Install terminator in CentOS 6.5 (64bit)

We installed CentOS 6.5 (64bit) using this ISO, which we downloaded from http://vault.centos.org/6.5/isos/x86_64/

Once we got the OS started, we executed yum update -y to update all installed packages that were older than the versions in the repositories.
After the update process was complete, we then tried to install terminator using yum.

Executing yum install -y terminator resulted in an error:

Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
* base: mirror.us.leaseweb.net
* extras: mirror.us.leaseweb.net
* updates: mirror.us.leaseweb.net
No package terminator available.
Error: Nothing to do

To solve the problem we needed to install the Extra Packages for Enterprise Linux (EPEL) repository using yum install -y epel-release.

After the installation was done, we executed yum install -y terminator once more and the installation of terminator succeeded.

Downgrade texinfo on CentOS 7.0 (64bit) to version 4.13

Recently we had to download texinfo from version 5.1 to any version less than version 5 series.
We used texinfo version 4.13 which is the latest in the version 4 series.

We were trying to compile some tools using an older version of gcc. Instead of using 4.8.5, we used 4.8.2 to achieve our goal and that caused a problem with some .texi files.

Methodology

#Making sure we are not missing any 32bit libraries since we are on a 64bit machine
yum install glibc.i686 ncurses-libs.i686;
#Download the source code
wget http://ftp.gnu.org/gnu/texinfo/texinfo-4.13.tar.gz;
#Extract the files
tar -zxf texinfo-4.13.tar.gz;
#Navigate to the folder
cd texinfo-4.13;
#Configure the installation and make all necessary checks
./configure;
#Build
make;
#Install
sudo make install;


Downgrade gcc on CentOS 7.0 (64bit) to version 4.8.2

Recently we had to download gcc from version 4.8.5 to 4.8.2.

We were trying to compile some tools and they required using that older version of gcc.
To compile the old version of the gcc we used the version version that was shipped with the distribution.

Methodology

#Making sure we are not missing any 32bit libraries since we are on a 64bit machine
yum install glibc.i686 ncurses-libs.i686;
#Download the source code
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.gz;
#Extract the files
tar -xvf gcc-4.8.2.tar.gz;
#Navigate to the folder
cd gcc-4.8.2/;
#Make sure we have all dependencies met
./contrib/download_prerequisites;
#Configure the installation and assign the installation folder to be /usr/local/gcc/4.8.2. Finally make all necessary checks before compilation.
./configure --prefix=/usr/local/gcc/4.8.2;
#Build
make;
#Install
sudo make install;
