[Nexus] Nexus with python on windows

[Akeroyd, FA (Freddie)]

Jon,

I've compiled the python binding for Windows and added a link to then
from
http://download.nexusformat.org/kits/windows/

These binding are swig based and provide a direct interface to the usual
NeXus API functions; I'm afraid there is currently no support for
Numeric/numpy

Regards,

Freddie

Subject: [Nexus] Nexus with python on windows

Dear NeXus'ers,

I've just downloaded the nexus api which is pre-built for windows from:

http://download.nexusformat.org/kits/windows/

These look useful, but I'm wondering where to find the python bindings. 
Is there a pre-compiled set around somewhere? Is it easier if I just use

PyTables for direct hdf access?

I did attempt to create a setup.py file for the ones in bindings/swig 
and build things myself but have gotten stuck. There are a lot of linker

errors coming from missing export libraries for the hdf dll's with mingw

(see below). Naturally, I have not been able to find the hdf ".a" 
libraries for mingw.

Whichever set of NeXus to python bindings, it seems neither supports the

Numeric or numpy packages for handling large arrays of binary data. Am I

missing something?

Thanks for your help,

Jon
