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.
I've an install I'm quite happy with that has all of the working code I want on it working – and I've no interest in having to perform re-installs to get back to a working state again.
My solution, which I've used to great success with GAMESS-US, GROMACS, NWChem, and Amber (so far), is to break a virtual instance in VirtualBox first. For those who don't know (and briefly), VirtualBox lets you install a fully-working OS inside of your own OS that simply sits as a file in a Virtual VM folder in your user directory. My procedure has been to install a 60 GB VirtualBox instance of (currently) Ubuntu 14.04 (which I will refer to here as PROTOTYPE), fully update it to the current state of my RealBox (updates, upgrades, program installs, etc.), then copy PROTOTYPE somewhere else on the machine. The only limitation of this approach is that VirtualBox doesn't give you access to the GPU if you're testing CUDA-specific calculations. That said, it does let you install the CUDA Development Toolkit and compile code just fine, so you can at least work your way through a full build to make sure you don't run into problems.
When you're done trashing your VirtualBox after a particularly heinous build, just delete PROTOTYPE from Virtual VM and re-copy your copy back into Virtual VM – voila! You're ready for another build operation (or to make sure your "final" build actually works flawlessly before committing the build to your RealBox.
That's all I have to say on the matter. Consider it as your default procedure (at this point, I won't touch my RealBox with new installs until I know it's safe in VirtualBox).
1. The State Of My Machine Pre-GROMACS And All Other apt-get's Used Below
What follows below is pretty straightforward. Errors you might get that don't appear below might be related to the lack of certain installs on your machine that I installed on VirtualBox. That is, my standard PROTOTYPE comes standard with Intel's Fortran and C Compilers (for code optimization). Those installs required a few installs above the base Ubuntu install. These are (and are pretty standard anyway, so I say install them anyway):
sudo apt-get install build-essential gcc-multilib rpm openjdk-7-jre-headless
I could have just installed a fresh version of 14.04 onto a machine to try this myself, but I'm not that motivated. Also, note this list does not include the all-important cmake. We'll get to that.
And for the rest of GROMACS (at least for older versions), there were lots of mesa/gnuplot/motif-specific dependencies in older versions of GROMACS to build all of the files included in the GROMACS package. Regardless of GPU builds or not, I tend to default to install all the packages below just to have them (which all, for 14.04, currently apt-get properly).
sudo apt-get install openmpi-bin openmpi-common gfortran csh grace menu x11proto-print-dev motif-clients freeglut3-dev libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev libgl1-mesa-dri libcurl-ocaml-dev libcurl4-gnutls-dev gnuplot
If you don't install the libblas3gf libblas-doc libblas-dev liblapack3gf liblapack-doc liblapack-dev series, you'll see the following note from your cmake steps in GROMACS.
— A library with BLAS API not found. Please specify library location.
— Using GROMACS built-in BLAS.
— LAPACK requires BLAS
— A library with LAPACK API not found. Please specify library location.
— Using GROMACS built-in LAPACK.
My own preference is to use the (assumedly newer) Ubuntu-specific libraries from apt-get.
sudo apt-get install libblas3gf libblas-doc libblas-dev liblapack3gf liblapack-doc liblapack-dev
GPU-Specific? One More apt-get
My first passes at proper GPU compilation involved several steps for the nVidia Developer Toolkit install. That's now taken care of with apt-get, so perform the final apt-get to complete the component/dependency installations.
sudo apt-get install nvidia-cuda-dev nvidia-cuda-toolkit
With luck, your first attempt at a GPU-based installation will look like the following:
[0%] Building NVCC (Device) object src/gromacs/gmxlib/cuda_tools/CMakeFiles/cuda_tools.dir//./cuda_tools_generated_copyrite_gpu.cu.o

