Python ported to the arm platform-EEWORLD

Collect

1. Cross-compile Python

　　见Cross Compiling Python for Embedded Linux

CC=arm-linux-gcc CXX=arm-linux-g++ AR=arm-linux-ar RANLIB=arm-linux-ranlib ./configure --host=arm-linux --build=x86_64-linux-gnu --prefix=/root/tftpboot/Python-2.7.3

make HOSTPYTHON=./hostpython HOSTPGEN=./Parser/hostpgen BLDSHARED="arm-linux-gcc -shared" CROSS_COMPILE=arm-linux- CROSS_COMPILE_TARGET=yes HOSTARCH=arm-linux BUILDARCH=x86_64-linux-gnu

make install HOSTPYTHON=./hostpython BLDSHARED="arm-linux-gcc -shared" CROSS_COMPILE=arm-linux- CROSS_COMPILE_TARGET=yes prefix=/root/tftpboot/Python-2.7.3

2. File transfer between PC and development board

　　tftp： tftp -l path/to/filename -r filename -g 192.168.*.*

3. File copy

　　cp /your/path/bin/python2.7 /bin/python

or export PATH=/your/path/bin/:$PATH # OK210 development board will report an error

Copy serial, Django and other Python libraries to the /lib/python2.7/site-packages/ directory.

4. Set Python related environment variables

　　Take Python 2.7.x as an example.

export PYTHONHOME=/your/path/
#export PYTHONPATH=$PYTHONHOME:$PYTHONHOME/lib/python2.7:$PYTHONHOME/lib:$PYTHONHOME/lib/python2.7/site-packages
#export PATH=$PATH:$PYTHONHOME:$PYTHONPATH

5. sqlite3

Building SQLLite and other dependancies

Thanks to Lothsahn’s 2.7.3 patch, it is now possible to build sqlite3, bz2, gz, ssl and ctypes.  Lothsahn provides the following instructions:

To do the compilation, the dependencies must be in the include and lib folder one path up from the python install.   For example:

/include <– header files go here

/lib <– shared object files go here

/Python-2.7.3 <—Python sources go here during compile

Dependencies include libffi, sqlite, openssl, bzip2, zlib, etc.

1. Follow the Cross Compiling Python for Embedded Linux given by Paul Gibson above , but import sqlite3 will report an error, the reason is not clear yet.

I tried some solutions but failed. It might be a problem with the lib_dir path:

　　Removing other search paths from the setup.py, but the one i had the ARM compiled library in, made it work. 测试也未通过。

3. Debian platform is successful. http://www.friendlyarm.net/forum/topic/2731

reference:

1. cross compile python, busybox, flex, bash and so on, ARM cross-compiling howto

2. A powerful example on the Internet, python-2.6.6:

Click and run python cross compiling for Embedded ARM Linux

3. Use python in the Friendly Arm Linux system http://112.124.9.243/?p=285

4. Porting python3 to the OK6410 development board of the ARM platform http://www.51bigfool.com/%E7%A7%BB%E6%A4%8Dpython3%E5%88%B0arm%E5%B9%B3%E5%8F%B0%E7%9A%84ok6410%E5%BC%80%E5%8F%91%E6%9D%BF.html

Attachment:

　After stripping, the debugging information will be removed and the executable file size will be much smaller. The command is as follows:

　　　　# arm-linux-strip file

　　　　Where file is a binary file compiled by arm-liunux-gcc.

./configure --host=arm-linux CC=arm-linux-gcc AR=arm-linux-ar STRIP=arm-linux-strip RANLIB=arm-linux-ranlib
Cross-compile of sqlite3
- 　　# CC=arm-linux-gcc ./configure --prefix=/your/path/sqlite-3.7.14 --host=arm-linux --disable-tcl
  　　#make && make install
