Yes, I forgot about the -b flag.
That is the appropriate one to use.

Unfortunately, ncgen has always treated
the no flags case as being just a syntax
check. I agree with your intent, but
we are captives of history and back compatability.

I think ncgen could still treat no flags as a syntax check, but use of
-b or -o specifying an output file means a netCDF output should be
generated.  In that case, I don't see the need for specifying a "-k"
when the type of output can be inferred from the CDL.

This request was actually entered a few months ago in Jira ticket
NCF-124:

  https://www.unidata.ucar.edu/jira/browse/NCF-124

I don't think it would violate our backward compatibility commitment,
which is about APIs and data.

Hi,

I built netcdf-4.2-rc1 and I was not able to create a file using ncgen unless I included the '-k kind' option. With this option omitted, nothing happens.

I hope this is not intentional because it would be a step in the wrong direction. My goal is to *never* use the -k option, but rather to use the _Format attribute within the CDL to define the output file type at run-time. Based on earlier discussions I've had with Unidata, and some documentation I've seen, this was the intent of the _Format attribute. Using -k would override what is in the CDL. Now I'm not sure what to think.

Thanks ...
