installing gcc on linux box running fedora

cc is the C compiler and CC is the c++ one (case sensetive) -- in some text file out there in some poorly named folder, you have to change the a line to tell the system to use whatever compiler you already have so you can install the new version. Unless you tampered with the fedora install, you already have g++ or gcc on that system.

Alternately, just replace the cc with g++ in that file (makefile or whatever it was).

I am no expert but I think g++ is a wrapper for many, many compilers including gcc? Either way, fedora should have a version of both and the preferred call is to g++.

gcc/g++ should stand alone (they rely on system libs and whatnots but these should exist and be set up if the compiler is present, which it will be unless you forcibly removed it during linux setup) -- all you should have to do is invoke g++ with all the source files and the include folder. However, most downloaded stuff needs a makefile to define non code things like environment vars and defines, so you often end up having to deal with the make mess.

you dont have to define cc as g++, but you *should*. I do not know how, there are 200 million little text files in linux that define how the OS does things, you have to find the right one and edit it. This is where you will have to look up the answer on a linux group.

Unfortunately, a new install generally requires a prior install, as gcc is written in c or c++ and so you need a compiler to compile the new version... or you will have to locate a binary package for it that matches your hardware/OS version.

However, g++ or gcc really, really should already exist. try making a hello world c++ program and then try
g++ hello.cpp
and you should get a binary file named a.out that you can execute (type a.out and it should run and print hello world) ... if you can do that, you already have a c++ compiler. Try it with gcc as well, same thing, if neither work, your ... in for a difficult time.
