If you invoke ncgen with no options, as in 

  ncgen now.cdl

it just checks the syntax of the CDL file and emits error messages for
any syntax errors.  In order to generate C code, you need to use the
"-c" option:

  ncgen -c now.cdl > now.c

The ncgen options are documented in the netCDF users guides or in the
ncgen man documentation included in the src/ncgen/ncgen.1 file in the
source distribution, or online at

 http://www.unidata.ucar.edu/cgi-bin/man-cgi?ncgen

It sounds like you're on the right track ...
