Hi,

I encounter the following problem since my recent

Code:
emerge -uvDN world
:

For some strange reason all -bin packages (especially: net-im/skype, www-client/firefox-bin, mail-client/thunderbird-bin) are not starting anymore and give me the following error when trying to start them from a shell:

Code:
rob@frostmourne ~ $ skype
./skype: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory


I tried running a revdep-rebuild and tried fix_libtool_files.sh, unluckily none of it helped. Even tried to unmerge/re-emerge the affected ebuilds didn't help anything.

You'll find my corresponding emerge --info here: http://pastebin.com/h2VuqAqF

Thanks in advance for any help.

Regs,
Rob

PS: My previous gcc-version was 4.4.4-r2, which was emerged on 21-Nov-2010.

Baer,

libstdc++.so.6 is a piece of gcc-3, which Gentoo has not used for a long time.
Try
Code:
emerge sys-libs/libstdc++-v3

That reminds me:

Code:
rob@frostmourne ~ $ locate libstdc++.so.6
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.4.5/libstdc++.so.6
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.4.5/libstdc++.so.6.0.13
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.4.5/32/libstdc++.so.6
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.4.5/32/libstdc++.so.6.0.13


It seems that libstdc++.so.6 is already available.

NeddySeagoon, I think you've mixed it up with libstdc++.so.5, which indeed is at gcc 3.3.

www-plugins/google-talkplugin has the same issue. The 32-bit version of the library is not in the library search path. I fixed the issue by adding /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/32 to ld.so.conf via an env.d file. It seems like this should be done by the gcc package since all of the other 32-bit paths are already adding to the LDPATH variable by baselayout.

/etc/env.d/99mutlilib-libstdc++
Code:
LDPATH="/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/32"

Hey guys I just wanted to say I actually get the same exact error as Baer does. I also encountered the same problem after running

Code:
 
$ sudo emerge -uvDN world


In fact I even tried to re-emerge gcc-4.4.5 (latest one I had), but I was not able to re-emerge gcc-4.4.5. Every time I run

Code:
 
$ sudo emerge sys-devel/gcc


it just tries to emerge gcc-4.6.0 (and I do not want this version) and I am having trouble, because I added it in /etc/portage/package.mask, but of course that did me no good.

I tried to download libstdc++.so.6 and create a sym link in /usr/lib/, which somewhat worked, no longer was I receiving this error:

Code:

./skype: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory


I actually started to receive a new error:

Code:

$ skype
./skype: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./skype)


I tried to do some googling, and yet I still came up with nothing, I tried running revdep-rebuil and tried fix_libtool_files.sh, and yet that did absolutely nothing. Therefore I tried to go ahead and just emerge gcc-4.6.0, because obviously there's something wrong with gcc here. But that also did me no good because i ended up with another error:

Code:

* ERROR: sys-devel/gcc-4.6.0 failed (compile phase):
 *   emake failed with bootstrap-lean
 *
 * Call stack:
 *     ebuild.sh, line   56:  Called src_compile
 *   environment, line 4852:  Called toolchain_src_compile
 *   environment, line 5446:  Called gcc_src_compile
 *   environment, line 3038:  Called gcc_do_make
 *   environment, line 2826:  Called die

 *       emake LDFLAGS="${LDFLAGS}" STAGE1_CFLAGS="${STAGE1_CFLAGS}" LIBPATH="${LIBPATH}" BOOT_CFLAGS="${BOOT_CFLAGS}" ${GCC_MAKE_TARGET} || die "emake failed with ${GCC_MAKE_TARGET}";


Here is the output of

Code:

sudo emerge --info =sys-devel/gcc-4.6.0

As this is really not my main concern, because I really just want to stick with gcc-4.4.5, because this is the latest stable gcc, but I just want to be able to re-emerge gcc-4.4.5 to fix the issue that both Baer and I are experiencing:

Code:

$ skype
./skype: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory


All help will be appreciated, thanks so much!

Also here is my output of

Code:

* Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries using libstdc++.so.6
 * will be emerged.

