Hi Larry,

Usually when you get an "undefined symbol" error message coming out of
a *.so
file that is subsequently loaded by NCL, this means either you are
calling a subroutine
that is defined in some external library or Fortran file that is not
being included on the WRAPIT
line, or else something is just plain wrong with WRAPIT and it is not
creating the
*.so file.

In this case, it's complaining about the symbol "extract". Is this the
name of the subroutine
that you have the "C NCLFORTSTART" and "C NCLEND" comment blocks
around, or
is it an internal subroutine being called by your Fortran file?

If you could email me the extract.stub and extract.f99 files, I'll take
a look.
