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

  * '''Cygwin setup for gfortran'''

  In order for gfortran to work properly on [wiki:Cygwin Cygwin] make sure you have math packages [http://cran.r-project.org/doc/packages/gmp.pdf GMP] and [http://www.mpfr.org/ MPFR] installed on your machine.
  
  Open a Cygwin shell and type ''cygcheck -c | grep gmp'' as well as ''cygcheck -c | grep mpfr'' to confirm you have GMP and MPFR packages.
