I just installed Ubuntu 14.04.3, chosen because right now is the Ubuntu version that will be supported for longest time, and I'd like to install the latest version of Gmsh (version 2.10.1, July 30 2015). I could download a tgz
file (from here) but I've read that that kind of installation is not for Linux novice like me. Other ways, like PPA and deb
installation files are for older versions of Gmsh or for newer version of Ubuntu (tried that but the installation unsurprisingly fails). Should I upgrade to last non-LTS version of Ubuntu or there is a (feasible for novices) way to install Gmsh 2.10.1 in Ubuntu 14.04.3?
This question is specific about Gmsh/Ubuntu 14.04.3, but my curiosity is more general; is it possible (and how much hard is) to install latest version of a software outside of Ubuntu Software Center and without PPA and deb
installation files? (I don't pretend to install a new software on a 10 years old Ubuntu, but at least on the latest LTS version)
