Re: ESMF_RegridWeightGen not found

Hi Sean,

As we discussed offline, if you downloaded the =
"ncl_ncarg-6.1.2.MacOS_10.6_64bit_gcc460.tar.gz" binary from the =
www.earthsystemgrid.org website, then you should have =
"ESMF_RegridWeightGen" already.

If you are not seeing this file:

  ls $NCARG_ROOT/bin/ESMF_RegridWeightGen

then one of the three things might be the reason:

  1. NCARG_ROOT is not set to the correct parent directory
  
  2. NCL was not installed from the =
"ncl_ncarg-6.1.2.MacOS_10.6_64bit_gcc460.tar.gz" tar file, but rather =
from source code. ESMF_RegridWeightGen is not part of our software =
stack and has to be built separately.

  3. The special (and not widely known) "ESMFBINDIR" environment =
variable is set, but doesn't contain this executable.

In any case, I have provided the "ESMF_RegridWeightGen" binary for MacOS =
10.6 on our ftp:

    ftp ftp.ucar.edu
    <log in as "anonymous">
    <Use email address as password>
    cd /pub/scd/haley
    get ESMF_RegridWeightGen
    quit
