I can't seem to find the answer to this question anywhere. I'd just like to know, does the PyPy translate.py script produce 64bit or 32bit binary files? Is there an option to choose between the two that I'm missing or can PyPy only produce 32bit binaries?
RPython currently produces binaries according to the “host-Pyhton”, that is, typically a 32 bit binary on a 32 bit system and a 64 bit binary on a 64 bit system
However, to work cross-bit you can do the following:
If you have a 64 bit system
chroot environment [1,2,3,4] to produce a 32 bit one.If you have a 32 bit system
On OS X > 10.7, you typically have a 64 bit system so
use the environment variable VERSIONER_PYTHON_PREFER_32_BIT to control the “bitness” of python. For a 32 bit binary, you can run
PYTHONPATH=$PYPYPATH:… VERSIONER_PYTHON_PREFER_32_BIT=yes python $PYPYPATH/rpython/bin/rpython target….py
Note that you have to use python in this case (typically, rpython detects an installed pypy and uses that), because pypy does not respect the versioner variable and does not come as a 32 bit binary for OS X in the first place.
