python on mini

hi im tring to install phyton on mini im following the steps of this link:

http://www.ailis.de/~k/archives/19-ARM-cross-compiling-howto.html

i made the cross compile with out mistake (i only saw some warnings)

at the end i did this:
 
To install python type this:

# make install prefix=<Root-directory>/usr \
HOSTPYTHON=./hostpython \
BLDSHARED="arm-linux-gcc -shared" \
CROSS_COMPILE=yes

Notice that you have to specify /usr behind the path to the targets
root-directory.

You are done. You should now have a complete working cross-compiled Python
suite. Copy it to your target machine and be happy

MY DOUBT ITS what folder or files should i copy to the mini2440?

and .. how exactly i know the python its working well on my mini? (i never
have worked with python before).

Thanks to every body

hi i copied the all folder to the mini and after that i put on console
./python

and appears me this:

Python 2.2.1 (#1, May 24 2010)
GCC 4.3.2 on linux2

Type help, copyright or license for more information.

then should i assume that i made a good installation of phyton? 

(forgive my ignorance i never have use phyton before)

it is ok good and i hope this can be useful for someone else :)

What size flash have you got in your machine?  After cross-compilation I
had somewhere around 64M, which was a bit large for my 64M machine.  I
understand one can strip out a lot to reduce size.  Did you do that?  If
so, what did you remove?

my phyton folder size its 71Mb im luck because my mini board size its 128m

however 71mb its to much for my mini2440 i want to reduce that size, but im
not sure yet what i have to remueve.

i would like that you tell me if you find the way to reduce it

thanks!!

Did you find this tutorial:

http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html

I see at the bottom there are some suggestions for reducing size.

Hey David, can you put your python binary package on some repository so
people here can download an run it?

thanks

david,

Following the link in my previous post.

***
cd _install
rm -rf include
rm -rf share

cd lib
rm libpython2.6.a  (wasn't present)

cd lib/python2.6
rm -rf `find . -name test`
rm `find . -name *.pyo` (didn't work, wrong syntax)
rm `find . -name *.py`  (didn't work, wrong syntax)

rm *.pyo (worked for me)
rm *.py  (worked for me)
 
cd ../../bin
rm python2.6
***

Got _install down to 31.5M

Now, the line
ppc_6xx-strip python

I couldn't find the equivalent for the arm9

Good luck,
dave

davef i tried to do my compilation following your link but i couldnt able
to do it

how ever i tried to do my own compilation (the one what i put above) and
now im having some trouble with the last step:

# make install prefix=<Root-directory>/usr \
HOSTPYTHON=./hostpython \
BLDSHARED="arm-linux-gcc -shared" \
CROSS_COMPILE=yes


its showing now this mistake:

bash: Root-directory: No existe el fichero ó directorio

i dont know what im doing now wrong, however the crosscompile file it
working as worked the first one i did (so strange dont you think?)

./python

and appears me this:

Python 2.2.1 (#1, May 24 2010)
GCC 4.3.2 on linux2

Type help, copyright or license for more information.

both files when i type characters like  (  on mini it throws doubles ((
and when i type supr it shows me [[3

but when i type credits or copy right it showsme that and if i type
print 'hello world' it shows me hello world

i had never work with python so i dont know if this problem (supr) its
normal or i did a wrong compile

the size of my file its:40.7Mb

dave your does you python has this problems? could you help me with this?


Flavio i suggest you follow the instrution of my link or davef's link maybe
you will not have my problems.

and also suggest that the first who put this work well  put this python
binary package on some repository.

davef when i try to compile following your link i have problems in this
part:

CC=ppc_6xx-gcc CXX=ppc_6xx-g++ AR=ppc_6xx-ar RANLIB=ppc_6xx-ranlib
./configure --host=ppc-linux --build=i686-pc-linux-gnu --prefix=/python

make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen
BLDSHARED="ppc-linux-gcc -shared" CROSS_COMPILE=ppc_6xx-
CROSS_COMPILE_TARGET=yes

make  install HOSTPYTHON=./hostpython BLDSHARED="ppc-linux-gcc -shared"
CROSS_COMPILE=ppc_6xx- CROSS_COMPILE_TARGET=yes
prefix=~/Python-2.6.5/_install

im coping and pasting these lines and its showing me this:

/Escritorio/Python-2.6.5$ CC=ppc_6xx-gcc CXX=ppc_6xx-g++ AR=ppc_6xx-ar
RANLIB=ppc_6xx-ranlib ./configure --host=ppc-linux

ops i forgot my python files can be run from my USB in this way the size
shouldnt be so important.

david,

"Size shouldnt be so important".  Why spoil all the fun?!

