[gmx-users] compiling gromacs 3.1.3 on MacOSX

[Valentin Gogonea]

Rams,

I reformat the disk, reinstalled OSX and fink and than installed g77 and 
fftw with fink. So when I tried to install gromacs

./configure --disable-float  --disable-altivec-ppc

I got the following error:

configure: error: Cannot find any double precision dfftw.h or fftw.h
Do you have double precision FFTW installed? If you are using packages,
note that you also need fftw-devel to compile GROMACS. You can find the
software at www.fftw.org, and detailed instructions at www.gromacs.org.

Did you compiled fftw yourself?

If I try to compile myself it finds that g77 is not working. Do you have 
any suggestions?

Valentin