 * Collecting system binaries and libraries
 * Found existing 1_files.rr
 * Checking dynamic linking
 * Found existing 3_broken.rr.
 * Assigning files to packages
 * Found existing 4_raw.rr
 * Cleaning list of packages to rebuild
 * Found existing 4_pkgs.rr
 * Assigning packages to ebuilds
 * Found existing 4_ebuilds.rr
 * Evaluating package order
 * Warning: Failed to resolve package order.
 * Will merge in arbitrary order
Possible reasons:
- An ebuild is no longer in the portage tree.
- An ebuild is masked, use /etc/portage/packages.keyword
and/or /etc/portage/package.unmask to unmask it
.....
 * All prepared. Starting rebuild
emerge --oneshot --pretend --verbose  media-gfx/gimp:2
x11-drivers/xf86-video-ati:0
x11-drivers/xf86-video-intel:0
x11-drivers/xf86-video-nouveau:0

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/libdrm-2.4.24[video_cards_nouveau]".
!!! One of the following packages is required to complete your request:
- x11-libs/libdrm-2.4.25 (Change USE: +video_cards_nouveau)
(dependency required by "x11-drivers/xf86-video-nouveau-0.0.16_pre20110323" [ebuild])
(dependency required by "x11-drivers/xf86-video-nouveau:0" [argument])
 * revdep-rebuild failed to emerge all packages.
 * you have the following choices:
 * - If emerge failed during the build, fix the problems and re-run revdep-rebuild.
 * - Use /etc/portage/package.keywords to unmask a newer version of the package.
 *   (and remove 5_order.rr to be evaluated again)
 * - Modify the above emerge command and run it manually.
 * - Compile or unmerge unsatisfied packages manually,
 *   remove temporary files, and try again.
 *   (you can edit package/ebuild list first)
 * To remove temporary files, please run:
 * rm /var/cache/revdep-rebuild/*.rr


Not sure why I am getting this error, I installed nvidia drivers as a binary in gentoo...so I should not have to add ">=x11-libs/libdrm-2.4.24" that in my package.use file or have to add 'VIDEO_CARDS="nouveau"' in make.conf.

well for whatever reason, these were installed

x11-drivers/xf86-video-ati:0
x11-drivers/xf86-video-intel:0
x11-drivers/xf86-video-nouveau:0

so i removed them, and so now this is my new output of

Code:

$ sudo revdep-rebuild --library libstdc++.so.6 -- -p -v


Code:

 * Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries using libstdc++.so.6
 * will be emerged.

 * Collecting system binaries and libraries
 * Generated new 1_files.rr
 * Checking dynamic linking
[ 100% ]                 

 * There are no dynamic links to libstdc++.so.6... All done.


so this did not fix the issue

okay so I guess gcc-4.6.0 was actually unmasked in package.keywords which was really weird cause I don't remember ever autounmasking it. Anyways, I went ahead and removed that from package.keywords, and then ran

Code:

$ sudo emerge -uNDva world


and now everything works well...so basically just reinstall gcc, and everything should be g2g

Hope this helps...

in my case gcc-4.4.5 was installed and solution was the next:

# cd /lib32
# ln -s /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.5/32/libstdc++.so.6 libstdc++.so.6

Thanks for this, taras-lao! Sems to be an error in the post-install routine? I may well be wrong though....

It may work, but that is wrong.
There should be no link in /lib32 and the next time you upgrade gcc, you'll likely have problems again.

I'm watching this. I'm emergind libstdc++, despite having the libs already installed, the package wasn't. I thought this libraries came with gcc.
Anyways, if emerging don't work, I'll try symlinking the 64 bit version to the 32bit folder. amd64 multilib here.
Besides Skype, Eclipse + ADT also complained about this specific lib missing.

edit: symlinking didn't work as expected. The path was wrong. I need the link to be at /usr/lib32, not /lib32. Anyways, that didn't work either, I need the 32 bit version of the library. Tried symlinking libstdc++.so.5 to .so.6, but it didn't work too, ADT throws these errors:

[2011-08-09 17:44:42 - XXXXX] /home/spidey/android-sdk-linux_x86/platform-tools/aapt: /usr/lib32/libstdc++.so.6: version `CXXABI_1.3' not found (required by /home/spidey/android-sdk-linux_x86/platform-tools/aapt)
[2011-08-09 17:44:42 - XXXXX] /home/spidey/android-sdk-linux_x86/platform-tools/aapt: /usr/lib32/libstdc++.so.6: version `GLIBCXX_3.4' not found (required by /home/spidey/android-sdk-linux_x86/platform-tools/aapt)

Aparently, I need the updated version, and it's missing.

Could someone run this to help us out?
equery b /usr/lib32/libstdc++.so.6

It will return the package that "owns" the library.

edit2: found who owns libstdc++.so.5: sys-libs/libstdc++-v3-3.3.6-r1
Like I said previously, I didn't had this package 'till a couple minutes earlier, and I'm sure that emerge depclean will remove it. What we need is the updated package.

edit3: found the problem: https://bugs.gentoo.org/show_bug.cgi?id=377633
Solution: https://bugs.gentoo.org/show_bug.cgi?id=377633#c9
