[gmx-users] gromacs-4.6.tar.gz installation question

[jeela keel]

*Dear All,

I am trying to install gromacs, I dowloaded
**gromacs-4.6.tar.gz<ftp://ftp.gromacs.org/pub/gromacs/gromacs-4.6.tar.gz>and
following the instruction in the following website
http://www.gromacs.org/Documentation/Installation_Instructions#4._Doing_a_build_of_GROMACS

I read the instraction but I am still kind of confused. Do I need to
download both FFTW and CMake or just choose one of them for the gromacs
installation?
Also can I use FTTW
**fftw-2.1.5.tar.gz<ftp://ftp.fftw.org/pub/fftw/fftw-2.1.5.tar.gz>instead
of
**fftw-3.3.3.tar.gz <ftp://ftp.fftw.org/pub/fftw/fftw-3.3.3.tar.gz> becuase
I also want to download Lammps in my computer that can only use fftw 2.1.5

Thank you fro your help

Jeela
