now as root
>root [ ~ ]# ldconfig
ldconfig: /usr/lib/libstdc++.so.6.0.14-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

>root [ ~ ]# cat /etc/ld.so.conf
# Begin /etc/ld.so.conf

/usr/local/lib
/opt/lib

# End /etc/ld.so.conf
# Begin gnome addition to /etc/ld.so.conf

/opt/gnome-2.30.2/lib

# End gnome addition
# Begin qt addition to /etc/ld.so.conf

/opt/qt/lib

# End qt addition
# Begin qt addition to /etc/ld.so.conf

/opt/qt/lib

# End qt addition   

i thought its not proper so i edited as like  below:i took back up  ld.so.conf.[as ld.so.conf.org]

and new ld.so.conf as below:

root [ /etc ]# cat ld.so.conf
# /etc/ld.so.conf

/lib
/usr/lib
/usr/local/lib
/var/lib
/opt/lib
/opt/qt/lib
/opt/gnome-2.30.2/lib

# End

>root [ /etc ]# ldconfig
result:
ldconfig: /usr/lib/libstdc++.so.6.0.14-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

i didnt reboot the system
