Q. I want to port Python to a new platform. How do I begin?
|
|
|
|
A. 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" and "exceptions.py" by passing -X and -S
|
|
options.
|
|
|
|
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.
