[ncl-talk] Problem with ESMF_RegridWeightGen

Felix,

FYI: you don't need to set all of these:

NCARG_FONTCAPS=/home/felix.carrasco/NCL/lib/ncarg/fontcaps
NCARG_GRAPHCAPS=/home/felix.carrasco/NCL/lib/ncarg/graphcaps
NCARG_DATABASE=/home/felix.carrasco/NCL/lib/ncarg/database
NCARG_LIB=/home/felix.carrasco/NCL/lib/ncarg
NCARG_NCARG=/home/felix.carrasco/NCL/lib/ncarg

because they will be found automatically simply by the fact you set:

NCARG_ROOT=/home/felix.carrasco/NCL

There are two possible reasons why the ESMF_RegridWeightGen is trying to
get picked up from the anaconda directory.

One is that /opt/anaconda2/bin may be on your search path before
/home/felix.carrasco/NCL/bin.

The other is that you may have the environment variable ESMFBINDIR set to
/opt/anaconda2.

To check your PATH, type:

echo $PATH

If the /opt/anaconda2 path is first, then fix this in your appropriate
/home/felix.carrasco/.XXXX file where PATH is being set. You will need to
log out and log back in for this to take effect.

If ESMFBINDIR is set to the anaconda2 path, then again, you will need to
fix this in your appropriate .XXXX file.

I recommend not setting it at all, as long as $NCARG_ROOT/bin is on your
search PATH before /opt/anaconda2/bin. Or, you can try setting it to
/home/felix.carrasco/NCL/bin,
but I don't like this solution because if you install NCL to a different
location, you will need to remember to change this setting.
