Note: 
While compiling you may get one error like: "c++: internal compiler error: Killed (program cc1plus)" the reasons of this can be:

Low ram/swap amount: increase ram/swap to a minimum of 2GB of ram and 2GB of swap or decrease the amount of make -j to 1. (you can get this using VPS servers)
Selinux kernel: change to one non-Selinux kernel or use Debian 9 or Ubuntu 16 compiling with clang or compile without pch. (you can get this issue when using OVH hosting).
