What mdk 8.2 are you using? because my standard
edition box is missing some crucial things.
Amongst them the gcc-cpp-2.96-0.76 .mdk rpm
that is needed to run gcc.
On cd 1 there are make and gcc rpm's. I got the
missing rpm's from a dvd that came with a magazine
maybe you can get yours at www.rpmfind.net
are you sure all of the mentioned rpm are not installed?
check it; rpm -qa |grep -i nameofonstalledrpm
