I am trying to install catalyst drivers by Radeon and I fail because /lib/modules/3.13.0-45-generic/build/include/linux/version.h
is missing. I tried following similar questions to find that I need to install the headers and I did. Without managing to generate the required file. Below is the list of installations I did to make this work. I am running Ubuntu 14.04
sudo apt-get install linux-generic
sudo apt-get install gcc
sudo apt-get install lib32gcc1
sudo apt-get install dkms gcc build-essential linux-source linux-headers-`uname -r`
