make - "No such file or directory" -OR- VirtualBox Additions won't install

Issue:
Clean install of Ubuntu. When you try to “make” something, you get errors like these:

error: stdlib.h: No such file or directory
error: stdio.h: No such file or directory
error: string.h: No such file or directory

etc…

Cause:
Basic CD install does not install all of the dev tools.

Fix:
Run this command:

sudo apt-get -y install build-essential

 

This also is required when installing the VirtualBox Additions.
