Odd.  Defining the "f2cFortran" macro should have sufficed to correctly
build the Fortran-77 interface on a Linux system.  It should cause
external C functions like "nf_create" to become "nf_create__" so that
they can be called by Fortran code.

That is as it should be.  The netCDF build process assumes that the
Fortran compiler will convert calls to "nf_create" into calls to
"nf_create__" when the "f2cFortran" macro is defined.  This is not a
mistake.

How?  If it's not too much trouble, would you please do the following:

    1.  Go to the top-level source directory.

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

    3.  Ensure that the environment variable CPPFLAGS contains the
        string "-Df2cFortran".

    4.  Perform steps 6 through 8 near the end of the install file.

I'm particularly interested in the files "configure.log", "make.log",
and "test.log".
