I'm not aware of anyone ever using gfortran with the netCDF package.
g77 has been used, however.

It appears from the above that gfortran IS NOT a Fortran-77 compiler.

It appears from the above that gfortran IS a Fortran-90 compiler.

The above indicates that the C compiler didn't know what Fortran
argument-passing conventions to use.  This information must be given to it
manually by defining a certain C macro in the CPPFLAGS environment
variable before executing the configure script.

Assuming that gfortran uses the same argument-passing conventions that
g77 uses (if it doesn't, then the "make test" will fail) then please try
the following:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 described near the end of the file
        INSTALL.html.

    3.  Define the C macro "f2cFortran" in the environment variable
        CPPFLAGS:

            export CPPFLAGS=-Df2cFortran

        or

            setenv CPPFLAGS -Df2cFortran

        depending on your user-shell.

    4.  Perform steps 6 through 9 described near the end of the file
        INSTALL.html.
