Friends

I have an IBM Power System5 with RHEL 4.5 installed on it.
I am trying to install Oracle10g (PPC64) on it last week and i have been repeatedly getting the following errors:

/usr/bin/ld: cannot find /usr/lib64/libpthread_nonshared.a
collect2: ld returned 1 exit status
genclntsh: Failed to link libclntsh.so.10.1
Output of $ORACLE_HOME/install/make.log file:
In $ORACLE_HOME/install/make.log file.(Installation Log file)

I posted this error in oracle Forums and got the reply to check all Packages required for Oracle.(Esp C/C++ Runtime env).

I downloaded the C/C++ packages from below site:

IBM XL C/C++ Advanced Edition V7.0.1 for Linux Runtime Environment Component and XL Optimization Libraries component.

You can download these components at:

(http://www-1.ibm.com/support/docview.wss?uid=swg24007906)

IBM XL C/C++ Advanced Edition V7.0.1 for Linux Runtime Environment Component is available free of cost and without any license requirements on this site.

Source : http://download.oracle.com/docs/cd/B14099_19/lop.1012/install.1012/install/reqs.htm#BABGCBGD

But i am unable to find the Advanced C/C++ Run time libraries as the above link(second one) says this is available for RHEL 5.2 and above.

I am at cross roads now. Not sure how to proceed. Would i be reuired to upgrade the OS or does anyone have the libraries for RHEL4.5?

Please assist me.

Thanks
