Without having seen the actual contents of the netlist file, I can only
try and guess that the problem is caused by one or more of the following
reasons:

1. You might be running
        gnucap <file>
instead of batch mode
        gnucap -b <file>

2. The plain netlist as converted by gnetlist does not contain probes,
i.e. there are no .plot/.print cards in the file.
You should add them manually.

3. The type of analysis is not specified, i.e. you don't have .dc or .ac
or simmilar commands in the file.
You should add at least one of them.

If there is still no output, you might consider sending us the circuit
file so we could investigate the cause for such a behaviour.
