amdgpu-pro 17.30 non conventional PKGBUILD

# Inspired from the original work of Janusz Lewandowski <lew21@xtreeme.org>
# and David McFarland <corngood@gmail.com>
# from https://aur.archlinux.org/pkgbase/amdgpu-pro-installer
# Modified : nmset@netcourrier.com
# Thanks to Paullux (https://aur.archlinux.org/account/Paullux)
# for testing the 32-bit setup and sanitizing the 'provides' instructions.

#Alien PKGBUILD, not for general use.
#Download amdgpu-pro-17.30.465504.tar.xz separately (.deb) and makepkg.
#Reboot after install, libraries are not in standard locations.
#If X fails to start,
#log through SSH
#OR reboot (wildly or with magic SysRq) on another partition and chroot in some way to your partition
#To uninstall in any case:
#Close DE; in a TTY :
#pacman -Rdd amdgpu-pro
#pacman -S xf86-video-amdgpu ocl-icd lib32-ocl-icd
#Reboot
