libstdc++.s0.5: cannot open shared object file: No such file

[xanphi]

Installing athlon stage 1 on a7m266d mobo, 2x1900mp. I got through installing X...... system locked up while I was attempting to emerge links. After a hard reboot almost anything I try results in the following error message:

/usr/bin/python: error while loading shared libraries: libstdc++.s0.5: cannot open shared object file: No such file or directory


any ideas as to whats wrong and how to fix?
help!

[azcoder]

in /usr/lib do a
ls libstd*.

See if you get a libstdc++.s0.5.

If not, you need to get one. I think it is part of the standard gcc build, so try: emerge gcc.

Good Luck

[xanphi]

Thanks for pointing me in the right direction.... I tried emerge gcc to get yet again "libstdc++.s0.5: cannot open shared object file: No such file" . So I started poking around on a couple of HD's with failed attempt of this install and found libstdc++.s0.5 and libstdc++.s0.5.0.3 which is what the previous points to (or visa versa) + libgcc_s.so.1, et al, which was also missing in a gcc temp build dir of some sort. After replacing these files emerge worked fine and I re-emerged gcc to be on the safe side. All seem well in Gentoo land.

thanks again

hi
please help

my topic says it all

i made a booboo


when i try emerge
i get this

Code: Select all

root@jt lib # emerge
/usr/bin/python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

anyideas?

[slestak]

type ldconfig, it'll take care of it.

[mahir]

it does..

i type ldconfig
and i get the same error

i cant env-update
i cant man
i cant anything!
i cant emerge


what have i done!? (

[slestak]

hmmm. that took care of my prob. same error as yours. head over to irc.freenode.net #gentoo and someone there may be able to help.

Re: Python-2.3.3 erroring followed by not being able to emerge or do anything with Portage for that matter.......

nano -w /etc/env.d/05gcc

added at bottom of file...

LD_LIBRARY_PATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3"
(the last part is what you need to make sure says 3.3.3....it probably still reads your prior version)

then ran...

source /etc/profile

then...

LD_LIBRARY_PATH=/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3 env-update

That should fix your problem.

[rdx]

oh dear.. what a critical situation if you get this error and can't do anything many many thanks for the solution, it saved us alot of time and nerves

but anyway, portage should really care about issues of that kind.. it can't be that portage breaks the entire system this way.. it seems the hardened project is really necessary it broke my mail server which depends on mysql..

well, everything's fine again, i'm happy so what..

[UncleTom]

The fun never stops... If you also get the following error

Code: Select all

# gcc
Could not run/locate "gcc"

after applying tekM's solution, then see http://forums.gentoo.org/viewtopic.php?p=900846#900846 for the next steps.

[araemo]

LD_LIBRARY_PATH=/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3 env-update

That should fix your problem. :D

THANK YOU THANK YOU THANK YOU. I edited the files, as I found complete instructions for in other threads, ran ldconfig, sourced /etc/profile, (Which then prevented me from running env-update at all, it couldn't find it) and tried it again as root(instead of sudo).. still getting the same error running env-update. I didn't know enough about how shared libraries work to think of doing that myself. when the instructions are: 1: edit files to show 3.3.2 instead of 3.2.3, 2: ldconfig, 3: env-update.. and env-update errors with the same error as everything else.. well, yippee. :P

[cayenne]

type ldconfig, it'll take care of it.

I did this and got:

ldconfig
ldconfig: /usr/lib/libstdc++-libc6.1-1.so.2 is not a symbolic link

Not sure what this means...??

Should I still follow the editing parts of this thread?

Thanx,

Re: Python-2.3.3 erroring followed by not being able to emerge or do anything with Portage for that matter.......

nano -w /etc/env.d/05gcc
LD_LIBRARY_PATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3"

This almost worked for me, but still gave me problems. In the end it turned out that many of the other paths mentioned in this file were wrong.

My final file became:

Code: Select all

PATH="/usr/i686-pc-linux-gnu/gcc-bin/3.3"
ROOTPATH="/usr/i686-pc-linux-gnu/gcc-bin/3.3"

LDPATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2"
LD_LIBRARY_PATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2"

The PATH, ROOTPATH, etc. all said the old values and needed to be changed as well...

thanx for the great post... saved me from major stress...

I did this and got:

ldconfig
ldconfig: /usr/lib/libstdc++-libc6.1-1.so.2 is not a symbolic link

Not sure what this means...??

