If you want to use binary packages I highly recommend to use the PPA here in order to get the newest version:
https://launchpad.net/~ginggs/+archive/ubuntu/deal.ii-backports After that make sure that you actually install the developer version. All in one: sudo add-apt-repository ppa:ginggs/deal.ii-backports sudo apt-get update sudo apt-get install libdeal.ii-dev After that, a simple $ cmake . should be enough to configure the example steps.
