python-arm-xcompile

This is a build script and patches for cross-compiling Python to target the ARM architecture.

You must have a cross-compile toolchain already set up. This guide is an excellent resource for setting up crosstool-ng.

1. Edit build.sh and change the variables at the top to match your environment.
2. Run build.sh. This will download Python and build it for you.

Assuming the build succeeds, a list of modules will be printed out. Some modules will not build statically since they need to be dynamically linked to glibc (TODO).

Python 2.7.4 unsupported

Note that Python 2.7.4 introduced breaking changes to _sre.MAXREPEATS that will fail to cross-compile statically. You must use 2.7.3 instead (for now) -- build.sh will download and extract this for you.
