[SOLVED]libpng12.so.0: cannot openshared object file

guisacouto · 2010-01-31 19:07:20

well I guess I updated my system too soon..

I updated my arch and the repos were probably out of sync or something and it messed up everything..
now every-time I try to open almost every app I get this error:

error while loading shared libraries: libpng12.so.0: cannot open shared file: No such file or directory.

I already tryed to pacman -S libpng to reinstall it put it didnt seem to work.. whats the trick?

best regards!

What is "almost every app"?

guisacouto · 2010-01-31 19:13:07

forget about it.. i thought that the problem was with libpng, but I didnt know that libpng12 was actually another lib.. and it wasnt installed as a dependency on the other updates (and it also wasnt in the official repos).

only noticed this when I searched in yaourt for libpng and found libpng12

i guess its solved! tks anyway!

Note that libpng12 is only a temporary workaround, the correct solution is rebuild and/or patch apps for the new libpng (as you *already* read on arch news about the rebuild)

I didnt know that and that was the problem.. the thing is.. libpng12 should come as a dependency or should be in the official repos in my opinion..

can you post a list with all new packages updated?

mechmg93 · 2010-01-31 20:52:47

i have excactly the same problem.

chromium, gparted, etc do not run because of the libpng12 issue . As a temporary solution i installed libpng12 from aur but i am waiting for an official fix.

edit:

i just opened a bug report :

http://bugs.archlinux.org/task/18095

really i don't understand why did you open a bug report. is even invalid. lets try to debug why is not working for you.
i'm asking again the list of packages you updated.

guisacouto · 2010-01-31 21:08:35

how can I post a list of the last updated packages? is there an easy way @wonder?

i, the person who opened the bug report, am not the person who you asked the list, and the reason i opened it , it's because it's a bug. so simple.

do a cat /var/log/pacman.log and chose the last updates and paste them to http://pastebin.ca

i know. but saying you have the same problem doesn't matter is a bug. maybe both of you having packages unsupported installed.

mechmg93 · 2010-01-31 21:24:22

Wonder, if a third and fourth person comes with the same problem, please remember that someone had tried to open a bug report

Your bug report dont have *any* information, so it dont help anyone. First, before posting a bug report, learn how to post bugs reports.

You dont post what exactly program give the error (version, release, repo), if the program is rebuild for libpng14 (something you need to search for), if some patch exists for it. This is all tasks of a bug reporter.

nope, wonder i will not post logs here and there is one reason :

when some months ago, we were discussing here in the forums the issues with kde and libjpeg7, when the developers moved the package to official repos and everything became a mess, the reply from developers was that there was not a bug report.

So you, the developers of archlinux, should discuss and and decide the method of solving archlinux problem. Until then, the only place i will post logs is the archlinux bug tracker.

so lets research a bit more base on you "bug report". what happen is libpng was update to 1.4.0 but chromium didn't. maybe you have chromium from aur(WE CAN'T DO ANYTHING ABOUT IT) or you don't have chromium 4.0.249.78-2 . Reading the latest news, you where advice do wait couples of days.

I also had the same problem and fixed it with the libpng12 from AUR

Here is a list of packages that were updated: http://pastebin.ca/1773567

same problem as mechmg93. you are using other cairo package. pacman -Qs cairo. remove libpng12, rebuild cairo-whatever (look on our PKGBUILD in svn and take the sed line), install it with pacman -U and reinstall gtk2

Varnsen · 2010-01-31 21:53:29

Yep, I understand. I was using cairo-lcd from AUR.

guisacouto · 2010-01-31 21:56:51

the intervals of time are big and the packages werent updated at same time because the mirrors were not fully updated yet so I deleted the lines with:
[2010-01-31 17:28] synchronizing package lists
[2010-01-31 17:28] starting full system upgrade

http://pastebin.ca/1773575

hope it helps
