error while loading shared libraries

Message

I had a power outage while installing a package and now when I run emerge sync (or emerge with any argument) I get this error.

/usr/bin/python2.2: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

I get similar errors with startx and env-update (diferent libraries).

It seems that the problem should be a fairly simple one. I have checked that file "libstdc++.so.5" exists and is in the PATH - this is the limit of my expertise in such matters. Any help to avoid reinstalling will be appreciated.

Have you tried /sbin/ldconfig (as root)?

excellent! ldconfig seems to have rectified most of the problems (thank you!), however it generated the following errors when I ran it.

gentoo root # ldconfig
ldconfig: /usr/lib/libgconf-1.so.1.0.3 is not an ELF file - it has the wrong
magic bytes at the start.

ldconfig: /usr/lib/libgconf-1.so is not an ELF file - it has the wrong magic
bytes at the start.

ldconfig: /usr/lib/libgconf-1.so.1 is not an ELF file - it has the wrong magic
bytes at the start.

ldconfig: /usr/lib/libgconf-gtk-1.so is not an ELF file - it has the wrong
magic bytes at the start.

ldconfig: /usr/lib/libgconf-gtk-1.so.1 is not an ELF file - it has the wrong
magic bytes at the start.

ldconfig: /usr/lib/libgconf-gtk-1.so.1.0.0 is not an ELF file - it has the
wrong magic bytes at the start.

I am wondering whether Gentoo has a mechanism for verifying or reinstalling installed packages?

No, gentoo doesn't verify installs. You can do something like

Code: Select all

emerge -e world

. Type

Code: Select all

emerge -evp world

to see it's outcome. Try

Code: Select all

man emerge

to see all the other options. There is also a portage howto on the documentation page: http://www.gentoo.org/doc/en/portage-user.xml

I have a very similar problem. I was upgrading from 1.4rc2 to 1.4rc4. I was following the upgrade manual and was upgrading portage (emerge -u portage). I left for work, thinking all should be fine until I get back. I do, and I was kicked out of XWindows without any kind of error message (I guess I should have known not to do that but...). I tried starting portage's upgrading again and it gave me that error message about python2.2 (except it didn't have /usr/bin in front of it). I tried /sbin/ldconfig. It doesn't say anything, it just ran for a couple seconds and returned me to the command prompt. I tried emerge -up portage and it still gave me the same error message. I went to /usr/lib/gcc-lib/i686-pc-...-gnu/3.2.2/ and tried ldconfig -l libstdc++.so.5 and it said that it wasn't a regular file. I noticed that there was a libstdc++.so.5.0.2 and I tried the same thing with that. It seemed to run with no problem. So, I tried emerge -up portage again and it said the same error message. Any other ideas? Thanks for the help.

I had a similar problem and managed to solve it !

first I did

Code: Select all

ldconfig -v | grep libstdc

There was nothing on my sick box, but on my working box got :-

libstdc++.so.5 -> libstdc++.so.5.0.2

Then I check /etc/ld.so.conf and found the following line was missing on the sick box :-

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.2

I added the above line then just ran

Code: Select all

ldconfig

as root, that seemed to fix it
