Chromium cries for 32-bit libraries

Hi. I use Arch 64-bit and built chromium from AUR today. At first, launching "chrome" command told me there's no libjpeg.so.62, so I symlinked the 7th version of libjpeg as 62. Then it said it's 64-bit, and it needs 32:

[warnec@chakra ~]$ chrome
/usr/lib/chromium-browser/chromium-browser: error while loading shared libraries: libjpeg.so.62: wrong ELF class: ELFCLASS64
[warnec@chakra ~]$

I had a similar issue with my printer driver (where program looked for 32-bit libraries not in /opt/lib32/usr/lib, but in /usr/lib) and rebooting helped. So I symlinked 7th libjpeg to 6.2 libjpeg in /opt/lib32/usr/lib and rebooted. Still the same error.

Re: Chromium cries for 32-bit libraries

hmm symlinking isnt a nice solution for your problem after updates it get's messy. Maybe try a chroot

Re: Chromium cries for 32-bit libraries

How do I use it?  You mean:

[warnec@chakra ~]$ sudo chroot /opt/lib32 chrome

?
In that case, it gives:

chroot: cannot run command `chrome': No such file or directory

Re: Chromium cries for 32-bit libraries

Maybe I found something. In /usr/bin/chromium-browser it says:

# On x64, 32bit gtk2 is not looking for modules in the right place.
# Workaround it by setting GTK_PATH. We also backup the previous
# value of GTK_PATH into CHROMIUM_SAVED_GTK_PATH so that chromium
# can restore it before calling native x64 apps using xdg-open
# also at-spi bridge does not work and causes crashes; we disable
# this explicitly by setting NO_AT_BRIDGE
if [ -d /usr/lib32/gtk-2.0 ] ; then
  export CHROMIUM_SAVED_GTK_PATH=$GTK_PATH
  export GTK_PATH=/usr/lib32/gtk-2.0
  export NO_AT_BRIDGE=1
fi

But:

[warnec@chakra ~]$ /usr/bin/chromium-browser
/usr/lib/chromium-browser/chromium-browser: error while loading shared libraries: libjpeg.so.62: wrong ELF class: ELFCLASS64
[warnec@chakra ~]$

Re: Chromium cries for 32-bit libraries

don't you need the corresponding 32bit libraries installed?
probably lib32-libjpeg?

I agree that symlinking is a bad idea.

Re: Chromium cries for 32-bit libraries

I have lib32-libjpeg installed. In other case, there won't be any lib files in /opt/lib32/usr/lib/. That's the problem - Chromium looks for libraries in the wrong directory.

Re: Chromium cries for 32-bit libraries

how does /usr/bin/chromium-browser looks up?
i see from aur build that is installing a custom wrapper. should be like this: http://aur.archlinux.org/packages/chrom … browser-64

Give what you have. To someone, it may be better than you dare to think.

Exporting the variables from here:
http://aur.archlinux.org/packages/chrom … browser-64

Didn't help. Same error message. I  built from here:

http://aur.archlinux.org/packages.php?ID=24266

not here:

http://aur.archlinux.org/packages.php?ID=26425

Don't know if it matters.

PS.: I don't have /opt/chromium-browser.

Re: Chromium cries for 32-bit libraries

what did you installed? use aur build http://aur.archlinux.org/packages.php?ID=26425 or if you prefer with google logo http://aur.archlinux.org/packages.php?ID=27031

Re: Chromium cries for 32-bit libraries

Ok, maybe I installed from wrong AUR site. I will use chromium-snapshot. But before that, tell me how to get rid of current chromium.

PS.:

 yaourt -R chromium-browser

Did the trick. Trying chromium-snapshot now.

Re: Chromium cries for 32-bit libraries

chromium-snapshot works. Everything starts like a charm.
