Hi, I am interested in working on Windows 7 64bit support for PyPy. Does anyone know what the best way to get started with this is? Is there a list of work that needs to be done to support Windows anywhere?
First - getting a buildbot running http://buildbot.pypy.org/builders/own-win-x86-64 <- this one has been down for quite a while Second - starting to make tests pass. On Tue, Aug 20, 2013 at 3:06 PM, Robert Grosse <n210241048576@gmail.com> wrote:
Hi all, I finally wrote out the details of what I think is a reasonable plan. https://bitbucket.org/pypy/pypy/raw/default/pypy/doc/windows.rst "What is missing for a full 64-bit translation" A bientôt, Armin.

It looks like CPython assumes the use of Visual Studio on Windows, but the express edition does not support 64bit compilation. Would it be feasible to use Mingw instead? I've looked around online, but it seems pretty discouraging. On Fri, Aug 23, 2013 at 1:40 PM, Armin Rigo <arigo@tunes.org> wrote:
Um, I believe you're mistaken. Though it's true that visual studio express doesn't *come * with a 64 bit compiler (at least on windows 7 and below, the latest one for win8 does) you can still download the windows 64 bit SDK and use the one that comes with that.

The tools provided by the windows SDK are the same tools that Visual Studio uses. In that capacity, VS is little more than a GUI for the underlying tools and configs.