Try this and see if it fixes your problem:

Code: Select all

mv /usr/lib/libstdc++-libc6.1-1.so.2 /usr/lib/libstdc++-libc6.1-1.so.2.OLD
ln -s /usr/lib/libstdc++-libc6.1-1.so.2 /usr/lib/libstdc++-libc6.2-2.so.3

[afreeman]

Had the exact same problem: 'emerge -u portage' croaked on gawk with the same error as original poster.

After tweaking the recommendations here a bit (my paths were 3.3.2), everything works nicely.

Thanks for your help guys.

[Walmarde]

I'd get the same f****** probleme and i finally fixed it ! thnx a lot guys !

but my prbleme was a little bit different

in /etc/env.d/05gcc i had to change all the version from :

PATH="/usr/i586-pc-linux-gnu/gcc-bin/3.2"
ROOTPATH="/usr/i586-pc-linux-gnu/gcc-bin/3.2"
MANPATH="/usr/share/gcc-data/i586-pc-linux-gnu/3.2/man"
INFOPATH="/usr/share/gcc-data/i586-pc-linux-gnu/3.2/info"
CC="gcc"
CXX="g++"
LDPATH="/usr/lib/gcc-lib/i586-pc-linux-gnu/3.2.3"
LD_LIBRARY_PATH="/usr/lib/gcc-lib/i586-pc-linux-gnu/3.2.3/"

to :

PATH="/usr/i586-pc-linux-gnu/gcc-bin/3.3"
ROOTPATH="/usr/i586-pc-linux-gnu/gcc-bin/3.3"
MANPATH="/usr/share/gcc-data/i586-pc-linux-gnu/3.3/man"
INFOPATH="/usr/share/gcc-data/i586-pc-linux-gnu/3.3/info"
CC="gcc"
CXX="g++"
LDPATH="/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.2"
LD_LIBRARY_PATH="/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.2/"

after that i had to do:

source /etc/profile

and

LD_LIBRARY_PATH=/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.2 env-update


Everything works fine for me now

[WebSel]

Ok, I've just updated portage and ran into the same problem.
It didn't work for me what was written, i did the changes anyway!

The last step i needed was:
edditing the /etc/ld.so.conf
Change the lines into:
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2
or for intell:
/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.2

Now run ldconfig
Now env-update is working, now run env-update, check the file again as it is changed by env-update if it still reads the correct values.
If it is changed back you need to change more in the /etc/env.d directory to the correct path.

Ok here a proper and clear way about fixing this problem on a pentium server.

Action done:

Code: Select all

# emerge -U portage

This results finaly in the following error:

Code: Select all

Could not run/locate "gcc"
make[1]: *** [fascist.o] Error 1
make[1]: Leaving directory `/var/tmp/portage/cracklib-2.7-r8/work/cracklib,2.7/cracklib'
make: *** [all] Error 2

!!! ERROR: sys-libs/cracklib-2.7-r8 failed.
!!! Function src_compile, Line 44, Exitcode 2
!!! (no error message)

try this:

Code: Select all

# emerge --help
/usr/bin/python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

This mean's your library path is screwed because of an update of the compiler libraries. There is now way to fix this as env-update isn't working either.

Now let's have a look at this. Start off where the libraries paths's are kept:

Code: Select all

keystone root # cat /etc/ld.so.conf 
# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory
/usr/local/lib
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3

Now let's check this out if the 3.2.3 directory really excists.

Code: Select all

# ls -sla /usr/lib/gcc-lib/i686-pc-linux-gnu/
total 4
   1 drwxr-xr-x    3 root     root           72 Apr  9 12:24 .
   1 drwxr-xr-x    3 root     root           88 Sep 12  2003 ..
   3 drwxr-xr-x    5 root     root         2160 Apr  9 12:24 3.3.2

Nope it's a typo, ok great let's fix this so we can use env-update again. we do this by changing the path into the correct path.

Code: Select all

# nano /etc/ld.so.conf 

Ok change the line of:

Code: Select all

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3

into

Code: Select all

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2

Save the file, and run ldconfig

Code: Select all

# ldconfig

Ok test it with for example:

Code: Select all

# emerge --version

No more :/usr/bin/python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
errors? GOOD!
Now fix it for real so that env-update will do it's work correct. You need to edit the /etc/env.d/05gcc file and correct all the path's into 3.3
Old:

Code: Select all

PATH="/usr/i686-pc-linux-gnu/gcc-bin/3.2"
ROOTPATH="/usr/i686-pc-linux-gnu/gcc-bin/3.2"
MANPATH="/usr/share/gcc-data/i686-pc-linux-gnu/3.2/man"
INFOPATH="/usr/share/gcc-data/i686-pc-linux-gnu/3.2/info"
CC="gcc"
CXX="g++"
LDPATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3"

