If you are on Ubuntu, you should just use the PPA. While other distros will probably different ways to get the daily builds (Google is a friend). However getting Flash to work would probably be the same across the board.
If you never added software from a PPA, here is what you should do to get Chromium:
Add these two lines to your /etc/apt/sources.list:
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main deb-src http://ppa.launchpad.net/chromium-daily/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main
You may want to add the corresponding GPG key to your apt keyring.
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 4E5E17B5
sudo apt-get update
sudo apt-get install chromium-browser
Now to get Flash running, we basically need to create a symbolic link of libflashplayer.so in the Chromium plugin folder:
cd /usr/lib/chromium-browser/plugin sudo ln -s ../../flashplugin-installer/libflashplayer.so
One final step is to change the execution command to your Chromium icon to this (Note these flags have two “-“, for some reason WordPress is rendering only one):
chromium-browser --enable-plugins --enable-greasemonkey --enable-user-scripts --enable-extensions
Thats it! If you face any problems, just leave a comment or @rtaibah on Twitter!
Update: Chromium also integerates very well with GNOME, just go to options menu > Personal Stuff > Set To GTK Theme OR even get more themes
