Watch out for the libpng 1.4 update

[Gankfest]

Ok, so did what the first poster said. revdep-rebuild didn't fix any packages, when I go to emerge compiz-fusion I get this:

Code: Select all

-Wl,-soname -Wl,libnotification.so -o .libs/libnotification.so
/usr/lib/gcc/x86_64-pc-linux-gnu/4.4.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lpng12

So wtf, how do I fix it?

Read my first post in this thread and d2_racing post right below mine. They are a bit higher up on this page.

You're going to need to run 'lafilefixer --justfixit'. Follow directions and read. Your problem should be solved.

Ciao

Na did what both of you said and still have the same emerge fail and revdep-rebuild doesn't rebuild anything. Any other suggestions?

It's a hack but you can try to symlink libpng14 to libpng12 then try the above procedure. See if that helps.

Cross your fingers.

Good luck

It's kool that's what I did the first time, I'll just mask 1.4 and go back to 1.2. Why people release something that isn't needed by anything and will break your system is beyond me. I would of waited until it was needed and then released an ebuild that worked. Instead of releasing this crap and then having to hack libraries and then cross my fingers. Thanx for the help tho!

First of all you do understand / know that your running an unstable / testing arch , correct? If you want stable then change your arch in make.conf, but even then occasionally something new gets added that breaks your system when there is a significant change. For most of us we understand and accept that this is a drawback for running Gentoo. It's a source based, running Distro. since everything is directly compiled against whatever is on your particular system it sometimes requires a lot of recompiling. If you don't like it run Debian or Fedora.

It's just like when you have to upgrade GCC, and rebuild your system. Getting upset solves nothing!

The sticky warning of this major update to libpng and asking for volunteers to test it was posted at the top of this forum back in March. Instead of complaining about how screwed-up this update is, perhaps you can post a thorough bug report. Or help out next time.

Just to say I help out a lot more than you around here, but anyway I quit smoking today, I'm a bit testing my bad! ;P No one is perfect so lets just move on!

I can understand that. I've quit trying to smoke 3 times so far this year and still can't stop. I've lost count about how many other times I've tried to quit.

Getting back.... what exactly is failing to compile for you, besides compiz-fusion? Have you tried skipping it then trying to rebuild later?

Anyhow Good luck!

[FishB8]

app-office/gnumeric-1.10.3 fails to build. (after lafilefixer and revdep-rebuild)

[arnvidr]

@arnvidr:
You got nxclient to compile? HOW???

I didn't. Updating system installed 1.4, updating world downgraded it again. Anyway, the problem is gone now, the old version is now slotted automatically.

[gregool]

1. # emerge cairo pango gtk+ atk libglade qt-gui
1.b # Try revdep-rebuild again, with luck, you get a bit futher now

I owe you one ssuominen ! i couldn't figure out what would be the right order to emerge everything properly !

[SamuliSuominen]

media-libs/libpng-1.4.2 installs now brute force script to /usr/sbin:

Code: Select all

#!/bin/bash

echo "Run revdep-rebuild before this. This brute force script will rename"
echo "rest of -lpng12 and libpng12.la entries in your systems .la files."

[[ -d /usr/lib64 ]] && lib_suffix=64

libdir=/usr/lib${lib_suffix}

find ${libdir} -name '*.la' | xargs sed -i -e '/^dependency_libs/s:-lpng12:-lpng14:'
find ${libdir} -name '*.la' | xargs sed -i -e '/^dependency_libs/s:libpng12.la:libpng14.la:'

# WTFPL-2

That, with combination of revdep-rebuild, you should quite easily recover the system.

[gerard27]

Did an emerge --sync.
After that emerge -uDp world.
This is the result:

Code: Select all

These are the packages that would be merged, in order:

Calculating dependencies  .... done!
[ebuild     U ] sys-libs/timezone-data-2010i [2010b]
[ebuild  NS   ] media-libs/libpng-1.2.43-r2 [1.2.40]
[uninstall    ] media-libs/libpng-1.2.40 
[blocks b     ] <media-libs/libpng-1.2.43-r2 ("<media-libs/libpng-1.2.43-r2" is blocking media-libs/libpng-1.2.43-r2)
[ebuild     U ] sys-apps/man-pages-3.24 [3.23]

I am sorry to not grasp the meaning of a package blocking itself.
I am not going ahead with this.

Attention!

vmware-player needs libpng12.so.0 !

