Maybe it's worth noting that IA64 (intel itanium) is an entirely different architecture than x86_64 and we do not support it. Please remove chekcing for this code.

April 23, 2013

Hi All, I have study PyPy's sandbox for some time.But as my limited ability,I can't understand the detail about the PyPy's sandbox. And I want to discuss something with you: 1.Cuted Modules What are the reasons to cut some standard modules? (I mean the modules which in 'working_modules' but not in 'default_modules'.'working_modules' and 'default_modules' are defined in /pypy/config/pypyoption.py) when generate C code,you use "excute" function's graph to replace the original function's graph,… [View More]

getting cppyy enabled by default in the next release?
by wlavrijsen＠lbl.gov April 23, 2013

April 23, 2013

Hi, what are my chances of getting cppyy enabled by default in the next (beta) release of pypy? The code has been cleaned so that no external libraries are needed when builing pypy-c, and none will be needed at run-time until "import cppyy". There is, however, an increase of 1.5MB in size of the pypy-c executable, but that should decrease when I can find more/better ways of reusing the code in _cfff_backend as-is. Currently, I'm working on updating the documentation and providing a tar file … [View More]

We finally have a buidlbot up and running own-windows-x86-32 tests. The page at http://buildbot.pypy.org/summary?builder=own-win-x86-32 is clogged with old results, could someone with superpowers please erase all build runs before 16.4.2013 ? Thanks, Matti

Hello, My name is Can Ibanoglu and I'm an industrial engineering student. I would like to get involved with the PyPy project, within the context of GSoC initially and hopefully beyond that. I have been interested in programming since I was 15 years old but I can't really say that I have been learning since then. I have always had some contact with programming since then but since the last two years I have been studying Python nonstop and trying to keep myself up to date with recent … [View More]
