Re: NCL WRAPIT question

Jeffrey,

A couple of things: If you are using a recent version of NCL, like
5.2.0, I'm not sure if you'll be able to use g77 to compile this code,
and link against NCL libraries which were compiled with gfortran.

That said, I think your error is simply that you need to help WRAPIT
find the "libg2c.xxxx" library.

You might be able to type:

    locate libg2c

to find the library. Note the path, and then use "-L" on the WRAPIT
line to indicate the path:

    WRAPIT -L /path/to/file PotentialIntensity.f

The "/path/to/file" will need to be replaced by the correct path, of
course.
