HelloI have been attempting to compile and build Gromacs 5.0.4for a couple of
weeks. I have been following the instructions (having also readGromacs 5.0
instruction in Manual..) at
https://ourphysics.org/wiki/index.php/How_to_compile_Gromacs#Gromacs_5.1.1_MPI.2C_single
Specifically, I have used “Gromacs 5.0.4 MPI, Single, GPU”instructions at
this site; however, without the “GPU” part.. I have both OpenMPI and
FFTW-3.2.2 in the standardlocations. In the screen output when I use CMake to
compile, I get the message that “can’t locate fftw3fmodule” . However, the
configurations is done and the build files are made;however, I also get the
message “CMake warning that manually-specified variableswere not use by the
project: GMX_BUILD_FFTW” Does this mean FFTW is disabled? Not sure.. I
made sure that I was using the correct version of CMakewhich is CMake-3.5.2
and the correct FFTW-3.2.2,,, I did find on line where someone online said if
they reconfiguredFFTW with "--enable-float" that theysolved the problem of
“can’tlocate fftw3f module”; but this was for Gromacs 4.5 and there is no
realexplanation. So, I am hesitant to try this….. Any information would be
extremely helpful!!! Thanks Steve
Please make sure your emails have sensible line breaks; this is very hard to
read.
What you're observing is that "GMX_BUILD_FFTW" is not a valid argument. It's
"GMX_BUILD_OWN_FFTW" and that's only needed if you want GROMACS to build FFTW
for you. Since you already built FFTW (although 3.2.2 is utterly ancient, so
you should get the latest version, i.e. 3.3.5) then you don't need this option.
This is confirmed by the fact that, as you say, configuration completes. If
cmake can't find a suitable FFTW, it will throw a fatal error.
