[gmx-users] Are Gromacs 3.2.1 and FFTW 3.0.1 compatible?

[Joao Renato Carvalho Muniz]

Hi gromacs users!

I'm brand new user (or trying to be one) of gromacs!

Sorry about this stupid question! but I'm getting an error when I'm 
trying to compile (configure) gromacs 3.2.1:

 > configure: error: Cannot find any single precision sfftw.h or fftw.h
 > Do you have single precision FFTW installed? If you are using packages,
 > note that you also need fftw-devel to compile GROMACS. You can find the

The problem is that I've already configured and compiled fftw 3.0.1 with 
and without the --enable-float option, so I think I have both single and 
double precison!

Could anyone please tell me what I've to do?

Thank you very much for your time and consideration!

Joao Renato.
