[ncl-install] Error while using pre-compiled NCL binaries

[Mary Haley]

Sagar,

If you want to remove this restriction, you need to do two things. Assuming
$NCARG represents the top level directory of the NCL source code:

1) Edit the file $NCARG/ni/src/lib/nfpfort/wrf_write_wps.f and change this
line:

      character(len=9)  FIELD

to whatever length you want.

2) Edit the file $NCARG/ni/src/lib/nfp/wrfwpsW.c and change this line:

  int FIELD_LEN=9;
to match the same length that you used in the Fortran file.

You then need to rebuild NCL, which is not trivial, unless you've already
got a build of NCL working.  If you already have a build that you haven't
done a "make clean" on, then you can update your NCL simply by typing:

cd $NCARG/ni/src
make all install

I don't know if making a change like this to the WPS intermediate file is
going to be a problem. Again, wrfhelp is CC'ed here in case they have
anything to add.
