一系列折腾让我领教了系统库的缺失和不一致是一个多么糟糕的状况。尽管mips官方发布的NDK同时包含mips和arm交叉编译链，但我感觉mips的库支持状况比arm的差一些 。
1. 首先编译出本地的python和pgen：
./configure
make python Parser/pgen
mv python hostpython
mv Parser/pgen
make distclean
2. 给python2.7.2 打补丁

3. 配置环境
android-ndk 环境配置如下：
export ANDROID_NDK=”/root/android-ndk-r7bm/android-mips-9″
export PATH=”$ANDROID_NDK/bin:$PATH”
export CFLAGS=”-mips32r2 -DANDROID -mandroid -fomit-frame-pointer”
export CXXFLAGS=”$CFLAGS”
export CC=”mips-linux-android-gcc $CFLAGS”
export CXX=”mips-linux-android-g++ $CXXFLAGS”
export AR=”mips-linux-android-ar”
export RANLIB=”mips-linux-android-ranlib”
export STRIP=”mips-linux-android-strip –strip-unneeded”
export LD=”mips-linux-android-ld”
4. 编译配置参数如下
./configure LDFLAGS=”-Wl,–allow-shlib-undefined” CFLAGS=”-mips32r2 -DANDROID -mandroid -fomit-frame-pointer” HOSTPYTHON=/root/Python-2.7.2/hostpython HOSTPGEN=/root/Python-2.7.2/Parser/hostpgen –host=mips-linux –build=i686-pc-linux-gnu –enable-shared –prefix=/root/Python-2.7.2/_build
5. 编译参数设置如下
export MAKE=”make -j4 HOSTPYTHON=/root/Python-2.7.2/hostpython HOSTPGEN=/root/Python-2.7.2/Parser/hostpgen CROSS_COMPILE=mips-linux-android- CROSS_COMPILE_TARGET=yes”
链接过程中可见大量错误，多为某某函数未找到等等。可见android-mips 库函数的缺陷 。由于链接器加了–allow-shlib-undefined参数，所以最后编译链接都完成了。cp到目标机后可以打python –help ，但无法开启shell 也无法执行脚本。暂时先告一段落吧～～～ （无奈）

http://code.google.com/p/android-scripting/ SL4A 为android提供脚本支持的平台软件，包括python，perl，ruby等，当然不支持android-mips
http://pygame.renpy.org/ android上的python游戏平台软件。比较有价值的是提供了交叉编译python的脚本，但估计也只能在arm上编译通过。源码在这里https://launchpad.net/pgs4a （需要bzr 版本管理工具）
https://code.google.com/p/gaeproxy/downloads/list 使用python编写的gae代理，最大的特色是支持android ，当然也是for arm only
