activating history in Python 2.3.4

[Riko Wichmann]

dear all,

lately, I installed Python 2.3.4 from sources (after having 2.2 for some
time).
However, running Python interactively, I cannot recall the histroy of
command with cursor-up or down anymore (just get ^[[A for example).
As far as I could find out, it has something to do with GNU readline.
When I do

import readline

Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named readline

things seem to be clear. However, since my old Python 2.2 seems to have
readline it means, gnu readline is in principle available.

How can I activate history, or where do I get the readline module from?

Thanks and cheers,

Riko

Make sure that the readline development headers and libraries are
installed on your system.

On Debian Linux, for example they're called libreadline4-dev. On
RPM-based Linux distributions, they're called libreadline-devel or
similarly.

well I installed readline5.0 from source, so all necessay headers are
there. but still, no module named readline ....

I configure python explicitly with --with-readline and everything seems
to be fine. I find in the config.log:

ac_cv_lib_readline_rl_completion_matches=yes
ac_cv_lib_readline_rl_pre_input_hook=yes

and no other complains in connection with readline. However, looking in
the lib/python2.3/lib-dynload after make, make install, there is only a
readline_failed.so and an xreadlines.so ... ??

Any other ideas would be greatly appreciated!

Cheers,

Riko

Gerhard,
I wonder if it's your terminal that is causing the problems? If you're
using xterm, try switching to aterm, konsole or gnome-terminal and see
if the behaviour is the same.

Hi Andrew,

nope, it's not the terminal, xterm, konsole and gnome-terminal behave
the same.
