This is a little awkward at the moment, because of the recent
changes to the libgretl API. I'm making available two versions
of a sample NLS program, at
http://www.wfu.edu/~cottrell/tmp/nls-new.c
http://www.wfu.edu/~cottrell/tmp/nls-old.c
Use the first of these if you're working with current CVS
libgretl (since 2011-07-11), otherwise use the second.
If you compare the two, you'll see that the new API is nicer!
