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. PC与开发板文件传输
tftp: tftp -l path/to/filename -r filename -g 192.168.*.*
3. 文件拷贝
or export PATH=/your/path/bin/:$PATH # OK210开发板会报错
4. 设置Python相关环境变量
以Python2.7.x为例。
export PYTHONHOME=/your/path/ #export PYTHONPATH=$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 /lib
1. 按照上面Paul Gibson给的Cross Compiling Python for Embedded Linux , 但是import sqlite3会报错,原因暂不明。
试了一些解决办法,尝试未果,可能是lib_dir路径问题:

3. debian平台成功。 http://www.friendlyarm.net/forum/topic/2731
参考:
1. cross compile python, busybox, flex, bash and so on, ARM cross-compiling howto
2. 网上一个给力的例子,python-2.6.6:
Click and run python cross compiling for Embedded ARM Linux
3. 在友善之臂Linux系统中使用python http://112.124.9.243/?p=285
4. 移植python3到ARM平台的OK6410开发板 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
