I have readline-4.3-4 it includes these lines as in yours.

oct-rl-edit.c contains the line

#include <readline/readline.h>

I suspect that my readline. is in the wong place.  Can you tell me what should 
be where?  Where should I be installing things from.

When I try this it just returns "no symbols".

[sue at localhost lib]$ ls /lib/libread*
/lib/libreadline.so@    /lib/libreadline.so.4.1@  /lib/libreadline.so.4.3
/lib/libreadline.so.4@  /lib/libreadline.so.4.2@
[sue at localhost lib]$ nm libreadline.so | grep -w 'rl_terminal_name'
nm: libreadline.so: no symbols

I think this is there. (I'm a little confused and very tierd at this point)

I suspect this may be a "things are in the wrong place" error too.

[sue at localhost octave-2.1.50]$ rpm -q readline
