ia32 apps look for libs on the wrong place

[Mahdi]

After upgrading from (up-to-date) gutsy -> hardy amd64 via update-manager -d, ia32 apps look for libs on /usr/lib instead of /usr/lib32 .
Particularly, 32bit apps that use icon themes and gtk engines complain about the ELF CLASS 64 of the engines (svg_loader.so) and show /usr/lib/(...)/svg_loader.so on the error message. Everything used to work fine on gutsy. As a result the icons are not shown, and a box with a red "X" is shown instead.
An example of such app is Swiftfox (from www.getswitffox.com, 3.0b3pre-6 - tested with prescott and pentium-m).
Firefox 3 from the repositories show the icons right.
The 32bit firefox from www.getfirefox.com have the same issue though.

32bit browsers are very important for us to have both flash and java plugins working properly (gnash and gcjwebplugin do not meet my needs).

[Matthias Klose (doko)]

then these libs have to be patch to get the correct libdir from the personalty at runtime

[Matthias Klose (doko)]

please recheck with http://people.ubuntu.com/~doko/tmp/ia32-libs_2.2ubuntu10_amd64.deb

[Sylvain Pasche (sylvain-pasche)]

I installed that package and tested again. The issue is still here (no stock icons).

 Error loading theme icon 'gtk-close' for stock: Unable to load image-loading module: /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so: /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so: wrong ELF class: ELFCLASS64

[Matthias Klose (doko)]

this contradicts your comment in https://bugs.edge.launchpad.net/ubuntu/+source/ia32-libs/+bug/177869/comments/11

which comment is the correct one?

[Xaweryz (xaweryz)]

To fix this I run commands :

sudo ln -s /usr/lib32 /usr/l32
sudo sed -i -e 's/usr\/lib/usr\/l32/g' /usr/lib32/gtk-2.0/2.10.0/loader-files.d/libgtk2.0-0.loaders
sudo sed -i -e 's/usr\/lib/usr\/l32/g' /usr/lib32/libgdk_pixbuf-2.0.so.0.1200.9
sudo sed -i -e 's/usr\/lib/usr\/l32/g' /usr/lib32/libgtk-x11-2.0.so.0.1200.9

This change string "usr/lib" to "usr/l32".

[Xaweryz (xaweryz)]

ia32-gtk-libs looks to /usr/lib !!!!!!!
Ia32-gtk-libs (libgdk_pixbuf-2.0.so.0.1200.9, libgtk-x11-2.0.so.0.1200.9) doesn't look to /usr/lib32 !!!!!!!

[Arthur (moz-liebesgedichte)]

I've just run into this after upgrading to hardy. First thought it's bug 162993, but at least svg_loader.so is present and the 32 bit Minefield binary is looking in /usr/lib/ instead of /usr/lib32.

Strange, my /usr/lib32/libgtk-x11-2.0.so.0.1200.9 doesn't have a reference to /usr/lib, neither when using ldd nor when grepping through it. Is it possible that the old file somehow survived the update?

Mesa in ia32-libs has the same problem.

~/bin32/gears is /usr/lib/xscreensaver/gears from xscreensaver on an ia32 Debian Etch system, IIRC. Any 32bit openGL program, even medibuntu's googleearth package, is affected.

So does libgphoto2 in ia32-libs. It looks for port plugins in /usr/lib, thus apps that depend on it cannot find any camera ports.

To reproduce:

1. verify 64-bit "gphoto2 --list-ports" outputs disk:/, usb:, etc
2. install lib32readline5
3. download 32-bit gphoto2 deb pkg
4. ar x gphoto2_2.4.0-1_i376.deb; tar zxf data.tar.gz
5. download 32-bit libcdk5
6. ar x libcdk5...i386.deb; ar zxf data.tar.gz
7. cd usr/bin
8. run LD_LIBRARY_PATH=../lib ./gphoto2 --list-ports

Expected result: same output as 64-bit gphoto2 --list-ports
Actual result: output is an empty list

[Saivann Carignan (oxmosys)]

Picasa 2.7 for AMD64 is not able to import photos with libgphoto because of this problem

[Jan Ploski (jpljpl)]

A possible workaround is to export GTK_PATH=/emul/ia32-linux/usr/lib/gtk-2.0 prior to starting a 32bit GTK application. This way I got rid of the "wrong ELF class: ELFCLASS64" warning concerning a GTK engine.

