Re: WRAPIT question, several subroutines

Hi Larry,

I think that "-fPIC" should be the default if you are using NCL 5.2.0 or later.

How are you invoking WRAPIT? Can you add "-d" to the WRAPIT line so we can see the full output? This might give some clues.

As Rick eluded to below, this is hard to debug without seeing your code.
