This approach uses update-alternatives to manage GCC and LLVM/CLANG C/C++ compiler toolchains. Although tested on Linux Mint 18.3, this approach should work on any Debian based distro or for that matter any Linux distro with update-alternatives support, provided the packages are installed correctly.

There are 3 files

• gcc-alternatives.sh installs GCC versions 5/6/7 and sets up alternatives for gcc/g++/cpp/gfortran.
• llvm-clang-alternatives.sh installs LLVM and CLANG versions 4/5 and sets up alternatives for various LLVM and CLANG programs including clang and clang++.
• cc-alternatives.sh sets up alternatives for the cc, cxx, and the ld commands. This script can be used to change systemwide default compiler/linker combination to either GCC or CLANG.

Once these scripts are run you can change the system GCC/CLANG versions by running sudo update-alternatives --config gcc|clang. To change the default compiler/linker combo used by t

Setup a Headless Virtual Machine on Windows using Oracle VirtualBox

If you are concerned with having many windows open when running several virtual machines on your Windows server or workstation, then have them run headless using VirtualBox commandline tools. Additionally, you can manage these VM's using RDP (Mircrosoft Terminal Server Connection - mstsc.exe) or SSH access (if enabled)

Install VirtualBox and Extension Packs

• Download the latest version and install of [Oracle VirtualBox] [vbox]
• Download the [VirtualBox Extension Pack] [vbox] and install for the same version
