Python on Itanium Windows 64: available or planned?

P: n/a
I am using Python on Itanium Windows 64 (Server 2003) with a Win32 version.

Is there a native version available or planned? Are testers needed for
this platform?

Windows 64 is a bit unusual in that "long" is not large enough to hold
an address.

Python should compile fine for Win64. It was ported for Win64 a few
years back (around the time of Python 2.0/1.6 I think).

There are no free binary packages kicking around out there that I know
of but a number of people do compile it themselves for Win64. There was
some discussion on this list recently about how to do that seeing as
there is no DevStudio for Win64 (at least, that is my understanding).
One way was to export makefiles from Python's .dsp project files and use
the Win64 cross-compiler that is available with the platform SDK.

Yup. Though I would use a stronger word than "unusual". :)

p.s. ActiveState will provide Win64 binary installers for Python on
contract, though I don't know if that is an option for you.

However, there are free binary packages out there that you don't know
of :-)

See

for the original announcement.

Again, it depends: With sf.net/projects/vsextcomp, VS 7.1 is very well
capable of invoking the Itanium platform SDK compiler (AMD64 coming
soon).

That may even be a source of bugs. I'm in the process of putting
size_t in every place Python currently uses "int" or "long" to store a
number of bytes. In some cases, exceeding 4GB (sometimes 2GB) will
cause crashes in Python 2.3 (in other cases, this is somewhat overkill
- eg. when the compiler complains that strlen(some_file_name) may not
fit into 4 bytes).
