"Stop that!" – George Carlin
If you've obtained source code from an academic lab that was last developed some time ago and you spent a whole day installing libraries and symbolic links and redefining variables in your .bashrc and downgrading libraries and redefining paths and have 20 tabs open in your browser that all go to 20 different obscure error discussions on Stack Overflow and it's late and you're tired and you think you might not need the program after all if you do a bunch of other workaround things instead – what's below is for you.
Academics have been developing small code for (nearly) millions of years to make their lives easier – and we all benefit when that code is made available to others (esp. when it helps in data analysis). When that code is a series of perl or python scripts, there's generally little reason why you should have any run issues. When they call on external libraries or specific tools, generally that information is available in the README somewhere. Generally speaking, there's no reason why a code shouldn't work in a straightforward manner when the developer doesn't make it known that something else needs be installed to make it work.
So, why doesn't code A work on your linux box? A few possibilities.
0. You didn't read the README right.
1. The developer skipped some documentation and you're missing a library or program that they installed months earlier but forgot about (and they forgot to acknowledge that that was a needed item to run their program).
2. Your linux distro is too new, they developed it on something much older, have never updated their own machine, and something fundamental changed between, for instance, Ubuntu 8.04 and 14.04 (I've run into a few in that category – depending on the code, this can sometimes just be chalked up to a compiler difference issue that went unnoticed by the developers).
3. The one you learn the harder way – Ubuntu is not Fedora is not OpenSuse is not [insert distro here]. Half of the Ubuntu posts on this website stem from my having needed to do something under Ubuntu to make it look a little tiny bit more like whatever distro a developer developed their code with.
Let's hammer on point 3 for a minute – I know precious few academics who use computers as part of research who are both (1) experts in coding and (2) experts in interpreting the output of some code. A properly working code in the hands of a productive researcher can mean the difference between an OK interpretation of data and a very descriptive interpretation of data that anyone else could follow (which, let's not lie to ourselves, may also mean the difference between a journal with an impact factor of 0.5 and one of 5.0). Disregarding any "it was hard to code, it should be hard to use" mentality, finding out that a program runs painlessly on distro A with NO effort after trying in vain on distro B with CONSIDERABLE effort is a rather important piece of information.
For the record – this isn't about a user's ability to program, install, admin their machine, etc. It's simply about ease-of-use for ALL users regardless of their computational aptitude (which is why many of the Ubuntu posts on this website are exhaustive in their reporting of errors as well as work-arounds).
Which brings me to one of the most versatile (and storage-consuming) programs on my Ubuntu 14.04 machine – VirtualBox. VirtualBox (and related) are absolutely awesome for their abilities to let you try – very quickly – the quick fix that is the building or running of a strange code "somewhere else." For the record, I ALWAYS try something new using a clean Ubuntu 14.04 image under VirtualBox before I ever let it touch my main machine – and that's because I've had more than one instance in the past of trying to build a piece of software that then destroyed (well, sort of) my machine. When you destroy an image with a bad installation attempt – all you have to do is trash the image and copy a fresh one over from some "clean image" folder. Could not be easier. Furthermore, I've still ONE app that works in Windows XP that doesn't work anywhere else. And I've two or three under Windows that I use generally – all ready for use under VirtualBox without having to reboot anything.
Additionally importantly – Virtual Machines allow you to "sample in time" – working around new & improved features and functionality in new compilers and libraries by instead building code on what was available at the time of the code's release.
Anisotropy of the Current (Induced) Density – ACID
From the website of Prof. Dr. Rainer Herges
The "density of delocalized electrons" is a concept that is intuitively used to explain the electronic structure of conjugated systems. Unfortunately, however, there is no rigorous way to separate the total electron density in a density of localized and delocalized electrons. Like aromaticity, bond order, point charge, and other important concepts of chemistry, a definition for the density of delocalized electrons has to be derived from more fundamental quantum theoretical parameters.
As observables, magnetic properties are a suitable starting point for a general description of of delocalization and conjugation. In analogy to the anisotropy of the magnetic susceptibility, which is a powerful measure of aromaticity, we investigate the anisotropy of the current (induced) density (ACID). Similar to the square of the wavefunction which defines the total electron density, the ACID scalar field defines the density of delocalized electrons.
The ACID method proved to be an extremely versatile and descriptive tool to analyze delocalization in ground-state molecules, excited states, transition states, organometallics, hyperconjugation and other through-bond and through-space interactions.
Having spent quite some time determining the best way to account for electron delocalization in an upcoming project, the ACID method ("Delocalization of Electrons in Molecules," J. Phys. Chem. A 2001, 105, 3214-3220. dx.doi.org/10.1021/jp0034426) struck me as near-ideal, leading to my request for the code from the developers.
With the code graciously provided, my first run attempt under Ubuntu 14.04 (and Cygwin, and Ubuntu 10.04 because it was waaaaay back when) went less-than successfully after the successful Gaussian run.

Not a particularly Ubuntu-looking problem, and not one for which anything online was available that helped at all. The .pov file is written, but the file is empty. Googling the error above…
/opt/AICD-2.0.0/AICD: line 656: 17519 Aborted … (core dumped) $Animation $inputbasename.pdb
… sends you to, among other pages, one Stack Overflow discussion that starts with the error and ends with recommendations of finding a good debugger – not something I'd any interest in pursuing as part of getting this code to work.
I did not find any version-dependence discussion with the errors above, but opted to try using an older gcc – that I wasn't about to install on my new Ubuntu box. Ergo, find an older distro that installs an older gcc. I threw it on an OpenSUSE 11.2 image because the developer group is in Germany – that's basically why – and because I couldn't find an old enough Ubuntu distro that would update/upgrade/install apps from the current repositories.
OpenSUSE 11.2 make Results (Note: Using gcc 4.5)
From a fresh OpenSUSE 11.2 install, I added the appropriate developer tools to get the ACID code made (note the specific request for gcc 4.5):
sudo zypper install autoconf automake binutils-gold gcc gcc45 glibc-devel kernel-desktop-devel kernel-devel kernel-source linux-glibc-devel m4 make gcc-c++
Then added povray (and nano, but that's because I hate vi)
sudo zypper install povray nano
The build process then goes as follows – with no issues.

Producing the beautiful and informative image shown above (despite the Parse Warning and Possible Parse Errors above).
For the record, compiler version differences can be subtle beasts – and my whole discussion above is not directly related to getting ACID to work. The above is a mix of brute force and resource consumption that provided a much faster turnaround in positive results than any amount of work spent in Ubuntu itself to make ACID run successfully – and does not require modifying anyone's code (an added bonus for those who might have to ask questions of the developers).
So, I would posit that the issue turns out to be a 4.5 vs. 4.8 thing, but I've not explored the issue further (frankly, no time – and it's working – so I don't know at what point in gcc development that the make process began to produce errors in the ACID code). This isn't technically the way to run it natively in Ubuntu, but is a way to get it to run in Ubuntu, which still counts in my book. In theory, a VirtualBox install and some book work on finding the dates of certain distros provides yet another way of getting stuff to just work.
That said, getting OpenSUSE to play with the Networking in VirtualBox appears to be a real pain. My solution for that for getting files back-and-forth to process?
