[MITgcm-support] MITgcm on Cygwin and MacOS X

[Ed Hill]

Hi folks,

MITgcm now runs within the Cygwin:

  http://www.cygwin.com/

environment.  This means you can use and develop MITgcm on your Windows
machines.  To do so, you should install the following packages in
addition to any defaults provided by a basic Cygwin install:

  + bash, readline, tcsh, openssh, sed, gawk, cvs, gcc-c++, 
    gcc-g77, more, vim, grep, make

The changes (mostly to genmake2) allow MITgcm to build on file systems
that have trouble distinguishing the character case.  These fixes should
make it easier to build and use MITgcm on:

  + Cygwin
  + MacOS X with the default HFS+ file system
  + Linux with a DOS FAT or HFS+ file system

though further testing is needed [can someone please lend me a MacOS X
system for a day?].

Note that Cygwin is not a preferred environment since some outstanding
problems exist.  For instance:

  1) Windows is not happy with files or directories named 
     "aux" and for that reason we suggest that you obtain 
      sources using:
       cvs co MITgcm_verif_basic

  2) The bash shell and some utilities are terribly slow on 
     Windows.

  3) Cygwin should be used in the default "Unix file 
     compatibility" mode.

These directions will appear in the user's manual shortly.
