Hi John,

You do not have g77 installed on your system. I assume you have a newer
operating system in which the default gcc is 4.3. g77 was scrapped
starting with this version of gcc. But you can use gfortran (the default
fortran compiler of gcc 4.3) to compile amber tools 1.2. it worked fine
for me...

Which OS do you have? If you have Debian or an rpm based Linux system
gfortran needs to be installed separately from gcc ...Usually the
configure script looks for gfrotran after not finding g77. In your case
it doesn't do so. Its probable that you also don't have gfortran installed.

of course you can also install an older version of gcc and use its g77
if you want to .... But as I said it worked for me with gfortran ...

Cheers
vlad
