g2ctl and windows

[Burn James]

Hi Arlindo

The main version of Grads we have here is 2.0.a3.oga.1

We also have access to the Cygwin version of Grads 2.0.a5.oga.4 - some of
our scripts are using this version now. It was from this version that I
took the latest version of wgrib2.  The g2ctl I used is an .exe file -so
perl not needed?

Okay, trying with a g2ctl.pl and a perl v 5.6.0 for MSWin - from 2002 by
the looks - getting some error message: can't locate POSIX.pm in @INC (@INC
contains: .)  BEGIN Failed - compliation aborted at line 36...  I'll have a
play with the perl options here - Not sure about how to get a different
(Cygwin?) version.

BTW I love what you're doing with the other extensions stuff with Grads - I
run OpenSuse at home and am trying to pluck up courage and get into the
PyGrads or Perl interface...

Cheers
James
