Problem with shared dynamic library files
I am having a major problem. Most of the commands that i am running on my centos 5 system is giving the error of type:

Code:
<dynamic shared library file>:open failed: No such file or directory

For example:
libgcc_s.so.1: open failed: No such file or directory

How can i solve this?

Code:
[root@fred ~]# ldd /bin/rpm
        librpm-4.4.so => /usr/lib64/librpm-4.4.so (0x0000003a52e00000)
        librpmdb-4.4.so => /usr/lib64/librpmdb-4.4.so (0x0000003a52a00000)
        libselinux.so.1 => /lib64/libselinux.so.1 (0x0000003a57a00000)
        librpmio-4.4.so => /usr/lib64/librpmio-4.4.so (0x0000003a51a00000)

        libsqlite3.so.0 => /usr/lib64/libsqlite3.so.0 (0x0000003a51e00000)
        libelf.so.1 => not found
        libbeecrypt.so.6 => /usr/lib64/libbeecrypt.so.6 (0x0000003a52200000)
        libm.so.6 => /lib64/libm.so.6 (0x0000003a50600000)
        libdl.so.2 => /lib64/libdl.so.2 (0x0000003a50a00000)
        libz.so.1 => /usr/lib64/libz.so.1 (0x0000003a51200000)
        librt.so.1 => /lib64/librt.so.1 (0x0000003a51600000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003a50e00000)
        libbz2.so.1 => /usr/lib64/libbz2.so.1 (0x0000003a63000000)
        libc.so.6 => /lib64/libc.so.6 (0x0000003a50200000)
        libelf.so.1 => not found
        libsepol.so.1 => /lib64/libsepol.so.1 (0x0000003a57e00000)

        libgcc_s.so.1 => not found
        libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003a62800000)
        libgcc_s.so.1 => not found
        libgcc_s.so.1 => not found

When i simply run rpm i get the error:

Code:
[root@fred ~]# rpm
rpm: error while loading shared libraries: libelf.so.1: cannot open shared object file: No such file or directory

Which is obvious from the output of ldd

The output of locate command suggests that the libraary file is indeed missing from the system:
Code:
[root@fred ~]# locate libgcc_s.so.1
[root@fred ~]#

Is LD_LIBRARY_PATH set to some odd-ball directory?
# 5  
Old 12-19-2009
Code:
[root@fred keross]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/opt/nable/usr/lib

Also, I have a file named local.conf in /etc/ld.so.conf.d/ directory, the contents of which is:

Code:
[root@fred keross]# cat /etc/ld.so.conf.d/local.conf
/usr/lib64:/lib:/lib64:/usr/lib

Do i still need to set LD_LIBRARY_PATH?
What do you mean by odd-ball directory?
I don't have a value set for LD_LIBRARY_PATH

Code:
[root@fred keross]# echo $LD_LIBRARY_PATH

[root@fred keross]#

Try fixing up the symbolic links for libgcc_s and libelf. Looks like /lib64/libgcc_so.1 and /usr/lib64/libelf.so.1 have gone missing. These are also symbolic links which point to the actual shared library.

Can you elaborate a bit the process of fixing.
