Linux – Linker error while installing Oracle 11g on Fedora 18

I have to teach database programming against Oracle DB using C/C++ on Linux. So first step is to install Oracle 11g on Linux.

Machine config :
HOST: Windows 8 Enterprise 64 bit
Guest: Fedora 18 XFCE edition 32 bit using Virtual Box 4.2.10

I'm using this link as a guide.

I have completed all steps till './runInstall' step where I get an error in the linking phase:

The following is an extract from the log file in '/u01/app/oraInventory/logs':

[oracle@localhost logs]$ tail -n 25 installActions2013-03-31_03-14-24PM.log

How to fix this error?

Are there any other ways to show Oracle DB programming using c++?

Let me know if any other info is needed.
