Andre,

You say that you are compiling your application program with pgf90,
yet you have posted the output from a gfortran command.  This problem
is not related to the Netcdf library.  You really need to have control
over your local compile environment.  Please ask your local fortran
consultants for help.

The first error shown, Unclassifiable statement, is because the
include file netcdf.inc uses fortran 77 style comments with "c" at the
start of the line.  This is incompatible with the -ffree-form compiler
option, at least with gfortran.  Free form uses exclamation points at
the start of comment lines, not "c".

Furthermore, this copy of netcdf.inc is not from the Netcdf 4.1.3
distribution!  It looks like either a modified copy in which
exclamation points at the start of comment lines were replaced with
the letter "c", or possibly a copy from an older Netcdf release
(speculation).  Ironically, the original netcdf.inc in 4.1.3 would
probably work correctly with this particular gfortran command.

It is very possible that a large number of "unclassifiable statement"
errors caused the include file to be aborted in the middle.  This
would explain the later symbol errors.  So I recommend that you first
get your compile command under control, then revert to the original
include file from the Netcdf distribution.

Please reply to the user list only!
