gcc compiler installation

edit

1. Download and burn the DVD .iso for Fedora

Mount your DVD media:

mount -r /dev/cdrom /media/Fedora

Create file /etc/yum.repos.d/Fedora-Media.repo with the following content:

[c5-media]
name=Fedora-$releasever - Media
baseurl=file:///media/Fedora/
gpgcheck=0
enabled=0

Use your DVD to install "Development Tools"

yum --disablerepo=\* --enablerepo=c5-media groupinstall "Development Tools"

Other way is to mount Fedora DVD, and run system-config-packages in a terminal, check the packages you wanted to install under development-tools, then apply your change.

Hi! I hope this may help you, so there we go. As seeing in the wiki of gcc here http://gcc.gnu.org/wiki/InstallingGCC the /configure inside the source code is not supported so this is what we are going to do.
First we create a new directory

mkdir gcc-src
cd gcc-src

Now we should unzip that .tar.gz file

tar xzf path-of-tar-file/gcc-version.tar.gz

So as GCC has some prerequisites we should run instead of "/configure" inside of our source code directory

./contrib/download_prerequisites

This will download and untar inside the source code directory MPR, MPC and GMP
Now here is the deal, we should create a mirror-directory (just for call it something) so we get out of our source-code-directory and make a new one right next to our source code.

mkdir gcc-build

and move into our new directory

cd gcc-build

In this new directory we can run the /configure so we create a path to our source code folder and run the /configure

path/gcc-src/gcc-version/configure

this would create a "make" file in our gcc-build directory so we just run make inside the directory

make

finally we install gcc

make install

And I think that would be pretty much about it =) , this way you wont be touching the source-code-directory by building in the mirror-directory. And of course can delete that gcc-build and make another one just by following those steps.
