I HAVE installed FFTW, but the configuration script still says it can't find it! |

OK. The problem is most probably that your compiler doesn't look for the header files and/or libraries in the place where you installed them. It's easy to fix; you can just tell the GROMACS configure script to add those directories to the search paths. Specify the header file directory (e.g. /home/erik/fftw/include) as
| CPPFLAGS="-I/home/erik/fftw/include" | |
and the location of the libraries (e.g. /home/erik/fftw/lib) in
| LDFLAGS="-L/home/erik/fftw/lib" | |
and then run the GROMACS configuration script. Note that some compilers don't search /usr/local by default, so you might have to specify these paths even if you installed FFTW in the default place.
