This IS RHEL5.8
so you DO have the REQUIRED support contract
and that gives you access to the red hat knowledge base
your first stop on solving something should be there
( you will have to login to red hat using the username and pass you set up when you bought the required license )
most likley there is a solution posted there
Can you advise where do I download the 32 bit compatibility library ?
HOW did you install "XAMPP"
yum should have pulled the needed things
you say you need "mySQL"
it IS ON THE VERY OLD red hat 5 install dvd
rhel5 came out in 07 so the version of MySQL on rhel5.8 is VERY OLD
is there a MUST USE NEED for using the old 5 series ??
you would be better off installing the current RHEL6.3
