the current up to date glibc-common for rhel6.4 ( i am using CentOS here) is
so it is up to date ( mostly)
it just has some OLD packages in it
the current gcc ( gcc-4.4.7-3.el6.x86_64.rpm -- centos 6.4 )
should be in there
but a older version IS ( likely for rhel6.3 or 6.2 )
also for installing the development "tree"
it is RECOMMENDED to install the " Development " group with yum
yum groupinstall "Development Tools"
" yum --help" and " man yum "
gcc dose not live in a vacuum it needs a lot of other programs ( like Autotools and the source code headers " *.h" )
I take it your background is with using Microsoft's " Visual Studio "
the linux gcc compiler is VERY VERY different
-- a lot easier to use from the terminal , i almost NEVER use a GUI
in windows there is a thing called " DLL HELL "
with Linux it is a bit different it is "Prerequisite hell"
call red hat , i will bet that they instruct you to dump the local repo and sync it to the current
