- I'm having some trouble with either of the line editing libraries available
- to me. If I build Python with libreadline, I get "staircases" in my
- interpreter output:
-
- >>> s = 1
- >>> a = 3
- >>> etc.
-
- So I figured I'd give Rich Salz's editline a try. It seems to be missing a
- couple readline functions. When I link I get:
-
- myreadline.o: Undefined symbol _rl_insert referenced from text segment
- myreadline.o: Undefined symbol _rl_bind_key referenced from text segment
-
- I'm running on BSD/OS 2.0 with GCC 2.6.3 as the compiler. My configure line
- was
-
- ./configure --with-readline=/home/dolphin/skip/src/editline \
- --with-dl-dld=/home/dolphin/skip/src/dl-dld,/home/dolphin/skip/src/dld
-
- For editline I tried several things before arriving at something that does
- work ... sort of. First I commented out the tab key binding in Python's
- Parser/myreadline.c then had to fiddle with editline.c to get tabs to
- insert. The diffs below seem to work, but have no notion of tab stops (I
- like 4-char tab stops).
-
- I'd be grateful if anybody had a solution to the readline staircases or a
- better solution for making editline work.