Correct me if I am wrong, but it looks like you are cross-compiling for a
ppc rather than arm9.

Here are the commands I used:

./configure --host=arm-linux --build=i686-pc-linux-gnu --prefix=/python
--enable-shared --disable-ipv6 --disable-dynamic-extension
CFLAGS="-march=armv4t -mtune=arm920t -Os -lpthread -lrt" LDFLAGS=${LDFLAGS}

make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen
BLDSHARED="arm-none-linux-gnueabi-gcc -shared" CROSS_COMPILE_TARGET=yes

make  install HOSTPYTHON=./hostpython BLDSHARED="arm-none-linux-gnueabi-gcc
-shared" CROSS_COMPILE_TARGET=yes prefix=~/Python-2.6.4/_install
***

Try these and let me know how you got on.

Dave

hey dave, can you put your python somewhere so i can download it?

ups david, sorry, i didnt read your message to me. Okay so its time to try
to cross compile it right now.

flavio,

It is untested so I think posting it would just waste people's time.

For now, if you get a successful compilation following the aforementioned
tutorial using my script mods you will be as far as I am.

I need to do some study on 2D plotting capabilities in Python before going
any further.

OK?

dave

Ok, i compiled python 2.6.5 and it works with a couple of built-in libs
(os, sys and others).

threading, time and some don't work, but if you want to see python running
on your friendlyarm you can download this binary and test:
http://dl.dropbox.com/u/6159957/Python-2.6.5-FriendlyARM.tar.gz

its important to say that it wasn't tested much and i'll work more to get
all modules working.

flavio,

Excellent.  I'll check it out tonight after work.  

Did you find a strip command for ARM9?

Could you post the steps you took after the 3 commands I posted?  Or did
you use a different method?

Regards,
dave

flavio i checked your python and it has the smae problems as mine

if i put "(" it appears doubles

if i use delete appears = ?

if i use supr [3

davef im having some troubles when i execute your second line:

make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen
BLDSHARED="arm-none-linux-gnueabi-gcc -shared" CROSS_COMPILE_TARGET=yes

what could i be doing wrong? thanks

david,

Sorry, I can't really help with that.

What host distro are you using?  I did mine on Ubuntu 9.04.

Dave

Davef im using ubuntu 9.1, maybe i have installed wrong my toolchain i only
installed the arm-gcc compiler do i need to install some thing else on my
pc??

The excuse what i installed was arm-linux-gcc-4.3.2 toolchain from this
link:

http://equallybad.blogspot.com/2010/02/project-how-to-setup-default-dev-...

is it enought with that or do i need some thing else thanks!!

david,

Just read through this again and was wondering if you had made any
progress.

In order to get Ubuntu to compile stuff you need:
sudo apt-get install build-essential automake autoconf libtool

Also, to be able to look at <menuconfig> when doing kernel work you need:
ncurses-dev ? or ncurses something.  

I think those are the only extra things I had to drag it.

Good luck

davef i formated my pc i made the process again but following your
instrution i couldnt complet the cross compilation.

the only way i could made it was following the instrution of the first
link:

http://www.ailis.de/~k/archives/19-ARM-cross-compiling-howto.html

it compied with out mistakes but has the same problems than the other at
the moment i typed delete or supr

although if i type copyright it shows me 

all rights reserves ....
...
,..

can you upload you file? i want to check if it has the sames issues

I'll look into placing it somewhere so that you can download it.

Haven't done it before!

Dave

david,

Try this.

Download-Link: http://rapidshare.com/files/397383730/Python.zip.html

Now, the issue about stripping Python.  Appears it is the normal strip
command, but what the switches are used and what files you want to strip I
haven't a clue.

Good luck,
Dave

davef, 

yes it works as my python, and also it has the same size.

thanks friend

davef i forgot what python's version did you compile?

2.6.5

thanks friend
what i compile was 2.2.1

I downloaded the python that Davef compiled and it seems to be working
except for a few modules. 

I'm trying to install pySerial and the install bombs out with this error:
error:  Invalid python installation unable to open
/usr/local/lib/python2.6/config/Makefile (no such file or directory)

If I just copy pySerial into the folder then I get hung up on these modules
when I do an import on serial:

fcntl
termios
struct
select
time


Thoughts?

Don't know if the "unable to open /usr/local/lib/python2.6/config/Makefile
(No such file or directory)" problem has been solved, but what you need to
do is install python26-devel.  I got the same error and installing it fixed
it.

Is there any new progress on Python to mini2440.

I have been trying to compile Python-2.7.2 / Python-2.7.3 from this site

http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html

But with no luck.

Any one that have working Python-2.7.* at all?
