Setting up the Deep Learning Env
Step 1 : Assemble the PC
Step 2 : Create an bootable Ubuntu 18.04 LTS flash drive
install CUDA 9.1 on Ubuntu 18.04 using the .run file & gcc version 6 & g++ version 6

First erased the current update-alternatives setup for gcc and g++:
sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
Install Packages
It seems that both gcc-4.3 and gcc-4.4 are installed after install build-essential. However, we can explicitly install the following packages:
sudo apt-get install gcc-4.3 gcc-4.4 g++-4.3 g++-4.4
Install Alternatives
Symbolic links cc and c++ are installed by default. We will install symbol links for gcc and g++, then link cc and c++ to gcc and g++ respectively.
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.3 10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 20
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.3 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.4 20
sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30
sudo update-alternatives --set cc /usr/bin/gcc
sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30
sudo update-alternatives --set c++ /usr/bin/g++
