If you did a recent install using fink, it has the option set to separately compile the fortran library from the C library, so your compile line would need something like -L/sw/lib -lnetcdf -L/sw/lib/netcdf-gfortran/ -lnetcdff However, if it is from a recent install, I wouldn't be surprised if g77 fails and you would need to use gfortran instead. But give it a try. -Roy On Jul 29, 2010, at 1:13 PM, Jose Borrero wrote: > > Hello everyone, > > I am sure this an incredibly basic question, but maybe someone can tell me > what i am doing wrong.