[Martin Karpinski (mkarpinski)]

Thanks Nico! Your workaround worked.

Never underestimate the power of getlibs ;)

Now, am I to undestand that, at least in my case, the error message

Gtk-Message: Failed to load module "gail": /usr/lib/gtk-2.0/modules/libgail.so: wrong ELF class: ELFCLASS64

was caused by libgail being a 32bit library and not compatible with amd64 architecture?

Yeap.
As far as I know, amd64 architecture switches on-the-fly to i386, but once
you are there all the execution should remain 32 bits.
That is why some 32 bit applications can run perfectly on amd64, just stuff
everything on the ELF executable, including all dynamic libraries and you
are done.
If you want to stay modular and use the dynamic linking process, you should
feed all the 32 bits libs the app will ever need.
It seems libgail.so is not part (yet?) of the ia32-libs, though.

Best, Nico

amd64 Linux kernels support ia32 processes running in 32bit compatibility mode. From the point-of-view of the 32bit process, it's pretty much the same as running under a 32bit (i386 architecture) kernel. (This is now called legacy mode on).

http://en.wikipedia.org/wiki/Long_mode
http://developer.amd.com/pages/123200367.aspx

 So yeah, when the dynamic linker in a 32bit process tries to load a shared library compiled for a different architecture, it returns an error, because it detected that the library is for a different architecture than the process. Just like if the file was a PowerPC or SPARC library.

 The kernel knows whether to run a process in 32 or 64 bit mode by looking at the same ELF headers that libraries have, and that file(1) will show you.

llama$ file /bin/ls
/bin/ls: ELF 32-bit LSB executable, Intel 80386, ...

tesla$ file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, ...

file works on share libs, too, of course.

[Michael Moss (mmoss)]

I think what the "libgail.so: wrong ELF class" error ultimately comes down to is that /usr/lib32/gtk-2.0/modules/libgail.so was removed from ia32-libs for some reason. Does anybody know why? GTK+ is clearly still looking for it, and it still exists in the 64-bit environment (hence the wrong architecture version that is being found), so why not in ia32-libs?

[The Fiddler (stapostol)]

"/usr/lib32/gtk-2.0/modules/libgail.so was removed from ia32-libs for some reason"

I can confirm this - anyone knows why?

[Scott Ritchie (scottritchie)]

The issue is that the libgail library was renamed from libgail18 to libgail-common.

[Scott Ritchie (scottritchie)]

I've got a local build of this working with libgail18 and libgail-common (and some other fixes), I'm going to try and upload it now. The source package is huge though and I'm having issues with dput. I may need to borrow a friend's non-comcast internet connection.

Scott Ritchie : Thanks for your work on this, however the libgphoto2 bug remains. Should I re-open this bug or report a new one? And do you have any clue on what is causing that issue with libgphoto? See https://bugs.edge.launchpad.net/ubuntu/+source/ia32-libs/+bug/190227/comments/23

[Scott Ritchie (scottritchie)]

i wonder if a simple rebuild of libgphoto2 and similar might fix it. Generally things go bad when the 32 bit libraries the program needs to link to aren't available at build time.

[Saivann Carignan (oxmosys)]

Scott Ritchie : Is that a valid theory considering that ia32-libs has been rebuilt recently by you last update, and considering the fact that the bug exist since intrepid? I don't know that much how ia32-libs work so I'm pretty confused about what can fix this issue.

This caused a number of problems with TB 3.1, creating multiple files & directories under ../Mail/ImapMail/mail.villanova.edu/* in the form of <foldername>-<index>.*, each with a different size. Also, TB 3.1 would constantly download messages. I then installed TB 3.2pre (64-bit), created a new profile & removed all of the extraneous files & directories. This seemed to resolve the immediate problem with TB, but not the actual problem with the libraries.

This is still an issue in Lucid Lynx (a regression?).
I have ia32-libs from lucid-proposed (2.7ubuntu26).

