run pypy on kindle

[kdusr]

last week I jailbreaked my KV, and installed python on it, ( https://www.mobileread.com/forums/sho...d.php?t=153930 )

wrote a test script with UI and touch keyboard , it works petty good on kindle, but a little bit slow

then I try to install pypy on kindle, because it 7-10 times faster than standard python and new version of pypy support Tkinter UI module

there are three diff version of pypy for ARM cpu,
http://pypy.org/download.html
ARM Hardfloat Linux binary (ARMHF/gnueabihf, tar.bz2, Raspbian) (
ARM Hardfloat Linux binary (ARMHF/gnueabihf, tar.bz2, Ubuntu Raring)
ARM Softfloat Linux binary (ARMEL/gnueabi, tar.bz2, Ubuntu Precise)

i do not know which version can be matched with kindle,
then I tried all of them, but do not work

what i did:
download pypy package, unzip to /mnt/us/pypy folder, add a python env file in the folder
python env setting as follow:
#!/bin/sh
export PATH=/mnt/us/pypy/usr/bin/:$PATH

then
try to run ./mnt/us/pypy/bin/pypy
got error, can not find pypy

pypy folder structure :

pypy
....|------bin
............|------pypy
............|------libpypy-c.so
....|-------lib_pypy
................|..blalala
....|-------lib-python
................|..blalbla
....|-------site-packages
....|-------include

anyone can give me a hint? how to make pypy running on kindle, thanks!

1) Your Kindle is softfloat, like all others.
2) Do not include a leading period when giving a full path.
I.E: . == current directory, not root directory of the file system tree.

thanks knc1!

looks this version of pypy should be matched with kindle,
ARM Softfloat Linux binary (ARMEL/gnueabi, tar.bz2, Ubuntu Precise)

setup path env , try to run but got this
error while loading shared libraries libffi.so.6
can not find libffi.so.6

error while loading shared libraries libffi.so.6
can not find libffi.so.6:(

1) In the advanced editor, scroll down, check "disable smilies" in text.

2) So include libffi.so.6 from the same release.

3) Note: You may need to take your libraries and applications from an earlier release than Precise. In fact, it is better to use Debian, they are a better match to what Lab126 uses.
The libc on your Kindle may be too old to support code for the Precise release.
To tell, just run it (libc is both a library and an executable).
OR - just wait for the 'symbol not found' errors to show up.

[kdusr]

yes you are right, pypy 5.41 Precise is too new, checked my KV /usr/lib/, found libffi.so.5

then I try to install earlier release
https://bitbucket.org/pypy/pypy/downloads

pypy-2.0-alpha-arm-armel.tar.bz2

this release use libffi.so.5, but another error popup :
Error:libtinfo.so.5: cannot open shared object file: No such file or directory

searched google, on kindle, libtinfo called libncurses
then I try this:
su
ln -s /usr/lib/libncurses.so.5 /usr/lib/libtinfo.so.5
ln -s /usr/lib/libtinfo.so.5 /usr/lib/libtinfo.so
but does not work , when i run pypy, same error popup again

it looks difficult to run pypy on kindle (for a linux fresher)
ps : is that possible ? install some lib so files to kindle /usr/lib/ folder??

[kdusr]

but I really want to transfer this python script to pypy on kindle

Do you have USBnetworking installed?
Then you also have nano installed, problem solved.

You never described what your panel's use was.
So I only guessed file management.

You don't have to waste time on that, we already have:

kTerm : on-Kindle terminal with command line access
MC (Midnight Commander) : file management
ssh : command line access

Otherwise, do as I first told you, draw from Debian Jessie.

Also, twobob has written a lot of scripting in support of locating all dependences in a Debian application.
Use either our Wiki master index, or our search to search his posts to find it.

You will spend a lot less time re-inventing wheels if you take the advice that you requested.

as you know, python is fast for development but running slow, thats why I want to install pypy on kindle, if pypy can run on kindle, it would be a general power tool like java, c,
I just surprise until now why no one try config pypy to run on kindle
