[ncl-talk] WRAPIT warnings

Wed Jun 8 11:21:05 MDT 2016

Ah, ok.  After correcting the typo on my end as well, I can load the .so
file, so the routine should work now.  You should be able to execute in NCL
with:

external SIZES2 "/path/to/sizes2.so"
SIZES2::cldsi(...)

As for the warning, it's just complaining about a missing function
prototype, which is happening under the hood in the WRAPIT stuff.  We'll
take a look at that on our end to see if there's something we can do to
prevent the warning in the future, but it shouldn't impact you.