New:

Code: Select all

PATH="/usr/i686-pc-linux-gnu/gcc-bin/3.3"
ROOTPATH="/usr/i686-pc-linux-gnu/gcc-bin/3.3"
MANPATH="/usr/share/gcc-data/i686-pc-linux-gnu/3.3/man"
INFOPATH="/usr/share/gcc-data/i686-pc-linux-gnu/3.3/info"
CC="gcc"
CXX="g++"
LDPATH="/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2"

After saving the file run the env-update command and for a final check check the /etc/ld.so.conf file if the path's are still correct and now run
emerge -U portage again to finish the job.

[Muddy]

I was receiving this

Code: Select all

# emerge -U perl 
python2.2: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

After being a bonehead rebooted my server (forgetting was running an "emerge -U portage")

So I had to do a

Code: Select all

nano -w /etc/ld.c

and add the following

Code: Select all

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/

Now it's still screwed up but this problem is solved.

[L1A]

As you have guessed by now your version of gcc has changed and screwed everything up. And its a sneaky change 3.2.3 to 3.3.2 so it looks like a typo.
After reading the first few comments in ld.so.conf I did some poking around.
# ld.so.conf autogenerated by env-update; make all changes to
# contents of /etc/env.d directory

So I edited 2 files.
/etc/env.d/05gcc
/etc/env.d/gcc/config
And updated everything that had a 3.2.3 to the new value of 3.3.2
NOW you can run env-update and ldconfig.
And everything should work.
But I also hang garlic over the computer.

thank you very much to the boffins in here, you guys helped me a great deal! have a super day!

Hello!
Reviving old thread.

I emerged gcc-3.3.5-r1 and had gcc-3.3.2-r5 before.
It broke nearly everything I think

I followed many advice from this thread and didn't fully succeed, but the system is "kind of" usable again.

I can't start new KDE applications so I am a little scared of a reboot.

Here it is:

I emerged gcc and immediately had problems with libstdc++.so.5 missing.
None of the above suggestion solved it so I made a symlink
/usr/lib/libstdc++.so.5 -> libstdc++.so.2.8.0

Now I can use portage without errors it seems, but KDE will not start new applications. I try kontact...

Code: Select all

jonas@jw jonas $ kontact
kontact: /usr/X11R6/lib/libstdc++.so.5: no version information available (required by kontact)
kontact: /usr/X11R6/lib/libstdc++.so.5: no version information available (required by kontact)

jonas@jw jonas $ 

And I didn't actually expect it to work either. But I don't know how to fix it, since there is nothing looking like it on the system. (find /usr /lib -name libstdc++* returns several files but no libstdc++.so.5)
BTW /usrX11R6/lib is a symlink to ../lib.


That's one of the problems, I don't have /usr/lib/libstdc++.so.5

Next problem is, I no longer have any g++ file.

Code: Select all

jw bin # g++
g++: No such file or directory
jw bin #

and when I try to emerge xmms, it fails with the error

Code: Select all

checking for i586-pc-linux-gnu-g++... g++
checking whether we are using the GNU C++ compiler... no
checking whether g++ accepts -g... no
checking how to run the C++ preprocessor... /lib/cpp

!!! Function econf, Line 485, Exitcode 0
!!! econf failed
!!! If you need support, post the topmost build error, NOT this status message.

jw jonas #

And that "... ...xmms-jack/config.log" only says it couldn't find any g++. And I don't either. There isn't any.
I thought emerging gcc would pull it in. And I promise I didn't have nocxx in the USE-flags.
After emerging gcc three times and glibc between first and second emerge gcc I am a little stuck.

I don't have the courage to reboot right now as I am not shure it will come up correctly.

Anyone help?

[jonaswidarsson]

I was using ccache before the gcc upgrade, but since I had errors I have now (before above post) removed it from my path and taken it out of FEATURES in /etc/make.conf

Is there anything I can blindly try to emerge to see if it fixes any of these two issues?

[Maedhros]

Have you seen this sticky in Portage & Programming?

[jonaswidarsson]

Have you seen this sticky in Portage & Programming?

No, I hadn't, but I found something very strange.
I compared the output of "gcc -v" on this and another computer.

the server:

Hmm.. the f77 is not interesting in this case I believe, and I actually disabled it with USE-flag -fortran to speed up an emerge. But otherwise the use flags for the gcc ebuild are identical on those systems.

WHY is c++ missing? I don't have any dangerous use-flags set.

I post this now while keeping on searching.
