Can you also compile readline module in python ?

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?

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.

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.
