Can you also compile readline module in python ?

http://code.google.com/p/python-for-android/issues/detail?id=6

Is anyone working on this? I tried to get this working by compiling with
the NDK as described in the wiki. It requires libncurses.a, which I
eventually figured out using this blog for guidelines:
http://credentiality2.blogspot.com/2010/08/compile-ncurses-for-android.html

Then there was an issue not being about to find setpwent or getpwent. I
brazenly deleted the offending code and eventually got an egg.
Unfortunately, it looks like something is wrong with the library I built
with NDK.
When I "import readline" I get:
ImportError: Cannot load library: load_segments[928]: 600 failed to map
segment from 'readline.so' @ <some assembly stuff here>

At this point I'm pretty well stuck, maybe someone else will know what to
do.

Added to Python3
Will be looking to backport to Python2 in the next few weeks.

I would actually rather have 2.6 with readline than 2.7 without it. Does
that make sense?

[Robbie Matthews]

If I get stuck into the 2.7 project, it's one of the first things I intend to add.
Unfortunately, 2.6.2 has such an eccentric build that incorporating the readline was very difficult.
It'll be easier to incorporate in 2.7.

I tried to compile readline 6.2.2 using third party library but it says
import error cannot load library find library 1226 : 7498 readline.so
failed to load previously.

any update for readline support on python 2.x?

I compiled libreadline.so and libhitory.so for Android using c4droid (not
ndk!), and checked them with Python-ctypes, and they work. To compile
readline, on Bionic, a patch is necessary for systems without setpwent,
which I got from this bug report [1]. The shared object libraries are
attached here as "rl-6.2_arm_linux_androideabi.tar", & the patch is also
attached as "readline-6.2-complete.c.patch". Unfortunately I was not able
to compile a working "readline.so" from the Python-readline-6.2.4.1
package; I always got "library not found"/"failed to load previously"
errors. However, I am working on a pure (Python only) wrapper for the
shared object libraries using Python-ctypes that is closely based on
Python-readline. It is called "purereadline" [2] and is hosted on github. I
hope when it is completed it will work or I'll be very bummed. FYI: I can't
think of any reason that the Python-readline package shouldn't work except
that I am too lazy to actually build Python for Andriod, and so have valid
python.h and pyconfig.h files. It would be very nice if future "Python for
Android" versions had a "dev" download that included the headers necessary
to build extensions.

See readline build Robbie did for Python 3, this should be easy to port on
android-python27, unfortunately I have no time to do this right now but is
in my todo. Let me know if you succeed and would like to commit your code
in the project.

The pure-python readline code is on github, but it is still about 100 lines
and some testing short of being ready.

Hai, Finally I compiled a working readline module for python2.7.3
The attached file is can be applied to original python2.7.3.tar.gz

But I only compiled python ,readline , and ncurses.So there are lot of
modules which is un available .includes ctypes. Because I concentrated on
readline.

I used gdb sever to debug python shared libs. It is a great tool.

I choose python2.7.3 because I couldnot get the source file which
correspond to python_r16.zip available at Download section.This version
contains almost all module except readline.
Here I have only readline module.

So any one can post headers corresponding to python_r16.zip.

Sorry for my language.

Hai ,
This the reppo for python2.7.3 with readline support

I finally got readline working for the KBOX environment port of Python
3.5.x thanks to the patch posted here plus a couple of post-configure hacks
to the shlib/Makefile.

For reference purposes, the "issue" is being tracked here:
http://bugs.python.org/issue23496. Once I figure out where or if to submit
readline stuff, I'll post the link here as well

Hi,
I enabled readline module for python 2.7.9.
patch https://bugs.python.org/issue21390 was also needed.

https://github.com/kuri65536/python-for-android/releases/tag/r24

But python 3.4 is not yet.
Thank you.
