cross-compiling Python 2.7.4+

问题


There are several tutorials on the web documenting how to cross-compile or cross-build Python for various embedded systems using some basic hacking and patching, like so:

http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html

This worked well for me in the past, when I was using Python 2.7.2.

In Python 2.7.4, some cross-compile functionality was finally included in the upstream build process, documented here:

  • http://bugs.python.org/issue17086
  • https://mail.python.org/pipermail/python-dev/2013-February/123779.html

This breaks all of the previous cross-build hacks, and I cannot find any updated tutorials or documentation for the new built-in cross-compile procedure.

Does anyone have a good example or documentation on using the new cross-compile procedure for Python 2.7.4 and onward in the 2.7 branch?

Thanks!

After diving into the existing patches and changes, I was able to produce a modified patch set that utilizes the latest cross-compiling features for 2.7.5.

Paul also references it on his original "classic" cross-compile-Python post:

For posterity...

Though the question is specifically about Python 2.7, if you're willing to step up to Python3, another option for embedded/micro with good cross-compiling features/support is Micro Python; (see also June 2014 announcement though it was around before that).

See also this other SO thread about small/portable (in multiple senses) Python implementations.