I have "official" 32 bit Firefox build fom Mozilla (for testing purposes). On start, I get this output:

/usr/share/themes/Ambiance/gtk-2.0/gtkrc:111: error: unexpected identifier `cellstyle', expected character `}'
/usr/lib/gio/modules/libgiogconf.so: wrong ELF class: ELFCLASS64

/usr/lib/gio/modules/libgioremote-volume-monitor.so: wrong ELF class: ELFCLASS64
Failed to load module: /usr/lib/gio/modules/libgioremote-volume-monitor.so

Also, notice the first line about Ambiance theme. It may be reated to the fall-back to default GTK theme (square, gray and blue-ish) for all 32 bit GTK appliactions (incl. Flash Player's context menu). This could be for separate bug report.

[Scott Ritchie (scottritchie)]

syntax, does that same thing happen if you don't use the -proposed ia32-libs?

To my knowledge the gio modules bits were never working properly, although some of the other libraries in this report were fixed

[Id2ndR (id2ndr)]

This is still an issue on Ubuntu 10.10 too.

[Robert Mens (robert-0xdeadbeef)]

This bug also affects me, no pixmaps in BOINC, missing images in the Firefox 4 beta.
Running on Ubuntu 10.10

[Robert Mens (robert-0xdeadbeef)]

After doing some more digging around I found a workaround for the gdk-pixbuf problem, described here: http://guide.ubuntuforums.org/showpost.php?p=683735&postcount=2

I've also noticed that /usr/lib32/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders tries to load all the x86-64 files from /usr/lib/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders so maybe it's a simple issue of a wrong path that's compiled in because of a 32bit chroot or something, as using strings on it results in a /usr/lib and not a /usr/lib32 string.

[Scott Ritchie (scottritchie)]

Per Robert's comment 55, there is still an open issue with gdk-pixbuf hard-coding /usr/lib that makes it stop working in the ia32-libs context. The same is true of the gio modules, which have been broken since at least Jaunty. I've opened tasks against each of them.

I will also note that libjasper1 is also not in ia32-libs, and gdk-pixbuf depends on it, so it should be added.

[Scott Ritchie (scottritchie)]

Actually see here for the gdk-pixbuf issue: https://bugs.launchpad.net/ubuntu/+source/gdk-pixbuf/+bug/641056

Reopening the ia32-libs task since it will need an update after there's a fix.

[Dean Diepeveen (dean-diepeveen)]

I've just upgraded to the latest ia32-libs for Maverick. I get this error.
"Setting up ia32-libs (20090808ubuntu7) ...
g_module_open() failed for /usr/lib32/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-jasper.so: libjasper.so.1: cannot open shared object file: No such file or directory"

It is likely that this error is from a previous upgrade error. Is there a simple way to check/fix the existence of these directories during the upgrade?

[Scott Ritchie (scottritchie)]

Dean, that's because libjasper1 isn't in ia32-libs. That should be a simple fix...

[Launchpad Janitor (janitor)]

This bug was fixed in the package ia32-libs - 20090808ubuntu8

---------------
ia32-libs (20090808ubuntu8) maverick; urgency=low

  * Add libjasper1 (LP: #190227)
  * Add libtalloc2 (LP: #653982)
  * fetch-and-build: use --only-source when getting source packages to avoid
    getting wrong source package for libjasper1

I also see similar problem on Ubuntu 10.04 64-bit.

I launch my gtk application from NFS mount point, then click the 'Browser' button of my application to open directory picker.

Then got below errors,

/usr/lib/gio/modules/libgioremote-volume-monitor.so: wrong ELF class: ELFCLASS64
Failed to load module: /usr/lib/gio/modules/libgioremote-volume-monitor.so
/usr/lib/gio/modules/libgvfsdbus.so: wrong ELF class: ELFCLASS64

/usr/lib/gio/modules/libgiogconf.so: wrong ELF class: ELFCLASS64
Failed to load module: /usr/lib/gio/modules/libgiogconf.so

I have installed ia32-libs, and update it to latest. And the same app works well on OpenSuse 11.2 64 bit.

Hope to reopen this one to get that fixing.

Status changed to 'Confirmed' because the bug affects multiple users.
