Watch out for the libpng 1.4 update

[Etal]

Just wanted to let everyone know that a new major version of libpng appeared in portage today, and if you update mindlessly, you will have massive breakage since libpng is used by practically all graphical packages.

So, if you choose to update to it, you will need to either:

- Rebuild a whole lot of major packages (51 in my case) with revdep-rebuild. (Portage 2.2 won't save you due to the block)

- Or, you would need to have both versions installed. Here's what I did:

[Jorgo]

Most of the necessary packages can't be rebuild. Some packages like wxGTK etc. don't find necessary packages. pkgconfig gives a lot of errors that it can not find some libs.

Big warning! You can not even start most of the gnome programs like gnome-terminal etc. All files claim libpng12.so.0
Using AMD64 unstable revdep-rebuilt wants to rebuild 177 files but fails instantly.
I masked libpng-1.4.2 locally and downgrade to libpng12 ...

My list (revdep-bebuild) is 56 packages, and it's going fine (on 25 of 56 now).

~amd64, portage <2.2. Only wm installed is e17 but I do use many gtk apps. ATM, terminal is refusing to launch a new instance, so I'll need to wait a bit before I know if anything is actually broken or just needed to be built against the new pnglib.

For now you can just put

yup big b0rkage

revdep-rebuild would list a load of applications needing a rebuild BUT the rebuild would fail early on (pygtk in this instance, it kept trying to -lpng12 EVEN tho 14 was installed
lafilefixer didn't fix it

I had to manually emerge libglade to get alot of things to rebuild (against libpng14)

Next set of blockages associated with imagemagick (need to find out which one of its deps is being a PAIN!).
Mangler doesn't work either due to it still gets linked against libpng12 during emerge oO which makes no sense

Key package deps and their *.la files have libpng12 coded in them and its a job to find out which ones are causing hte problem...


this is a nasty lib bump

All sorted here. revdep-rebuild finished and a running it again showed consistency.

I for one have only one problem left with net-misc/nxclient-3.4.0.7 which absolutely insists on libpng-1.2.
The other blockers, x11-misc/notification-daemon-0.4.0-r1 and dev-python/pygtk-2.16.0-r1 just played nicely after I did a lafilefixer --justfixit.
Any ideas on nxclient?

Whether it was me or portage that was mindless is kind of irrelevant - things are kind of fucked.

I had ~50 packages that needed rebuilding after revdep-rebuild and 25 of those still won't. These are;

pygtk, libgnomeprintui, gnome-media, libgnomecanvas-python, libgnomeui, libbonobo-python,
glade, dia, libgnome-python, teg, eel, celestia, anjuta, goffice-0.4.3, goffice-0.6.6, notification-daemon,
grip, evolution-data-server, evolution, gnome-mount, nautilus-actions, abiword, gnome-panel, gdm and
gnome-applets-python.

This is gentoo and I'm running unstable but this is the biggest breakage I've had in ages, something in eselect news
might have been nice... but it's a Sunday so what else should I do but worship at the altar portage, 25 "hail portages"
seems a bit of steep price for absolution though.

Thanks for the advice Naib, I did what you suggested, ran

[gregool]

it didn't go as i expected

i ran emerge libpng:1.2 as suggested, the symlinks are ok but revdep-rebuild never returned any broken package.

so my problem is that a bunch of packages are still asking for libpng12 ! i tried to emerge libglade as Naib suggested but it quiclky failed asking for libpng12 as well.

lafilefixer didn't do the trick

any ideas?

[Naib]

[gregool]

thx naib

well let's try to rebuild

[gregool]

didn't work

after i removed libpng12 revdep-rebuild found 99 broken packages, and the rebuild crashed on the very 1st package which was cairo so i tried so to rebuild libglade with no luck

[Naib]

iirc I had to emerge cairo by itself.

what is the error when you try to emerge cairo by itself?

I just wanted to make a similar post. 71 packages had to be rebuilt on my system, which made my PC basically unusable for 5 hours. revdep-rebuild fixed everything without problems, though.

[d2_racing]

Thanks for this thread, I'm gonna try tomorrow morning

[sumerman]

[davidm]

Thanks for the heads up. I think I'll wait a week or two before upgrading. I remember all the problems this caused in the past on Arch. Particularly Cairo but also for a lot of custom built apps.

[sumerman]

[gregool]

ok i emerged cairo by it self and it worked, but it seems every package has a different work around.

the 2nd on the list is libgnomecanvas-python-2.28.0, and it fails due to gtk+
