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

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

　　 or  export PATH=/your/path/bin/:$PATH   # OK210开发板会报错

•        拷贝serial、django等python库拷贝到/lib/python2.7/site-packages/目录下。
  

　　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
