Re: Shapefile Example Not Working

My apologies, I didn't read the error closely enough! I think you
may have
a version of NCL that was built without shapefile support. I'm not
sure I understand
this, though, because I thought all the 5.1.1. precompiled Linux
binaries had
shapefile support built in.

Do you know if you are running a version of NCL that was compiled
from source
code? If so, it's possible that shapefile support was turned off.

I'll keep quiet now, because I just read an email that says Rick will
try to
help you. :-)
