui; do \
    qlist -IC $i; \
done) -v

revdep-rebuild -L libxcb-xlib.so.0 -- -j4 --ask --keep-going


This requires to rebuild 182 packages and proably several
hours on a modern PC (Phenom II 4 cores)

(this includes some not so tiny packages like gcc (2 slots)
several gnome and kde libraries)

(Sometimes, Gentoo is an expensive hobby)

Same here, no breakage on my laptop or desktop.

 I have used  dev-util/lafilefixer few time with "--justfixit" option
few times,could that be the reason for smooth upgrade?

Did you remove the lib "libxcb-xlib.so" or is it still there?

It temporarily broke my system too, but nothing dramatic:

emerge -1 -j4 \
$(for i in x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
            x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
            x11-libs/pango x11-libs/gtk+ gnome-base/libgnomeui \
            x11-libs/qt-gui; do \
     qlist -IC $i; \
done) -v

resulted in a build failure (a package complained about missing symbols 
in libxcb-xlib.so during the link step).  According to the upgrade 
guide, that was not supposed to happen.  The fix was easy though; I just 
ran revdep-rebuild at this point (not many packages needed a rebuild, I 
guess having "--as-needed" in my LDFLAGS saved the day) and then I 
repeated the command, finally deleted /usr/lib/libxcb-xlib.so* and 
everything was fine.

One other slight breakage was revdep-rebuild wanting to rebuilt the same 
package over and over again.  If revdep-rebuild wants to repeatedly 
rebuild a package, you have to unmerge that package first and then 
re-run revdep-rebuild; only then will you see the final packages that 
need to be rebuild (in my case, kde-base/systemsettings).

Of course, rebooting the machine before finishing all of this is not a 
good idea.

-j4?

if you want to give makeopts - that belongs into /etc/make.conf. I didn't even 
know that portage forwards those options

Re: [gentoo-user] Re: *** WARNING *** - upgrade to libxcb-1.4 (-r1) breaks your system

[Boris Fersing]

I didn't have any big problem neither. After uprading to libxcb-1.4 a
lot of packages failed to compile. I searched for warning messages
with elogv, followed the upgrade guide and now all is fine.

regards,

Boris

I don't have any file named libxcb-xlib* anywhere

And I don't remember removing such a file or ever reading an elog related to 
xcb.

yeah, almost the same here. Removed the file first, run the la fixer then revdep-
rebuilt and everything was fine.

No i did not remove it nor is it there , "slocate libxcb-xlib.so.0" returns nothing. Elogv for  x11-libs/libxcb-1.4-r shows only "INFO: prepare                                                                      x

emerge (at least 2.2) has it's own --jobs option to build several
packages in parallel, if possible.

Prehaps nothing.
Rebuild warning is triggered by a check for libxcb-xlib.so.0.0.0, which
didn't seem to exist on my system either.
Guess "xcb" use-flag for libX11 is to blame: if it's not set, then
older libX11 brought along it's own libxcb.

Are you saying this only breaks on slow machines? Machine performance is
hardly relevant when nothing broke that wasn't fixable by a background
revdep-rebuild while still using the computer.

Never argue with an idiot. First, they bring you down to their level.
Then they beat you with experience.

Yes, that's what it is. I too have USE="-xcb" for libX11

I have xcb use flag enabled and haven't encountered any problems (and
nothing had to be rebuilt). libX11-1.2.2

Maybe I missed it earlier in the thread but is this somehow a
byproduct of running ~arch vs stable? I do not have -xcb on any of my
machines and haven't seen any problems. (Yet...) I know a lot of folks
here do run ~arch but I don't.

Thanks,
