If you choose Chromium…
It’s easy to install Chromium, the most powerful browser from Google, in Arch Linux. Just make sure you have enabled “extra” repository in /etc/pacman.conf and type:
$ pacman -S chromium
all things done.
If you’d like to install Google Chrome Stable…
However, if you’d like it more stable, you can take a look in AUR. Of course it’s not provided by Arch Linux officially. The package I use is here:
google-chrome 16.0.912.75-1 by t3ddy
https://aur.archlinux.org/packages.php?ID=37469
Download the tarbell and untar it:
$ tar xzf google-chrome.tar.gz
$ cd google-chrome/
And then make package:
$ makepkg -s
You may see the makepkg script asking you to download required libraries. Confirm and continue. After running makepkg script, the current directory (google-chrome/) contains a few extra files, include “google-chrome-xx.x.xxx.xx-x-YOUR_ARCH.pkg.tar.xz”. Install it by pacman, for example in my case:
$ pacman -U google-chrome-16.0.912.75-1-x86_64.pkg.tar.xz
Confirm and install. Now you should see Google Chrome in gnome-shell (kde kickoff or something.)
