Extproc fails to load: error in loading library libclntsh.so

Question

Hi all.
I've configured Net8 to call external procedures. When the application
(sqlplus) makes the connection to the listener, extproc fails to load
because of:
extprocSMSC: error in loading shared libraries
libclntsh.so.1.0: cannot open shared object file: No such file or directory
The library is there (actually, there is a link libclntsh.so ->
libclntsh.so.1.0),
has the correct permissions:
lrwxrwxrwx 1 root root 16 Oct 28 21:08 libclntsh.so ->
libclntsh.so.1.0
-rwxr-xr-x 1 oracle dba 4357729 Oct 16 16:05 libclntsh.so.1.0
The LD_LIBRARY_PATH contains the oracle lib directory:
:/u01/app/oracle/product/8.0.5/lib
Any idea ? Could this come from an incorrect compile/link of my dynamic
library ?
Vincent
P.S.

Issue definitely seems to be with your Oracle env setup and configuration. Having a symlink point to another symlink is not necessarily a problem.
So, just to be sure, can you confirm the 2 below:
1) You have installed the Oracle 32 bit client (full) and are using the libraries in the Client as part of the LD_LIBRARY_PATH for the OS user that is running the INFA processes. In other words your ORACLE_HOME (in .bash_profile) points to the CLIENT directory with the .so files..correct. You have confirmed this by su - as the OS user (e.g "oracle") and doing an echo on LD_LIBRARY_PATH. correct? if needed, I would even recommend using the FULL path to the 32 bit client directory.
2) You have confirmed that all .so files in the directory have permissions for the OS user that is running INFA processes. You can check this via ls -alt and confirming none of the .so files in question are restricted.
3) Also..is your OS user for the Oracle DB and INFA the same? Or do you have 2 different OS users?
