Re: Storm trak problems

Hi Carl,

I think this example needs to be updated, because it shouldn't need
the *.so file anymore, and hence you don't need to run WRAPIT.

Try editing this example, and changing the lines:

load "wrf_user_mass.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"

to:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"

The functions from "wrf_user_mass.ncl" are now in the
"WRF_UserARW.ncl" file, which is included with the 5.0.0
distribution. This file doesn't have any shared object dependencies.

I'll fix the example on the web.
