Sorry, I’ve never seen this before. My first guess would be that something might have failed earlier on in the build and maybe that is why it deletes libpython2.7.a

Sorry, I’ve never seen it before. My guess would be something to do with the root filesystem because that is the major difference between android and linux systems.

Good luck!
Paul

Trying to follow the tutorial. Compile on Ubuntu 10.04 32-bit for ARM CPU (not for android)
Config part works:
CC=arm-cdcs-linux-gnueabi-gcc CXX=arm-cdcs-linux-gnueabi-g++ AR=arm-cdcs-linux-gnueabi-ranlib ./configure –host=arm-linux –build=x86-linux-gnu –prefix=/python

Now for building:
make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen BLDSHARED=”arm-cdcs-linux-gnueabi-gcc -shared” CROSS_COMPILE=arm-cdcs-linux-gnueabi- CROSS_COMPILE_TARGET=yes HOSTARCH=arm-linux BUILDARCH=x86-linux-gnu

And I am getting an error (including few lines just before the error):
arm-cdcs-linux-gnueabi-gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -c ./Modules/xxsubtype.c -o Modules/xxsubtype.o

rm -f libpython2.7.a
arm-cdcs-linux-gnueabi-ranlib rc libpython2.7.a Modules/getbuildinfo.o
arm-cdcs-linux-gnueabi-ranlib: ‘rc’: No such file
arm-cdcs-linux-gnueabi-ranlib: ‘libpython2.7.a’: No such file
arm-cdcs-linux-gnueabi-ranlib: Modules/getbuildinfo.o: File format not recognized

Modules/getbuildinfo.o is there and is of ARM ELF file format.
It also looks like libpython2,7.a is removed before being used????

make: *** [libpython2.7.a] Error 1

Thanks for the link , [http://mdqinc.com/blog/2011/09/cross-compiling-python-for-android/]. I successfully built python for Android. I ported into my target board….I can execute few python commands like, python -V and python –help.

But, python prompt is not coming on target..and idea why it is so.. any tricks for working ??
Also, I wrote simple python script which imports os, random and time modules….
Seems only os module is working but others are not working,,,can you please suggest some ideas what do i need to do to make it work??

I have set the environment variables too..
PYHTHONHOME = /system/lib/python2.7
PYHTHONPATH = /system/lib/python2.7

Thanks for the help provided….
Now I’m looking into the link provided by you [http://mdqinc.com/blog/2011/09/cross-compiling-python-for-android/]. I have done good progress in compiling the Python for the Android.

Thanks for the help ….

My first guess is that you are still missing libraries that python is looking for:
/system/bin/sh: python: not found

The Android root filesystem is not standard Linux and therefore I cannot help. You may want to look at other articles such as:

Thanks for the reply.

I have copied the entire built python directory to my target device under /system/usr
I have set the path environment variable like this …
export PATH=$PATH:/system/usr

My target is connected to my Ubuntu machine(10.04) and able to communicate to target over serial port using minicom. Using minicom, i have opened the shell prompt of the device.
In shell prompt, I’m trying to execute python.
If I execute the python command, I’m getting python not found !!!

Below is the snapshot of the error
==========================================
root@android:/# echo $PATH
/sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin:/system/usr
root@android:/# python
/system/bin/sh: python: not found
127|root@android:/# cd /system/usr/_install/bin
root@android:/system/usr/_install/bin# python
/system/bin/sh: python: not found
=============================================

Do I need set any other environment variables, or do I need to copy any other lib files from host to target.
Please let me know.

For your info : My target device has the Android’s Ice Cream Sandwitch OS running.

Regards,
Shekhar

Could you show me how you are running python? Are you running python from /_install/bin? Is it on the PATH?
