ng4ex

Hi,
    I'm newer using NCL, allow me to ask some naive question. Thanks.
    I'm following the document about the ng4ex. I can use ng4ex cn03c. But while typing ng4ex cn03f, appeared this:

    NCAR Graphics High Level Utility Fortran Example <cn01f>

  Copying cn01f.f
  Copying cn01.res

Compiling and linking...
gfortran -fPIC -fno-second-underscore -fno-range-check -O0 -o cn01f cn01f.f -L/usr/local/ncl/lib -I/usr/local/ncl/include -lhlu -lncarg -lncarg_gks -lncarg_c -lX11 -lXext -lgfortran -lm
/usr/lib/gcc/i486-linux-gnu/4.3.3/../../../../lib/crt1.o: In function `_start':
/build/buildd/glibc-2.9/csu/../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld ·µ»Ø 1
Executing <cn01f>...

./cn01f: Command not found.

Finished executing <cn01f>...
   
    Can anybody tell me what the problem is?

    Regards,
    Liu.
