"Think" is very different from "know," hence why the questions about your
success and failure were warranted. From your earlier post, it was quite clear
that you had only installed a single-precision version of fftw, but then you
chose to install single-precision Gromacs in /opt/fftw, and then a
double-precision version in /opt/gmx.
Hence the confusion as to what you had actually done. In the future, it is more
efficient (and makes you seem more capable) if you directly copy and paste from
your terminal the exact commands you used.

No, but if you're installing double-precision Gromacs, you'd better make sure
you've installed double-precision FFTW, which, from your earlier post, you haven't.
