[gentoo-user] emerge broken - libstdc++.so.5

[gentoo-user] emerge broken - libstdc++.so.5

[Mark Knecht]

Hi,
   I've been working through some updates on my wife's machine and now
it appears emerge itself has been broken:

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

   gcc and glibc updates were part of what was going on.

   I have some other Gentoo machines here at home if I need to copy something.

   How can I recover?

   First time in 3-4 years of running Gentoo that anything like this
has happened!

Thanks,
Mark

Like many things in life this pain seems to be somewhat self
inflicted, I suppose. More into.

After emerging gcc-3.4.6 I had troubles with the gcc-config stuff so I
removed gcc-3.3.6. However it appears that removing 3.3.6 removed
libstdc++ also. I updated slocate's database and saw that the only
libraries with that name are gone now:

dragonfly ~ # slocate libstdc++.so.5
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5.0.7
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5
dragonfly ~ # updatedb
dragonfly ~ # slocate libstdc++.so.5
dragonfly ~ #


More info:

It seems that my AMD64 machine has a number of these:

I have never done it but don't worry, you are definitely not alone.  I
guess that is why the page is there.  ;-)

Hi,
   For a few moments I thought this might be the problem, and I though
I might end up on the Wall of Shame (tm) but in fact this doesn't
solve my problem since it doesn't install libstdc++.so.5

dragonfly ~ # gcc-config -l
 [1] i686-pc-linux-gnu-3.4.4 *
 [2] i686-pc-linux-gnu-3.4.4-hardened
 [3] i686-pc-linux-gnu-3.4.4-hardenednopie
 [4] i686-pc-linux-gnu-3.4.4-hardenednopiessp
 [5] i686-pc-linux-gnu-3.4.4-hardenednossp
 [6] i686-pc-linux-gnu-3.4.6
 [7] i686-pc-linux-gnu-3.4.6-hardened
 [8] i686-pc-linux-gnu-3.4.6-hardenednopie
 [9] i686-pc-linux-gnu-3.4.6-hardenednopiessp
 [10] i686-pc-linux-gnu-3.4.6-hardenednossp
dragonfly ~ # source /etc/profile
dragonfly ~ # updatedb
dragonfly ~ # slocate libstdc++.so.5
dragonfly ~ #

dragonfly ~ # eix libstd
eix: error while loading shared libraries: libstdc++.so.5: cannot open
shared object file: No such file or directory
dragonfly ~ #


Do I need to do the same tar install of libstdc++ from the website
listed in the Gentoo Wiki you pointed me at?

On my AMD64 machine I can see where this comes from:

lightning ~ # equery belongs /usr/lib64/libstdc++-v3/libstdc++.so.5
[ Searching for file(s) /usr/lib64/libstdc++-v3/libstdc++.so.5 in *... ]
sys-libs/libstdc++-v3-3.3.4 (/usr/lib64/libstdc++-v3/libstdc++.so.5 ->
libstdc++.so.5.0.6)
lightning ~ #

But python won't run any of this stuff on this machine since it cannot
get this library.

What am I not understanding? Seems like maybe I need to go back to an
install CD and get something but not sure what.

Thanks,
Mark

That's the file you need in order to save yourself.  Then follow the

I wanna say that about half my knowledge I get from fixing things that
have gone wrong...  okay, things that have gone wrong because of a
misintended command from me.

So, do I get a friend on the wall of shame?  Or are we in denial?  ; )

Great to hear you got it working.

That's because the tarball pointed to from that page is for 3.4.x,
which contains libstdc++.so.6 - libstdc++.so.5 is the shared library
from gcc 3.3.x, which is not binary compatible with libstdc++.so.6 -
hence, to recover using the method described on that Wiki page, you
need to find a 3.3.x tarball.

Does anyone have one already that they can offer? If not, let me know
your -march and etc., and I will see if I can compile/upload one for
you.

Thanks James. The required tarball is on the above referenced page.
I'm downloading it now.
