please stay current and install Fedora 20 FIRST
as to the "spell out your words"
googletranslate and bablefish do not work well on "text speek"
and typing in "text speek" is considered a bit "rude" and rather "CHILDISH"
it portrays the person as a teenager or preteen
NO boss wants to get a email in "text speek"
now as to installing gcc
it is a LOT more complicated than just installing ONLY the current gcc.rpm
gcc NEEDS a lot of other things
now with fedora 17 being UNSUPPORTED and will NEVER be updated some repo mirrors will have been removed but it should ( for now ) still work
yum groupinstall "Development Tools"
that will install the compiller and what it needs
BUT NOT any needed headers and librarys