3. First Pass At GROMACS
The make install step will place GROMACS where you want it on your machine, so you're just as good building in $HOME/Downloads as you are anywhere else. I will be performing all operations from $HOME/Downloads unless otherwise stated.
According to the GROMACS Installation Manual, your quick-and-dirty install need only involve the following:
$ tar xvfz gromacs-src.tar.gz
$ ls
gromacs-src
$ mkdir build
$ cd build
$ cmake ../gromacs-src
$ make
This allows you build "out-of-source" as they put it. Frankly, I just dive right into the GROMACS folder and have at it.
CMake Error: The source directory "/home/user/Downloads/gromacs-5.0.1/build" does not appear to contain CMakeLists.txt.
Specify –help for usage, or press the help button on the CMake GUI.
And did you see the above error? If so, you read the GROMACS quick-and-dirty procedure backwards. I'm not running it this way, so doesn't matter to what follows.
My first attempt at building GROMACS produced the following output from PROTOTYPE (reproducing all the text below).
user@PROTOTYPE:~$ cd Downloads/
user@PROTOTYPE:~/Downloads$ gunzip gromacs-5.0.1.tar.gz
user@PROTOTYPE:~/Downloads$ tar xvf gromacs-5.0.1.tar

user@PROTOTYPE:~/Downloads$ cd gromacs-5.0.1/
user@PROTOTYPE:~/Downloads/gromacs-5.0.1$ cmake -DGMX_GPU=OFF
NOTE: If you just run cmake, you'll get the following…
cmake version 2.8.12.2
Usage
cmake [options]
cmake [options]
…
… which is to say, cmake requires at least one option be specified. Above, I'm just using -DGMX_GPU=OFF to start the process.

Lots of little things to address here. We'll get to the Boost problem later. Meantime, you can see the critical error is in (1) the lack of FFTW3 and (2) the lack of my specifically asking for -DGMX_BUILD_OWN_FFTW=ON in the cmake process.
NOTE: If you try to fix the FFTW3 problem as described above, you'll get the following error:
-GMX_BUILD_OWN_FFTW=ON
CMake Error: Could not create named generator MX_BUILD_OWN_FFTW=ON
Make sure to put the "D" in:
-DGMX_BUILD_OWN_FFTW=ON
4. If You Don't Use DGMX_BUILD_OWN_FFTW=ON To Build FFTW3…
This is a skip-able section if you're letting cmake do the dirty work (and letting cmake do it is preferred, at least for getting GROMACS built). In trying sudo apt-get install fftw*, you see (currently) the following: fftw2 fftw-dev fftw-docs
No good. So, the procedure is to build FFTW3 from source (which is just as easy as installing from .deb or .rpm files if you installed everything I mentioned above). That said, your attempts to build FFTW3 and build GROMACS may have run into several errors because of how you built FFTW3. Beginning with your extracting and prep for make:
user@PROTOTYPE:~/Downloads$ tar xvf fftw-3.3.4.tar

Sadly, the solution is to then include -DGMX_EXTERNAL_BOOST=off and stick with the internal boost, which then "makes" just fine. One page references the use of -DGMX_INTERNAL_BOOST=on, but that produced the following:

There's more on this issue at: gerrit.gromacs.org/#/c/1232/ and t24960.science-biology-gromacs-development.biotalk.us/compiling-boost-problem-and-error-with-icc-t24960.html, but I've opted not to worry about it.
So, with Boost installed, I simply ignore it (and have not installed Boost on my RealBox).
user@PROTOTYPE:~/Downloads/gromacs-5.0.1$ cmake -DGMX_GPU=ON -DGMX_EXTERNAL_BOOST=off
6. Finishing Step If All Above Goes Well: CUDA-Based GROMACS Build
If everything else above has gone smoothly (and if you ignored the Boost install. If you didn't, remember to add -DGMX_EXTERNAL_BOOST=off to the cmake below), you should be able to cleanly run a cmake for a GPU version of GROMACS (below, with the final result to be placed into /opt/gromacs_gpu. You then specify the $PATH after and run with it).
user@PROTOTYPE:~/Downloads/gromacs-5.0.1$ cmake -DGMX_GPU=ON -DCMAKE_INSTALL_PREFIX=/opt/gromacs_gpu -DGMX_BUILD_OWN_FFTW=ON
