안드로이드용 파이썬 제작하기
-----------------------------
 
Here's an early Christmas present for all those Python fanatics (self included) out there! With a lot of help from my friends (thanks Manuel and Thomas!) I managed to install Python 2.4.5 on my G1. It's still rough around the edges, but I think it's a good start. Klaus Reimer has a nice overview of how to cross-compile Python. My instructions borrow a lot from his.
  • Download and build the Android source. These directions assume that you have installed the source to /android_src.
  • Download and build the Python 2.4.5 source. These directions assume that you have installed the source to /python_src.
  • Make copies of python and pgen for use later in the build process then clean up.
$ cd /python_src
$ cp python hostpython
$ cp Parser/pgen Parser/hostpgen
$ make distclean
  • Apply the following patch to the Python source.

 안드로이드용으로 Python이 지원한다면 속도가 중요하지 않으면서 빨리 데모코드를 작성해야 하는 경우에 유용하게 될것 같습니다만, 큰 임팩트는 없을것 같습니다. 2000년도이 이광성 교수님이 파이썬 리더할대 나름 열광적으로 빠졌던적이 새록새록 합니다.ㅡ.ㅡ;;
