RHEL 7 : PRVF-7532 : Package "compat-libstdc++-33(x86_64)" is missing on node

While installing oracle 11204 on RHEL 7,I am getting below warring in the pre check step.

Error:

PRVF-7532 : Package "compat-libstdc++-33(x86_64)" is missing on node "Node1"
- Cause:  A required package is either not installed or, if the package is a kernel module, is not loaded on the specified node.
Action:  Ensure that the required package is installed and available.

But the above package is not there in the RHEL7 CD.

So i ignored it and stated installation.

During mid of installation I got the below warning as well.

Error:

INFO: /usr/bin/ld: warning: -z lazyload ignored.
/usr/bin/ld: warning: -z nolazyload ignored.

Exception Severity: 1

Then I ignored this error and continued,since i am not going to use Oracle EM product.

but when i apply the patch set i didn't encounter any error during Relink.

So i think this issue can be ignorable.
