“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.

If not for the near-20x speedup I’ve achieved running GROMACS on an nVidia GTX 770 Classified over an Intel i7 Extreme 6-core, nVidia in Ubuntu would almost be more trouble than its worth. The initial installation of the nVidia drivers from the nVidia website works, then the first time Ubuntu auto-updates the drivers to the latest-and-greatest, you’re never entirely sure what the next boot is going to look like – usually a black screen at best. And, if you found this page while looking for a solution to the nVidia driver update black/blank screen, my solution (which has worked without issue to date) is to ditch lightdm and use the GNOME Display Manager (gdm) instead (this apparently appears to be a theme with Ubuntu 14.04 installs on SSD drives as well).
sudo apt-get install gdm
Now, with that settled, the latest update (331.113) broke my GROMACS GPU install (performed using the steps outlined at: GROMACS 5.0.1, nVidia CUDA Toolkit, And FFTW3 Under Ubuntu 14.04 LTS (64-bit); The Virtues Of VirtualBox). The error for my system looks as follows:

Summarized below are the catches and fixes from a recent effort to build GROMACS 5.0.1 with FFTW3 (single- and double-precision) and GPU support (so, single-precision). Also, a trick I’ve been doing with great success lately, using a virtual machine to keep my real machine as clean as possible.
0. The Virtues Of VirtualBox
Open source means never having to say you’re sorry.
I’ve made the above proclamation to anyone who’d listen lately who has any interest in using Linux software (because, regardless of what anyone says on the matter, it ain’t there yet as an operating system for general scientific users with general computing know-how). You will very likely find yourself stuck at a configure or make step in one or more prerequisite codes to some final build you’re trying to do, leaving yourself to google error messages to try to come up with some kind of solution. Invariably, you’ll try something that seems to work, only to find it doesn’t, potentially leaving a trail of orphaned files, version-breaking changes, and random downgrading only to find something else stupid (or not) fixed your build problems.

Author’s Note 1: It is my standard policy to put too much info into guides so that those who are searching for specific problems they come across will find the offending text in their searches. With luck, your “build error” search sent you here.
Author’s Note 2: It’s not as bad as it looks (I’ve included lots of output and error messages for easy searching)!
Author’s Note 3: I won’t be much help for you in diagnosing your errors, but am happy to tweak the text below if something is unclear.
Conventions: I include both the commands you type in your Terminal and some of the output from these commands, the output being where most of the errors appear that I work on in the discussion.
Input is formatted as below:

I’ll qualify this post by saying that (1) I have given up on Ubuntu 11.x and 12.x because they are consistently unstable on my hardware (so, if you have issues running this installation on those versions, I may not be of much help (although I suspect things should work)), (2) I am starting this install from a fresh 32-bit Desktop Ubuntu 10.04 install (so do not know if there are any issues with other software one might have installed on a Linux box if a problem comes up), and (3) the procedure comes out of the current lack of an Ubuntu binary currently listed as available (as of 6 April 2013) from the LAMMPS website (lammps.sandia.gov/download.html#ubuntu). If (3) changes and is available in an MPI form, what’s below will hopefully be unnecessary.
Building Trouble And Solutions
My initial “just unzip, untar, and make linux” attempt on a fresh 10.04 install produced the following error (which I’m reproducing in the expectation that you found this page by typing one of the errors below into a search engine, so you’ll find the error and the solutions). NOTE: I build all my programs in /opt for organizational purposes (so replace accordingly):

This post is a brief update to a much longer and more involved discussion of Amber 11 and AmberTools installation in Ubuntu 10.04 LTS (Lucid Lynx) (as the changes are minor and the parallelization setup remains largely the same). You can find this more involved discussion at www.somewhereville.com/?p=1422.
Long/Short – the installation under Ubuntu 12.04 LTS (Precise Pangolin) is not much different and goes without hitch provided you keep your locations organized. NOTE 1: I’ve not a copy of Amber12, so cannot speak for any changes to its installation procedure. NOTE 2: This install assumes 32-bit only.
If you tried installing all of the build software from the 10.04 LTS post, you’ll receive errors like the following (as usual, I include error messages for those who are searching against error messages)…

It has been a banner week for Ubuntu installations.
The installation of Abinit 5.6.5 with OpenMPI 1.3.1 (previously reported at www.somewhereville.com/?p=384) wasn’t bad, but several games had to be played (at the time) to make everything compile and run correctly. I’m pleased to report that Abinit 6.8.1 and OpenMPI 1.4.1 seem to play better together, this simplified considerably over the previous installation guide by the use of the apt-get version of OpenMPI 1.4.1. A bit of option calling in the configure step is needed (and the errors for not doing it are included below).

Having successfully navigated serial and parallel Amber10 installs under Ubuntu 8.10, I am pleased to report that the process for Amber11 with OpenMPI (from apt-get, one doesn’t have to build from scratch) under Ubuntu 10.10 is seemingly much easier (and have it here so I don’t forget). There is a bit of persnicketiness to the order of the serial and parallel installs that must be kept track of (and I’m building in serial-to-parallel order), but the process is otherwise straightforward.
For organizational purposes, I’m building amber11 in my $HOME directory. This removes some of the PATH issues with sudo-ing aspects of the install (and can be moved into another directory after the build is complete).
1. apt-get Installs
The search for dependent programs and libraries is a long and involved one given how many programs I have installed. Therefore, instead of trying to find all of the amber-dependent installs for successful building, I’m simply providing the list of everything I have on the test machine. As hard drives are cheap and Ubuntu will warn of conflicts, I recommend simply installing the below and accepting the 100 Mb hit to NOT have to find the smallest apt-get set (yes, some of these are obviously not needed).

Taking care of a DNA/RNA fragment alignment installation triple-threat with this post. These Ubuntu installs for largely problem-free, but one little trick is needed for Amos (this because of my use of “/opt” for my usual installation and compilation attempts and, more so, my not being interested in modifying the root PATH statement despite the constant use of sudo when building in “/opt”).
So, with the downloads of
bfast-0.6.5a (currently: sourceforge.net/apps/mediawiki/bfast/index.php?title=Main_Page)
MUMmer-3.22 (currently: mummer.sourceforge.net)
Amos-3.0.0 (currently: sourceforge.net/apps/mediawiki/amos/index.php?title=AMOS)
taken care of, the following process is performed.

And happy new year.
I had thought this was something involving Gaussian09 memory usage until I restarted a machine and found the same problem occurring in Ubuntu. Below is a quick fix (and reminder for the future).
