Bugzilla Bug 80720

firefox refuses to start, effectivly:
** (firefox-bin:8134): WARNING **: /usr/lib32/pango/1.4.0/modules/pango-basic-fc.so: cannot open share
d object file: No such file or directory

Reproducible: Always
Steps to Reproduce:
1. emerge emul-linux-x86-gtklibs  #emerges 1.2
2. emerge firefox
3. firefox  #broken
4. emerge =emul-linux-x86-gtklibs-1.2
5. firefox  #works


Expected Results:  
Quickfix for firefox ebuild It should depend on 
                =app-emulation/emul-linux-x86-gtklibs-1.0
and not on 
                >=app-emulation/emul-linux-x86-gtklibs-1.0

Or fix emul-linux-x86-gtklibs-1.2 


With 1.1 firefox it works also, so only 1.2 is broken

Happy Workarounds using app-emulation/emul-linux-x86-gtklibs-1.2 :-)

# cd /usr/lib32
# ln -s /emul/linux/x86/usr/lib/pango pango

$ firefox

:-D

Thanks, this works.
Could someone fix that in the ebuild?

I dont think so, because this is only a workaround... not an elegant or correct
solution.

Also I found other workarounds.. 

inside /etc/env.d/50emul-linux-x86-gtklibs LDPATH is missing

LDPATH="/emul/linux/x86/lib:/emul/linux/x86/usr/lib"

and other workaround is to run this regex

:%s/\/usr\/lib32\/pango/\/emul\/linux\/x86\/usr\/lib32\/pango

to this file

/etc/pango/i686-pc-linux-gnu/pango.modules


I don't know what is the right solution, so it would be nice if some amd64 dev
take a look to this. :-)

I was having this bug, and I just made the symlink as suggested, and now
Firefox seems to work.  However, realplayer 10 (installed outside portage),
which was also broken before I made the symlink, has "broken image" icons in
place of where the images for Play, Stop, Pause, etc. are.  Just thought I'd
include that in case it's relevent to whoever tries to fix this correctly.

Please use media-video/realplayer-10.0.2 instead of manually install it. Just
unmask and keyword it. If you make this, that subject becomes relevant.. :-)

Problem's still here.  I had applied the dirty hack:
# cd /usr/lib32
# ln -s /emul/linux/x86/usr/lib/pango pango

but it came back to haunt me when I upgraded to 2005.0.  So we still need a real fix.

Also, from what I can gather it's a combination of xorg-6.8.2 and
emul-linux-x86-gtklibs-1.2 that's the problem.

This should be fixed now in CVS, app-emulation/emul-linux-x86-gtklibs-1.2-r1
creates the necessary symlinks. Please emerge it (~amd64) and let me know if it
solves your problems. If not please reopen this bug.

Works here.  Thanks =]

P.S. Might be a good idea to mark v1.2(-r0) as testing rather than stable.

Works here too. Thanks. Possibly it's a good idea to mark it amd64, since it
seems to work much better than the most recent stable one...

Output of emerge -vd emul-linux-x86-gtklibs 

Well, seams to work elsewhere, but 

roland@ferrari /usr $ file /usr/lib32
/usr/lib32: symbolic link to `../../emul/linux/x86/usr/X11R6/lib32'
roland@ferrari /usr $ file /usr/lib32/pango
/usr/lib32/pango: broken symbolic link to
`../../emul/linux/x86/usr/lib32/pango'
roland@ferrari /usr $ file /emul/linux/x86/usr/lib32/pango
/emul/linux/x86/usr/lib32/pango: directory
roland@ferrari /usr $

I'm still using 2004.3 profile, and somehow during resoluting of pango symlink
it first resolves /usr/lib32 and then the relativ symlink doesn't work any more

Would like to suggest to make an absolute path in symlink.

You have this line in your emerge output,

>>> /emul/linux/x86/usr/lib32 -> lib

Can you check that /emul/linux/x86/usr/lib32 is a symlink to /emul/linux/x86/usr/lib? If it is then the new ebuild detects that pango and gtk-2.0 are in fact directories and so does not create any symlinks. If it is not then there is a problem with your emul-* installation.

Yes, /emul/linux/x86/usr/lib32 -> lib, but no help ...

I then unmerged all emul-linux-x86-* packaged, did rm -fr /emul (Some lonesome files, mainly X11 related were still in), then emerge mozilla-firefox-bin 

=> Works (!)

Thanx

Sorry, after updating to 2005.0 profile (Makefile-profile_update-2005.0)
this problem has re-apppeared. See http://www.pinguin.tv/firefox-2.txt

I let this "as-is" now for further analyse requests...

Indeed, the problem re-appeared in 2005.0 for me too.
I solved it with the symlink to /emul/linux/x86/usr/lib/pango.

Try reemerging app-emulation/emul-linux-x86-gtklibs-1.2-r1 ?

I switched to 2005.0 a long time ago, so I had this problem with 2005.0.

Ok with emul-linux-x86-gtklibs-1.2-r1 firefox-bin works as that ebuild creates
the  pango symlink.
I'm wondering, wouldn't it be more appropriate if this is fixed in a way
similar to what Octavio Ruiz (Ta^3) suggested. The symlink seems a bit hacky
just for firefox to work. Of course, I don't know what other apps might or
might not depends on this symlink.

The fix supplied in app-emulation/emul-linux-x86-gtklibs-1.2-r1 works, and also
fixes issues with several other 32 bit apps (acroread 7 springs to mind), and
so represents the cleanest available solution. Not sure why the symlink is
nuked during upgrade, but it can be reestablished by reemerging the appropriate
emul lib.

I consider this issue fixed, if others have this issue I will ask for a note to
be added to the upgrade guide about emerging emul libs after the upgrade.

Ok, re-emerging emul-linux-x86-gtklibs-1.2-r1 only has solved this issue.
ACCEPT_KEYWORDS="~amd64" emerge emul-linux-x86-gtklibs
firefox, acroread work again. 

So the update to 2005.0 breaks this, we need to re-emerge above package.

This should be added to the upgrade guide.

Please refrain from using commands such as ACCEPT_KEYWORDS="~amd64" emerge
emul-linux-x86-gtklibs.  For more information see this post in the forums:
http://forums.gentoo.org/viewtopic-p-1060314.html#1060314

Even if you know what you're doing and know how to avoid the problems it can
cause, mentioning it can lead other users to try it and break their systems.

Sorry, as noted in comment 20 this issue is principially fixed in 1.2-r1,
but 1.2-r1 is still marked as "~amd64". So without (re)emerging that masked
version, this package renders useless, no firefox-bin, no acroread.

Can you give other advise, avoiding ~amd64 keyword, to get 1.2-r1 emerged 

If you sync you will find that I have in fact marked
emul-linux-x86-gtklibs-1.2-r1 stable (a few days ago now), as it fixes these
issues. So you will not have to use anything in ~amd64 now.

In the future, just use the package.keywords file to mix stable and testing
branches:

*** Bug 86828 has been marked as a duplicate of this bug. ***

Sorry, this "exactly" appears again with the 2.0 series of emul-linux-x86-*
ebuilds 

I just commited emul-linux-x86-gtklibs-2.1 to CVS which should solve this
problem (again). Please upgrade and be sure you run etc-update. Let me know if
this fixes it for you.

Ok, emul-linux-x86-gtklibs has fixed it again.

It appears that this is an issue again.  I am using
emil-linux-x86-gtklibs-2.10.6.3 and anything 32-bit is screaming about pango
and I can't read anything.  I noticed that the error is that it can't find the
pango/1.4.0 libs when in fact pango/1.5.0 is the one that exists.  Can anyone
help?
