Build ROMS using gfortran on Win32 Machine

Below is the step by step procedure for a successful compilation of ROMS3.0 on a win32 machine under Cygwin.

• Cygwin setup for gfortran

In order for gfortran to work properly on Cygwin make sure you have math packages ​GMP and ​MPFR installed on your machine. Open a Cygwin shell and type the following commands to confirm you have GMP and MPFR packages.

$ cygcheck -c | grep gmp (If you see what is shown below then you're ok)

gmp 4.2.1-1 OK

libgmp3 4.2.1-1 OK

$ cygcheck -c | grep mpfr (If you see what is shown below then you're ok)

libmpfr1 2.2.1-1 OK

mpfr 2.2.1-1 OK

If cygcheck fails to report the GMP and MPFR package installations, then install these packages using Cygwin Setup. These packages are found under 'Libs' category in package installation list of cygwin setup.
