@jdhao thank you for posting this...it was very helpful! Now I need to downgrade back to gcc 4.8, but I am unable to. Any advice on how to do so?
@miamartin8, I think you can just install gcc 4.8. Multitiple gcc installation is fine, you can just add --prefix /gcc/install/path to indicate where you want to install it instead of the default location. After installation, you can manipulate your $PATH variable to indicate which gcc you want to use.

too dependent on yum can be problematic since it requires sudo.
@knasim, yeah, that is true. If you do not have sudo rights, you also have to compile the dependencies from source.
At the time of writing this script, I had sudo rights, so I just installed the dependency via yum.
@jdhao
do I need to add this in my profile?
export PATH=/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
or optional?
In my case, this script is giving error:
I solved this by installing gcc-c++
