在arm上安装python2.6全部过程

在arm上安装python2.6全部过程
1. 平台：
    platform：mini2440
    host system： ubuntu10.10
    target system：Linux mini2440 2.6.29.4
    source：python-2.6.2

2. 编译源码：
  ./configure     \  
    --host=arm-linux    \  
    --prefix=`pwd`/build
   make;make install

3. 安装到arm
(1)将第二步产生的python可执行文件拷贝到arm上，路径为：/work/rootfs/work/python/bin中；
(2)将源码中的Lib文件下的所有文件拷贝到：/work/rootfs/work/python/lib/python2.6中；
(3)将可执行文件python所在的目录添加到环境变量PYTH中：
PATH=/work/rootfs/work/python/bin:${PATH};export PATH
(4)添加一个环境变量，这个是指定python所需要的py文件：
PYTHONHOME=/work/rootfs/work/python/;export PYTHONHOME

4. 移植过程中遇到的问题：
root@mini2440:/work/rootfs/python# python2.6 test.py
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "test.py", line 2, in
    import os
ImportError: No module named os
答案：
在执行的过程中发想所有的python自带的py/pyc库文件找不到，是由于PYTHONHOME指定的路径有问题，和PYTHONHOME下文件架构有问题，一定为：${PYTHONHOME}/lib/python2.6（我是更具下面的调试信息找到问题原因的）。
