The problem is that _rl_clear_screen is "private" and is not exported in cygreadline.dll. As you and I both found out, simply removing the leading underscore is the "Wrong Thing". There are a number of solutions to this problem, including: a) building octave without readline support, b) building your own dll with this symbol exported c) using the static libreadline.a d) finding a way to use rl_clear_screen e) getting someone else to do (b) for you Option (a) is easy as there is a configure option for this. Option (c) is pretty easy. Configure octave with "CFLAGS='-DREADLINE_STATIC -O' Change -lreadline to /usr/lib/libreadline.a in Makeconf make The rest are left as an exercise. +++++++++++++++++++++++++++++++++++++++++ (Mr) David Billinghurst Comalco Research Centre PO Box 316, Thomastown, Vic, Australia, 3074 Phone: +61 3 9469 0642 FAX: +61 3 9462 2700 Email: David.Billinghurst@riotinto.com -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
