I guess the two things to start with is to familiarize yourself -with are the development system for your target platform and the -generic build process for Python. Make sure you can compile and run a -simple hello-world program on your target platform. Make sure you can -compile and run the Python interpreter on a platform to which it has -already been ported (preferably Unix, but Mac or Windows will do, -too). - -I also would never start something like this without at least -medium-level understanding of your target platform (i.e. how it is -generally used, how to write platform specific apps etc.) and Python -(or else you'll never know how to test the results). - -The build process for Python, in particular the Makefiles in the -source distribution, will give you a hint on which files to compile -for Python. Not all source files are relevant -- some are platform -specific, others are only used in emergencies (e.g. getopt.c). The -Makefiles tell the story. - -You'll also need a pyconfig.h file tailored for your platform. You can -start with pyconfig.h.in, read the comments and turn on definitions that -apply to your platform. - -And you'll need a config.c file, which lists the built-in modules you -support. Start with Modules/config.c.in. - -Finally, you'll run into some things that aren't supported on your -target platform. Forget about the posix module for now -- simply take -it out of the config.c file. - -Bang on it until you get a >>> prompt. (You may have to disable the -importing of "site.py" by passing the -S option.) - -Then bang on it until it executes very simple Python statements. - -Now bang on it some more. At some point you'll want to use the os -module; this is the time to start thinking about what to do with the -posix module. It's okay to simply #ifdef out those functions that -cause problems; the remaining ones will be quite useful. +This document is moved to https://docs.python.org/devguide/faq.html#how-do-i-port-python-to-a-new-platform |