Solution

emerge libpng:1.2

ln -s /usr/lib64/libpng12.so.0.43.0 /usr/lib64/libpng12.so.0

[gemini91]

When this first showed up, the end of last week. I masked ligpng-1.4*. Then
found this report and followed it for a few days. I decided today to try the update
again. I followed this procedure from 'Odysseus"

Code: Select all

'emerge --oneshot libpng', 'lafilefixer --justfixit', 'emerge --oneshot cairo pango libglade GTK+' (omit emerging any which aren't installed) , 'lafilefixer --justfixit', 'revdep-rebuild' and for sanity's sake 'revdep-rebuild' again.

It worked with out any problems what-so-ever.

[gordonp]

I have read through the entire 3 pages of this thread (as the time of writing), so I was sort of prepared when my first stable amd64 system saw the libpng upgrade... lafilefixer and revdep-rebuild were completing without invoking any repair-work.

But still:

Code: Select all

dragon ~ # emerge -pDNuv world

These are the packages that would be merged, in order:

Calculating dependencies... done!

    (and 44 more)

I have no idea what (if anything) to do, at this point. I don't have the specified "media-libs/libpng:1.2" slotted package installed, yet I've had nxclient installed and working for a while, now (I am remote from this machine right now, and cannot check if nxclient is still working today)...?

...what to do?

[Martux]

I second gordonp's opinion. why has the slotting (which worked perfectly yesterday) been made undone?
Now the blocker is up again on two machines here.

[Anon-E-moose]

media-libs/libpng-1.2.40:1.2
media-libs/libpng-1.2.43-r1:1.2
media-libs/libpng-1.2.43-r2:0
media-libs/libpng-1.4.2:0


notice the slotting after each png release,

Yesterday or the day before libpng-1.2.40 was the only stable (amd64)
today it's all but libpng-1.4.2

[Martux]

Thanks Anon-E-moose. Does that mean that I would have to downgrade and rebuild all packages against libpng-1.2?
I don't want that, because my system works with both 12 and 1.4 installed. How do I tell portage that it should keep both versions installed for now?

[Anon-E-moose]

If you have both already installed then adding something like

Code: Select all

media-libs/libpng:1.2

to the /var/lib/portage/world file should keep the 1.2 version.

And I would add libpng-1.2.43-r2 to /etc/portage/package.mask as it is a "slot 0" like 1.4.2

[Martux]

And I would add libpng-1.2.43-r2 to /etc/portage/package.mask as it is a "slot 0" like 1.4.2

Great! That fixed it, thanks. Sometimes portage can be confusing, even after all those years

[albright]

And I would add libpng-1.2.43-r2 to /etc/portage/package.mask as it is a "slot 0" like 1.4.2

I'm confused about this - this morning I upgraded to libpng-1.2.43-r2.

It is now the *only* libpng I have installed. Everything works fine.

Of course, .43 puts in a libpng12.so.0 symlink.

I started trying to fix this issue before checking out this thread. First I had issues with the xf86-video-ati, so I reverted mesa and libdrm (to non-X11 overlay), and then ran revdep-rebuild. That showed me that libpng was also an issue, and I let it run until it was done. Didn't fix everything though, so I'm trying out lafilefixer now.

I just took out the big guns a couple of hours ago an ran

emerge -e gdm

which has been rebuilding 385 packages. Thank god for 8 cores and 4Gb of memory, right? There still seems to be some issues though, I'll need to check revdep-rebuild again afterwards. I'm just keeping my fingers crossed, hehe. I live in Sweden but I'm in Germany for 2 weeks, and my GF likes using the computer while I'm gone, hehe. And now there's no GUI =)
Thank Satan for SSH!

You shouldn't have a problem then
the quote above is if one is trying to keep 1.2.40 and the new 1.4.2 at the same time.

Gotta love these innocent looking portage updates. Usually pretty good at avoiding them, but not this time. So now, I stuck at building cairo:

Code: Select all

checking for cairo's PNG functions feature...
configure: WARNING: Could not find libpng in the pkg-config search path

Well, I have:

Code: Select all

[I--] [ ~] media-libs/libpng-1.2.43-r1 (1.2)
[I--] [ ~] media-libs/libpng-1.4.2 (0)

and ran

Code: Select all

lafilefixer --justfixit

Now trying to build cairo. Also: cat /usr/lib/pkgconfig/libpng.pc

Code: Select all

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/libpng14

Name: libpng
Description: Loads and saves PNG files
Version: 1.4.2
Libs: -L${libdir} -lpng14
Libs.private: -lz -lm
Cflags: -I${includedir}

So I don't understand why pkg-config can't find the new libpng.

SOLVED: I'm using a different cairo ebuild that was missing a patch for libpng14.

I pretty much did the same thing lol
