Last week I did some fixes to PyPy 2.5-features branch because the translator was crashing. That’s because some of the code I wrote in the last four months were not RPython.
The changes were mostly to help the annotator (with assertions). Now you can have a pypy-c with full 2.5 support.
There are some bugs so stdlib may not be fully working. I’m working on that.
svn co http://codespeak.net/svn/pypy/branch/2.5-features/ pypy-2.5-features
cd pypy-2.5-features/pypy/translator/goal/
python translate.py targetpypystandalone --allworkingmodules
# wait........
./pypy-c
Please, read PyPy’s documentation on translating and if you find any problem while translating let me know. Note that this docs are for the trunk so some of the options may not be available in 2.5-features branch.
I wrote this post last week and it was in my drafts. Actually I fixed some other bugs (one related to PEP 352) and it seems that my changes broke the translator again. Talking in #pypy Armin said that this is probably a bug in the annotator. I don’t know much about the translation process or about the annotator… I guess it’s time to start looking at it
