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.

Update
I've uploaded the python2.4 binary I built for Android. It's missing lots of libraries, but it runs :) I haven't corrected the build instructions yet, but I'll hopefully get to that soon.
