Bug 485742 – app-text/acroread-9.5.5 - /opt/Adobe/Reader9/Reader/intellinux/bin/acroread: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Martin Mokrejš 2013-09-23 14:00:06 UTC]

I recently installed a pure 64-bit amd64 machine. However, acroread seems to require 32-multilib.

$ acroread
/opt/Adobe/Reader9/Reader/intellinux/bin/acroread: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
$


emerge adviced to install www-plugins/nspluginwrapper and I can confirm that through firefox browser I can open PDF files (provided the same app-text/acroread-9.5.5 is used as the underlying tool).


I tried to include manually the misisng library in the path but that fails:

$ LD_LIBRARY_PATH=/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3 acroread somefile.pdf 
/opt/Adobe/Reader9/Reader/intellinux/bin/acroread: error while loading shared libraries: libstdc++.so.6: wrong ELF class: ELFCLASS64
$

[Comment 1 Ben Kohler 2013-09-24 13:21:59 UTC]

app-text/acroread is masked on no-multilib profiles, how did you manage to get it installed?

[Comment 2 Martin Mokrejš 2013-09-24 16:10:12 UTC]

Well, I just used --autounmask-write to allow emerge to install it.

Damn, I just felt into the trap just because I followed

http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=6

notably, "If you want to have a pure 64-bit environment, with no 32-bit applications or libraries, you should use a non-multilib profile". Doh, there should be a bold section warning users that lots of stuff will anyway force them sooner or later on to install:

# grep x86 /var/log/emerge.log | grep AUTOCLEAN | awk '{print $4}' | sort| uniq
app-emulation/emul-linux-x86-baselibs:0
app-emulation/emul-linux-x86-db:0
app-emulation/emul-linux-x86-gtklibs:0

app-emulation/emul-linux-x86-qtlibs:0
app-emulation/emul-linux-x86-soundlibs:0
app-emulation/emul-linux-x86-xlibs:0
#

Why acroread isn't happy with them? If it can't, you should not recommend non-multilib almost ever to a user. xpdf is gone from tree, okular pulls in awfull KDE dependencies which I am not going to accept anymore, and there is probably nothing else left as a usable PDF reader. What am I missing?

[Comment 3 Ben Kohler 2013-09-24 16:14:18 UTC]

I think the only thing missing is that when you read the paragraph about "with no 32-bit applications", you didn't realize how many 32-bit-only applications there actually are.  And acroread is one of them.  From what I see with new users, 95% of them who pick no-multilib end up regretting it, so I do agree that a scarier warning would be helpful.

For some more minimal readers, try zathura (with zathura-pdf-popper or zathura-pdf-mupdf) or mupdf.

[Comment 4 Martin Mokrejš 2013-09-24 17:14:07 UTC]

But, first of alll I thought that linux kernel now has an option to execute 32-bit binaries staright away. Second, why couldn't there be just a 32-bit copy of the libc++.so in the app-emulation packages?


I am running 3.10.10 kernel with:

CONFIG_64BIT=y
CONFIG_IA32_EMULATION=y
CONFIG_X86_X32=y


The help in "make menuconfig" says I will need >=binutils-2.22 with elf32_x86_64 enabled. Maybe that is the problem with my system?


# binutils-config 
Usage: binutils-config [options] [binutils profile]

General Options:
  -c, --get-current-profile  Print current profile
  -l, --list-profiles        Print a list of available profiles
  -u, --uninstall            Remove all signs of specified target
  -d, --debug                Execute with debug output

General Cruft:
  --linker <linker>          Switch to specified linker (if supported)

Arch Specific Cruft:
  --amd64                    Install extra amd64 links (x86_64)
  --arm                      Install extra arm links (arm/armeb)
  --mips                     Install extra mips links (mips/mipsel)
  --x86                      Install extra x86 links (i[3-6]86)

Profile names are of the form:  <CTARGET>-<binutils version>
For example:                    i686-pc-linux-gnu-2.15.92.0.2

For more info, please see binutils-config(8).
# binutils-config -c
x86_64-pc-linux-gnu-2.23.2
# 

So should there be somewhere "--amd64" appended?

The kernel can run the 32bit binaries, but the supporting shared libs don't exist since your toolchain pieces were built without multilib functionality.  Specifically here, the 32bit libstdc++ is provided by a multilib-enabled gcc.

You *may* still have gcc-4.6.3 built with multilib available, you can try switching to that via gcc-config.  But I suspect you may be past the point of no return (to multilib) here.

There's no bug here, please try one of our support venues like forums or IRC if you need further help with this no-multilib situation.
